cholangiocyte

(kŏ-lan′jĭ-ŏ-sīt″, kō-lan′jĭ-ŏ-sīt″) [cholangi- + -cyte] A bile duct epithelial cell.

cholangioenterostomy

(kō-lăn″jē-ō-ĕn″tĕr-ŏs′tō-mē) [″ + ″ + enteron, intestine, + stoma, mouth] Surgical formation of a passage between a bile duct and the intestine.

cholangiogastrostomy

(kō-lăn″jē-ō-găs-trŏs′tŏ-mē) [″ + ″ + gaster, stomach, + stoma, mouth] Surgical formation of a passage between a bile duct and the stomach.

cholangiography

(kŏ-lan″jē-og′ră-fē, kō″) [cholangio- + -graphy] Radiography of the bile ducts, now replaced by ultrasonography.

 percutaneous transhepatic c. ABBR: PTC. A radiologic examination involving direct percutaneous puncture of an intrahepatic duct by a needle inserted through the eighth or ninth intercostal space into the center of the liver. Radiopaque material is injected into the dilated intrahepatic biliary tree. The procedure is useful in determining the cause of obstructive jaundice. SEE: endoscopic retrograde cholangiopancreatography; jaundice.

cholangiole

cholangiolitis

 endoscopic retrograde c. ABBR: ERCP. Cholangiopancreatography following injection of a radiopaque material into the papilla of Vater. This is done through a fiberoptic endoscope guided by use of fluoroscopy. The procedure is helpful in determining the cause of obstructive jaundice. SEE: jaundice; percutaneous transhepatic cholangiography.

 magnetic resonance c. ABBR: MRCP. Cholangiopancreatography by magnetic resonance imaging, a noninvasive alternative to endoscopic retrograde cholangiopancreatography. It is used if biopsies are not needed and direct visualization of the ampulla of Vater is not required.

cholangiopathy

(kŏ-lan″jē-op′ă-thē) [cholangio- + -pathy] Any disease of the bile ducts.

cholangioscopy

(kŏ-lan″jē-os′kŏ-pē, kō″) [cholangio- + -scopy] Endoscopic evaluation of the lumen (the inside) of the bile ducts.
