Transoral gastric outlet reduction is a minimally invasive procedure that can help patients who regain weight after gastric bypass surgery. While gastric bypass limits the amount of food you can eat and increases your feeling of fullness, its effectiveness can diminish over time. This occurs because your gastric outlet (the connection between your stomach and small bowel) will expand, making you feel less full and able to eat more, which can cause you to regain weight.
Transoral gastric outlet reduction can repair your gastric outlet by reducing its size. During this procedure, your physician inserts stitches into your gastric outlet through an endoscope — a flexible tube with a camera and a suturing device (a tool that makes surgical stitches) attached. Since this outpatient procedure is minimally invasive, it has a reduced risk of complications.
Patients who have undergone this surgery feel full earlier in their meals and may lose weight — and maintain the weight loss — in the years following surgery. Like other weight loss programs, however, a commitment to a healthier lifestyle will help to ensure long-term success and permanent weight loss.
