The development of endoscopic submucosal dissection (ESD) has enabled en bloc resection of lesions regardless of size and shape. However, ESD of colorectal tumors is technically difficult. Early stage colorectal tumors can be removed by endoscopic mucosal resection (EMR) but larger tumors may require piecemeal resection. Therefore, ESD with snaring has been proposed for more reliable EMR and easier ESD. This is a good option to fill the gap between EMR and ESD, and a good step to the introduction of full ESD.
内镜下黏膜下剥离术（ESD）的发展使得无论病变的大小和形状如何，均可进行整块切除。然而，结直肠肿瘤的ESD在技术上具有挑战性。早期结直肠肿瘤可通过内镜下黏膜切除术（EMR）切除，但较大的肿瘤可能需要分块切除。因此，已有人提出采用圈套器辅助ESD，以实现更可靠的EMR和更简便的ESD。这是填补EMR和ESD之间差距的良好选择，也是迈向全面ESD的良好一步。
