[Therapeutic strategies in neoplasms of the distal bile duct and the Vater's ampulla].

Malignant periampullary and ampullary tumors represent an anatomic and clinical entity of complex surgical approach due to the difficulty in setting out an early diagnosis, for the back of symptoms at early stages. The Authors at the Department of Surgery and Medical Technology Applications "F. Durante", University of Rome "La Sapienza", since 1990 to 2001 observed 19 cases. The results of surgical treatment of these tumors are here reported. By the analysis of the cases it is evident that long-term survival if mainly conditioned by prompt diagnosis stage of the tumor, and patient status before the operation.
