Stretta Therapy, a non-ablative radiofrequency treatment for GERD, was called "effective, safe and durable following 15 years of worldwide use" and cited as a "viable complement or alternative to medical and surgical treatment" in a newly-published clinical review of endoscopic techniques for gastroesophageal reflux disease (GERD). Authors Wai-Kit Lo, MD, MPH and Hiroshi Mashimo, MD, PhD of Harvard Medical School, examined multiple alternatives to PPI therapy or surgery, including Stretta and other devices such as endoscopic plication and suturing, as well as injectable and implantable bulking agents. Their findings have been published in the Journal of Clinical Gastroenterology.
