The Kitāb al-Taṣrīf ( Arabic : كتاب التصريف لمن عجز عن التأليف , lit. 'The Arrangement of Medical Knowledge for One Who is Not Able to Compile a Book for Himself'), known in English as The Method of Medicine , is a 30-volume Arabic encyclopedia on medicine and surgery , written near the year 1000 by Abu al-Qasim al-Zahrawi (Abulcasis). It is available in translation. The Kitab al-Tasrif took al-Zahrawi over 50 years to complete. It contains information about a wide variety of illnesses, injuries, medical conditions, treatments, and surgical procedures. It describes over 200 different surgical instruments. Surgeons continued to rely on the Kitab al-Tasrif well into the 1700s.
133-502: The work covers a broad range of medical topics, including on surgery , medicine , orthopaedics , ophthalmology , pharmacology , nutrition , dentistry , childbirth , and pathology . The last treatise and the most celebrated one is about surgery. Al-Zahrawi stated that he chose to discuss surgery in the last volume because surgery is the highest form of medicine, and one must not practice it until he becomes well-acquainted with all other branches of medicine. On Surgery and Instruments
266-474: A radiosurgical procedure (e.g. irradiation of a tumor). Surgical procedures are commonly categorized by urgency, type of procedure, body system involved, the degree of invasiveness, and special instrumentation. Inpatient surgery is performed in a hospital, and the person undergoing surgery stays at least one night in the hospital after the surgery. Outpatient surgery occurs in a hospital outpatient department or freestanding ambulatory surgery center, and
399-525: A surgical procedure or surgical operation , or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments , surgical facility or surgical nurse . Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery. Modern surgical operations typically require
532-412: A surgical team that typically consists of the surgeon, the surgical assistant, an anaesthetist (often also complemented by an anaesthetic nurse ), a scrub nurse (who handles sterile equipment), a circulating nurse and a surgical technologist , while procedures that mandate cardiopulmonary bypass will also have a perfusionist . All surgical procedures are considered invasive and often require
665-486: A $ 12.3 trillion loss in economic productivity by the year 2030. This was especially true in the poorest countries, which account for over one-third of the population but only 3.5% of all surgeries that occur worldwide. It emphasized the need to significantly improve the capacity for Bellwether procedures – laparotomy , caesarean section , open fracture care – which are considered a minimum level of care that first-level hospitals should be able to provide in order to capture
798-495: A 0% mortality rate out of 401 laparoscopic cases, and 0.6% out of 955 open procedures. Similar mortality rates—30-day mortality of 0.11%, and 90-day mortality of 0.3%—have been recorded in the U.S. Centers of Excellence program, the results being from 33,117 operations at 106 centers. Mortality and complications are affected by pre-existing risk factors such as degree of obesity, heart disease, obstructive sleep apnea , diabetes mellitus , and history of prior pulmonary embolism . It
931-534: A 29% reduction in mortality up to 15 years following surgery (hazard ratio 0.71 when adjusted for sex, age, and risk factors), compared to a non-surgically treated group of 2037 patients. A meta-analysis of 174772 participants published in The Lancet in 2021 found that bariatric surgery was associated with 59% and 30% reduction in all-cause mortality among obese adults with or without type 2 diabetes respectively. This meta-analysis also found that median life-expectancy
1064-562: A BMI less than 18.5 considered underweight. The Consensus Panel of the National Institutes of Health (NIH) recommended the following criteria for consideration of bariatric surgery, including gastric bypass procedures: The Consensus Panel also emphasized the necessity of multidisciplinary care of the bariatric surgical patient by a team of physicians and therapists to manage associated comorbidities and nutrition, physical activity, behavior, and psychological needs. The surgical procedure
1197-489: A Component of Universal Health Coverage . The Lancet Commission for Global Surgery outlined the need for access to "available, affordable, timely and safe" surgical and anesthesia care; dimensions paralleled in ICESCR General Comment No. 14, which similarly outlines need for available, accessible, affordable and timely healthcare. Surgical treatments date back to the prehistoric era. The oldest for which there
1330-605: A component of universal health coverage." This not only mandated the WHO to prioritize strengthening the surgical and anesthesia care globally, but also led to governments of the member states recognizing the urgent need for increasing capacity in surgery and anesthesia. Additionally, the third edition of Disease Control Priorities (DCP3), published in 2015 by the World Bank , declared surgery as essential and featured an entire volume dedicated to building surgical capacity. Data from WHO and
1463-416: A consensus panel whose recommendations have set the current standard for consideration of surgical treatment, the body mass index (BMI). The BMI is defined as the body weight (in kilograms), divided by the square of the height (in meters). The result is expressed as a number in units of kilograms per square meter. In healthy adults, BMI ranges from 18.5 to 24.9, with a BMI above 30 being considered obese, and

The text also contains a number of innovations in dentistry, including using gold and silver wires to ligate loosened teeth, extracting and replanting teeth, and scaling the calculus from the teeth to prevent periodontal disease . Al-Zahrawi depicted over 200 surgical instruments , some of which he created himself. Instruments in the al-Tasrif include different kinds of scalpels , retractors , curettes , pincers , specula , and also instruments designed for his favoured techniques of cauterization and ligature . He also invented hooks with
1729-478: A distal GBP, fat-soluble vitamins A, D, and E may not be well-absorbed, particularly if fat intake is large. Water-dispersed forms of these vitamins may be indicated on specific physician recommendation. For some patients, sublingual B 12 is not enough, and patients may require B 12 injections. All versions of the GBP bypass the duodenum, which is the primary site of absorption of both iron and calcium. Iron replacement
1862-471: A double tip for use in surgery. The book was translated into Latin in the 12th century by Gerard of Cremona . It soon found popularity in Europe and became a standard text in universities like those of Salerno and Montpellier . It remained the primary source on surgery in Europe for the next 500 years, and as the historian of medicine, Arturo Castiglioni , has put it: al-Zahrawi's treatise "in surgery held
1995-437: A female post-operative gastric bypass patient who was consuming eight to ten 32 oz. glasses of ice a day. The patient's blood test revealed iron levels of 2.3 mmol/L and hemoglobin level of 5.83 mmol/L. Normal iron blood levels of adult women are 30 to 126 μg/dL and normal hemoglobin levels are 12.1 to 15.1 g/dL. This deficiency in the patient's iron levels may have led to the increase Pica activity. The patient
2128-401: A less irritating emollient, made of egg yolk , rose oil and turpentine . He also described more efficient techniques for the effective ligation of the blood vessels during an amputation . Gastric bypass Gastric bypass surgery refers to a technique in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch, where the small intestine
2261-444: A liquid protein supplement. Powdered protein supplements added to smoothies or any food can be an important part of the post-op diet. The profound weight loss which occurs after bariatric surgery is due to taking in much less energy (calories) than the body needs to use every day. Fat tissue must be burned to offset the deficit, and weight loss results. Eventually, as the body becomes smaller, its energy requirements are decreased, while
2394-520: A military physician". The researchers were impressed by the complexity of the brain surgical operation. In 1991 at the Polystylon fort in Greece, researchers discovered the head of a Byzantine warrior of the 14th century. Analysis of the lower jaw revealed that a surgery has been performed, when the warrior was alive, to the jaw which had been badly fractured and it tied back together until it healed. During
2527-513: A period of postoperative care (sometimes intensive care ) for the patient to recover from the iatrogenic trauma inflicted by the procedure. The duration of surgery can span from several minutes to tens of hours depending on the specialty , the nature of the condition, the target body parts involved and the circumstance of each procedure, but most surgeries are designed to be one-off interventions that are typically not intended as an ongoing or repeated type of treatment. In British colloquialism,
2660-498: A peripheral IV line is placed, and pre-operative medications (antibiotics, sedatives, etc.) are given. When the patient enters the operating room and is appropriately anesthetized, the team will then position the patient in an appropriate surgical position . If hair is present at the surgical site, it is clipped (instead of shaving). The skin surface within the operating field is cleansed and prepared by applying an antiseptic (typically chlorhexidine gluconate in alcohol, as this
2793-414: A person shows signs of infection and not as a preventative. A systematic review published by Cochrane (organisation) in 2016, though, concluded that topical antibiotics applied over certain types of surgical wounds reduce the risk of surgical site infections, when compared to no treatment or use of antiseptics . The review also did not find conclusive evidence to suggest that topical antibiotics increased
SECTION 20
#17328557321432926-403: A physical exam which did not indicate a chest x-ray. Routine x-ray examination is more likely to result in problems like misdiagnosis, overtreatment, or other negative outcomes than it is to result in a benefit to the person. Likewise, other tests including complete blood count , prothrombin time , partial thromboplastin time , basic metabolic panel , and urinalysis should not be done unless
3059-544: A prehistoric individual from the Indus River valley show evidence of teeth having been drilled. Sushruta Samhita is one of the oldest known surgical texts and its period is usually placed in the first millennium BCE. It describes in detail the examination, diagnosis, treatment, and prognosis of numerous ailments, as well as procedures for various forms of cosmetic surgery, plastic surgery and rhinoplasty . In 1982 archaeologists were able to find significant evidence when
3192-440: A recent study done with lumbar decompressions, the patient's length of stay was decreased by 1–3 days. The use of topical antibiotics on surgical wounds to reduce infection rates has been questioned. Antibiotic ointments are likely to irritate the skin, slow healing, and could increase risk of developing contact dermatitis and antibiotic resistance . It has also been suggested that topical antibiotics should only be used when
3325-502: A reduced relapse rate in Type 2 diabetes . However, RYGB was associated with a higher frequency of follow-up surgeries and hospitalizations due to complications. The gastric bypass, in its various forms, accounts for a large majority of the bariatric surgical procedures performed. It is estimated that 200,000 such operations were performed in the United States in 2008. Laparoscopic surgery
3458-447: A relatively modest increase in total weight loss. The mini-gastric bypass procedure was first developed by Robert Rutledge from the US in 1997, as a modification of the standard Billroth II procedure. A mini gastric bypass creates a long narrow tube of the stomach along its right border (the lesser curvature). A loop of the small gut is brought up and hooked to this tube at about 180 cm from
3591-454: A result of gastric bypass, and 0.5% of patients died within six months of surgery due to complications. A meta-analysis of 174,772 participants published in The Lancet in 2021 found that bariatric surgery was associated with 59% and 30% reduction in all-cause mortality among obese adults with or without type 2 diabetes respectively. This meta-analysis also found that median life-expectancy
3724-420: A result of the low acidity levels, patients can develop an overgrowth of bacteria. A study conducted on 43 post-operative patients revealed that almost all of the patients tested positive for a hydrogen breath test , which indicated an overgrowth of bacteria in the small intestine. Bacterial overgrowth causes the gut ecology to change and induces nausea and vomiting. Recurring nausea and vomiting eventually change
3857-466: A risk factor for adverse post-surgical outcomes. It has been linked to many disorders such as obesity hypoventilation syndrome, atelectasis and pulmonary embolism, adverse cardiovascular effects, and wound healing complications. If removable skin closures are used, they are removed after 7 to 10 days post-operatively, or after healing of the incision is well under way. It is not uncommon for surgical drains to be required to remove blood or fluid from

Prior to surgery, the person is given a medical examination , receives certain pre-operative tests, and their physical status is rated according to the ASA physical status classification system . If these results are satisfactory,
4123-629: A small volume of food, followed soon thereafter by a sense of satiety and loss of appetite. Total food intake is markedly reduced. Due to the reduced size of the newly created stomach pouch, and reduced food intake, adequate nutrition demands that the patient follow the surgeon's instructions for food consumption, including the number of meals to be taken daily, adequate protein intake, and the use of vitamin and mineral supplements. Calcium supplements, iron supplements, protein supplements, multi-vitamins (sometimes pre-natal vitamins are best), and vitamin B 12 (cyanocobalamin) supplements are all very important to

4256-636: A specialty of medicine, rather than an accessory field. Basic surgical principles for asepsis etc., are known as Halsteads principles . There were some important advances to the art of surgery during this period. The professor of anatomy at the University of Padua , Andreas Vesalius , was a pivotal figure in the Renaissance transition from classical medicine and anatomy based on the works of Galen , to an empirical approach of 'hands-on' dissection. In his anatomic treaties De humani corporis fabrica , he exposed
4389-425: A study conducted on 36 post-operative patients and a control group of 36 subjects (who had not undergone surgery), each subject drank a 5 oz. glass of red wine and had the alcohol in their breath measured to evaluate alcohol metabolism. The gastric bypass group had an average peak alcohol breath level at 0.08%, whereas the control group had an average peak alcohol breath level of 0.05%. It took on average 108 minutes for
4522-470: A weekend, and also, decrease number and level of experience over a weekend. Postoperative pain affects an estimated 80% of people who underwent surgery. While pain is expected after surgery, there is growing evidence that pain may be inadequately treated in many people in the acute period immediately after surgery. It has been reported that incidence of inadequately controlled pain after surgery ranged from 25.1% to 78.4% across all surgical disciplines. There
4655-402: Is a surgical connection between the stomach and bowel, or between two parts of the bowel. The surgeon attempts to create a water-tight connection by connecting the two organs with either staples or sutures, either of which actually makes a hole in the bowel wall. The surgeon will rely on the body's natural healing abilities and its ability to create a seal, like a self-sealing tire, to succeed with
4788-417: Is administered to prevent pain from the trauma of cutting, tissue manipulation, application of thermal energy, and suturing. Depending on the type of operation, anesthesia may be provided locally, regionally , or as general anesthesia . Spinal anesthesia may be used when the surgical site is too large or deep for a local block, but general anesthesia may not be desirable. With local and spinal anesthesia,
4921-425: Is also affected by the experience of the operating surgeon: the learning curve for laparoscopic bariatric surgery is estimated to be about 100 cases. Supervision and experience are important when selecting a surgeon, as the way a surgeon becomes experienced in dealing with problems is by encountering and solving them. Infection of the incisions or of the inside of the abdomen ( peritonitis , abscess ) may occur due to
5054-647: Is among the controversial topics related to surgery in children. Doctors perform surgery with the consent of the person undergoing surgery. Some people are able to give better informed consent than others. Populations such as incarcerated persons , people living with dementia , the mentally incompetent, persons subject to coercion, and other people who are not able to make decisions with the same authority as others, have special needs when making decisions about their personal healthcare, including surgery. Global surgery has been defined as 'the multidisciplinary enterprise of providing improved and equitable surgical care to
5187-536: Is an unpredictable failure or limitation of the surgery for certain patients (e.g. reactive hypoglycemia ). Any major surgery involves the potential for complications—adverse events that increase risk, hospital stay, and mortality. Some complications are common to all abdominal operations, while some are specific to bariatric surgery. The overall rate of complications during the 30 days following surgery ranges from 7% for laparoscopic procedures to 14.5% for operations through open incisions. One study on mortality revealed
5320-449: Is applied to the area of the person's body that will be operated on. Sterile drapes are placed around the operative site. Surgical masks are worn by the surgical team to avoid germs on droplets of liquid from their mouths and noses from contaminating the operative site. Work to correct the problem in body then proceeds. This work may involve: Blood or blood expanders may be administered to compensate for blood lost during surgery. Once
5453-444: Is being done to find a solution.As such, surgical care globally has been described as the 'neglected stepchild of global health,' a term coined by Paul Farmer to highlight the urgent need for further work in this area. Furthermore, Jim Young Kim , the former President of the World Bank , proclaimed in 2014 that "surgery is an indivisible, indispensable part of health care and of progress towards universal health coverage." In 2015,

5586-538: Is best regarded as a tool that enables the patient to alter lifestyle and eating habits, and to achieve effective and permanent management of obesity and eating behavior. Since 1991, major developments in the field of bariatric surgery, particularly laparoscopy , have outdated some of the conclusions of the NIH panel. In 2004 the American Society for Bariatric Surgery (ASBS) sponsored a consensus conference which updated
5719-476: Is clear in that following gastric bypass surgery, eating following stomach distension causes nausea, discomfort and vomiting, and so patients very quickly learn to avoid over eating, which is agreed to be the main cause of weight loss following the surgery. To gain the maximum benefit from this physiology, it is important that the patient eat only at mealtimes, 5 to 6 small meals daily, and not graze between meals. Concentration on obtaining 80–100 g of daily protein

Al-Zahrawi pioneered techniques of neurosurgery and neurological diagnosis, treating head injuries , skull fractures , spinal injuries , hydrocephalus , subdural effusions and headache . The first clinical description of an operative procedure for hydrocephalus was given by Al-Zahrawi, who clearly describes the evacuation of superficial intracranial fluid in hydrocephalic children. In Europe ,

Alternative forms of iron (fumarate, gluconate , chelates) are less irritating and probably better absorbed. Calcium carbonate preparations should also be avoided; calcium as citrate or gluconate (with 1200 mg as calcium) has greater bioavailability independent of acid in

Prehistoric surgical techniques are seen in Ancient Egypt , where a mandible dated to approximately 2650 BC shows two perforations just below the root of the first molar , indicating the draining of an abscessed tooth . Surgical texts from ancient Egypt date back about 3500 years ago. Surgical operations were performed by priests, specialized in medical treatments similar to today, and used sutures to close wounds. Infections were treated with honey. 9,000-year-old skeletal remains of

When the lumen of the small intestine comes into contact with nutrients, a number of hormones are released, including cholecystokinin from the duodenum and PYY and GLP-1 from the ileum . These hormones inhibit further food intake and have thus been dubbed "satiety factors". Ghrelin is a hormone that is released in

The ICESCR Article 12.1 and 12.2 define the human right to health as "the right of everyone to the enjoyment of the highest attainable standard of physical and mental health" In the August 2000, the UN Committee on Economic, Social and Cultural Rights (CESCR) interpreted this to mean "right to
6517-500: Is insufficient evidence to determine if giving opioid pain medication pre-emptively (before surgery) reduces postoperative pain the amount of medication needed after surgery. Postoperative recovery has been defined as an energy‐requiring process to decrease physical symptoms, reach a level of emotional well‐being, regain functions, and re‐establish activities. Moreover, it has been identified that patients who have undergone surgery are often not fully recovered on discharge. In 2011, of
6650-456: Is made to access the surgical site. Blood vessels may be clamped or cauterized to prevent bleeding, and retractors may be used to expose the site or keep the incision open. The approach to the surgical site may involve several layers of incision and dissection, as in abdominal surgery, where the incision must traverse skin, subcutaneous tissue, three layers of muscle and then the peritoneum. In certain cases, bone may be cut to further access
6783-428: Is markedly decreased in laparoscopic surgery. Abdominal surgery always results in some scarring of the bowel, called adhesions . A hernia, either internal or through the abdominal wall, may also result. When the bowel becomes trapped by adhesions or a hernia, it may become kinked and obstructed, sometimes many years after the original procedure. An operation is usually necessary to correct this problem. An anastomosis

#17328557321436916-504: Is necessary. Meals after surgery are 1 ⁄ 4 – 1 ⁄ 2 cup, slowly getting to 1 cup by one year. This requires a change in eating behavior and an alteration of long-acquired habits for finding food. In almost every case where weight gain occurs late after surgery, capacity for a meal has not greatly increased. Some assume the cause of regaining weight must be the patient's fault, e.g. eating between meals with high-caloric snack foods, though this has been debated. Others believe it
7049-403: Is performed using several small incisions, or ports : one to insert a surgical telescope connected to a video camera, and others to permit access to specialized operating instruments. The surgeon views the operation on a video screen. Laparoscopy is also called limited access surgery, reflecting the limitation on handling and feeling tissues and also the limited resolution and two-dimensionality of
7182-534: Is rearranged to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass procedures (GBP). Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food. The operation is prescribed to treat morbid obesity (defined as a body mass index greater than 40), type 2 diabetes , hypertension , sleep apnea , and other comorbid conditions. Bariatric surgery
7315-697: Is severely reduced, and vitamin content is correspondingly lowered. Supplements should therefore be taken to complete minimum daily requirements of all vitamins and minerals. Pre-natal vitamins are sometimes suggested by doctors, as they contain more of certain vitamins than most multi-vitamins. Absorption of most vitamins is not seriously affected after proximal GBP, although vitamin B 12 may not be well-absorbed in some persons: sublingual preparations of B 12 provide adequate absorption. Some studies suggest that GBP patients who took probiotics after surgery are able to absorb and retain higher amounts of B 12 than patients who did not take probiotics after surgery. After

Over time, the functional capacity of the pouch increases; by that time, weight loss has occurred, and the increased capacity should serve to allow maintenance of a lower body weight. When the patient ingests just a small amount of food, the first response is a stretching of
7847-471: Is the term encompassing all of the surgical treatments for morbid obesity, not just gastric bypasses, which make up only one class of such operations. The resulting weight loss, typically dramatic, markedly reduces comorbidities . The long-term mortality rate of gastric bypass patients has been shown to be reduced by up to 40%. As with all surgery, complications may occur. A study from 2005 to 2006 revealed that 15% of patients experienced complications as

9842-550: The ancient land, called 'Alahana Pirivena' situated in Polonnaruwa, with ruins, was excavated. In that place ruins of an ancient hospital emerged. The hospital building was 147.5 feet in width and 109.2 feet in length. The instruments which were used for complex surgeries were there among the things discovered from the place, including forceps, scissors, probes, lancets, and scalpels. The instruments discovered may be dated to 11th century AD. In ancient Greece , temples dedicated to
9975-434: The anesthesia, he/she is either transferred to a surgical ward elsewhere in the hospital or discharged home. During the post-operative period, the person's general function is assessed, the outcome of the procedure is assessed, and the surgical site is checked for signs of infection. There are several risk factors associated with postoperative complications, such as immune deficiency and obesity. Obesity has long been considered
10108-596: The beginning of the duodenum (first portion of the small intestine from the stomach) and the mid-jejunum (the secondary stage of the small intestine). This prevents the partially digested food from entering the first and initial part of the secondary stage of the small intestine, mimicking the effects of the biliopancreatic portion of Roux-en-Y gastric bypass (RYGB) surgery. Despite a handful of serious adverse events such as gastrointestinal bleeding, abdominal pain, and device migration – all resolved with device removal – initial clinical trials have produced promising results in
10241-410: The body to increase the coagulation of the blood. Simultaneously, activity may be reduced. Gastric Bypass Surgery is done with minimally invasive techniques (laparoscopy). Due to insufflation of the abdominal cavity with CO 2 for the surgery the venous return is diminished and this will lead to deep vein thrombosis of the lower extremities. There is an increased probability of the formation of clots in
10374-485: The bowel and is a cause of bowel obstruction. Antecolic antegastric Roux-en-Y gastric bypass surgery has been estimated to result in internal hernia in 0.2% of cases, mainly through Petersen's defect . An incisional hernia occurs when a surgical incision does not heal well; the muscles of the abdomen separate and allow protrusion of a sac-like membrane, which may contain bowel or other abdominal contents, and which can be painful and unsightly. The risk of abdominal-wall hernia
10507-1072: The common misconception that surgical care is financially prohibitive endeavor not worth pursuing in LMICs. A key policy framework that arose from this renewed global commitment towards surgical care worldwide is the National Surgical Obstetric and Anesthesia Plan (NSOAP). NSOAP focuses on policy-to-action capacity building for surgical care with tangible steps as follows: (1) analysis of baseline indicators, (2) partnership with local champions, (3) broad stakeholder engagement, (4) consensus building and synthesis of ideas, (5) language refinement, (6) costing, (7) dissemination, and (8) implementation. This approach has been widely adopted and has served as guiding principles between international collaborators and local institutions and governments. Successful implementations have allowed for sustainability in terms of longterm monitoring, quality improvement, and continued political and financial support. Access to surgical care
10640-414: The demand grew for surgeons to formally study for many years before practicing; universities such as Montpellier , Padua and Bologna were particularly renowned. In the 12th century, Rogerius Salernitanus composed his Chirurgia , laying the foundation for modern Western surgical manuals. Barber-surgeons generally had a bad reputation that was not to improve until the development of academic surgery as
10773-485: The enjoyment of a variety of facilities, goods, services, and conditions necessary for the realization of the highest attainable health". Surgical care can be thereby viewed as a positive right – an entitlement to protective healthcare. Woven through the International Human and Health Rights literature is the right to be free from surgical disease. The 1966 ICESCR Article 12.2a described the need for "provision for
10906-539: The establishment of the WHO Global Initiative for Emergency and Essential Surgical Care in 2005, the 2013 formation of the Lancet Commission for Global Surgery, the 2015 World Bank Publication of Volume 1 of its Disease Control Priorities Project "Essential Surgery", and the 2015 World Health Assembly 68.15 passing of the Resolution for Strengthening Emergency and Essential Surgical Care and Anesthesia as
11039-484: The evidence and the conclusions of the NIH panel. This conference, composed of physicians and scientists of both surgical and non-surgical disciplines, reached several conclusions, including: In recent comparisons with sleeve gastrectomy , gastric bypass has shown slightly better outcomes in diabetes remission and weight maintenance . According to a 2021 evidence update, Roux-en-Y gastric bypass (RYGB) patients were more likely to maintain weight loss over five years, with
11172-574: The gastric bypass patients group to return to an alcohol breath of zero, while it took the control group an average of 72 minutes. There have been reported cases in which pica recurs after gastric bypass in patients with a pre-operative history of the disorder, which are possibly due to iron deficiency . Pica is a compulsive tendency to eat substances other than normal food. Some examples would be people eating paper, clay, plaster, ashes, or ice. Low levels of iron and hemoglobin are common in patients who have undergone gastric bypass. One study reported on
11305-477: The greatest surgeons of the ancient world and performed many audacious operations – including brain and eye surgery – that were not tried again for almost two millennia. Hippocrates stated in the oath ( c. 400 BCE ) that general physicians must never practice surgery and that surgical procedures are to be conducted by specialists Researchers from the Adelphi University discovered in
11438-461: The healer-god Asclepius , known as Asclepieia ( Greek : Ασκληπιεία , sing. Asclepieion Ασκληπιείον ), functioned as centers of medical advice, prognosis, and healing. In the Asclepieion of Epidaurus , some of the surgical cures listed, such as the opening of an abdominal abscess or the removal of traumatic foreign material, are realistic enough to have taken place. The Greek Galen was one of
11571-594: The hospital, and are three times as likely to be discharged to a skilled nursing facility instead of to their own homes. People who are frail and elderly (score of 4 or 5) have even worse outcomes, with the risk of being discharged to a nursing home rising to twenty times the rate for non-frail elderly people. Surgery on children requires considerations that are not common in adult surgery. Children and adolescents are still developing physically and mentally making it difficult for them to make informed decisions and give consent for surgical treatments. Bariatric surgery in youth
11704-409: The indicated problem, minimize the risk of complications, optimize the time needed for recovery, and limit the surgical stress response. The intraoperative phase begins when the surgery subject is received in the surgical area (such as the operating theater or surgical department ), and lasts until the subject is transferred to a recovery area (such as a post-anesthesia care unit ). An incision
11837-427: The interior of the urethra and for removing foreign bodies from the throat, the ear, and other body organs. He was also the first to illustrate the various cannulae and to treat warts with an iron tube and caustic metal as a boring instrument. He describes what is thought to be the first attempt at reduction mammaplasty for the management of gynaecomastia and the first mastectomy to treat breast cancer . He
11970-490: The interior of the body; for example, cutting the skull for brain surgery or cutting the sternum for thoracic (chest) surgery to open up the rib cage . Whilst in surgery aseptic technique is used to prevent infection or further spreading of the disease. The surgeons' and assistants' hands, wrists and forearms are washed thoroughly for at least 4 minutes to prevent germs getting into the operative field, then sterile gloves are placed onto their hands. An antiseptic solution
12103-531: The intestines with gastric content in an attempt to dilute the sugars. An affected person may feel their heart beating rapidly and forcefully, break into a cold sweat, get a feeling of butterflies in the stomach, and may have an anxiety attack. The person usually has to lie down and could be very uncomfortable for 30–45 minutes. Diarrhea may then follow. Nutritional deficiencies are common after gastric bypass surgery, and are often not recognized. They include: After surgery, patients feel fullness after ingesting only
12236-458: The knowledge of it from them. Then through the whole of my life I have adhered to experience and practice…I have made it accessible for you and rescued it from the abyss of prolixity”. In the beginning of his book, al-Zahrawi states that the reason for writing this treatise was the degree of underdevelopment surgery had reached in the Islamic world, and the low status it was held by the physicians at
12369-445: The lower (distal) end of the small intestine, usually 100–150 cm (39–59 in) from the lower end, causing reduced absorption (malabsorption) of food: primarily of fats and starches, but also of various minerals and the fat-soluble vitamins. The unabsorbed fats and starches pass into the large intestine, where bacterial actions may act on them to produce irritants and malodorous gases. These larger effects on nutrition are traded for
12502-520: The lower stomach outlet and is re-arranged into a Y-configuration, enabling outflow of food from the small upper stomach pouch via a "Roux limb". In the proximal version, the Y-intersection is formed near the upper (proximal) end of the small intestine. The Roux limb is constructed using 80–150 cm (31–59 in) of the small intestine, preserving the rest (and the majority) of it from absorbing nutrients. The patient will experience very rapid onset of
12635-497: The many anatomical errors in Galen and advocated that all surgeons should train by engaging in practical dissections themselves. The second figure of importance in this era was Ambroise Paré (sometimes spelled "Ambrose" ), a French army surgeon from the 1530s until his death in 1590. The practice for cauterizing gunshot wounds on the battlefield had been to use boiling oil; an extremely dangerous and painful procedure. Paré began to employ
12768-575: The mechanisms of Roux-en-Y gastric bypass (RYGB) may not be correct. A growing body of evidence suggests that profound changes in body weight and metabolism resulting from RYGB cannot be explained by simple mechanical restriction or malabsorption. One study in rats found that RYGB induced a 19% increase in total and a 31% increase in resting energy expenditure , an effect not exhibited in vertical sleeve gastrectomy rats. In addition, pair-fed rats lost only 47% as much weight as their RYGB counterparts. Changes in food intake after RYGB only partially account for
12901-623: The most basic emergency surgical care. In terms of the financial impact on the patients, the lack of adequate surgical and anesthesia care has resulted in 33 million individuals every year facing catastrophic health expenditure – the out-of-pocket healthcare cost exceeding 40% of a given household's income. In alignment with the LCoGS call for action, the World Health Assembly adopted the resolution WHA68.15 in 2015 that stated, "Strengthening emergency and essential surgical care and anesthesia as
13034-508: The need for extended care. Assessment of older people before elective surgery can accurately predict the person's recovery trajectories. One frailty scale uses five items: unintentional weight loss, muscle weakness , exhaustion, low physical activity, and slowed walking speed. A healthy person scores 0; a very frail person scores 5. Compared to non-frail elderly people, people with intermediate frailty scores (2 or 3) are twice as likely to have post-surgical complications, spend 50% more time in
13167-531: The opening smaller. This is called a "stricture". Usually, the passage of food through an anastomosis will keep it stretched open, but if the inflammation and healing process outpaces the stretching process, scarring may make the opening so small that even liquids can no longer pass through it. The solution is a procedure called gastro endoscopy, and stretching of the connection by inflating a balloon inside it. Sometimes this manipulation may have to be performed more than once to achieve lasting correction. Ulceration of
13300-451: The operation due to associated benefits such as: a shortened hospital stay, reduced discomfort, shorter recovery time, less scarring, and minimal risk of incisional hernia . The gastric bypass procedure consists of: This variant is the most commonly employed gastric bypass technique, and is by far the most commonly performed bariatric procedure in the United States. The small intestine is divided approximately 45 cm (18 in) below
13433-439: The patient simultaneously finds it possible to eat somewhat more food. When the energy consumed is equal to the calories eaten, weight loss will stop. Proximal GBP typically results in loss of 60–80% of excess body weight, and very rarely leads to excessive weight loss. The risk of excessive weight loss is slightly greater with distal GBP. Vitamins are normally contained in foods and supplements. The amount of food eaten after GBP
13566-410: The person requiring surgery signs a consent form and is given a surgical clearance. If the procedure is expected to result in significant blood loss, an autologous blood donation may be made some weeks prior to surgery. If the surgery involves the digestive system , the person requiring surgery may be instructed to perform a bowel prep by drinking a solution of polyethylene glycol the night before
13699-585: The person who had surgery is discharged the same working day. Office-based surgery occurs in a physician's office, and the person is discharged the same day. At a hospital , modern surgery is often performed in an operating theater using surgical instruments , an operating table , and other equipment. Among United States hospitalizations for non-maternal and non-neonatal conditions in 2012, more than one-fourth of stays and half of hospital costs involved stays that included operating room (OR) procedures. The environment and procedures used in surgery are governed by
13832-410: The post-operative bypass patient. Total food intake and absorbance rate of food will rapidly decline after gastric bypass surgery, and the number of acid-producing cells lining the stomach increases. Doctors often prescribe acid-lowering medications to counteract the high acidity levels. Many patients then experience a condition known as achlorhydria , where there is not enough acid in the stomach. As
13965-413: The principles of aseptic technique : the strict separation of "sterile" (free of microorganisms) things from "unsterile" or "contaminated" things. All surgical instruments must be sterilized , and an instrument must be replaced or re-sterilized if it becomes contaminated (i.e. handled in an unsterile manner, or allowed to touch an unsterile surface). Operating room staff must wear sterile attire ( scrubs ,
14098-422: The procedure is complete, sutures or staples are used to close the incision. Once the incision is closed, the anesthetic agents are stopped or reversed, and the person is taken off ventilation and extubated (if general anesthesia was administered). After completion of surgery, the person is transferred to the post anesthesia care unit and closely monitored. When the person is judged to have recovered from
14231-444: The procedure. People preparing for surgery are also instructed to abstain from food or drink (an NPO order after midnight on the night before the procedure), to minimize the effect of stomach contents on pre-operative medications and reduce the risk of aspiration if the person vomits during or after the procedure. Some medical systems have a practice of routinely performing chest x-rays before surgery. The premise behind this practice
14364-479: The quality of life. Prior to 1991, clinicians interpreted serious obesity as weighing at least 100 pounds (45 kg) more than the "ideal body weight", an actuarially-determined body-weight at which one was estimated to be likely to live the longest, as determined by the life-insurance industry. This criterion failed for persons of short stature. In 1991, the National Institutes of Health (NIH) sponsored
14497-430: The recovery period. A recent post-operative care philosophy has been early ambulation. Ambulation is getting the patient moving around. This can be as simple as sitting up or even walking around. The goal is to get the patient moving as early as possible. It has been found to shorten the patient's length of stay. Length of stay is the amount of time a patient spends in the hospital after surgery before they are discharged. In
14630-457: The reduction of the stillbirth-rate and of infant mortality and for the healthy development of the child" which was subsequently interpreted to mean "requiring measures to improve… emergency obstetric services". Article 12.2d of the ICESCR stipulates the need for "the creation of conditions which would assure to all medical service and medical attention in the event of sickness", and is interpreted in
14763-413: The release of bacteria from the bowel during the operation. Nosocomial infections , such as pneumonia , bladder or kidney infections, and sepsis (blood-borne infection) are also possible. Effective short-term use of antibiotics, diligent respiratory therapy, and encouragement of activity within a few hours after surgery can reduce the risks of infections. Any injury, such as a surgical operation, causes
14896-447: The results of these tests can help evaluate surgical risk. A surgical team may include a surgeon, anesthetist, a circulating nurse, and a "scrub tech", or surgical technician, as well as other assistants who provide equipment and supplies as required. While informed consent discussions may be performed in a clinic or acute care setting, the pre-operative holding area is where documentation is reviewed and where family members can also meet
15029-523: The risk of local skin reactions or antibiotic resistance. Through a retrospective analysis of national administrative data, the association between mortality and day of elective surgical procedure suggests a higher risk in procedures carried out later in the working week and on weekends. The odds of death were 44% and 82% higher respectively when comparing procedures on a Friday to a weekend procedure. This "weekday effect" has been postulated to be from several factors including poorer availability of services on
15162-634: The same authority as did the Canon of Avicenna in medicine". Surgery Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass ), to reconstruct or improve aesthetics and appearance ( cosmetic surgery ), or to remove unwanted tissues ( body fat , glands , scars or skin tags ) or foreign bodies . The act of performing surgery may be called
15295-443: The so-called "noninvasive surgery" ought to be more appropriately called minimally invasive procedures , which usually refers to a procedure that utilizes natural orifices (e.g. most urological procedures) or does not penetrate the structure being excised (e.g. endoscopic polyp excision , rubber band ligation , laser eye surgery ), are percutaneous (e.g. arthroscopy , catheter ablation , angioplasty and valvuloplasty ), or to
15428-521: The start of the intestine. Numerous studies show that the loop reconstruction (Billroth II gastrojejunostomy) works more safely when placed low on the stomach, but can be a disaster when placed adjacent to the esophagus. Today thousands of "loops" are used for surgical procedures to treat gastric problems such as ulcers, stomach cancer, and injury to the stomach. The mini-gastric bypass uses the low set loop reconstruction and thus has rare chances of bile reflux. The MGB has been suggested as an alternative to
15561-477: The stomach feeling full, followed by a growing satiety (or "indifference" to food) shortly after the start of a meal. The small intestine is normally 20 - 22 ft (6 - 6.7 m) in length. As the Y-connection is moved further down the gastrointestinal tract, the amount available to fully absorb nutrients is progressively reduced, traded for greater effectiveness of the operation. The Y-connection is formed much closer to
15694-604: The stomach that stimulates hunger and food intake. Changes in circulating hormone levels after gastric bypass have been hypothesized to produce reductions in food intake and body weight in obese patients. However, these findings remain controversial, and the exact mechanisms by which gastric bypass surgery reduces food intake and body weight have yet to be elucidated. For example, it is still widely perceived that gastric bypass works by mechanical means, i.e. food restriction and/or malabsorption. Recent clinical and animal studies, however, have indicated that these long-held inferences about
15827-477: The stomach, and will likely be better absorbed. Chewable calcium supplements that include vitamin K are sometimes recommended by doctors as a good way to get calcium. Post-operative gastric bypass patients develop a lowered tolerance for alcoholic beverages because their altered digestive tract absorbs alcohol at a faster rate than people who have not undergone the surgery. It also takes a post-operative patient longer to reach sober levels after consuming alcohol. In
15960-501: The surgery. If that seal fails to form for any reason, fluid from within the gastrointestinal tract can leak into the sterile abdominal cavity and give rise to infection and abscess formation. Leakage of an anastomosis can occur in about 2% of Roux-en-Y gastric bypass and less than 1% in mini gastric bypass. Leaks usually occur at the stomach-intestine connection (gastro-jejunostomy). As the anastomosis heals, it forms scar tissue, which naturally tends to shrink ("contract") over time, making
16093-456: The surgical service line; the surgical service line costs were $ 17,600 in 2003 and projected to be $ 22,500 in 2013. For hospital stays in 2012 in the United States, private insurance had the highest percentage of surgical expenditure. in 2012, mean hospital costs in the United States were highest for surgical stays. Older adults have widely varying physical health. Frail elderly people are at significant risk of post-surgical complications and
16226-439: The surgical site is anesthetized, but the person can remain conscious or minimally sedated. In contrast, general anesthesia may render the person unconscious and paralyzed during surgery. The person is typically intubated to protect their airway and placed on a mechanical ventilator , and anesthesia is produced by a combination of injected and inhaled agents. The choice of surgical method and anesthetic technique aims to solve
16359-423: The surgical team. Nurses in the preoperative holding area confirm orders and answer additional questions of the family members of the patient prior to surgery. In the pre-operative holding area, the person preparing for surgery changes out of their street clothes and are asked to confirm the details of his or her surgery as previously discussed during the process of informed consent. A set of vital signs are recorded,
16492-601: The surgical wound during recovery. Mostly these drains stay in until the volume tapers off, then they are removed. These drains can become clogged, leading to abscess . Postoperative therapy may include adjuvant treatment such as chemotherapy , radiation therapy , or administration of medication such as anti-rejection medication for transplants. For postoperative nausea and vomiting (PONV), solutions like saline, water, controlled breathing placebo and aromatherapy can be used in addition to medication. Other follow-up studies or rehabilitation may be prescribed during and after
16625-713: The term "surgery" can also refer to the facility where surgery is performed, or simply the office / clinic of a physician , dentist or veterinarian . As a general rule, a procedure is considered surgical when it involves cutting of a person's tissues or closure of a previously sustained wound. Other procedures that do not necessarily fall under this rubric, such as angioplasty or endoscopy , may be considered surgery if they involve "common" surgical procedure or settings, such as use of antiseptic measures and sterile fields, sedation / anesthesia , proactive hemostasis , typical surgical instruments , suturing or stapling . All forms of surgery are considered invasive procedures;
16758-446: The time. Al-Zahrawi ascribed such decline to a lack of anatomical knowledge and a misunderstanding of the human physiology . Noting the importance of anatomy , he wrote: "Before practicing surgery one should gain knowledge of anatomy and the function of organs so that he will understand their shape, connections and borders. He should become thoroughly familiar with nerves muscles bones arteries and veins. If one does not comprehend
16891-511: The treatment's ability to improve weight loss and glucose homeostasis outcomes. The gastric bypass reduces the size of the stomach by well over 90%. A normal stomach can stretch, sometimes to over 1000 mL, while the pouch of the gastric bypass may be 15 mL in size. The gastric bypass pouch is usually formed from the part of the stomach which is least susceptible to stretching. That, and its small original size, prevents any significant long-term change in pouch volume. What does change, over time,
17024-449: The veins of the legs, or sometimes the pelvis, particularly in the morbidly obese patient. A clot that breaks free and floats to the lungs is called a pulmonary embolus, a very dangerous occurrence. Blood thinners are commonly administered before surgery to reduce the probability of this type of complication. Many blood vessels must be cut in order to divide the stomach and to move the bowel. Any of these may later begin bleeding, either into
17157-454: The video image. With experience, a skilled laparoscopic surgeon can perform most procedures as expeditiously as with an open incision—with the option of using an incision should the need arise. The Roux-en-Y laparoscopic gastric bypass , first performed and reported on in case studies between 1993 and 1994, is regarded as one of the most difficult procedures to perform by limited access techniques. The use of this method has greatly popularized
17290-436: The wall of the stomach pouch, stimulating nerves that tell the brain that the stomach is full. The patient feels a sensation of fullness, as if they had just eaten a large meal—but with just a thimble-full of food. Most people do not stop eating simply in response to a feeling of fullness, but the patient rapidly learns that subsequent bites must be eaten very slowly and carefully, to avoid increasing discomfort or vomiting. Food
17423-647: The world's population, with its core belief as the issues of need, access and quality". Halfdan T. Mahler , the 3rd Director-General of the World Health Organization (WHO) , first brought attention to the disparities in surgery and surgical care in 1980 when he stated in his address to the World Congress of the International College of Surgeons, "'the vast majority of the world's population has no access whatsoever to skilled surgical care and little
17556-530: Was 9.3 years longer for obese adults with diabetes who received bariatric surgery as compared to routine (non-surgical) care, whereas the life expectancy gain was 5.1 years longer for obese adults without diabetes. Gastric bypass is indicated for the surgical treatment of morbid obesity , a diagnosis which is made when the patient is seriously obese, has been unable to achieve satisfactory and sustained weight loss by dietary efforts, and has comorbid conditions which are either life-threatening or serious impairment to
17689-422: Was then given iron supplements that brought her hemoglobin and iron blood levels to normal levels. After one month, the patient's eating diminished to two to three glasses of ice per day. After one year of taking iron supplements the patient's iron and hemoglobin levels remained in a normal range and the patient reported that she did not have any further cravings for ice. Weight loss of 65–80% of excess body weight
