Abstract：Objective To compare the application value of two endoscopic treatment methods,cold snare polypectomy(CSP)and hot snare polypectomy(HSP),in the resection of small colorectal polyps in elderly patients treated with oral anticoagulants.Methods Between January 2013 and June 2018,90 elderly patients with endoscopic treatment of colorectal polyps at the endoscopy center were selected and randomly divided into the CSP group and the HSP group,with 45 cases per group.Among the eligible patients,58 and 62 polyps were removed by the CSP and the HSP,respectively.The time of single polyp resection(preparation to complete resection),complete resection rate,intraoperative and postoperative bleeding,and 1-year recurrence of the two groups were compared and analyzed.Results There were no significant differences in the polyp size and complete resection rate between the two groups(P＞0.05).The resection time in the CSP group was significantly shorter than that of the HSP group(P＜0.05).The intraoperative bleeding rate in the CSP group was comparable to that of the HSP group(3.45％[2/58]vs 1.61％[1/62],P＞0.05).The delayed bleeding rate in the CSP group was significantly lower than that of the HSP group(1.72％[1/58]vs 12.90％[8/62],P＜0.05).There were no cases of delayed perforation in both groups.There was no significant difference in the length of stay between groups(P＞0.05).The 1-year recurrent rate was significantly lower in the CSP group than that of HSP group(1.72％[1/58]vs 6.45％[4/62],P＜0.05).The treatment cost of the CSP group was significantly lower than that of the HSP group(P＜0.05).The 1-year recurrent rate of colon polyps in the CSP group was significantly lower than that of the HSP group(P＜0.05).During the 1-year follow-up,there were no significant differences in abdominal symptoms,abdominal pain,and unformed stool between the two groups(P＞0.05).Conclusion CSP has the advantages of precise effect,high safety,rapid procedures and less trauma in the resection of small colorectal polyps in elderly patients treated with anticoagulants,which is worthy of clinical promotion.
