Core Tip: Various traction devices have been developed for endoscopic submucosal dissection (ESD). However, few traction devices have been validated in large-scale studies thus far. The CONNECT-G trial was the first multicenter randomized controlled trial to compare conventional ESD with clip-with-line-assisted ESD for superficial gastric neoplasms. This study suggested that the effectiveness of traction devices in gastric ESD depends on the traction direction; in addition, the most optimal traction direction is vertical to the gastric wall.
