Cholangiocyte: Cholangiocytes are the epithelial cells of the bile duct. They are cuboidal epithelium in the small interlobular bile ducts, but become columnar and mucus secreting in larger bile ducts approaching the porta hepatis and the extrahepatic ducts.Common bile duct: The common bile duct (), sometimes abbreviated CBD, is a tube-like anatomic structure in the gastrointestinal tract of organisms that have a gall bladder. It is formed by the union of the common hepatic duct and the cystic duct (from the gall bladder).Bile: Bile or gall is a dark green to yellowish brown fluid, produced by the liver of most vertebrates, that aids the digestion of lipids in the small intestine. In humans, bile is produced continuously by the liver (liver bile), and stored and concentrated in the gallbladder (gallbladder bile).Bile acid malabsorptionPancreatic duct: The pancreatic duct, or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct), is a duct joining the pancreas to the common bile duct to supply pancreatic juices which aid in digestion provided by the exocrine pancreas. The pancreatic duct joins the common bile duct just prior to the ampulla of Vater, after which both ducts perforate the medial side of the second portion of the duodenum at the major duodenal papilla.Gallstone: ), cholelithiasisSociety of American Gastrointestinal and Endoscopic Surgeons: United StatesPercutaneous transhepatic cholangiographyBiliary tract: The biliary tract, (biliary tree or biliary system) refers to the liver, gall bladder and bile ducts, and how they work together to make, store and secrete bile. Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin.Cystic duct: The cystic duct is the short duct that joins the gallbladder to the common bile duct. It usually lies next to the cystic artery.Lumbar lymph trunk: The lumbar trunks are formed by the union of the efferent vessels from the lateral aortic lymph glands.Cholangitis (disambiguation): Cholangitis is any inflammation of the biliary tree, including:Porcelain gallbladderSalivary duct carcinoma: Salivary duct carcinoma, abbreviated SDC, is a rare type of aggressive cancer that arises from the salivary glands.http://www.Liver sinusoid: A liver sinusoid is a type of sinusoidal blood vessel (with fenestrated, discontinuous endothelium) that serves as a location for the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.SIU SOM Histology GIBilin (biochemistry): Bilins, bilanes or bile pigments are biological pigments formed in many organisms as a metabolic product of certain porphyrins. Bilin (also called bilichrome) was named as a bile pigment of mammals, but can also be found in lower vertebrates, invertebrates, as well as red algae, green plants and cyanobacteria.Major duodenal papilla: The major duodenal papilla is an opening of the pancreatic duct into the duodenum. The major duodenal papilla is, in most people, the primary mechanism for the secretion of bile and other enzymes that facilitate digestion.Pneumobilia: Pneumobilia is the presence of gas in the biliary system. Causes include a biliary-enteric anastomosis, an incompetent sphincter of Oddi and spontaneous biliary-enteric fistula.CholangiocarcinomaSphincter of Oddi dysfunctionCholestasisUterine malformationBiliary atresiaTaurocholic acidDrainage system (agriculture): An agricultural drainage system is a system by which the water level on or in the soil is controlled to enhance agricultural crop production.PancreatitisBilirubinSecondary sclerosing cholangitis: Secondary sclerosing cholangitis abbreviated as (SSC) is a disease that is morphologically similar to primary sclerosing cholangitis (PSC) but that originates from a known pathological process. Its clinical and cholangiographic features may mimic PSC, yet its natural history may be more favorable if recognition is prompt and appropriate therapy is introduced.Mike Nevin: Michael D. Nevin (born 1943 – December 1, 2012) was a Democratic politician from the U.CDCa1: CDCa1 is a protein product of the human genome. The gene that codes for this protein is found on chromosome 1, from 150,076,963-150,079,657.JejunostomyJaundiceNasolacrimal duct: The nasolacrimal duct (sometimes called the tear duct) carries tears from the lacrimal sac into the nasal cavity. The opening of the nasolacrimal duct into the inferior nasal meatus is partially covered by a mucosal fold (valve of Hasner or plica lacrimalis).American Association for the Study of Liver Diseases: The American Association for the Study of Liver Diseases (AASLD) is the leading organization of scientists and health care professionals committed to preventing and curing liver disease. AASLD was founded in 1950 by a small group of leading liver specialists (including Hans Popper, Leon Schiff, Fred Hoffbauer, Cecil Watson, Jesse Bollman, and Sheila Sherlock, to name a few) to bring together those who had contributed to the field of hepatology.Sonographic Murphy sign: A Sonographic Murphy sign refers to a finding when performing diagnostic medical sonography. It is different from the Murphy sign found on physical examination, but both signs are associated with cholecystitis When the sonographer presses directly over the gallbladder, and the patient expresses pain, more than when the sonographer presses anywhere else, this is said to be a positive sonographic Murphy sign.Roux: Roux is flour and fat cooked together and used to thicken sauces. The fat is butter in French cuisine, but may be lard or vegetable oil in other cuisines.Ejaculatory duct obstructionExtracorporeal shock wave lithotripsyHepatolithiasis: Hepatolithiasis is the presence of gallstones in the biliary ducts of the liver. Treatment is usually surgical.Cholic acidBiliary injury: Biliary injury (bile duct injury) is the traumatic damage of the bile ducts. It is most commonly an iatrogenic complication of cholecystectomy — surgical removal of gall bladder, but can also be caused by other operations or by major trauma.Lithocholic acidPancreaticoduodenectomyEndoscopy unit: An endoscopy unit refers to a dedicated area where medical procedures are performed with endoscopes, which are cameras used to visualize structures within the body, such as the digestive tract and genitourinary system. Endoscopy units may be located within a hospital, incorporated within other medical care centres, or may be stand-alone in nature.IRGM: Immunity-related GTPase family M protein (IRGM), also known as interferon-inducible protein 1 (IFI1), is an enzyme that in humans is IRGM gene.EndoscopyTaurochenodeoxycholic acidMurphy's sign: In medicine, Murphy's sign refers to a maneuver during a physical examination as part of the abdominal examination and a finding elicited in ultrasonography. It is useful for differentiating pain in the right upper quadrant.Iminodiacetic acidEnterohepatic circulationBalloon catheter: A balloon catheter is a type of "soft" catheter with an inflatable "balloon" at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.Klatskin tumorPancreatic bud: The ventral and dorsal pancreatic buds (or pancreatic diverticula) are outgrowths of the duodenum during human embryogenesis. They join together to form the adult pancreas.Jean Emond: Jean C. Emond is the current Thomas S.Enterolith
