Results

A total of 34 patients with colorectal neoplasms measuring 20-50 mm scheduled for ESD were enrolled. TBEC was performed at each mucosal defect after ESD. TBEC yielded a 100% (95%CI 89.8%-100%) complete closure rate, with a median (interquartile range [IQR]) closure time of 14.5 (12.9) minutes. The median (IQR) number of clips used was 10 (3.3). One case of delayed bleeding and one of post-ESD coagulation syndrome (both 2.9% [95%CI 0.5%-14.9%]) occurred following TBEC.

Baseline Characteristics

A total of 80 patients underwent colorectal ESD from June 2022 to March 2023, of whom34were finally enrolled.
Moreover, the safety analysis, full analysis, and per-protocol set seach consisted of all 34 patients.
The median (IQR) tumor diameter was 29.0 (10.3) mm.

Participant flow

This multicenter prospective single-arm pilot study was conducted at three institutions from June 2022 to March 2023. A total of 34 patients with colorectal neoplasms measuring 20-50 mm scheduled for ESD were enrolled. TBEC was performed at each mucosal defect after ESD.

Adverse events

One case of delayed bleeding and one of post-ESD coagulation syndrome occurred following TBEC.

Outcome measures

The primary outcome was the complete closure rate by TBEC. Secondary outcomes included the number of clips used, procedure time, and adverse events (AEs).
