Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Name: Endoscopic submucosal dissection (ESD) with or without probe-based confocal laser endomicroscopy (pCLE)
Type: Device
Overall Status
The aim of this study is to evaluate the usefulness of pCLE (probe-based confocal laser endomicroscopy) compared with conventional chromoendoscopy (CE) for delineating the margin of early gastric cancer (EGC) with endoscopic submucosal dissection (ESD).
