Proposal of surveillance endoscopy strategies after colorectal ESD.

First
Surveillance		 Second Surveillance
En bloc ESD with histological complete resection of benign tumors 1 3 years after ESD Interval adjustment based on the findings of the first surveillance endoscopy
Piecemeal ESD or histological incomplete resection of benign tumors 2 6 months after ESD One year after the first surveillance endoscopy
ESD of early colorectal cancer 3 3–6 months after ESD Repeat surveillance at 3–6-month intervals for 2–3 years
