Abstract

Background: Superior mesentery artery syndrome (SMAS) is a rare vasculo-anatomic occlusive pathologic entity for which a period of conservative medical management is advocated with surgery reserved for nonresponsive cases. We present our management plan that entails a single admission approach and complete rendering of medical and surgical treatment to the patient on a background of the socioeconomic and cultural trends prevalent in this geographic region.

Methods: A retrospective analysis of 22 cases of SMAS admitted in our health care system who underwent a period of preoperative conditioning followed by laparoscopic duodenojejunostomy from September 2009 to June 2019 was performed. Patients were followed up at regular intervals.

Results: The mean follow-up of the cohort was 41.2 months (2-108 months). The median length of stay was 6 days. The mean postoperative stay was 4.13 days. A subgroup of six patients who had severe physiological depletion required a period of preoperative optimisation. Five of the 22 (22.7%) patients suffered from postoperative complications in the form of delayed return of bowel functions. None of the patients had complications more than Clavien-Dindo grade 2 with no mortality. Long-term data are available for 19 patients (86.3%) which showed no symptom recurrence.

Conclusion: Management of SMAS that entails an antecedent medical therapy followed by surgery can be accomplished in a single admission with good to excellent results in the intermediate and long-term follow-up. Physiologically depleted patients do require a period of intensive preconditioning but on long-term follow-up, they have excellent results.
