Transoral outlet reduction is done while you are under anesthesia.

It lasts about 1-2 hours, and most patients go home the same day.

To perform transoral outlet reduction:

  • The surgeon inserts an endoscope into your mouth and guides it into the stomach pouch to examine the inside of your stomach.
  • Heat treatment is applied to the edge of the gastric outlet to help it narrow & close.
  • A suturing device is placed on the end of the endoscope to tighten the gastric outlet.
  • The gastric stoma diameter is reduced by ~80%, and the endoscope is removed.
  • Decreasing the opening’s size will allow you to feel full and help you lose weight.
