39-456: Maurice Bucaille ( French pronunciation: [moris bykaj] ; 19 July 1920 – 17 February 1998) was a French doctor known primarily for his book The Bible, The Qur'an and Science . Maurice Bucaille was a specialist in the field of gastroenterology . In 1973, he was appointed as the family physician of Faisal of Saudi Arabia . His patients included the members of the family of Egyptian President Anwar Sadat . In 1976, Bucaille published

78-476: A H. pylori infection. Intra-operative techniques can then be used for treatment of certain disorders like banding esophageal varices or dilating esophageal strictures. The patient will likely be required to not eat or drink anything starting 4 hours prior to the procedure. Sedation is usually required for patient comfort. This procedure usually lasts around thirty minutes followed by a one to two hour observation period. Side effects include bloating , nausea, and

117-478: A long thin tube with a camera that is passed through the anus to visualize the rectum and the entire length of the colon. The procedure is performed either to look for colon polyps and/or colon cancer in somebody without symptoms, referred to as screening , or to further evaluate symptoms including rectal bleeding , dark tarry stools , change in bowel habits or stool consistency (diarrhea, pencil-thin stool), abdominal pain, and unexplained weight loss. Before

156-847: A "fourth-year" (although this is often their seventh year of graduate medical education) in transplant hepatology , advanced interventional endoscopy , inflammatory bowel disease , motility , or other topics. Advanced endoscopy, sometimes called interventional or surgical endoscopy, is a sub-specialty of gastroenterology that focuses on advanced endoscopic techniques for the treatment of pancreatic , hepatobiliary , and gastrointestinal disease . Interventional gastroenterologists typically undergo an additional year of rigorous training in advanced endoscopic techniques including endoscopic retrograde cholangiopancreatography, endoscopic ultrasound-guided diagnostic and interventional procedures, and advanced resection techniques including endoscopic mucosal resection and endoscopic submucosal dissection . Additionally,

195-590: A book titled The Bible, The Qur'an and Science following his study of the mummy of the Egyptian pharaoh Ramesses II . The book contained multiple references to the Quran , relating science and Quran in which Bucaille concluded that the Quran is a divine revelation and that it was not written by any man. The book gave rise to a movement called Bucailleism, which tries to relate modern science with religion, especially Islam . Since

234-434: A colonoscopy using a long thin tube with a camera (scope) passed through the anus but only intended to visualize the rectum and the last part of the colon closest to the rectum. All aspects of the procedure are the same as for a colonoscopy with the exception that this procedure only lasts ten to twenty minutes and is done without sedation. This usually allows for the patient to return to normal activities immediately after

273-435: A family history of this disorder, belly fat , and a history of smoking. Protective factors include H. pylori infection , frequent use of aspirin or other non-steroidal anti-inflammatory drugs , and diets high in fruits and vegetables. Diagnosis can be made by looking into the esophagus with a scope and possibly taking a biopsy of the lining of the esophagus. Treatment includes managing GERD, destroying abnormal parts of

312-399: A large amount of blood loss, patients may present with anemia or low blood pressure. However, aside from the melena itself, many patients may present with few symptoms. Often, the first approach is to use endoscopy to look for obvious signs of a bleed. In cases where the source of the bleed is unclear, but melena is present, an upper endoscopy is recommended, to try to ascertain the source of

351-579: A number of medications, such as bismuth subsalicylate (the active ingredient in Pepto-Bismol ), or by foods such as beetroot , black liquorice , or blueberries. The most common cause of melena is peptic ulcer disease. However, any bleeding within the upper gastrointestinal tract or the ascending colon can lead to melena. Melena may also be a complication of anticoagulant medications, such as warfarin . Causes of upper gastrointestinal bleeding that may result in melena include malignant tumors affecting

390-411: A one to two hour observation period. Complications include bloating, cramping, a reaction to anesthesia, bleeding, and a hole through the wall of the colon that may require repeat colonoscopy or surgery. Signs of a serious complication requiring urgent or emergent medical attention include severe pain in the abdomen, fever, bleeding that does not improve, dizziness, and weakness. A procedure similar to

429-476: A real time view, via fluoroscopy , allowing the physician to locate and relieve the blockage. This is done through multiple techniques including cutting the opening and creating a bigger hole for drainage, removing gallstones and other debris, dilating narrow parts of the ducts, or placing a stent which keeps the ducts open. The physician can also take a biopsy of the ducts to evaluate for cancer, infection, or inflammation. Side effects include bloating, nausea, or

468-417: A result of gallstones , infection, inflammation, pancreatic pseudocysts , and tumors of the bile ducts or pancreas. As a result, one may experience back pain, yellowing of the skin , and an abnormal lab test showing an elevated bilirubin level which could necessitate this procedure. However, the procedure is not recommended if the patient has acute pancreatitis unless the level of bilirubin remains high or

507-400: A sore throat for 1 to 2 days. Complications are rare but include reaction to the anesthesia, bleeding, and a hole through the wall of the esophagus, stomach, or small intestine which could require surgery. Signs of a serious complication requiring urgent or emergent medical attention include chest pain, problems breathing, problems swallowing, throat pain that gets worse, vomiting with blood or

546-532: A sore throat for one to two days. Complications include pancreatitis , infection of the bile ducts or gallbladder , bleeding, reaction to the anesthesia, and perforation of any structures that the scope or its instruments pass but particularly the duodenum, bile duct, and pancreatic duct. Signs of a serious complication requiring urgent or emergent medical attention include bloody or black tarry stool , chest pain, fever, worsening abdominal pain, worsening throat pain, problems breathing, problems swallowing, vomit that

585-430: Is a form of blood in stool which refers to the dark black, tarry feces that are commonly associated with upper gastrointestinal bleeding . The black color and characteristic strong odor are caused by hemoglobin in the blood being altered by digestive enzymes and intestinal bacteria . Iron supplements may cause a grayish-black stool that should be distinguished from melena, as should black coloration caused by

624-706: Is a subspecialty of internal medicine and therefore requires three years of internal medicine residency training followed by three additional years in a dedicated gastroenterology fellowship . This training is certified by the American Board of Internal Medicine (ABIM) and the American Osteopathic Board of Internal Medicine (AOBIM) and must be completed at a program accredited by the Accreditation Council for Graduate Medical Education (ACGME). Other national societies that oversee training include

663-429: Is also performed for further testing following a lab test that shows low hemoglobin levels without a known cause or an abnormal barium swallow . The procedure can be used to diagnose many disorders through direct visualization or tissue biopsy including esophageal varices , esophageal strictures , gastroesophageal reflux disease , Barrett's esophagus , cancer, celiac disease , gastritis , peptic ulcer disease , and

702-405: Is associated with melena. For this reason, melena is often associated with blood in the stomach or duodenum ( upper gastrointestinal bleeding ), for example by a peptic ulcer . A rough estimate is that it takes about 14 hours for blood to be broken down within the intestinal lumen; therefore if transit time is less than 14 hours the patient will have hematochezia, and if greater than 14 hours

741-405: Is bloody or looks like coffee-grounds . Most of the time complications from this procedure require hospitalization for treatment. A condition that is a result of stomach contents consistently coming back up into the esophagus causing troublesome symptoms or complications. Symptoms are considered troublesome based on how disruptive they are to a patient's daily life and well-being. This definition

780-447: Is increasing which could suggest the blockage is still present. The patient will likely be required to not eat or drink anything starting 8 hours prior to the procedure. After the patient is sedated, the physician will pass the scope through the mouth, esophagus, stomach, and into the duodenum to locate the opening where the ducts drain into the small intestine . The physician can then inject dye into these ducts and take X-rays which show

819-422: Is often first line, however. Bleeds that originate from the lower gastrointestinal tract (such as the sigmoid colon and rectum ) are generally associated with the passage of bright red blood, or hematochezia , particularly when brisk. Only blood that originates from a more proximal source (such as the small intestine ), or bleeding from a lower source that occurs slowly enough to allow for enzymatic breakdown,

858-451: Is stool remaining in the colon due to an incomplete bowel prep because the physician can not adequately visualize the colon. During the procedure, the patient is sedated and the scope is used to examine the entire length of the colon looking for polyps, bleeding, or abnormal tissue. A biopsy or polyp removal can then be performed and the tissue sent to the lab for evaluation. The procedure usually takes thirty minutes to an hour followed by

897-479: Is usually based on symptoms and medical history, with further testing only after treatment has been ineffective. Further diagnosis can be achieved by measuring how much acid enters the esophagus or looking into the esophagus with a scope . Treatment and management options include lifestyle modifications, medications, and surgery if there is no improvement with other interventions. Lifestyle modifications include not lying down for three hours after eating, lying down on

936-787: The American College of Gastroenterology (ACG), the American Gastroenterological Association (AGA), and the American Society for Gastrointestinal Endoscopy (ASGE). Gastroenterologists see patients both in the clinic and the hospital setting. They can order diagnostic tests, prescribe medications, and perform a number of diagnostic and therapeutic procedures including colonoscopy , esophagogastroduodenoscopy (EGD), endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound (EUS), and liver biopsy . Some gastroenterology trainees will complete

975-918: The GI tract via peristalsis , break down that material via digestion , absorb nutrients for use throughout the body, and remove waste from the body via defecation . Physicians who specialize in the medical specialty of gastroenterology are called gastroenterologists or sometimes GI doctors . Some of the most common conditions managed by gastroenterologists include gastroesophageal reflux disease , gastrointestinal bleeding , irritable bowel syndrome , inflammatory bowel disease (IBD) which includes Crohn's disease and ulcerative colitis , peptic ulcer disease , gallbladder and biliary tract disease, hepatitis , pancreatitis , colitis , colon polyps and cancer , nutritional problems, and many more. Citing from Egyptian papyri , John F. Nunn identified significant knowledge of gastrointestinal diseases among practicing physicians during

1014-451: The appearance of " coffee-grounds ", worsening abdominal pain, bloody or black tarry stool, and fever. A procedure using a long thin tube with a camera passed through the mouth into the first part of the small intestine to locate, diagnose, and treat disorders related to the bile and pancreatic ducts . These ducts carry fluids that help with digesting food from the liver, gallbladder, and pancreas and can become narrowed or blocked as

1053-398: The bleed. Lower gastrointestinal bleeding sources usually present with hematochezia or frank blood. A test with poor sensitivity/specificity that may detect the source of bleeding is the tagged red blood cell scan. This is especially used for slow bleeding (<0.5 ml/min). However, for rapid bleeding (>0.5 ml/min), mesenteric angiogram ± embolization is the gold standard. Colonoscopy

1092-522: The diet, as with consumption of black pudding (blood sausage), or with the traditional African Maasai diet, which includes much blood drained from cattle. Melena is considered a medical emergency as it arises from a significant amount of bleeding. Urgent care is required to rule out serious causes and prevent potentially life-threatening emergencies. A less serious, self-limiting case of melena can occur in newborns two to three days after delivery, due to swallowed maternal blood. In acute cases, with

1131-408: The esophagus that may cause bleeding or ulcer formation, narrowing of the esophagus leading to swallowing issues, a change in the lining of the esophagus that can increase the chances of developing cancer ( Barrett's esophagus ), chronic cough, asthma, inflammation of the larynx leading to hoarseness, and wearing away of tooth enamel leading to dental issues. A condition in which the lining of

1170-403: The esophagus changes to look more like the lining of the intestine and increases the risk of developing esophageal cancer . There are no specific symptoms although symptoms of GERD may be present for years prior as it is associated with a 10–15% risk of Barrett's esophagus. Risk factors include chronic GERD for more than 5 years, being age 50 or older, being non-Hispanic white, being male, having

1209-436: The esophagus, removing abnormal tissue in the esophagus, and removing part of the esophagus as performed by a general surgeon. Further management could include periodic surveillance with repeat scopes at certain intervals determined by the physician, likely not more frequently than every three to five years. Complications from this disorder can result in a type of cancer called esophageal adenocarcinoma . Gastroenterology

A procedure using a long thin tube with a camera that is passed through the mouth to view the esophagus ("esophago-"), stomach ("gastro-"), and the duodenum ("duodeno-"). It is also referred to as upper endoscopy or just endoscopy. The procedure is performed for further evaluation of symptoms including persistent heartburn , indigestion , vomiting blood , dark tarry stools , persistent nausea and vomiting, pain, difficulty swallowing , painful swallowing , and unexplained weight loss. It
