Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) has emerged as a standard and convenient method for the sampling of subepithelial lesions (SELs). Immunohistological analysis is required to definitively distinguish mesenchymal tumors; however, EUS-FNA provides insufficient material to achieve this, especially for small SELs < 2 cm. We therefore previously reported a novel submucosal tunneling biopsy (STB) technique that utilizes endoscopic submucosal dissection (ESD) for sampling SELs. However, unresolved advanced technical issues have hindered its widespread application. Currently, a counter-traction technique is used to facilitate ESD. We here describe a technically simplified STB technique using clip-with-line traction for gastric SELs.
内镜超声（EUS）引导下细针穿刺抽吸（FNA）已成为一种用于上皮下病变（SELs）采样的标准且便捷的方法。明确区分间叶性肿瘤需要进行免疫组织学分析；然而，EUS-FNA提供的材料不足以实现这一点，尤其是对于小于2 cm的小SELs。因此，我们之前报道了一种新型的黏膜下隧道活检（STB）技术，该技术利用内镜黏膜下剥离术（ESD）对SELs进行采样。然而，尚未解决的先进技术问题阻碍了其广泛应用。目前，一种反向牵引技术被用于促进ESD。我们在此描述一种技术简化的STB技术，该技术使用带线夹子牵引来处理胃SELs。
