Comparison of Cold and Hot Loop Resection Techniques for the Removal of Medium-sized Benign Colon Tumors

Widespread introduction of high-resolution videocolonoscopy into clinical practice has led to an increase in the detection of epithelial lesions of the colon, a significant portion of which are small (\<10 mm) and miniature (≤5 mm) lesions. According to the literature, 15.6-27% of colon lesions 6-9 mm in size and 4.4-10% of those ≤5 mm are high-risk lesions, i.e. they contain villous structures, foci of severe dysplasia or cancer. One of the methods for removing such lesions is the technique of cold loop polypectomy (CLP), i.e. mechanical removal of the polyp with a loop without the use of electric current. This method is common for colon lesions 4-9 mm in size. (For smaller lesions, a technically simple and effective method of removing them using biopsy forceps is most often used) Jung YS, Park JH, Kim HJ et al.
