Endoscopic anti-reflux therapy for gastroesophageal reflux disease

Gastroesophageal reflux disease has an increasing incidence and prevalence worldwide. A significant proportion of patients have a suboptimal response to proton pump inhibitors or are unwilling to take lifelong medication due to concerns about long-term adverse effects. Endoscopic anti-reflux therapies offer a minimally invasive option for patients unwilling to undergo surgical treatment or take lifelong medication. The best candidates are those with a good response to proton pump inhibitors and without a significant sliding hiatal hernia. Transoral incisionless fundoplication and nonablative radiofrequency are the techniques with the largest body of evidence and that have been tested in several randomized clinical trials. Band-assisted ligation techniques, anti-reflux mucosectomy, anti-reflux mucosal ablation, and new plication devices have yielded promising results in recent noncontrolled studies. Nonetheless, the role of endoscopic procedures remains controversial due to limited long-term and comparative data, and no consensus exists in current clinical guidelines. This review provides an updated summary focused on the patient selection, technical details, clinical success, and safety of current and future endoscopic anti-reflux techniques.

Automated summary

Gastroesophageal reflux disease is on the rise globally, and for patients with suboptimal response to proton pump inhibitors or concerns about lifelong medication, endoscopic anti-reflux therapies provide a minimally invasive option. The most supported techniques are transoral incisionless fundoplication and nonablative radiofrequency, but the role of endoscopic procedures remains controversial due to limited data and lack of consensus in current clinical guidelines.
