BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been established as a safe and effective procedure for morbid obesity management. Amongst some of the postoperative complications are gastrojejunal (GJ) anastomotic strictures, with an incidence of 3 to 27 % in some series. This study evaluates the incidence of GJ strictures using a 21-mm circular stapling device and its response to treatment with endoscopic balloon dilation. METHODS: A retrospective chart review was conducted of patients who underwent LRYGB between January 2007 and September 2010. We used our previously published technique of retrocolic, retrogastric Roux-en-Y bypass, using a 21-mm circular stapler to construct the gastrojejunostomy. Postoperatively, patients with persistent food intolerance underwent an endoscopy. Those found to have a GJ stricture (defined as inability to pass the endoscope beyond he anastomotic site) underwent pneumatic dilation with a 12-mm balloon. RESULTS: A total of 338 patients underwent LRYGB. Median follow-up was 57.6 weeks (8-137). Twenty-two patients underwent an endoscopy due to food intolerance. Sixteen patients (4.7 %, 16/338) were identified with GJ stricture and received at least one endoscopic dilation. The other six patients had a normal endoscopic evaluation. GJ strictures presented at an average of 35 days (13 to 90 days) postoperatively. Four patients underwent two endoscopic interventions, and one underwent three endoscopic interventions. CONCLUSIONS: We hereby demonstrate that the construction of GJ anastomosis with a 21-mm circular stapler is associated with a low stricture rate using our standardized technique. Strictures are amenable to balloon dilatation with subsequent long-term resolution of symptoms.
