Biliary Tract Neoplasms
Respiratory Tract Neoplasms
Respiratory Tract Neoplasms are defined as abnormal growths or tumors that develop within the respiratory system, including the nose, sinuses, throat (pharynx), voice box (larynx), windpipe (trachea), bronchi, and lungs, which can be benign or malignant, with the potential to cause significant morbidity and mortality.
Biliary Tract Diseases
Biliary Tract
Biliary Tract Surgical Procedures
Any surgical procedure performed on the biliary tract.
Gallbladder Neoplasms
Tumors or cancer of the gallbladder.
Cholangiocarcinoma
A malignant tumor arising from the epithelium of the BILE DUCTS.
Bile Duct Neoplasms
Tumors or cancer of the BILE DUCTS.
Bile Ducts, Extrahepatic
Passages external to the liver for the conveyance of bile. These include the COMMON BILE DUCT and the common hepatic duct (HEPATIC DUCT, COMMON).
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.
Cholelithiasis
Presence or formation of GALLSTONES in the BILIARY TRACT, usually in the gallbladder (CHOLECYSTOLITHIASIS) or the common bile duct (CHOLEDOCHOLITHIASIS).
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.
Cholecystectomy
Surgical removal of the GALLBLADDER.
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.
Choledochostomy
Common Bile Duct
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.
Pancreatic Neoplasms
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
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).
Cholangiopancreatography, Endoscopic Retrograde
Biliary Fistula
Abnormal passage in any organ of the biliary tract or between biliary organs and other organs.
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.
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.
Cholestasis, Extrahepatic
Impairment of bile flow in the large BILE DUCTS by mechanical obstruction or stricture due to benign or malignant processes.
Hepatic Duct, Common
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.
Choledochal Cyst
Deoxycytidine
Gallbladder Diseases
Diseases of the GALLBLADDER. They generally involve the impairment of BILE flow, GALLSTONES in the BILIARY TRACT, infections, neoplasms, or other diseases.
Neoplasms
Urinary Tract Infections
Inflammatory responses of the epithelium of the URINARY TRACT to microbial invasions. They are often bacterial infections with associated BACTERIURIA and PYURIA.
CA-19-9 Antigen
Jaundice
A clinical manifestation of HYPERBILIRUBINEMIA, characterized by the yellowish staining of the SKIN; MUCOUS MEMBRANE; and SCLERA. Clinical jaundice usually is a sign of LIVER dysfunction.
Neoplasms, Cystic, Mucinous, and Serous
Carcinoma
Mammaglobin B
Jejunostomy
Common Bile Duct Diseases
Gastrointestinal Tract
Generally refers to the digestive structures stretching from the MOUTH to ANUS, but does not include the accessory glandular organs (LIVER; BILIARY TRACT; PANCREAS).
Cystic Duct
The duct that is connected to the GALLBLADDER and allows the emptying of bile into the COMMON BILE DUCT.
