Firm Tests Non-Invasive Stomach Stapler

The New York Times has written about an experimental device that can perform stomach stapling surgery without any incisions. Satiety Inc. has developed a procedure called Toga, for transoral gastroplasty, in which a stapler is passed down the patient's throat and staples his or her stomach from the inside. It is part of a trend toward using natural orifices as entry points for surgery, avoiding the need to make any incision at all.

Firm Tests Non-Invasive Stomach Stapler

Satiety is conducting a trial in hopes of getting FDA approval; the Times article chronicles one of the procedures during the trial. Early indications are that the Toga procedure offers "a drastic reduction in side effects and risk" compared to conventional bariatric procedures.First, a dilator is pushed down the throat to widen the esophagus. Then a two-foot-long tube containing the stapler is inserted. The patient's stomach is inflated with carbon dioxide to create more working space. Then the stapler is positioned and the tube is opened. A wire emerges from the stapler to push aside the folds of the stomach, then a vaccum pump draws in the front and back walls of the stomach into the device to be stapled together. The stapler only holds one row of staples, so for each additional row needed, the stapler is withdrawn, rinsed, reloaded, pushed back down the patient's throat, and repositioned.
