If the 10 hospitals that are doing the study include Dr. Bessler @ NY Presbyterian, Mt. Sinai Hospital in NYC, Brigham by Dr. Thompson in Mass., Dr. Bard who started the study, the Dr. in Chicago (cannot remember his name) etc.....they are supposed to reduce the pouch as well. Please read the info below from one of the links in regards to the study, thanks:
"Weight regained after gastric bypass surgery may be caused by an enlarged pouch and/or stretching of the stoma, the opening between the stomach pouch and small intestine. The EROS Procedure is a new surgical option to treat weight regain in post-gastric bypass patients. The procedure uses FDA-cleared endoscopic instruments to decrease pouch and stoma size and recreate a restriction to encourage weight loss. It does not require surgical incisions. In the procedure, an endoscopic suturing device is introduced through the mouth. Sutures are placed in the stomach pouch and stoma to reduce their size which slows the exit of food from the stomach pouch, enabling patients to better restrict food intake and reverse their weight re-gain. The EROS procedure is expected to provide important advantages over surgery, including, minimal post-operative pain, fast recovery time, and no scarring."
It does both, it reduces the stoma and the pouch.
