title: Single-contrast examination of the duodenum following enteroclysis.
abstract: Important abnormalities of the distal duodenum can be missed on the usual enteroclysis examination because of placement of the intubation tube beyond the ligament of Treitz. This can be avoided by extending the examination to include visualization of the duodenum during withdrawal of the nasojejunal tube. On the basis of the case reported here this procedure is suggested for patients with unexplained upper gastrointestinal bleeding in whom the remainder of the small bowel is normal.
