“…A 2007 status report by the American Society for Gastrointestinal Endoscopy reviewed polypectomy devices, addressing the function and standards of available snare technology. 20 In the report, methodology, efficacy, and safety were reviewed. An analysis of the use of monofilament or braided snare, their gauges, and their shapes has been limited.…”

“…Many manufacturers have numerous snare products with the main difference being the size of the open loop, which can be as large as 3 Â 6 cm for some ''jumbo'' snares. 7 Some snares are rotatable, which may simplify orientation of the loop to the target. Specialized polypectomy snares (crescent, barbed, hexagonal) find application in tissue removal, but probably do not have a significant advantage when used for retrieval.…”

“…It is possible to perform polypectomy and EMR without hospitalization. However, patients occasionally experience complications such as bleeding and perforation after ER, even when small lesions are resected [3][4][5][6][7][8]. Cold snare polypectomy for colorectal lesions smaller than 10 mm has recently been reported to be safe and effective, but it is controversial for lesions larger than 10 mm [9].…”

Background: Monopolar instruments are generally used in colorectal endoscopic mucosal resection (EMR). Bipolar instruments have previously been reported to be as safe as monopolar instruments. We sought to compare the safety of the monopolar and bipolar snare and hemostatic forceps in an animal model. Methods: We created 5-mm, 10-mm, and 15-mm target lesions on an ex vivo porcine rectum. Two lesions of each size were resected via monopolar polypectomy (M-P), monopolar EMR (M-E), bipolar polypectomy (B-P), and bipolar EMR (B-E). We performed a pathological evaluation of the conditions of perforation and the effects of burning on the tissues. In addition, we burned the muscularis propria covered with submucosal layer using monopolar and bipolar hemostatic forceps and performed pathological evaluations. Results: Polypectomy and EMR were performed in a total of 24 target lesions. A perforation was found on histology in one case of M-P and one case of M-E after removing target lesions of 15 mm in diameter. There were no perforations during endoscopic resection using the bipolar snare. The thermal denaturation in B-P did not reach the muscularis propria layer regardless of the size of the target lesion. Although thermal damage after using monopolar hemostatic forceps was extensive, thermal denaturation was only seen on the surface of the submucosal layer when bipolar hemostatic forceps were used. Conclusions: Bipolar instruments cause less damage to the tissue than monopolar instruments. Our results also suggest that bipolar instruments may be safer than monopolar instruments in endoscopic procedures for colorectal lesions.
