Core Tip
Core tip: The endoscopic mucosa-submucosa clip closure method is a simple closure method using only conventional clips. The success rate of the endoscopic mucosa-submucosa clip closure method was 68.2% (15/22) after gastric endoscopic submucosal dissection. The location and size of a mucosal defect were considered to be the main factors underlying difficulty in closure. Defects were relatively easy to close in the greater curvature of the upper or middle third stomach, because the gastric wall was relatively thin and soft and a front view approach could be taken.
