A Case Report of Superior Mesenteric Artery Syndrome after abdominoperineal Excision of Rectal Cancer

We experienced a case of superior mesenteric artery syndrome (SMAS) as a post-operative complication after abdominoperineal excision for rectal cancer in 65-year-old man. Duodenal compression by the overlying superior mesenteric artery may be caused by strong traction of the mesenterium to the pelvic floor which was made by postoperative adhesion. Although the mobilization of the third part of the duodenum was performed, the symptoms reappeared 3 months after surgery. Therefore, we performed side-to-side duodenoje-junostomy. The patient has continued to make satisfactory progress 8 years after the reoperation. SMAS should be considered as a postoperative ompliation after abdominal surgery, although it may be rare. Side-to-side duodenojejunostomy may be recommended.
