Duodenal obstruction caused by acute appendicitis with intestinal malrotation in an adult. A case report.

A 55 year old man with a short history of continuous vomiting and recent episodes of midabdominal pain and high fever was discovered to have a complete duodenal obstruction caused by acute appendicitis and intestinal malrotation. A fibrous adhesion caused by the inflamed appendix in the high caecum involved the duodeno-jejunal junction. This case is unique in that the onset of acute appendicitis triggered duodenal obstruction in the presence of an asymptomatic malrotation.
