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. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc. All rights reserved.
