Endoscopic full-thickness resection (EFTR) is emerging as an approach to resect gastric gastrointestinal stromal tumors originating from the muscularis propria layer (MP-GISTs) because several established endoscopic closure methods and tools have been developed. However, EFTR is performed difficultly due to three challenges: limited luminal insufflation and visualization, insufficient operating space, and inadequate exposure of cutting line. Therefore, we performed a novel method of clip- and snare-assisted EFTR (also named as m-EFTR or chen-EFTR) to resect a MP-GIST. This m-EFTR (chen-EFTR) provides a novel approach to resect MP-GISTs through providing distinct endoscopic visualization, adequate exposure of cutting line and sufficient operating space.
内镜全层切除术（EFTR）正逐渐成为一种切除起源于固有肌层的胃胃肠道间质瘤（MP-GISTs）的方法，因为已经开发出了几种成熟的内镜闭合方法和工具。然而，由于三个挑战，EFTR操作困难：管腔充气和可视化受限、操作空间不足以及切割线暴露不充分。因此，我们采用了一种新型的夹子和圈套器辅助EFTR方法（也称为m-EFTR或chen-EFTR）来切除MP-GIST。这种m-EFTR（chen-EFTR）通过提供清晰的内镜可视化、切割线的充分暴露和足够的操作空间，为切除MP-GIST提供了一种新方法。
