Endoscopic anti-reflux therapy for gastroesophageal reflux disease

摘要

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,antireflux 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.
