| cholangioma | <oncology, tumour> A tumour of the bile ducts. (27 Sep 1997) |
|---|---|
| cholangiopancreatography | Radiographic examination of the bile ducts and pancreas. (05 Mar 2000) |
| 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) |

| cholangitis, sclerosing | Chronic, nonbacterial inflammatory narrowing of the bile ducts. About 50% of the cases are associated with ulcerative colitis. Treatment is to relieve the obstruction by balloon dilatation or surgery. (12 Dec 1998) |
| cholanic acid | A family of steroids comprising the bile acids (or salts), generally in conjugated form (e.g., glycocholic and taurocholic acids). Chemically, cholic acids are cholan-24-oic (cholanic) acids (the terminal C24 of cholane becoming a -COOH group); biologically, cholic acids are derived from cholesterol (a cholestane derivative) and display varying degrees of oxidation (OH groups) and orientation at positions 3, 7, and 12. It is these oxidations and orientations that distinguish the several cholic acid; e.g., cholic acid is 3a,7a,12a-trihydroxy-5b-cholan-24-oic acid, deoxycholic acid is 3a,12a-dihydroxy-5b-cholanic acid. Synonym: cholalic acid, cholanic acid. (05 Mar 2000) |
