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.
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 ...
Hypaque or other water-soluble dye may be placed through the passage to ensure patency of the stent on fluoroscopy. [15] Enteric and colonic SEMS are inserted in a similar fashion, but in the duodenum and colon respectively. [16] Biliary SEMS are used to palliatively treat tumours of the pancreas or bile duct that obstruct the common bile duct.
Biliary stents are often used during endoscopic retrograde cholangiopancreatography (ERCP) to treat blockages that narrow your bile or pancreatic ducts. In cases of malignant biliary obstruction, endoscopic stent placement is one of the treatment options to relieve the obstruction. Biliary drainage is considered effective, particularly in bile ...
An accessory bile duct is a conduit that transports bile and is considered to be supernumerary or auxiliary to the biliary tree. [ 1 ] It may be described by its location relative to the gallbladder as supravesicular [ 2 ] [ 3 ] (superior to the gallbladder body) or subvesicular [ 4 ] [ 5 ] (inferior to the gallbladder body).
Performing an anastomosis alters the structural composition of bile ducts, which can result in bile stricture obstruction. [19] It leads to slowing of the biliary flow and dilation of the CBD, causing more progressive symptoms of jaundice. [6] An anastomotic stricture is more likely to occur if the choledoctomy incision was less than 2 cm in ...
