| cholangiopancreatography, endoscopic retrograde | Fibreoptic endoscopy designed for duodenal observation and cannulation of vater's ampulla, in order to visualise the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (vater) papillotomy (sphincterotomy, endoscopic) may be performed during this procedure. (12 Dec 1998) |

| haemostasis, endoscopic | Control of bleeding performed through the channel of the endoscope. Techniques include use of lasers, heater probes, bipolar electrocoagulation, and local injection. Endoscopic haemostasis is commonly used to treat bleeding oesophageal and gastrointestinal varices and ulcers. (12 Dec 1998) |
| sphincterotomy, endoscopic | Incision of oddi's sphincter or vater's ampulla performed by inserting a sphincterotome through an endoscope (duodenoscope) often following retrograde cholangiography (cholangiopancreatography, endoscopic retrograde). Endoscopic treatment by sphincterotomy is the preferred method of treatment for patients with retained or recurrent bile duct stones post-cholecystectomy, and for poor-surgical-risk patients that have the gallbladder still present. (12 Dec 1998) |
| surgical procedures, endoscopic | Surgery performed with the use of an endoscope. Operative techniques may include use of lasers or electrocautery. The procedure is guided via visualization using fibre optics, video and other remote transmission. Advantages are briefer anaesthesia and operative periods, reduced recovery time, shorter hospitalization, and generally less trauma for the patient. (12 Dec 1998) |
| 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) |
| hearing loss, functional | Hearing loss without a physical basis. (12 Dec 1998) |
| orthodontic appliances, functional | Loose, usually removable intra-oral devices which alter the muscle forces against the teeth and craniofacial skeleton. These are dynamic appliances which depend on altered neuromuscular action to effect bony growth and occlusal development. They are usually used in mixed dentition to treat paediatric malocclusions. (ada, 1992) (12 Dec 1998) |
| functional | 1. Pertaining to, or connected with, a function or duty; official. 2. <physiology> Pertaining to the function of an organ or part, or to the functions in general. <medicine> Functional disease, a disease of which the symptoms cannot be referred to any appreciable lesion or change of structure; the derangement of an organ arising from a cause, often unknown, external to itself opposed to organic disease, in which the organ itself is affected.
