Better long-term outcomes with hilar ductoplasty and a side-to-side Roux-en-Y hepaticojejunostomy.

Abstract Background Whether a wide hilar hepaticojejunostomy after bile duct cyst (BDC) excision can prevent the development of postoperative complications remains an unanswered question. We compared our outcomes after a minimum of 2-y follow-up in patients with Todani type Ia choledochal cyst treated with hilar ductoplasty followed by a side-to-side Roux-en-Y hepaticojejunostomy (ductoplasty group) or radical cyst resection with an end-to-side Roux-en-Y hepaticojejunostomy (conventional group). Methods We retrospectively reviewed the records of patients with Todani type Ia choledochal cyst who received radical cyst excision from January 1997 to December 2012, and we compared the groups' postoperative complications and surgical outcomes. Results The groups' baseline demographics were similar, except for age. The gender distribution and preoperative presenting symptoms were comparable in the ductoplasty ( n  = 72) and conventional ( n  = 53) groups (all P  > 0.05). Average age was 37.0 y for the ductoplasty group and 41.8 y for the conventional group ( P  = 0.024). The short-term complication rate of the groups was not significantly different (conventional group, 13.2% [7/53]; ductoplasty group, 8.3% [6/72]; all P  > 0.05). A significant between-group difference was found in the long-term complication rate of biliary-enteric anastomotic strictures (9.4% in the conventional group and 0% in the ductoplasty group, P  = 0.012). The rates of satisfactory surgical outcomes were 91.1% and 77.1% in the ductoplasty and conventional groups, respectively ( P  = 0.036). Conclusions The application of hilar ductoplasty with a side-to-side Roux-en-Y hepaticojejunostomy as the primary surgery for bile duct cyst excision significantly reduced the postoperative complication of biliary-enteric anastomotic stricture and greatly improved our patients' prognosis with regard to biliary function.
