Endoscopic treatment for gastroesophageal reflux disease (GERD) is of considerable interest and involves three primary approaches: endoscopic suturing, radiofrequency ablation, and injection of bulking agents into the area of the lower esophageal sphincter. Given that GERD is a benign disease, a reversible technique might have some advantage. At present, endoscopic suturing is the only commercially available technique that offers this feature. Early endoscopic suturing devices required multiple intubations and use of overtubes, which could limit the field of vision during suture placement. In this study, researchers evaluated the performance of the FDA-approved Endoscopic Suturing Device (ESD; Wilson-Cook Medical, Inc.), which is introduced…
