Occasionally after gastric bypass the pouch may stretch out. ROSE, which stands for Restorative Obesity Surgery Endoscopic, is for patients who may need to restore the size of the pouch after an initial procedure has produced weight-loss. Before the development of this incision-free procedure, patients who regained weight after gastric bypass generally had few treatment options.
Scarring and adhesions related to the initial bypass procedure can make open or laparoscopic revision surgery very challenging. Revision surgery procedure time is typically longer than the original bypass procedure and patients can be up to three times more likely to develop a complication following revision surgery. Therefore, most patients who regain weight after gastric bypass opt not to undergo open or laparoscopic surgical revision after weighing the risks and benefits.
