CPT® Code 47760

An anastomosis of extrahepatic biliary ducts and the gastrointestinal tract, designated by CPT® Code 47760, is a surgical procedure aimed at creating a connection between the bile ducts outside the liver and the digestive system. 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 such as tumors, gallstones, or strictures that impede the normal flow of bile. During the procedure, an abdominal incision is made along the midline to access the liver, gallbladder, and a segment of the small intestine or stomach. The obstructed bile duct is carefully divided above the site of obstruction, and the ends are sutured closed to prevent bile leakage. Subsequently, a segment of the stomach or small intestine, typically the jejunum, is mobilized and positioned adjacent to the bile duct. The bile duct is then incised longitudinally, and an anastomosis is created by connecting the bile duct to the stomach or small intestine. This surgical connection facilitates the direct drainage of bile from the bile duct into the small intestine, thereby alleviating the obstruction and restoring normal digestive function. After the anastomosis is completed, the surgical site is irrigated, and drains may be placed as necessary before the abdominal incision is closed in layers to promote proper healing.
