CPT® Code 47785

The CPT® Code 47785 refers to the surgical procedure known as Roux-en-Y anastomosis of the intrahepatic biliary ducts and gastrointestinal tract. This complex surgical intervention is primarily aimed at addressing biliary obstruction, which can occur due to various conditions affecting the bile ducts. In simpler terms, this procedure creates a new pathway for bile to flow from the liver into the gastrointestinal tract, bypassing any obstructions that may be present in the bile ducts. The term 'Roux-en-Y' describes the specific configuration of the surgical connection, which resembles the letter 'Y' and involves the use of a segment of the small intestine, typically the jejunum. During the procedure, an abdominal incision is made to access the liver and bile ducts. The surgeon carefully dissects the liver hilum to expose the intrahepatic bile ducts, which are the ducts located within the liver. A segment of the small intestine is mobilized and divided to create a limb that will be connected to the intrahepatic bile ducts. This connection allows bile to drain directly from the liver into the small intestine, facilitating proper digestion and preventing complications associated with bile duct obstructions. The surgical technique requires meticulous attention to detail to ensure that the anastomosis is secure and that the patient can recover effectively post-surgery.
