Superior Mesenteric Artery Syndrome Complicated by Pancreatitis

Abstract

The threefold purpose of this study is to review the history of the existence and diagnosis of superior mesenteric artery (SMA) syndrome, to add to the weight of evidence of such a syndrome, and to describe the unusual complication of pancreatitis in SMA syndrome. The authors' methods include the review of historical and current literature and a case presentation. Their patient, who presented with small bowel obstruction after profound weight loss, was evaluated. She was found to have cutoff of the third portion of the duodenum by the superior mesenteric artery. This was complicated by an elevated amylase level. After conservative treatment to restore her weight with enteral and parenteral nutrition was unsuccessful, the authors opted for surgical repair to correct the obstruction. This was successful. They conclude that SMA syndrome is a real entity. It may be complicated by pancreatitis. Surgical correction may be needed and can be successful in restoring bowel function.
