Bariatric Revision

What’s Bariatric Revision?

Bariatric revision, or trans-oral gastric outlet reduction, is a non surgical outpatient procedure. Sutures are used to tighten the gastrojejunal anastomosis and restore it to its original size in patients experiencing weight regain after gastric bypass.

Bariatric Revision

Who is bariatric revision for?

Bariatric revision is suited for patients who previously underwent gastric bypass surgery, but who are now experiencing weight regain.

How does bariatric revision work?

This is an outpatient endoscopic procedure. It is not a surgery. There are no incisions or scars. The endoscopist advances an endoscope (a tube with a camera and a light on its tip) through the mouth to the gastric pouch. The scope is equipped with a suturing device that allows us to suture the gastrojejunal anastomosis to restore it to its original size. This is performed under sedation. It does not require admission to the hospital. After the procedure the patient will start feeling full after smaller meals again, which helps with weight loss.
