Abstract
The cases of 32 patients who had primary symptomatic tumors of the small bowel were studied in an attempt to better define the clinical patterns. 17 had adenocarcinomas, two of which were in the duodenum, 14 in the jejunum and one in the ileum. Two patients had carcinoid, six had lymphoma or lymphosarcoma and two had sarcomas. There were 5 benign tumors. 14 patients had a clinical pattern of intermittent small bowel obstruction characterized by recurrent attacks of crampy midabdominal pain. 12 patients had a pattern of blood loss which was characterized by intermittent massive bleeding in the benign tumors and anemia and constant occult blood loss in the malignant ones. Roentgen studies showed the tumor in 18 of the 29 cases studied with contrast media and led to the diagnosis in two other cases by disclosing evidence of obstruction. 29 patients had an operative procedure and metastases were found in 15. Three patients with adenocarcinoma of the jejunum survived for more than 5 years while 7 of 8 with sarcoma are either alive or survived 5 years.
