Clinical Research Studies

Roux-en-Y gastric bypass (RYGB) is a commonly performed bariatric surgery procedure aimed at promoting weight loss in eligible obese patients. While initial weight loss can be very successful for many patients, some patients will experience weight regain despite the procedure. One contributing etiology of this weight regain is dilation of gastrojejunal anastomosis. Transoral outlet reduction (TORe) is an endoscopic treatment for weight regain, in which an endoscopic suturing system is utilized to reduce the gastrojejunal anastomosis. The purpose of this study is to further understand patient experiences, symptoms, and satisfaction with the endoscopic procedure of Transoral Outlet Reduction (TORe). In addition, the study will evaluate total body weight loss and weight regain in patients who have undergone TORe. As well as assess patient reported outcomes including subjective weight loss, symptoms before and after the procedure (including pain, nausea, vomiting, dyspepsia, food tolerance), tolerance of the procedure both individually and in comparison to original surgery, and willingness to undergo repeat TORe if indicated.
