Diagnostic Considerations

The differential diagnosis includes anorexia nervosa and bulimia. In addition, superior mesenteric artery (SMA) syndrome should be differentiated from other causes of megaduodenum or duodenal ileus, including diabetes mellitus, collagen vascular conditions, and chronic idiopathic intestinal pseudoobstruction. Mechanical obstruction secondary to peptic ulcer disease or duodenal web should also be considered.
