Core Tip

Core tip: In this study, delayed perforation occurred in 0.1% (7 cases) of 4943 early gastric cancer patients undergoing endoscopic submucosal dissection (ESD); 43% (3 cases) of these cases required emergency surgery. This study also showed that the gastric tube was an independent risk factor associated with delayed perforation. This study is significant because it clarified both the clinical management and risk factors of delayed perforation based on data from a large series of consecutive patients undergoing ESD. Endoscopists must be aware of not only the identified factors associated with delayed perforation, but also how to treat this complication effectively and promptly.
