Surgical Ampullectomy with Complete Resection of the Common Bile Duct: a New Procedure for Radical Resection of Non-invasive Ampulloma with Biliary Extension.

Extension of ampulloma into the lower common bile duct (CBD) is observed in up to 30% of cases. This biliary extension can prevent complete tumor resection thus is considered as a contraindication for endoscopic and even surgical ampullectomy. For ampullomas associated with a prolonged biliary extension, a pancreaticoduodenectomy is associated with a high morbidity and can be considered as an overtreatment for a benign neoplasm. The present study describes a new surgical approach including ampullectomy with complete resection of the intrapancreatic CBD and restoration of both biliary and pancreatic flow by two separate anastomoses. This procedure was performed in seven patients for a non-invasive ampulloma with a 25- to 70-mm CBD involvement. No patients died and three developed postoperative complications. Resection was R0 in all patients but one. With a 24-month median follow-up (range = 3-84), no patients developed pancreatic insufficiency or tumor recurrence.
