Arms Assigned Interventions
Experimental: Hybrid knife
O-type Hybrid knife is used the whole ESD process except for minimum use of dual knife in border marking and initial mucosal cutting.
Device: Hybrid knife
Use Hybrid knife in ESD procedure
Active Comparator: IT knife
IT knife is used the whole ESD process except for minimum use of dual knife in border marking and initial mucosal cutting.
Device: IT knife
Use IT knife in ESD procedure.

Detailed Description:
Endoscopic submucosal dissection (ESD) has been accepted as an minimal invasive alternative to surgery for localized early upper gastrointestinal neoplasms recently. However, the procedure remains to be technically challenging and time consuming. Many modified methods or newly developed devices were developed to simplify the procedure. A new insulated tip dissecting knife (O-type Hybrid knife) has been recently developed with both injection and lateral cutting capability. The aim of this study was to investigate whether ESD procedure could be shortened with this new device.
