Radical Resection Outperforms Preservation in Congenital Bile Duct Surgery

In a comprehensive multicenter trial involving 355 patients with type I congenital bile duct dilation, radical extrahepatic cyst excision, compared to subtotal excision, markedly improved long-term outcomes. The radical approach significantly reduced rates of recurrent cholangitis, pancreatitis, and readmission, leading to better quality of life metrics and lower carcinogenesis risk. Both techniques showed similar perioperative complications, establishing radical resection as the superior choice for patients with intrapancreatic bile duct involvement.
