内镜粘膜下剥离术（ESD）最近已积极进行治疗浅表性食管癌，但是，很难确保一个良好的视野，粘膜剥离，该技术需要相当的技巧。我们已经开发了一种双通道ESD方法，使用内窥镜食管粘膜切除术（EEMR）管，使其能够在应用反牵引的同时以良好的视野进行粘膜下剥离。反牵引是通过操纵一个精细的抓钳插入通过侧通道的EEMR管，和粘膜下层剥离层的视野可以很容易地暴露。该技术可以在以稳定的视野持续观察粘膜下层剥离层的同时进行，并且还易于处理血管。此外，切开的粘膜不会干扰视野。
Endoscopic submucosal dissection (ESD) recently has been aggressively performed to treat superficial esophageal cancer; however, it is difficult to secure a good field of view for mucosal dissection, and the technique requires considerable skill. We have developed a double-channel ESD method using an endoscopic esophageal mucosal resection (EEMR) tube that makes it possible to perform the submucosal dissection with a good field of view while applying countertraction. Countertraction is achieved by maneuvering a fine grasping forceps inserted through the side channel of the EEMR tube, and the field of view of the submucosal dissection layer can be easily exposed. This technique can be performed while constantly observing the submucosal dissection layer with a stable field of view, and it is also easy to handle the blood vessels. Moreover, there is no disturbance of the field of view by the dissected mucosa.
