| endoscopic biopsy | Biopsy obtained by instruments passed through an endoscope or obtained by a needle introduced under endoscopic guidance. (05 Mar 2000) |
| endoscopic retrograde cholangiopancreatogram | A diagnostic procedure to examine diseases of the liver, bile ducts and pancreas. It is uncomfortable but not painful, is performed under intravenous sedation, usually without general anaesthesia, and has a low incidence of complications. ERCP provides important information unobtainable by other diagnostic means. Therapeutic measures can often be take at the time of ERCP to remove stones in the bile ducts or to relieve obstructions of the bile ducts. (12 Dec 1998) |
| endoscopic retrograde cholangiopancreatography | <investigation, procedure> A diagnostic-therapeutic procedure that involves the X-ray of the pancreatic duct and biliary tree after the selective introduction of a contrast material into the common bile duct and pancreatic duct. In this procedure, a flexible endoscope is passed through the mouth and down into the duodenum. A catheter is then passed through the endoscope and inserted into the pancreatic and bile ducts. It is uncomfortable but not painful, is performed under intravenous sedation, usually without general anaesthesia, and has a low incidence of complications. A contrast agent is injected into the catheter which highlights the coarse and calibre of the ducts. Narrowing, stones or ductal tumours can be identified with this procedure. Therapeutic measures can often be take at the time of ERCP to remove stones in the bile ducts or to relieve obstructions of the bile ducts, so that traditional open surgeries can be avoided. ERCP is increasingly accepted as the diagnostic and therapeutic procedure of choice in identifying and removing gallstones in the bile ducts. Acronym: ERCP (12 Dec 1998) |
| endoscopist | A specialist trained in the use of an endoscope. (05 Mar 2000) |
| endoscopy | <procedure> The visual inspection of any cavity of the body by means of an endoscope. (18 Nov 1997) |
| endoscopy, digestive system | Visual examination of the digestive tract by means of a fibreoptic endoscope. It is used to localise, identify, and photograph pathologic alterations, to obtain biopsy material and perform other surgical interventions, and for delivery of medication. (12 Dec 1998) |
| endoscopy, gastrointestinal | Visual examination of the gastrointestinal tract by means of a fibreoptic endoscope. It is used to localise, identify, and photograph pathologic alterations, to obtain biopsy material and perform other surgical interventions, and for delivery of medication. (12 Dec 1998) |
| endoscopy, upper | A procedure that enables the examiner (usually a gastroenterologist ) to examine the oesophagus (swallowing tube ), stomach, and duodenum ( first portion of small bowel ) using a thin flexible tube (a scope ) that can be looked through or seen on a TV monitor.
