ESD-P, endoscopic submucosal dissection of the postoperative stomach; ESD-N, endoscopic submucosal dissection of the non-operative stomach; SD, standard deviation; IQR, interquartile range
The p value was calculated using the χ2 test or Fisher exact test for categorical data
The p value was calculated using the Mann-Whitney U test for continuous data not normally distributed
