98-406: Billroth II , more formally Billroth's operation II , is an operation in which a partial gastrectomy (removal of the stomach) is performed and the cut end of the stomach is closed. The greater curvature of the stomach (not involved with the previous closure of the stomach) is then connected to the first part of the jejunum in end-to-side anastomosis. The Billroth II always follows resection of

Percutaneous transluminal coronary angioplasty (PTCA) is contraindicated in patients with left main coronary artery disease, due to the risk of spasm of the left main coronary artery during the procedure. Also, PTCA is not recommended if there is less than 70% stenosis of the coronary arteries, as the stenosis it is not deemed to be hemodynamically significant below this level. Access to
294-474: 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
392-525: 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
490-412: 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
588-495: A vascular closure device . Transradial artery access (TRA) and transfemoral artery access (TFA) are two techniques for percutaneous coronary intervention. TRA is the technique of choice for management of acute coronary syndrome (ACS) as it has significantly lower incidence of bleeding and vascular complications compared with the TFA approach. TRA also has a mortality benefit for high risk ACS patients and high risk bleeding patients. TRA

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
784-489: 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
882-405: A balloon to open a blood vessel outside the coronary arteries. It is most commonly done to treat atherosclerotic narrowings of the abdomen, leg and renal arteries caused by peripheral artery disease . Often, peripheral angioplasty is used in conjunction with guide wire, peripheral stenting and an atherectomy . Angioplasty can be used to treat advanced peripheral artery disease to relieve
980-523: A catheter (a balloon catheter ) is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. The balloon forces expansion of the blood vessel and the surrounding muscular wall, allowing an improved blood flow. A stent may be inserted at the time of ballooning to ensure the vessel remains open, and the balloon is then deflated and withdrawn. Angioplasty has come to include all manner of vascular interventions that are typically performed percutaneously . A coronary angioplasty
1078-605: 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

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
1470-513: 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,
1568-498: 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
1666-414: 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
1764-403: 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

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
1960-440: 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
2058-466: 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.

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
2450-899: Is a modification of Billroth's operation called a partial gastrectomy with a Kronelein anastomosis where the divided end of the stomach is directly anastomosed to the side of the jejunal loop. Von Hacker was the first person to refer to the Billroth II partial gastrectomy operation writing from Billroth's clinic in 1885. 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 .

In 2012, the team members were honored with National Medal of Technology and Innovation by the President Barack Obama for their work related to the excimer laser. Robert Ginsburg deployed
7448-445: The lower part of the stomach ( antrum ). The surgical procedure is called a partial gastrectomy and gastrojejunostomy. The Billroth II is often indicated in refractory peptic ulcer disease and gastric adenocarcinoma . Over the years, the Billroth II operation has been colloquially referred to as any partial removal of the stomach with an end to side connection to the stomach as shown in the picture; however, technically, this picture
7546-497: 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
7644-623: 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
7742-508: 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
7840-410: 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
7938-585: 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
8036-413: 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 ,
8134-422: 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
8232-444: 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
8330-430: 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
8428-457: 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
8526-447: 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
8624-523: 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
8722-443: 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
8820-456: 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
8918-439: 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
9016-423: 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,
9114-601: 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
9212-713: 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;
9310-463: The vascular system is typically gained percutaneously (through the skin, without a large surgical incision). An introducer sheath is inserted into the blood vessel via the Seldinger technique . Fluoroscopic guidance uses magnetic resonance or X-ray fluoroscopy and radiopaque contrast dye to guide angled wires and catheters to the region of the body to be treated in real time. Tapered guidewire
9408-647: 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
9506-449: Was 'plain old balloon angioplasty' (POBA) without stenting, until the invention of bare metal stenting in the mid-1980s to prevent the abrupt closure sometimes seen with POBA. Bare metal stents were found to cause in-stent restenosis as a result of neointimal hyperplasia and stent thrombosis, which led to the invention of drug-eluting stents with anti-proliferative drugs to combat in-stent restenosis. The first coronary angioplasty with
9604-776: Was also found to yield improved quality of life, as well as decreased healthcare costs and resources. Relative to surgery , angioplasty is a lower-risk option for the treatment of the conditions for which it is used, but there are unique and potentially dangerous risks and complications associated with angioplasty: Angioplasty may also provide a less durable treatment for atherosclerosis and be more prone to restenosis relative to vascular bypass or coronary artery bypass grafting . Drug-eluting balloon angioplasty has significantly less restenosis, late lumen loss and target lesion revascularization at both short term and midterm follow-up compared to uncoated balloon angioplasty for femoropopliteal arterial occlusive disease. Although angioplasty of
