Background/Aims: Endoscopic resection of all colorectal adenomatous lesions with a low complication rate, simplicity, and negativeresiduals is challenging. Hence, we developed a new method called “non-injection resection using bipolar soft coagulation mode(NIRBS)” method, adapted for colorectal lesions. In addition, we evaluated the effectiveness of this method. Methods: We performed NIRBS throughout a 12-month period for all colorectal lesions which snare resection was acceptable withoutcancerous lesions infiltrating deeper than the submucosal layer. Results: A total of 746 resected lesions were included in the study, with a 4.5 mm mean size (range, 1–35 mm). The major pathologicalbreakdowns were as follows: 64.3% (480/746) were adenomas, and 5.0% (37/746) were intraepithelial adenocarcinomas (Tis lesions). Noresiduals were observed in any of the 37 Tis lesions (mean size, 15.3 mm). Adverse events included bleeding (0.4%) but no perforation. Conclusions: NIRBS allowed the resection of multiple lesions with simplicity because of the non-injection and without perforating dueto the minimal burn effect of the bipolar snare set in the soft coagulation mode. Therefore, NIRBS can be used to resect adenomatouslesions easily, including Tis lesions, from small to large lesions without leaving residuals.
