[Complications of primary malignant tumors of the small intestine]

6 cases of small bowel adenocarcinomata are described. In 5 cases out of 6 the diagnosis was only possible at the moment of operation, which became necessary for the complications of the tumour. Five patients were urgently operated on for intestinal obstruction, and one for peritonitis. The reserved nature of the prognosis of such tumours is emphasized, as well as the fact that their diagnosis is often interoperative.
