DiverticulitisHinchey Classification: Hinchey Classification is used to describe perforations of the colon due to diverticulitis.Sigmoidocele: Sigmoidocele (also known as Pouch of Douglas descent) refers to a condition where the sigmoid colon descends (prolapses) into the lower pelvic cavity. This can obstruct the rectum and cause symptoms of obstructed defecation.Ileosigmoid knot: An ileosigmoid knot is a form of volvulus in which ileum wraps around the base of the sigmoid and passes beneath itself forming a knot.Gastrointestinal perforationDiverticulosisDiverticulum: A diverticulum (plural: diverticula) is the medical or biological term for an outpouching of a hollow (or a fluid-filled) structure in the body. Depending upon which layers of the structure are involved, they are described as being either true or false.ColectomyColostomyPneumaturia: Pneumaturia is the passage of gas or "air" in urine. This may be seen or described as "bubbles in the urine".Barium sulfate suspension: Barium sulfate suspension is barium sulfate powder turned into a liquid form by suspending it in a quick-flowing drink to aid in CT scans of the gastrointestinal region.AppendicitisMalone antegrade continence enema: right|300px|thumb|The [[vermiform appendix is typically used in the Malone antegrade continence enema.]]List of eponymous surgical procedures: Eponymous surgical procedures are generally named after the surgeon or surgeons who performed or reported them first. In some instances they are named after the surgeon who popularised them or refined existing procedures, and occasionally are named after the patient who first underwent the procedure.Sectional Appendix: In Great Britain, the Sectional Appendix is a railway document compiled by Network Rail and is the official definition of railway infrastructure, giving a detailed description of all railway lines owned by Network Rail. It has traditionally been published in printed format, originally as a bound book and subsequently in loose-leaf format, for ease of updating.Alternative technology: Alternative technology is a term used to refer to technologies that are more environmentally friendly than the functionally equivalent technologies dominant in current practice.Johann Friedrich MeckelSpontaneous bacterial peritonitisThe Society of Elite Laparoscopic Surgeons: The Society of Elite Laparoscopic Surgeons is a non-profit organization based in Chandler, AZ, existing for the purpose of promoting access to minimally invasive surgery in the United States, and to lobby and promote the transition of the US medical system to adopt minimally invasive hysterectomy as standard of care.Society of Elite Laparoscopic Surgeons The organization is made up of member gynecologic surgeons, and holds annual meetings in various locales.Diagnostic peritoneal lavageStrictureplasty: Strictureplasty (also spelled Stricturoplasty) is a surgical procedure performed in response to scar tissue that has built up in the intestinal wall from inflammatory bowel conditions such as Crohn's disease. The scar tissue accumulates as a result of repeated damage and healing, with the scarring causing a stricture (a narrowing of the lumen of the bowel).Epiploic appendagitis: Epiploic appendagitis (EA) is an uncommon, benign, non-surgical, self-limiting inflammatory process of the epiploic appendices. Other, older terms for the process include appendicitis epiploica and appendagitis, but these terms are used less now in order to avoid confusion with acute appendicitis.Dense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.Virtual colonoscopy: Virtual colonoscopy (VC, also called CT Colonography or CT Pneumocolon) is a medical imaging procedure which uses x-rays and computers to produce two- and three-dimensional images of the colon (large intestine) from the lowest part, the rectum, all the way to the lower end of the small intestine and display them on a screen. The procedure is used to diagnose colon and bowel disease, including polyps, diverticulosis and cancer.Glasgow-Blatchford score: The Glasgow-Blatchford bleeding score (GBS) is a screening tool to assess the likelihood that a patient with an acute upper gastrointestinal bleeding (UGIB) will need to have medical intervention such as a blood transfusion or endoscopic intervention. The tool may be able to identify patients who do not need to be admitted to hospital after a UGIB.Chamber reamer: A chamber reamer is a specific type of fluted reamer used by gunsmiths and firearms manufacturers to cut the chamber of a handgun, rifle, or shotgun. The chamber reamer is inserted into the bore of a barrel and held stationary while the barrel is turned around it (typically by means of a lathe).Laparotomy
