Application of multiple Roux-en-Y hepaticojejunostomy reconstruction by formation of bile hilar duct lake in the operation of hilar cholangiocarcinoma.

BACKGROUND

Hilar cholangiocarcinoma is the most common malignant tumor of the extrahepatic bile duct. Until now, radical resection has been the most effective method for the long-term survival of patients with the disease. However, many problems have emerged in the field of hepatobiliary surgery for a long time, including complex surgical procedures, low resection rate, and postoperative complications. We have adopted the "multiple Roux-en-Y hepaticojejunostomy reconstruction by formation of a bile duct lake" technique in the treatment of hilar cholangiocarcinoma since 2008, and obtained satisfactory short- and long-term results.

AIM

To examine the feasibility of the application of multiple Roux-en-Y hepaticojejunostomy reconstruction by formation of a bile duct lake in the operation of hilar cholangiocarcinoma.

METHODS

A retrospective analysis was performed for the clinical data, surgical methods, and results of 76 patients with hilar cholangiocarcinoma who were treated with hilar bile duct lake-forming multiple Roux-en-Y hepaticojejunostomy reconstruction at Gansu Provincial Hospital.

RESULTS

In all 76 cases, the operation was successful and no operative death occurred. The mean (range) operation time was 215.4 ± 53.5 min (124-678 min), and the amount of bleeding during the operation was 428.2 ± 63.8 mL (240-2200 mL). The overall 1-year survival rate was 78.9%, and the 3-year survival rate was 32.8%.

CONCLUSION

The multiple Roux-en-Y hepaticojejunostomy reconstruction technique with formation of a bile duct lake is safe and effective for the surgical treatment of hilar cholangiocarcinoma.
