[Malignant tumors of the Vater's ampulla. Presentation of 28 cases and review of the literature]. / Tumores malignos de la ampolla de Vater. Presentación de 28 cases y revisión de la literatura.

We present a study of 28 patients, treated for adenocarcinoma of Vater's ampulla. We emphasize the distinct behavior of each one of the peri-ampullar tumors, those which affect Vater's ampulla yielding the best prognosis. We gathered data regarding gender, age, clinical manifestations, and analytical data. The confirmatory diagnosis gives us 100% of CPRE cases. All of the patients were submitted to surgical treatment with anatomic pathological confirmation of the diagnosis, be it pre or postoperative. We practiced curative surgery in 57.2% of the cases and palliative in 42.8% of the cases. We observed postoperative complications in 17.8% of the patients and peroperative mortality in 3.5%. Actual survival of the series of patients for whom exeretic surgery was performed is significantly superior to that of the other patients.
