Extraction of choledocholithiasis and/or intrahepatic stones: choledocholithiasis is the presence of gallstones within the common bile duct. They can be either primary (formed within the duct) or secondary (entering the duct from the gallbladder). Biliary endoscopic sphincterotomy allows for opening of the sphincter of Oddi, allowing stones to ...
This causes a backup of fluid that can travel up both the bile duct and the pancreatic duct. Gallbladder stones can lead to obstruction of the biliary tree via which gallbladder and pancreas enzymes are secreted into the duodenum, causing emergency events such as acute cholecystitis or acute pancreatitis. [12]
Cholecystectomy with a choledochoplasty is the most frequent treatment of primary fistulas, whereas the bile duct drainage or the endoscopic stenting is the best choice in case of minor iatrogenic bile duct injuries. [3]
Bile from the gallbladder is carried to the CBD and emptied into the duodenum. CBD drainage might be obstructed due to distal CBD stricture, which is narrowing of the CBD due to the presence of scar tissue within the duct, and choledocholithiasis, the presence of gallstones. Obstruction can occur when gallstones may be too large to pass through ...
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.
Self-expandable metallic stents "play an important role in the management of malignant obstructing lesions in the gastrointestinal tract." [2] A stent may be inserted into the common bile duct during an endoscopic retrograde cholangiopancreatography, especially if gallstone removal is deemed too risky. [3]
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.
Jaundice is commonly caused by conditions such as pancreatic cancer, which causes blockage of the bile duct passing through the cancerous portion of the pancreas; cholangiocarcinoma, cancer of the bile ducts; blockage by a stone in patients with gallstones; and from scarring after injury to the bile duct during gallbladder removal.
