ENDOSCOPIC SUBMUCOSAL DISSECTION (ESD) for a lesion spreading across the pylorus is extremely difficult because ESD on the duodenum side requires reversing the endoscope in the duodenal bulb, and countertraction cannot be applied during dissection of the pylorus. Various traction methods for ESD are reported to expand the field of view and increase dissection efficiency. We report the usefulness of the clip-with-

夹线牵引法可以有效地对扩散到幽门环的早期胃癌进行内窥镜黏膜下剥离

内窥镜黏膜下剥离术 (ESD) 对扩散到幽门的病变极为困难，因为十二指肠侧的 ESD 需要反转十二指肠球部内的内窥镜，并且在剥离幽门时不能应用反牵引。据报道，ESD 的各种牵引方法可以扩大视野并提高解剖效率。我们报告了剪辑的用处-
