Esophageal Endoscopic Submucosal Dissection Assisted by an Overtube with a Traction Forceps: An Animal Study

Figure 3

Submucosal dissection using an overtube with traction forceps (ESD). (a) The circumferential mucosal incision for the target lesion was completed. (b) The target lesion was grasped with the forceps and pulled to the luminal side, enabling the dissection plane to be clearly visualized. (c) Under adequate tissue traction, the submucosal dissection was performed using an IT knife. (d) The ESD procedure was completed as en bloc resection.
