Stretta Anti-Reflux Radiofrequency Procedure

Stretta therapy involves the use of radiofrequency energy to tighten the oesophagus sphincter muscle.

The lower oesophageal sphincter muscle (near where the stomach meets the oesophagus) is treated with a special radiofrequency catheter, which remodels the tissue in order to improve the barrier function, reducing the unpleasant symptoms of reflux.

This is carried out as an outpatient procedure. Patients can usually return to normal activities the following day.

Stretta Procedure

  1. The physician places the Stretta catheter through the patient’s mouth and into the valve between the stomach and oesophagus.
  2. Radiofrequency energy is delivered to the muscle of the lower oesophageal sphincter and gastric cardia to create small thermal lesions.
  3. Over time, the lesions heal and the tissue contracts.
