Safety and efficacy of hepaticoduodenostomy for biliary reconstruction after extrahepatic mid-bile duct cancer surgery

초록

Background: Bile duct resection and reconstruction for bile duct cancer (BDC) is a complex surgical and oncologic procedure that requires extensive resection and reconstruction of the biliary tract. Hepaticojejunostomy is commonly performed for biliary reconstruction after extrahepatic mid-bile duct resection, while hepaticoduodenostomy (HD) is performed only rarely due to the risk of ascending cholangitis. However, the efficacy of HD has not been well-established in extrahepatic mid-BDC surgery. In this study, we aimed to analyze the outcomes of HD in patients who underwent bile duct resection for extrahepatic mid-BDC. Methods: We retrospectively analyzed 38 extrahepatic mid-BDC patients who underwent bile duct resection in our center between January 2018 and June 2023. We compared postoperative outcomes, cancer recurrence, and patient survival between hepaticojejunostomy (n=20) and HD (n=18) groups. Results: Operation time for the HD group was significantly shorter than that of the hepaticojejunostomy group (188 vs. 206 min, P=0.044) with no significant differences in postoperative outcomes. Regression analysis showed that a HD was not associated with a significantly high risk of cancer recurrence or decrease in patient survival. Conclusions: HD appears to have comparable operative benefits, postoperative complications, and oncologic outcomes to hepaticojejunostomy in extrahepatic mid-BDC patients.
