- ESE endoscopic submucosal excavation, STER submucosal tunneling endoscopic resection; aNo Significance; bIn one case, there were three lesions (≤ 15 mm), therefore the case number with lesion size ≤15 mm was 11, while the lesion number was 13; c In two cases, each had two lesions (> 15 mm), therefore the case number with lesion size > 15 mm was 29
