Transoral Outlet Reduction (TORe)
A non-surgical endoscopic procedure that tightens the stomach-intestine connection to restore weight loss after gastric bypass.
Plain English
Patient-Friendly Explanation
Transoral outlet reduction is a non-surgical endoscopic procedure for patients who have regained weight after gastric bypass surgery. Using a small device passed through the mouth — no incisions needed — the surgeon tightens the connection between the stomach pouch and small intestine, slowing food passage and restoring the feeling of fullness. It is an outpatient procedure with a short recovery time.

Clinical Definition
Transoral outlet reduction (TORe) is an endoscopic revisional procedure performed via an endoscope inserted through the mouth, targeting weight regain after Roux-en-Y gastric bypass (RYGB). The gastrojejunal anastomosis — which commonly dilates over time, accelerating gastric emptying and reducing satiety — is reduced in diameter using full-thickness suturing devices (e.g., OverStitch). Mean excess weight loss of 8–15% at 12 months is reported in systematic reviews, with a favourable safety profile compared to surgical revision. It requires no abdominal incisions and is typically performed on an outpatient basis.
