Superior Mesenteric Artery Syndrome Managed with Laparoscopic Duodenojejunostomy

Superior mesenteric artery (SMA) syndrome is a rare disorder that may be managed surgically if conservative management fails. Different surgical techniques have been described, division of the ligament of Treitz, gastrojejunostomy, and duodenojejunostomy. The aim of this case series is to show that laparoscopic duodenojejunostomy is a safe and technically feasible management for superior mesenteric artery syndrome.

In this case series, we retrospectively identified all patients who underwent laparoscopic duodenojejunostomy for SMA syndrome in our tertiary university center between December 2016 and July 2019. Data collected included demographics, presenting symptoms, comorbidities, pre and postoperative body mass index (BMI), operative approach, operative blood loss, operative duration, clinical and radiological results, in hospital/30-day complications, mortality, and postoperative follow-up outcomes.

We identified eleven patients, 10 females and 1 male, with a median age 23 years (range 17-43 years). All patients had refractory symptoms after a minimum of two months of conservative management and subsequently underwent laparoscopic duodenojejunostomy. There were no intraoperative complications and no in-hospital or 30-day postoperative mortality or complications were identified. Follow-up data showed complete resolution in 73% of patients (n = 8) and only one patient with no improvement postoperatively. Results also showed a median BMI increase of 2 kg/m² (range 1-9 kg/m²) at a median follow-up of 16 months (range 4-48 months).

Laparoscopic duodenojejunostomy is a safe treatment option for SMA syndrome and should be considered when patients do not respond to conservative management.
