Use of a New Endosurgical Operating System for Endoscopic Stoma and Pouch Reduction in Patients with Weight Regain Following Roux-en-Y Bypass Surgery

Summary
The Mount Sinai Program for Surgical Weight Loss recently completed a multiinstitutional study to investigate a new less invasive surgical option to treat weight regain in post-gastric bypass patients. Most gastric bypass patients obtain excellent weight loss after gastric bypass surgery. Some patients, however, experience some weight regain years after their bypass surgery. Such weight regain may be caused by an enlarged pouch or stoma (the connection between the stomach pouch and intestine).

We used an FDA-cleared endoscopic instrument to decrease pouch and stoma size in order to improve weight loss. This technique does not require surgical incisions. Rather, the endoscopic suturing device is introduced through the mouth like an upper endoscopy. Sutures are placed in the stomach pouch to reduce the size of the gastric pouch.

This approach is intended to provide a less invasive alternative to laparoscopic or open surgical revision for patients who initially did well with their bypass but have subsequently regained some of their weight back.

The study is now concluded, but if you are interested in this therapy, you may be a candidate for endoscopic pouch and reduction outside of the research study.
