A retrospective study ( n = 87) has compared both techniques for <10 mm lesions and ESD showed a trend to a better pathologically complete resection rate (95% vs. 83%, p = 0.17) and a trend to a higher adverse event rate (perforation 2.6% vs. 0%, delayed bleeding 5.1% vs. 4.2%), but with no statistically significant differences [ 20 ].
