Description
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 doublechannel 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.
