 Endoscopic submucosal dissection(ESD)enables us to resect a whole lesion in an en-bloc fashion even if the size of the tumor is large. In case of superficial esophageal cancer, therapeutic strategies depend on the histological diagnosis. So ESD is useful in terms of less invasive than surgery and making a precise diagnosis. However the esophagus is located in the mediastinum, so it is easily affected by heart beating and respiratory movement. So ESD techniques there are more difficult to master than those in stomach cases. For safety, it is important to get a good view of the operating field and to keep countertraction in the dissecting layer during the procedure.
