TORe: A tailored procedure for post-bariatric patients

A clinically proven, minimally invasive option for weight regain after gastric bypass.

Introducing Transoral Outlet Reduction (TORe)

transoral-outlet-reduction-tore

An estimated 15,000 endoscopic revisions of bariatric procedures performed worldwide.1

More than 150 clinical papers and abstracts have been published on TORe.2

Transoral Outlet Reduction (TORe) is a minimally invasive procedure designed for patients who have regained weight after gastric bypass. By tightening the connection between the stomach and small intestine, TORe helps restore portion control and supports long-term weight loss.

No incisions or scars

Most patients typically go home the same day

Low adverse event rate3

   

How the TORe procedure is performed

TORe is performed under general anesthesia by a trained gastroenterologist or surgeon, using the OverStitch™ System. The procedure involves a flexible scope inserted through the mouth, avoiding incisions and minimizing downtime. It safely restores the stomach’s restrictive function to help patients lose weight again, with most patients typically discharged the same day.

Support Long-Term Outcomes

Long-term studies support durable weight loss at 5 and 7 years.5,7

A comparative study demonstrated a lower rate of adverse events with TORe compared to surgical revisions, whilst achieving similar outcomes in long-term efficacy.3
