TIF Surgery Procedure

Incisionless Acid Reflux Treatment in Houston

TIF: Transoral Incisionless Fundoplication

TIF (Transoral Incisionless Fundoplication) treats the underlying cause of GERD without incisions. The surgery is performed through the mouth using a device called EsophyX. EsophyX enables the manipulation and plication of tissue around the esophagus to create a partial wrap of the stomach. This is believed to reconstruct the weakened lower esophageal sphincter to prevent acid reflux. The procedure is heavily marketed as a non-surgical alternative to the traditional Nissen Fundoplication.

TIF however is not a Nissen. A key step in Nissen fundoplication surgery is the complete mobilization of the stomach fundus to create a complete wrap. The mobilized and repositioned stomach fundus prevents acid from refluxing into the esophagus. This mechanism is not duplicated by TIF because the stomach fundus cannot be dissected and mobilized during TIF.
