Biliary drainage is performed with a tube or catheter (called a biliary drain, biliary stent or biliary catheter) by a surgeon or, commonly, an interventional radiologist. [3] It can be used to relieve a blockage in the bile duct, either permanently or as a temporary solution before definite treatment such as surgery.
Type IVb: Multiple dilatations involving only the extrahepatic bile ducts. Type V: Cystic dilatation of intrahepatic biliary ducts without extrahepatic duct disease. The presence of multiple saccular or cystic dilations of the intrahepatic ducts is known as Caroli's disease. [4] Type VI: An isolated cyst of the cystic duct is an extremely rare ...
Intrahepatic bile ducts compose the outflow system of exocrine bile product from the liver. They can be divided into: [2] Lobar ducts (right and left hepatic ducts) - stratified columnar epithelium. Interlobar ducts (between the main hepatic ducts and the interlobular ducts) - pseudostratified columnar epithelium.
Although CT, ultrasound, and MRI may help differentiate intrahepatic and extrahepatic cholestasis, the cause and extent of obstruction is best determined by cholangiography. [77] Potential causes of extrahepatic cholestasis include obstructions outside the wall of the lumen, those outside the duct, and obstructions found in the duct lumen. [ 77 ]
Biliary fistulas are abnormal communications between organs and the biliary tract. [3] Once diagnosed, they usually require drainage. The term "biloma" was first coined in 1979 by Gould and Patel. [4] [5] They discovered it in a case with extrahepatic bile leakage. The cause of this was trauma to the upper right quadrant of the abdomen ...
The bile duct [1] [4] (formerly known as the common bile duct [4]) is a part of the biliary tract. [4] It is formed by the union of the common hepatic duct and cystic duct. It ends by uniting with the pancreatic duct to form the hepatopancreatic ampulla. It possesses its sphincter to enable the regulation of bile flow.
Cholangiocarcinoma, also known as bile duct cancer, is a type of cancer that forms in the bile ducts. [2] Symptoms of cholangiocarcinoma may include abdominal pain , yellowish skin , weight loss , generalized itching , and fever. [ 1 ]
The purpose of biliary endoscopic sphincterotomy in the treatment of a bile leak is to reduce or eliminate the pressure gradient between the bile duct and the duodenum, encouraging transpapillary bile flow and allowing the leak to heal. [7] Others: Palliation of malignant biliary strictures; Gallbladder drainage; Biliary parasite removal; Sump ...
