Revision using the OverStitch™ Endoscopic Suturing System

There is new hope for patients experiencing weight gain after bariatric surgery.

Revision using the OverStitch™ Endoscopic Suturing System is a minimally invasive procedure that is designed to help patients who are struggling with weight gain after gastric bypass bariatric surgery.

Why do some patients re-gain weight?
Studies suggest that some patients may regain weight after their initial weight loss surgery caused by the gradual stretching of the stomach pouch outlet. If the stomach pouch or stoma gradually stretch, patients start eating larger meals and may regain weight. These patients now have an option.

The OverStitch™ Endoscopic Suturing System enables advanced endoscopic surgery by allowing your surgeon to place full-thickness sutures through a flexible endoscope passed through the patient’s mouth. Your surgeon can safely place the same quality of sutures used during normal abdominal surgery.

This is a minimally invasive endoscopic procedure that is performed in an outpatient setting, which means you go home the same day, and leaves no external scars. With this new technology, the OverStitch™ system provides a less invasive solution for revision bariatric procedures.

While weight regain after RYGB can be the result of multiple factors, several recent studies indicate that weight regain is correlated with a dilated or larger gastrojejunal (GJ) stoma diameter as well as an enlarged gastric pouch.1-4 Data in one study showed that five years after RYGB, each 10mm increase in the GJ stoma diameter was associated with an 8% increase in weight regain.3

Many research studies suggest that endoscopically reducing the patient’s GJ stoma diameter, in a procedure known as transoral outlet reduction (TORe), is effective in treating or preventing weight regain.1-5 In addition, other current studies indicate that OverStitch with full-thickness sutures offers significant advantages over other endoscopic suturing methods.2, 4, 5

Recent research comparing OverStitch with several traditional techniques and devices for bariatric revision suggests that Overstitch is a promising alternative.


The OverStitch™ Endoscopic Suturing System continues to gain recognition as a viable tool in addressing patient weight regain following bariatric surgery.
