| biliary stricture | <gastroenterology, surgery> An abnormal narrowing of the common bile duct. A potential cause for biliary obstruction. Risk factors are prior surgery, pancreatitis, trauma and gallstones. Symptoms include jaundice, fever, chills and abdominal pain. Endoscopic surgery has been successful in removing strictures of the bile duct. (27 Sep 1997) |
|---|---|
| biliary tract | <anatomy> The biliary tract refers to the bile ducts within the liver, the common bile duct (connecting the liver and gallbladder to the small intestine) and the cystic duct (short duct that connects the common bile duct to the gallbladder). Blockage in any location in the biliary tract can result in obstructive jaundice. (27 Sep 1997) |
| biliary tract surgical procedures | Any surgical procedure performed on the biliary tract. (12 Dec 1998) |
| biliary xanthomatosis | Xanthomatosis with hypercholesterolaemia, resulting from biliary cirrhosis. Synonym: Rayer's disease. (05 Mar 2000) |
| glands of biliary mucosa | Small, mucous, tubuloalveolar glands in the mucosa of the larger bile ducts and especially in the neck of the gallbladder. Synonym: glandulae mucosae biliosae, Luschka's cystic glands, Theile's glands. (05 Mar 2000) |
| primary biliary cirrhosis | <gastroenterology> A rare form of liver disease which results in the irreversible destruction of the liver and bile ducts. The cause is unknown, but is thought to be an autoimmune mechanism. (06 Mar 1998) |
| equine biliary fever | <veterinary> A disease of horses caused by species of Babesia and characterised by high fever, icterus, and enlargement of the spleen and lymph nodes. Synonym: biliary fever of horses, equine biliary fever. (05 Mar 2000) |
| liver cirrhosis, biliary | Liver cirrhosis in which there is interference with intrahepatic bile flow. It includes primary biliary cirrhosis, an intrahepatic disturbance of bile secretion affecting predominantly middle-aged women and with segmental destruction and, later, absence of septal bile ducts (cirrhosis is the end stage); and secondary biliary cirrhosis, which is produced by prolonged mechanical obstruction of large intrahepatic or extrahepatic bile ducts. (12 Dec 1998) |
| abdominal part of thoracic duct | The part of the thoracic duct between the cisterna chyli and the aortic hiatus of the diaphragm. Synonym: pars abdominalis ductus thoracici. (05 Mar 2000) |
| accessory pancreatic duct | The excretory duct of the head of the pancreas, one branch of which joins the pancreatic duct, the other opening independently into the duodenum at the lesser duodenal papilla. Synonym: ductus pancreaticus accessorius, Bernard's canal, Bernard's duct, ductus dorsopancreaticus, Santorini's canal, Santorini's duct. (05 Mar 2000) |
| adenoma, bile duct | A benign tumour of the intrahepatic bile ducts. (12 Dec 1998) |
| alveolar duct | The part of the respiratory passages distal to the respiratory bronchiole; from it arise alveolar sacs and alveoli, the smallest of the intralobular duct's in the mammary gland, into which the secretory alveoli open. Synonym: ductulus alveolaris. (05 Mar 2000) |
| alveolar duct emphysema | Emphysema in which the primary involvement is in the alveolar ducts and respiratory bronchioles, as opposed to panacinar emphysema. (05 Mar 2000) |
| amniotic duct | The transitory opening between the seroamniotic folds in birds just before they fuse to form the seroamniotic raphe. (05 Mar 2000) |
| ampulla of milk duct | A circumscribed spindle-shaped dilation of the lactiferous duct just before it enters the nipple. In nursing mothers this dilatation stores a droplet of milk which is expressed by compression as the infant begins to suckle; this is thought to encourage continual suckling while the let-down reflex ensues. Synonym: sinus lactiferi, ampulla lactifera, ampulla of milk duct, lactiferous ampulla. (05 Mar 2000) |
