Core Tip

Core tip: This was a retrospective matched-pair analysis to evaluate the efficacy and safety of clip-and-snare method using pre-looping technique (CSM-PLT) for gastric endoscopic submucosal dissection (ESD). CSM-PLT is one of the traction methods that was developed to perform gastric ESD more effectively. Compared with conventional ESD, ESD using CSM-PLT had significantly shorter total procedure time (38.5 min vs 59.5 min, P = 0.023). With regard to proportion of en bloc resection and complications, there was no significant difference between the groups. Hence, CSM-PLT is a promising method for gastric ESD.
