title: [Tumors of the ampulla of Vater--local or radical resection?].
abstract: Duodenal ampulla is a complex anatomical and histological site and a tumor may arise from one of three types of epithelium: duodenal mucosa, pancreatic duct and distal common bile duct. Neoplasia from each of these locations may exhibit different growth models and though it is difficult to establish their origin before operation, surgical treatment for all resectable tumors is essentially alike. The outcome of these tumors is vitally influenced by the type of epithelium from which they derive. Benign adenomas appear to be a frequent precursor of carcinoma of the ampulla of Vater, therefore, a local resection can lead to an under treated early cancer which would have benefited from a radical excision, with a much better long term result. We consider acceptable to perform an ampullectomy whenever is possible to safely state the benignity of the tumor or when a major procedure is hazardous.
