Biliary Tract Surgical Procedures
Any surgical procedure performed on the biliary tract.
Biliary Tract Neoplasms
Biliary Tract Diseases
Biliary Tract
Gallbladder Neoplasms
Tumors or cancer of the gallbladder.
Surgical Procedures, Operative
Cholangiocarcinoma
A malignant tumor arising from the epithelium of the BILE DUCTS.
Gallstones
Solid crystalline precipitates in the BILIARY TRACT, usually formed in the GALLBLADDER, resulting in the condition of CHOLELITHIASIS. Gallstones, derived from the BILE, consist mainly of calcium, cholesterol, or bilirubin.
Bile Duct Neoplasms
Tumors or cancer of the BILE DUCTS.
Cholelithiasis
Presence or formation of GALLSTONES in the BILIARY TRACT, usually in the gallbladder (CHOLECYSTOLITHIASIS) or the common bile duct (CHOLEDOCHOLITHIASIS).
Bile Ducts, Extrahepatic
Cholecystectomy
Surgical removal of the GALLBLADDER.
Bile Ducts, Intrahepatic
Passages within the liver for the conveyance of bile. Includes right and left hepatic ducts even though these may join outside the liver to form the common hepatic duct.
Cholangitis
Inflammation of the biliary ductal system (BILE DUCTS); intrahepatic, extrahepatic, or both.
Gallbladder
A storage reservoir for BILE secretion. Gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the CYSTIC DUCT to the DUODENUM, for degradation of dietary lipid.
Ampulla of Vater
Bile Ducts
The channels that collect and transport the bile secretion from the BILE CANALICULI, the smallest branch of the BILIARY TRACT in the LIVER, through the bile ductules, the bile ducts out the liver, and to the GALLBLADDER for storage.
Postoperative Complications
Treatment Outcome
Common Bile Duct
The largest bile duct. It is formed by the junction of the CYSTIC DUCT and the COMMON HEPATIC DUCT.
Choledochostomy
Bile
An emulsifying agent produced in the LIVER and secreted into the DUODENUM. Its composition includes BILE ACIDS AND SALTS; CHOLESTEROL; and ELECTROLYTES. It aids DIGESTION of fats in the duodenum.
Cholecystitis
Inflammation of the GALLBLADDER; generally caused by impairment of BILE flow, GALLSTONES in the BILIARY TRACT, infections, or other diseases.
Cholestasis
Impairment of bile flow due to obstruction in small bile ducts (INTRAHEPATIC CHOLESTASIS) or obstruction in large bile ducts (EXTRAHEPATIC CHOLESTASIS).
Retrospective Studies
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Cholangiopancreatography, Endoscopic Retrograde
Cholangiography
An imaging test of the BILIARY TRACT in which a contrast dye (RADIOPAQUE MEDIA) is injected into the BILE DUCT and x-ray pictures are taken.
Biliary Fistula
Abnormal passage in any organ of the biliary tract or between biliary organs and other organs.
Surgical Procedures, Minor
Bile Duct Diseases
Diseases in any part of the ductal system of the BILIARY TRACT from the smallest BILE CANALICULI to the largest COMMON BILE DUCT.
