The surgical treatment of adenocarcinoma of the duodenum distal to the ampulla of Vater.
The case analysis of five patients with post-ampullary adenocarcinoma of the duodenum showed this to be a tumor which favors local extension into surrounding organs, instead of lymphatic or hepatic metastasis. This justifies and aggressive resectional approach to treatment, pancreaticoduodenectomy being the basic operation to be applied. Proximity to the superior mesenteric vessels involving them in four out of five of our tumors, is the major anatomic limiting factor. Leaving vascular control for the end of the excision and perfusing them to maintain viability of the gut until a comfortable vascular anastomosis can be constructed, should solve the problem. Misdiagnosis proved to be a prominent source of error, causing delays and inappropriate therapy. The Cancer Registry of Puerto Rico has documented an incidence of carcinoma of the duodenum similar to that of the ampulla of Vater. This fact demands the same care in the conduct of diagnostic procedures of the distal duodenum as is customary in the visualization of the ampulla.
