    Abstract:
    BACKGROUND: This study aimed to reveal the early and late postoperative complications and outcomes after surgery for congenital biliary dilatation (CBD) by reviewing cases over the past 40 years. METHODS: We retrospectively evaluated 59 patients with CBD who underwent radical surgery for complications and outcomes, based on medical records. Early complications were defined as those requiring treatment within 5 years of the initial operation. Late complications were defined as those treated more than 5 years later. RESULTS: The median age at the first surgery was 37 months. Regarding biliary reconstruction, 54 of the 59 patients (91.5%) underwent hepaticojejunostomy. Although three patients underwent cholecystoduodenostomy and one patient underwent hepaticoduodenostomy, all were converted to hepaticojejunostomy after a median of 12.5 years. One patient developed synchronous biliary carcinoma and underwent pancreaticoduodenectomy. Early complications occurred in seven patients with 10 events (surgical site infection, n = 3 bile leakage, n = 3; ileus, n = 3; bile duct obstruction, n = 1 and intussusception, n = 1). Late complications occurred in nine patients with 12 events (ileus, n = 3; anastomotic stricture, n = 3; hepatolithiasis, n = 3; asynchronous biliary carcinoma, n = 2; pancreatolithiasis, n = 1). Two of the three patients with hepatolithiasis underwent hepatectomy refractory to the endoscopic approach. Two patients developed asynchronous biliary carcinoma at 34 and 13 years after last operation; both ultimately died of the carcinoma. Only 35 patients (61.4%) underwent a follow-up examination. A total of 11 female patients (45.8%) eventually married, and all successfully gave birth. CONCLUSION: Although the long-term prognosis is excellent with complete cyst excision and hepaticojejunostomy, we emphasize the importance of long-term follow-up.
