Superior mesenteric artery syndrome treated with single-incision laparoscopy-assisted duodenojejunostomy.

Superior mesenteric artery (SMA) syndrome is an uncommon disease resulting from compression and partial obstruction of the third portion of the duodenum from the SMA. A 77-year-old man, who did not have a history of surgery, experienced repeated vomiting and developed abdominal distension. Abdominal CT showed a narrowed third portion of the duodenum, with a distended stomach and proximal duodenum. The patient was diagnosed as having SMA syndrome and was initially treated conservatively, but his condition did not improve. Single-incision laparoscopy-assisted duodenojejunostomy was performed. The patient recovered well and was discharged from hospital on postoperative day 8. Laparoscopic treatment is feasible for the treatment of SMA syndrome given its safety and minimal invasiveness. This is a report of the first case of single-incision laparoscopy-assisted duodenojejunostomy. This procedure is safer and less invasive than a conventional laparoscopic approach in a patient with SMA syndrome.
