Ligament of Treitz Release With Duodenal Lowering for Pediatric Superior Mesenteric Artery Syndrome.
BACKGROUND: Operative approaches for superior mesenteric artery syndrome (SMAS) vary from Roux-en-Y duodenojejunostomy to the more conservative division of the ligament of Treitz with inferior duodenal derotation known as the Strong procedure. We sought to examine outcomes following a modified version of Strong procedure where the duodenum is lowered as opposed to derotated for the management of SMAS.
MATERIALS AND METHODS: We conducted a retrospective chart review of children who underwent surgical management of SMAS between January 2008 and December 2017. An online survey regarding symptom resolution, feeding practices, and the need for additional procedures was distributed. Data are reported as medians with interquartile range (IQR) and proportions as percentages.
RESULTS: Seven patients with a median age of 15 y (IQR 8, 16) and median body mass index of 16.9 (IQR, 12.6, 22.1) were included. Presenting symptoms included pain (71%), nausea (57%), and vomiting (43%). Six patients initially underwent duodenal lowering, whereas one patient underwent duodenoduodenostomy. One patient underwent adhesiolysis for bowel obstruction in the early postoperative period. All patients had symptom resolution at a postoperative follow-up of 22 d (IQR, 15, 45). Two patients had symptom recurrence, and one patient required reoperation. Six patients completed the survey at a median of 2.3 y (IQR, 1.7, 3.2) postoperatively, of which four underwent duodenal lowering. Of these, 75% (n = 3) were asymptomatic. One patient with recurrence reported occasional nausea and emesis but has not required additional surgery.
CONCLUSIONS: Release of the ligament of Treitz with duodenal lowering results in resolution of symptoms in 75% of patients. This operative approach may be considered before performing more complex operations for SMAS.
