Superior mesenteric artery syndrome following ileal J-pouch anal anastomosis. An iatrogenic cause of early postoperative obstruction.

Abstract

This is the first case report of the superior mesenteric artery syndrome developing in a patient following total proctocolectomy and ileal J-pouch anal anastomosis. In addition, this is the first demonstration of this syndrome using abdominal CT scan. A 22-year-old veteran underwent total proctocolectomy for left-sided ulcerative colitis because of failure of medical therapy. At operation an ileal J-pouch anal anastomosis was constructed. Following operation, the patient developed an intestinal obstruction. Abdominal CT scan demonstrated scant retroperitoneal fatty tissue, massive dilatation of the duodenum proximal to the midline, and tapered narrowing of the duodenum between the superior mesenteric artery and aorta. These findings indicated superior mesenteric artery syndrome: arteriomesenteric obstruction of the duodenum. Based on the experience of this case, the authors believe that compression of the duodenum by the superior mesenteric artery may be a common but unsuspected cause of prolonged postoperative ileus or early postoperative obstruction following ileal pouch anal anastomosis.
