We identified articles describing technical feasibility, safety, efficacy, and adverse outcomes of overstitch endoscopic suturing system for transoral outlet reduction in patients with weight regain following Roux-en-Y gastric bypass(RYGB). All studies that contained material applicable to the topic were considered. Retrieved peer-reviewed original and review articles were reviewed by the authors and the data extracted using a standardized collection tool. Data were analyzed using statistical analysis as percentages of the event. RESULTS: Four original published articles which met our search criteria were pooled. The total number cases were fifty-nine with a mean age of 46.75 years(34-63 years). Eight of the patients included in those studies were males(13.6%) and fifty-one were females(86.4%). The mean time elapsed since the primary bypass surgery was 5.75 years. The average pre-endoscopic procedure body mass index(BMI) was 38.68(27.5-48.5). Mean body weight regained post-RYGB surgery was 13.4 kg from their post-RYGB nadir. The average pouch length at the initial upper endoscopy was 5.75 cm(2-14 cm). The pre-intervention anastomotic diameter was averaged at 24.85 mm(8-40 mm). Average procedure time was 74 min(50-164 min). Mean post endoscopic intervention anastomotic diameter was 8 mm(3-15 mm). Weight reduction at 3 to 4 mo post revision noted to be anaverage of 10.1 kg. Average overall post revision BMI was recorded at 37.7. The combined technical and clinical success rate was 94.9%(56/59) among studied participants. CONCLUSION: Endoscopic suturing can be technically feasible, effective and safe for transoral outlet reduction in patients with weight regain following RYGB.展开更多
