A comparative study of cold snare and hot snare resection of small colorectal polyps

Objective To compare the effect of cold snare and hot snare on the resection of small colorectal polyps, and to explore the clinical value of cold snare technique in removing colorectal polyps. Methods From September 1, 2017 to January 31, 2018, 206 cases of patients with colorectal polyp resection in the Department of Gastroenterology of Peking University International Hospital were studied. During this period, according to the standard, 103 cases of patients (158 polyps) were in the cold snare group, and 103 patients (180 polyps) were randomly selected as control group from patients of the hot snare group. The related clinical data were analyzed retrospectively. The location, shape, size, polypectomy time, pathological type, complete resection rate, specimen recovery rate, complications and related costs of the two groups of polyps were compared. Results The polypectomy time of the cold snare group was shorter than that of the hot snare group.The difference was statistically significant (Z=-11.727, P 0.05). Conclusions The operation time of cold snare technique in colorectal polyps (6-9 mm in diameter) is shorter and the cost is lower, which is worthy of clinical promotion.
