title: Villous tumors of the ampulla of Vater: local resection versus pancreatoduodenectomy.
abstract: Villous adenomas involving the ampulla of Vater are uncommon. In particular, malignant potential of villous tumors may be difficult to determine preoperatively. In such cases, the decision to perform a conservative local excision or the more radical pancreatoduodenectomy should be based on accurate histologic assessment and the possibility of obtaining adequate margins of resection.
