Number of participants that the trial has enrolled

80

Results

CS-EMR failed in 11 lesions (13.8%), all of which were resected using high-frequency electric current. En bloc resection rate by CS-EMR and histological complete resection rate by CS-EMR were 82.5% (66/80) and 63.8% (51/80), respectively.

Of all 80 lesions, white protrusion within the mucosal defect, and submucosal layer in the resected specimens were found in 43 (53.8%), and 20 lesions (25.0%), respectively.

Baseline Characteristics

72 patients with 80 polyps were included. The median patient age was 68.5 years. 47 (65.3%) were men and 12 (16.7%) took antithrombotic drugs.
The median size of polyps was 12 mm. Most polyps (63.8%) were located at the right colon, 56.3% had a slightly elevated morphology.

Participant flow

During the study period, 75 patients were assessed for eligibility, and 3 were excluded because 2 patients met the exclusion criteria and one polyp in the other patient was diagnosed as non-neoplastic lesion prior to CS-EMR.

Adverse events

No immediate bleeding occurred during the CS-EMR procedure.
No serious adverse events occurred.
Minor postprocedural bleeding was observed in 12 patients (16.7%). Seven patients (9.7%) complained of abdominal symptoms,

Outcome measures

The primary outcome was histological complete resection rate by CS-EMR, which was defined as en bloc resection, pathologically negative vertical margin, and no neoplastic tissue obtained from four quadrants of the mucosal defect margin. The secondary outcomes were en bloc resection rate by CS-EMR; failure rate of CS-EMR; the incidence of adverse events such as immediate bleeding, delayed bleeding, delayed perforation, minor postprocedural bleeding, and abdominal symptoms; the presence of white protrusions within the mucosal defect; and the presence of a submucosal layer and muscularis mucosal layer in the resected specimens.
