Malignant tumors of the small intestine account for about 2% of all gastrointestinal malignancies. The majority of these lesions are adenocarcinomas, followed by carcinoid tumors, lymphomas, and sarcomas. The most common site for carcinoid tumors is the appendix, followed by the jejunoileum. The most clinical manifestation of jejunoileal carcinoids is small-bowel obstruction. Gastrointestinal bleeding from jejunoileal carcinoids is rare but is surgically correctable. It is often difficult to locate the source of small intestinal hemorrhage prior to exploratory laparotomy. We recently treated a patient with multiple jejunoileal carcinoids associated with massive gastrointestinal hemorrhage. This case is presented along with a complete review of the pertinent literature to update the workup and treatment of bleeding small-bowel tumors.
