Transoral outlet reduction (TORe) is a minimally invasive, endoscopic procedure that can help you if you've regained 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. Individuals can sometimes regain weight after gastric bypass because the gastric outlet (the connection between the stomach and small bowel) expands, making you feel less full and able to eat more, which can cause you to regain weight.
TORe can repair your gastric outlet by reducing its size. During this procedure, your doctor inserts stitches into your gastric outlet through an endoscope — a flexible tube with a camera and a suturing device attached. Since this outpatient procedure is minimally invasive, it has a reduced risk of complications than conventional surgical revision of a gastric bypass.
Patients who have undergone TORe feel full earlier in their meals and may lose weight —and maintain the weight loss — in the years following the procedure. Like other weight loss programs, however, a commitment to a healthier lifestyle will help to ensure long-term success.
In addition to helping you lose weight you may have regained after gastric bypass, transoral gastric outlet reduction (TORe) may assist you in lowering your blood sugar and address other weight-related health risks, including:
Your doctor will perform transoral outlet reduction (TORe) in the hospital under general anesthesia. Before your procedure, you will need to follow specific preparation instructions, which you will discuss with your care team in advance.
This procedure typically takes approximately one hour to complete and the majority of patients go home the same day. Please note that you must have an adult present to drive you home in order to be discharged.
Following the procedure, you must adhere to a modified diet that starts with liquids and moves on to semisolid foods over several weeks before returning to a normal diet. Follow-up with a nutritionist is a required part of the program.
You may have some abdominal discomfort and nausea in the days after the procedure. You may be prescribed medication to treat these potential side effects.
