The Outcome of Endoscopic Radiofrequency Anti-Reflux Therapy (STRETTA) for Gastroesophageal Reflux Disease in Patients with Previous Gastric Surgery: A Prospective Cohort Study.

BACKGROUND/AIMS: STRETTA improves the quality of life and reduces the need for anti-reflux medication in select patients, especially those with uncomplicated gastroesophageal reflux disease (GERD). We aimed to review the outcomes of STRETTA in patients with medically refractory GERD, who had undergone previous gastric surgery.

METHODS

This was a review of a prospective database in a British center. Since 2016, all GERD patients who underwent STRETTA and had a history of previous gastric surgery were studied (n=11). Anti-reflux medication pre- and post-STRETTA was evaluated. The outcomes were assessed objectively by the change in anti-reflux medication and subjectively through a pre- and post-procedure GERD-health-related quality of life (HRQL) questionnaire.

RESULTS

The median length of follow-up was 23 months. Nine patients demonstrated improved GERD-HRQL scores following STRETTA (82%). Of the 7 patients who underwent fundoplication, all reported improved symptoms, with 3 patients discontinuing the medication and 3 patients on a reduced dose of proton pump inhibitor. Four patients underwent surgery other than fundoplication, of which 2 reported improvement and discontinued the proton pump inhibitor. Two patients reported no improvement.

CONCLUSION

This study demonstrates that STRETTA is successful in reducing refractory GERD in patients with previous gastric surgery. The outcomes were comparable to published outcomes in patients with uncomplicated GERD with no previous history of gastric surgery.
