CPT® Code 47720

A cholecystoenterostomy, commonly known as a biliary bypass procedure, is a surgical intervention aimed at addressing biliary obstruction. This procedure is particularly relevant when there is a need to create a direct connection between the gallbladder and the small intestine, allowing for the drainage of bile. In the context of CPT® Code 47720, a direct choledochoenterostomy is specifically performed. The surgical approach begins with a midline abdominal incision, which provides access to the gallbladder and a segment of the small intestine. During the procedure, the gallbladder is carefully dissected, and a segment of the small intestine is mobilized and rotated to align with the gallbladder. A longitudinal incision is made in the small intestine, facilitating the anastomosis, or surgical connection, between the gallbladder and the small intestine. This connection is crucial as it enables bile to flow directly from the gallbladder into the small intestine, thereby bypassing any obstructions that may be present in the biliary tract. This procedure is essential for patients suffering from conditions that impede normal bile flow, ensuring that digestive processes can continue effectively.
