Cholecystostomy or (cholecystotomy) is a medical procedure used to drain the gallbladder through either a percutaneous or endoscopic approach. The procedure involves creating a stoma in the gallbladder, which can facilitate placement of a tube or stent for drainage, first performed by American surgeon, Dr. John Stough Bobbs, in 1867.
Other procedures associated with ERCP include the trawling of the common bile duct with a basket or balloon to remove gallstones and the insertion of a plastic stent to assist the drainage of bile. [11] Also, the pancreatic duct can be cannulated and stents be inserted. The pancreatic duct requires visualisation in cases of pancreatitis.
Endoscopic image of a biliary stent seen protruding from the ampulla of Vater at the time of duodenoscopy. Pancreatic and biliary stents provide pancreatic and bile drainage from the gallbladder, pancreas, and bile ducts to the duodenum in conditions such as ascending cholangitis due to obstructing gallstones. Pancreatic and biliary stents can ...

They are usually inserted when a disease process has led to narrowing or obstruction of the organ in question, such as the esophagus or the colon .
Fluoroscopic image of self-expandable metallic stent in the esophagus. The black solid structure is the endoscope used to place the stent. Self-expandable metallic stents are typically inserted at the time of endoscopy, usually with assistance with fluoroscopy or x-ray images taken to guide placement. Prior to the development of SEMS small ...
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 biliary tree is normally relatively free of bacteria because of certain protective mechanisms. The sphincter of Oddi acts as a mechanical barrier. The biliary system normally has low pressure (8 to 12 cmH 2 O) [9] and allows bile to flow freely through. The continuous forward flow of the bile in the duct flushes bacteria, if present, into ...
