The only system FDA-authorized to endoscopically address a previous gastric bypass.

The TORe procedure

Transoral Outlet Reduction (TORe) is an endoscopic procedure to revise a previous Roux-en-Y gastric bypass and
is performed with the Apollo ReviseTM System.
TORe leaves no scars and helps you get back on track by fixing anatomic changes that may have caused weight gain.

A surgeon or gastroenterologist performs Transoral Outlet Reduction using a camera inserted down your mouth and special, FDA-authorized device to narrow the connection between your stomach and small intestines. This can help you lose weight again or stop you from gaining more weight.

  • No incisions or scars

  • Same-day procedure for many patients

  • Return to normal activities a few days after procedure

  • Lower adverse event rate than traditional surgical approaches1
