Villous tumors of the ampulla Vater.

Patients with villous tumors of the ampulla Vater usually present with jaundice, intermittent or constant, but may seek care for abdominal pain, intestinal hemorrhage, or pancreatitis. Because villous tumors may harbor carcinoma in 30 to 50 per cent of cases, appropriate management may require radical resection. We have managed four patients with villous lesions of the ampulla Vater occurring in 1981, 1992, 1993, and 1995. Three were villous (two with malignant change) and one was a villoglandular adenoma. Treatment consisted of local excision with reimplantation of the ducts in one patient, Whipple resection in two patients, and biliopancreatic bypass in one who had distant nodal metastases not resectable for cure. This patient died 18 months after operation of an unrelated disease, but the others were well at last follow-up. The presentation as well as the diagnostic and therapeutic considerations in the management of villous tumors of the ampulla Vater are discussed.
