CPT® Code 47765

An anastomosis of intrahepatic ducts and the gastrointestinal tract, represented by CPT® Code 47765, is a surgical procedure aimed at creating a connection between the intrahepatic bile ducts and the gastrointestinal tract. This procedure is commonly referred to as a biliary bypass and is primarily indicated for the treatment of biliary obstruction, which can occur due to various conditions affecting the bile ducts. The procedure involves making an abdominal incision to access the liver, gallbladder, and a segment of the small intestine or stomach. During the operation, the obstructed bile duct is carefully divided above the site of obstruction, and the ends are sutured closed to prevent leakage. Subsequently, a segment of the gastrointestinal tract, typically the jejunum or stomach, is mobilized and brought into proximity with the bile duct. The bile duct is then incised longitudinally, allowing for the anastomosis to occur. This connection facilitates the direct drainage of bile from the intrahepatic bile ducts into the small intestine, thereby alleviating the obstruction and restoring normal bile flow. The surgical site is irrigated, and drains may be placed as necessary before the abdominal incision is closed in layers to promote proper healing.
