Small bowel melaena: 2 cases diagnosed by angiography.

Two cases of small bowel tumour presenting with melaena are reported. Selective visceral arteriography was found to be invaluable in the management of these cases. The first case presented with intermittent bleeding causing anaemia. Conventional barium studies of the small and large bowel revealed no abnormality. Superior mesenteric angiography revealed a mass lesion in the jejunum, with features characteristic of a leiomyoma. The second case presented with massive gastrointestinal bleeding. Selective visceral angiography was performed initially and revealed a large, mainly avascular, mass lesion in the ileum. Pathological examination showed a leiomyoma which had undergone cystic degeneration. The value of selective angiography in patients with suspected small bowel bleeding is discussed..
