Background: Laparoscopic Roux en -Y Gastric Bypass (LRYGB) is one of the most commonly performed procedures for the management of morbid obesity. The success of this procedure requires the creation of a small gastrojejunostomy, which sometimes can become stenotic. The treatment of choice for this complication is endoscopic balloon dilatation. This study aims to evaluate the safety and effectiveness of the management of gastrojejunal anastomotic stricture (GJAS) using Savary-Gilliard dilators guided by endoscopy. Methods: 708 patients underwent LRYGB. The average age was 41 years, and mean bodymass index was 43 kg/m². Patients with symptoms suggesting stenosis of the anastomosis underwent upper gastrointestinal endoscopy. When confirmed, those stenosis were managed endoscopically with Savary-Gilliard dilators. Results: GJAS was confirmed in 23 patients (3.24%). A total of 36 dilatations were performed in these patients, which resulted in an average of 1.5 sessions per patient. It was necessary to perform one dilatation to 20 patients (87%), three dilatations in one patient (4%), and four or more in 2 patients (9%). The average time between surgery and GJAS dilation was 10 weeks. All dilations were performed on an outpatient basis. Conclusion: The management and treatment of GJAS after LRYGB can be done as an outpatient procedure using Savary-Gilliard dilators, which are effective and safe.
