A randomized controlled trial of cold snare polyppectomy and hot snare polypectomy for colorectal 4-9 mm polyps
Abstract
Objective \nTo compare the efficacy and safety of cold snare polyppectomy (CPS) and hot snare polypectomy (HSP) on 4 to 9 mm colorectal polyps. \n \n \nMethods \nA total of 365 patients, with 4 to 9 mm polyps, detected in the First Affiliated Hospital of Henan University of Science and Technology from June 2017 to June 2018 were selected and divided into CSP group (192 patients, 267 polyps) and HSP group (173 patients, 225 polyps) by random number table method. And the two groups were treated by CSP and HSP correspondingly. The complete resection rate, specimen retrieval rate, complications, hemoclip applications rate, abdominal discomfort rate, the time cost of average polyppectomy, pathological examination results were compared between the two groups. \n \n \nResults \nThe resection time for one polyp in CSP group was less than that of HSP group (P 0.05). \n \n \nConclusions \nCSP, in the comparison to HSP, is an effective and safe method that shortens the polypectomy duration in 4 to 9 mm polyps. \n \n \nKey words: \nColonic Polyps;\xa0Polypectomy;\xa0Cold snare;\xa0Hot snare
