[The diagnosis of bleeding small bowel tumours (author's transl)]

Problems concerning the radiological diagnosis of bleeding, malignant, small bowel tumours are discussed with reference to two cases. The need for early selective visceral angiography is stressed; the significance of contrast pooling is pointed out and the value of recognising the tumour in arriving at a diagnosis and prognosis is discussed. In the presence of negative angiographic findings the small bowel enema has proved a very valuable method of examination. The vascular leiomyosarcomas of the small bowel are best demonstrated angiographically, whereas the avascular adenocarcinomas are best shown by small bowel enema.
