title: Occult blood loss from small bowel tumours. Case report.
abstract: We report 4 patients who presented with occult blood loss, from a small bowel adenocarcinoma, in whom there was considerable delay in diagnosis. The difficulty in diagnosis and the role of CT scanning is discussed. We recommend a careful laparotomy when endoscopic and radiological investigations fail to reveal the source of blood loss.
