Patient-Friendly Explanation

After gastric bypass surgery, some patients may experience weight regain years later because the opening between the stomach pouch and small intestine gradually stretches. TORe is a non-surgical procedure done through the mouth using an endoscope — no incisions needed — to tighten this opening back to its original size. This helps patients feel full on smaller portions again and can restart weight loss without the need for repeat surgery.

Clinical Definition

Transoral Gastric Outlet Reduction (TORe) is an endoscopic revisional procedure for patients with weight regain after Roux-en-Y gastric bypass (RYGB), typically due to dilation of the gastrojejunal anastomosis. Using a flexible endoscope inserted transorally, the gastroenterologist places full-thickness sutures to reduce the anastomotic diameter from ≥20 mm to approximately 8–10 mm, thereby restoring restriction. Systematic reviews report mean excess weight loss of 10–15% at 12 months post-TORe, with a favourable safety profile compared to surgical revision. The procedure is performed on an outpatient basis with minimal recovery time.

Why It Matters

Weight regain after bariatric surgery is a common concern, and surgical revision carries higher risks. TORe offers a safer, scar-free option for eligible patients. At NuLifeCare, we evaluate patients who have experienced post-bypass weight regain and can discuss whether TORe or other revisional strategies are appropriate for your situation.
