Abstract
BACKGROUND: Superior mesenteric artery syndrome (SMAS) is a rare condition caused by partial obstruction of the third portion of the duodenum by the SMA anteriorly and aorta posteriorly. Laparoscopic duodenojejunostomy has been described as a safe and feasible surgical intervention with favorable short-term outcomes. However, descriptions of intermediate outcomes are lacking in the literature. METHODS: A retrospective chart review was performed on patients who underwent minimally invasive duodenojejunostomy from March 2005 to August 2015 at our healthcare system with greater than 6-month follow-up. RESULTS: Eighteen patients with mean age of 31.2 were identified. There were 4 men and 14 women. Patients' diagnosis was made by clinical presentation with radiographic confirmation. Mean weight loss preoperatively was 13.9 kg, representing 24.1 % total body weight loss. There were no intraoperative complications. Postoperatively, 2 patients developed prolonged ileus. One underwent exploratory laparotomy and washout for presumed leak, but none was identified. Three patients were readmitted within 30 days; 2 for intolerance to enteral intake with dehydration, and 1 for closed-loop obstruction requiring laparoscopic lysis of adhesions. The average and median length of follow-up were 27.7 and 26.0 months, respectively. Patients gained an average of 2.2 kg with an increase in body mass index of from 19.6 to 20.4 m/kg2. Although 14 of 18 patients reported initial symptom improvement, at latest follow-up, only 6 patients reported symptomatic improvement or resolution. Three were diagnosed with global dysmotility, and 1 underwent intestinal transplant. Two were diagnosed with gastroparesis, and 1 underwent a laparoscopic gastric electric stimulator placement and pyloroplasty. There were no mortalities. CONCLUSION: Duodenojejunostomy is the most common surgical intervention in management of SMAS. Our intermediate follow-up reveals infrequent improvement and rare resolution of preoperative symptomatology. Patients had a modest average weight gain postoperatively. This may suggest that different preoperative workup and treatment is indicated.
