Number of participants that the trial has enrolled 119
Results
Among 137 neoplasms, SOUTEN-ESD was completed in all cases. No cases required conversion to hybrid ESD or to a dedicated ESD device. The mean procedure time was about 26 minutes. The en-bloc resection rate was 100% and the R0 resection rate was 100%. The rate of perforation was 0%, the rate of delayed bleeding was 2.2%, and the rate of post-ESD coagulation syndrome (PECS) was 2.9%.

Baseline Characteristics
From October 2018 to January 2019, 119 consecutive patients were prospectively enrolled and treated by SOUTEN-ESD. 
Participant flow
Colorectal ESD was performed for 149 colorectal neoplasms at NTT Medical Center Tokyo and Omori Red Cross Hospital during the study period. We excluded 12 lesions (three lesions with huge polypoid growth, one lesion converging folds, four recurrent lesions after endoscopic treatment, and four lesions suspected of SM deeply invasive adenocarcinoma (SM deep invasion)) since we performed colorectal ESD with other knives. 
Adverse events
The rate of perforation was 0%, the rate of delayed bleeding was 2.2% (3/137), and the rate of PECS was 2.9% (4/137). 
Outcome measures
The rate of Failure of SOUTEN-ESD was 0% (The rate of complete SOUTEN-ESD was 100%).
