Syndrome of duodenal compression by the superior mesenteric artery following restorative proctocolectomy: a case report and review of literature.

CONTEXT: Restorative proctocolectomy with anastomosis of an ileal pouch to the anal canal is a new and rare cause for triggering the syndrome of duodenal compression by the superior mesenteric artery. Restorative proctocolectomy requires assessment of the position of the duodenum in relation to aortomesenteric constriction to avoid the occurrence of duodenal compression by the superior mesenteric artery. CASE REPORT: The authors report on a case of this syndrome in a patient with familial adenomatous polyposis and review the literature on the etiopathogenesis, diagnosis, treatment and prevention of this unusual entity.
