[Transduodenal ampullectomy: an useful alternative for the treatment of Vater's ampulla lesions. Case reports of an unfrecuent surgical technique].

The Vater's ampulla neoplasias are not very frequent lesions. The ampullectomy consists on the total resection of the Vater's ampulla and part of the duodenal wall with the later reconstruction and anastomosis of the common bile duct and the Wirsung's duct to the duodenum. The local resection of the ampulla is an alternative to the duodenopancreatectomy that has to be taken into account, especially in benign lesions as in the case of adenomas of the Vater's ampulla.
