U-tube hepaticoenterostomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 47802 refers to a U-tube hepaticoenterostomy, which is a surgical intervention performed to create a connection between the liver and the small intestine. This procedure is typically indicated in cases where there is a need to bypass obstructed bile ducts or to facilitate bile drainage from the liver directly into the intestine. The operation begins with a midline abdominal incision, allowing access to the liver, gallbladder, and bile ducts. During the surgery, the hilum of the liver is carefully dissected to expose the intrahepatic bile duct, where a U-tube is inserted. This U-tube serves as a conduit for bile, with one end placed within the bile duct and the other end extending into the small intestine, often through a jejunal Roux-en-Y limb. The procedure involves creating a separate enterotomy, which is an incision into the intestine, to allow the U-tube to exit the intestinal tract. Finally, stab incisions are made in the abdominal wall to secure both ends of the U-tube, ensuring that the system remains stable and functional post-operatively. This detailed approach is crucial for effective bile drainage and management of biliary obstructions.

1. Indications

The U-tube hepaticoenterostomy procedure is indicated for specific clinical scenarios where bile drainage is compromised. The following conditions may warrant this surgical intervention:

  • Obstructed Bile Ducts - This procedure is often performed in cases where there is a blockage in the bile ducts, preventing normal bile flow from the liver to the intestine.
  • Biliary Atresia - A congenital condition where the bile ducts are absent or damaged, necessitating alternative drainage methods.
  • Cholangiocarcinoma - A type of cancer that affects the bile ducts, which may require diversion of bile flow to manage symptoms and improve quality of life.
  • Postoperative Complications - Situations arising from previous surgeries that may have led to strictures or other complications affecting bile drainage.

2. Procedure

The U-tube hepaticoenterostomy involves several critical procedural steps to ensure successful implementation. The following outlines the detailed steps of the procedure:

  • Step 1: Abdominal Incision - The procedure begins with a midline abdominal incision, which provides the surgeon with access to the abdominal cavity, specifically targeting the liver, gallbladder, and bile ducts.
  • Step 2: Exposure of the Liver and Bile Ducts - Once the incision is made, the liver, gallbladder, and bile ducts are carefully exposed to allow for further dissection and manipulation.
  • Step 3: Dissection of the Hilum - The hilum of the liver is dissected to access the intrahepatic bile duct, which is crucial for the placement of the U-tube.
  • Step 4: Placement of the U-tube - The U-tube is inserted into the proximal aspect of the intrahepatic bile duct, ensuring that it is positioned correctly to facilitate bile drainage.
  • Step 5: Threading the U-tube - One end of the U-tube is threaded through the liver and directed into the small intestine, typically into a jejunal Roux-en-Y limb, which is a surgical connection that allows for bile to enter the intestine.
  • Step 6: Enterotomy - A separate enterotomy is performed in the intestine to allow the U-tube to exit the intestinal tract, ensuring that bile can flow into the digestive system.
  • Step 7: Securing the U-tube - Stab incisions are made in the abdominal wall, through which both ends of the U-tube are brought out and secured to the abdominal wall, providing stability and preventing dislodgment.

3. Post-Procedure

After the U-tube hepaticoenterostomy procedure, patients typically require careful monitoring and management to ensure proper recovery. Post-operative care may include monitoring for signs of infection, ensuring that the U-tube remains patent, and managing any potential complications related to bile drainage. Patients may also need to follow specific dietary guidelines and may be advised on the care of the U-tube to prevent dislodgment or blockage. Follow-up appointments are essential to assess the function of the U-tube and the overall health of the patient.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
