A congenital anatomic malformation of a bile duct, including cystic dilatation of the extrahepatic bile duct or the large intrahepatic bile duct. Classification is based on the site and type of dilatation. Type I is most common.

Surgical formation of an opening through the ABDOMINAL WALL into the JEJUNUM, usually for enteral hyperalimentation.

Any fluid-filled closed cavity or sac that is lined by an EPITHELIUM. Cysts can be of normal, abnormal, non-neoplastic, or neoplastic tissues.

Diseases of the COMMON BILE DUCT including the AMPULLA OF VATER and the SPHINCTER OF ODDI.

Non-invasive diagnostic technique for visualizing the PANCREATIC DUCTS and BILE DUCTS without the use of injected CONTRAST MEDIA or x-ray. MRI scans provide excellent sensitivity for duct dilatation, biliary stricture, and intraductal abnormalities.

A Y-shaped surgical anastomosis of any part of the digestive system which includes the small intestine as the eventual drainage site.

The largest bile duct. It is formed by the junction of the CYSTIC DUCT and the COMMON HEPATIC DUCT.

Predominantly extrahepatic bile duct which is formed by the junction of the right and left hepatic ducts, which are predominantly intrahepatic, and, in turn, joins the cystic duct to form the common bile duct.

Any surgical procedure performed on the biliary tract.

Surgical formation of an opening into the DUODENUM.

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.

Imino acids are organic compounds containing a nitrogen atom in their structure, classified as derivatives of amino acids, where the carbon atom adjacent to the carboxyl group is bonded to a nitrogen atom instead of a hydrogen atom, forming a characteristic imino functional group.

Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.

Passages external to the liver for the conveyance of bile. These include the COMMON BILE DUCT and the common hepatic duct (HEPATIC DUCT, COMMON).

Progressive destruction or the absence of all or part of the extrahepatic BILE DUCTS, resulting in the complete obstruction of BILE flow. Usually, biliary atresia is found in infants and accounts for one third of the neonatal cholestatic JAUNDICE.

A benign neoplasm of muscle (usually smooth muscle) with glandular elements. It occurs most frequently in the uterus and uterine ligaments. (Stedman, 25th ed)

The condition of an anatomical structure's being dilated beyond normal dimensions.

Ducts that collect PANCREATIC JUICE from the PANCREAS and supply it to the DUODENUM.

Liquid material found in epithelial-lined closed cavities or sacs.

Diseases in any part of the BILIARY TRACT including the BILE DUCTS and the GALLBLADDER.

The BILE DUCTS and the GALLBLADDER.

Pathological processes of the PANCREAS.

Lymphangitis is a medical condition characterized by the inflammation and infection of the lymphatic vessels, often presenting as red, tender streaks along the path of the affected lymphatic channel.

A radiopharmaceutical used extensively in cholescintigraphy for the evaluation of hepatobiliary diseases. (From Int Jrnl Rad Appl Inst 1992;43(9):1061-4)

Abnormal passage in any organ of the biliary tract or between biliary organs and other organs.

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.

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.

Operation for biliary atresia by anastomosis of the bile ducts into the jejunum or duodenum.

Creation of an artificial external opening or fistula in the intestines.

General term for CYSTS and cystic diseases of the OVARY.

Tumor or cancer of the COMMON BILE DUCT including the AMPULLA OF VATER and the SPHINCTER OF ODDI.

Tumors or cancer of the BILE DUCTS.

Intradermal or subcutaneous saclike structure, the wall of which is stratified epithelium containing keratohyalin granules.

Surgical anastomosis of the pancreatic duct, or the divided end of the transected pancreas, with the jejunum. (Dorland, 28th ed)

INFLAMMATION of the PANCREAS that is characterized by recurring or persistent ABDOMINAL PAIN with or without STEATORRHEA or DIABETES MELLITUS. It is characterized by the irregular destruction of the pancreatic parenchyma which may be focal, segmental, or diffuse.

The fluid containing digestive enzymes secreted by the pancreas in response to food in the duodenum.

Tumors or cancer in the BILIARY TRACT including the BILE DUCTS and the GALLBLADDER.

Tear or break of an organ, vessel or other soft part of the body, occurring in the absence of external force.

Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
