Aims: The reflux of duodeno-gastric contents into the remnant esophagus (gastric tube-esophageal reflux: GTER) is a significant issues in long-term esophageal cancer survivors after radical esophagectomy. We attempted endoscopic valve (funnel) creation for prevention for GTER using OverStitch endoscopic suturing system. Methods: The OverStitch was mounted onto a standard double-channel endoscope. Under general anesthesia, the funnel creation was attempted by placing semi-full thickness sutures on the gastric wall, at 3 cm distal to the primary esophago-gastric anastomosis. The postoperative outcomes were also evaluated. Results: In total, 4 sutures were needed and the operating time was 62 minutes without complication. The endoscopic and swallowing studies, as well as pH profile, were all improved postoperatively. The patient’s quality of life was dramatically improved with complete disappearance of night-time reflux in spine position. Conclusions: Endoscopic antireflux funnel creation was feasible and safe. This procedure may become a useful treatment for patients with severe GTER after esophagectomy.
