Primary small intestinal adenocarcinoma.

Seven patients with adeno-carcinoma of the small intestine were seen over a period of five years. Four were localized to the duodenum, the jejunum was involved in two and the ileum in one. Abdominal pain, weight loss, anemia and obstruction were the most common presenting complaints. Endoscopy was the primary diagnostic modality for the duodenal tumours. Diagnostic accuracy of barium contrast examination was 83%. Curative resections were performed in two patients and palliative surgery in the rest.
