title: Carcinoid of the small intestine.
abstract: Carcinoid tumour was the most common small bowel tumour found in this series of 179 patients. It occurred in 24% of patients. Forty-six percent of patients were asymptomatic during life, the tumours being found either at autopsy or during other surgical procedures. Of those that were symptomatic, half presented with intestinal obstruction and the rest with long-standing symptoms. An abdominal mass, which occurred in 14% of cases, is an uncommon physical finding since the majority present as small submucosal tumors. Fifty-eight per cent overall and 72% of those having surgery had evidence of regional spread, either by local invasion or in the form of regional nodal involvement. Seven per cent of patients have died of their disease. Excisional surgery should be performed for all cases where feasible, and repeated for recurrent symptoms.
