A Case Series on Superior Mesenteric Artery Syndrome Surgical Management, Single Institution Experience

Compression of duodenum by Superior Mesenteric Artery (SMA) causing proximal intestinal obstruction is an uncommon condition. Treatment of this condition involves conservative management initially followed by surgical management in those patients who have persistent symptoms. This case series evaluates surgical management and outcome of six patients after one year, who presented with SMA syndrome and describes a brief review of literature. Three patients underwent open duodenojejunostomy and the rest three underwent laparoscopic duodenojejunostomy. All patients had uneventful postoperative recovery. Postoperative requirement of analgesics was less in laparoscopic group versus open group. All the three patients in laparoscopic group could be mobilised out of bed on the day of the surgery itself. Mean duration of hospital stay was seven days for open surgery group and three days for the laparoscopy group. Outcome in terms of resolution of abdomen pain and vomiting was similar in both the groups. Four patients were asymptomatic after one year of follow up. A high index of clinical suspicion is needed for the diagnosis of SMA syndrome. Laparoscopic approach is feasible, safe, less morbid and effective as compared to open surgery. In the presence of facilities and surgical expertise, laparoscopic duodenojejunostomy should be considered the procedure of choice for SMA syndrome. Majority of patients remain symptom free at one year follow up.
