[Primary small intestine malignancies].

The frequency of malign tumors in the small intestine was 1% of all malign tumors of the digestive tract. 4% of malign tumors found by autopsy in the digestive tract were located in the small intestine. 12 months passed between first symptoms and operative therapy. In 80% we found local or distant metastases. In only 5 of 11 cases a curative resection was attempted. A great number pf small intestine tumors were identified by autopsy for the first time. A curative resection depends on an early diagnosis. Ileus, massive bleeding, extreme weight loss and palpable mass are late physical findings. Obstipation, diarrhea, occult intestinal bleeding and abdominal pain indicate after subtle inquiry X-ray of the small intestine, gastroduodenoscopy and angiography. If there is no result an early laparotomy should be performed.
