[A case of primary carcinoma of the duodenum with subampullar localization].

The authors illustrate a case of previous duodenal adenocarcinoma with subvaterian localization and, after revising the literature and some general remarks, they explain their practice. They come to the conclusion that in some well selected cases, duodenal segmental resection can be correctly applied. They remember that the most important factor of the improvement of the prognosis is early diagnosis: it is indispensable for radical exerectical therapy.
