title: Local resection of biliopancreatic cancer.
abstract: Biliopancreatic tumors that are potentially amenable to local resection include proximal bile duct tumors (Klatskin tumors), mid-choledochal duct tumors and tumors arising from the papilla of Vater. This paper reviews our experience in the AMC, with local resection of these conditions. From 1983-1997, 112 patients underwent surgical resection of a carcinoma of the hepatic duct confluence (Klatskin tumor). Local resection was undertaken in 80 patients (52 patients with type I and II tumors, and 28 patients with type III tumors) whereas in 32 patients with type III tumors, hilar resection was performed with liver resection. Negative surgical margins were achieved in 10 patients after local resection of type I and II tumors (19.2%), in 1 patient after local resection of a type III tumor (3.6%), and in 5 patients after hilar resection and liver resection (15.6%). Middle-third carcinomas of the extra-hepatic biliary tract are less common than proximal or distal bile duct tumors. From 1993-1998, 12 patients underwent resection of a mid-choledochal duct carcinoma. In 8 patients, local resection was performed and in 4 patients, subtotal pancreatoduodenectomy (PPPD) because of the close relationship of the tumor and the pancreas. Four patients had negative surgical margins, 2 after local resection (25%) and 2 after PPPD (50%). Although accepted for villous adenomas located in the ampulla, local resection for ampullary carcinoma is controversial. Nine patients underwent local resection of a presumed adenoma that proved to be an ampullary carcinoma. In 4 patients with T1 tumors, resection of the carcinoma was locally complete (44%). Additional PPPD was performed in 6 patients, including the 4 patients with complete local resections, showing no residual tumor at the previous site of excision, but, lymphnode metastases in two resection specimens (both of patients with presumed T1 tumors). Hence, local resection of a T1 ampullary carcinoma might result in tumor free margins, but does not deal with (usually retropancreatic) lymphnode metastases. In conclusion, local resection is applicable to Klatskin type I and II tumors. Local resection may be considered in the proximally located, mid-choledochal duct carcinomas but, when located closer to the pancreas, PPPD is the preferred treatment. For ampullary adenomas, local resection is feasible unless frozen section examination raises suspicion on a malignancy. Local resection of even limited ampullary carcinomas is not advisable because of lymphatic dissemination of the tumor and consequently, inadequate clearance.
