Core Tip

Core Tip: Given the chronic, progressive nature of obesity, weight recurrence after Roux-en-Y gastric bypass (RYGB) is common. Transoral outlet reduction (TORe) is a minimally invasive, same-day, Food and Drug Administration-authorized endoscopic procedure that restricts the gastrojejunal anastomosis to facilitate safe and clinically meaningful weight loss in patients experiencing post-RYGB weight recurrence. To date, nearly all TORe literature has originated in the academic setting. Here, we show that TORe is safe, effective, and technically feasible in the community setting when performed by an experienced bariatric endoscopist and coupled with longitudinal aftercare.
