Transoral Outlet Reduction Endoscopy (TORe) is a non-surgical endoscopic weight loss procedure for patients who previously had Roux-en-Y gastric bypass (RYGB). Over time, the stomach pouch or stoma (the opening between stomach and small intestine) can stretch, reducing fullness cues and causing weight regain or dumping syndrome.

TORe restores the anatomy by shrinking the stoma and sometimes the pouch, helping patients feel full sooner and support renewed weight loss.

How the TORe Procedure Works

• Performed with an endoscope—no external incisions
• Flexible tube with a camera and suturing tools inserted through the mouth under anesthesia
• Specialized sutures tighten the stoma (and sometimes the pouch)
• Typically under an hour, with same-day discharge

Benefits of TORe

• Minimally invasive (no cutting or stapling)
• Lower risk and quicker recovery than revision surgery
• Can produce 10–20% total body weight loss
• Improves obesity-related conditions and dumping syndrome
• Can be repeated if necessary
• Often covered by insurance

Risks & Considerations

• Possible risks: bleeding, infection, or perforation (rare)
• Not suitable for everyone—requires evaluation by a bariatric specialist
• Works best when combined with a structured aftercare plan (nutrition counseling, lifestyle changes, and support groups)

Expected Results After TORe

Patients typically lose 10–20% of body weight after TORe, with best results achieved when following a comprehensive bariatric aftercare plan.
