Superior mesenteric artery (SMA) syndrome is rare disorder, which is caused by a reduction in the aortomesenteric angle causing a duodenal obstruction. It is usually occurs after a period of weight loss, nausea, and vomiting by a partial obstruction of the third portion of the duodenum. If conservative management fails then a laparotomy with a duodenojejunostomy is indicated. Recently, a minimally invasive or laparoscopic approach to the retroperitoneum or duodenal detachment was introduced. Although the role of a laparoscopy in managing SMA syndrome is not clearly defined, a laparoscopic duodenojejunostomy may be an alternative approach to the surgical treatment of SMA syndrome cases. Two cases of superior mesenteric artery syndrome that were treated laparoscopically after medical therapy failure are described. The 4-port procedure was performed. A dilated bowel on the third portion of the duodenum was observed below the transverse mesocolon and to right of the superior mesenteric artery. A proximal loop of the jejunum was anastomosed to the duodenum using an endoscopic GIA stapler. The surgery time and hospital length of stay were acceptable. No complications were encountered in this study. A laparoscopic duodenojejunostomy is a feasible alternative option for treating SMA syndrome. It provides the benefits of being a definitive and minimally invasive surgical technique in a duodenal obstruction.

Superior mesenteric artery (SMA) syndrome is a rare disease in which the third portion of the duodenum is compressed by SMA. There are many causes leading to the SMA syndrome, however it's extremely rare that aortic aneurysm causes a SMA syndrome. We report a case of a successfully treated SMA syndrome due to an abdominal aortic aneurysm in a renal transplant recipient. The patient was a 52-yr-old woman with a thin stature (weight 40 kg, height 164 cm). She received a renal transplant 8 yr before, and had hypertension and abdominal aortic aneurysm. Her SMA syndrome developed in a prolonged supine position for the accidental rib fractures and was diagnosed by clinical and radiological findings. After a surgical correction (resection of an aneurysm and aortobiiliac bypass with an inverted Y graft), her symptoms relieved without deterioration of the graft function.
