Effect of cold snare endoscopic mucosal resection on clinical indicators and complications in patients with colon polyps
Objective To explore the effectiveness of cold snare endoscopic mucosal resection(CS-EMR)in patients with colon polyps.Methods Totally 113 patients with colon polyps admitted to the hospital from January 2022 to January 2023 were assigned to receive either hot snare endoscopic mucosal resection(HS-EMR,control group,n=56)or CS-EMR(observation group,n=57).The 1-year follow-up after discharge was performed to compare operation time,average number of polyps,hospitalization time,clinical indicators(complete resection rate[CRR],polyp removal time,recovery rate[RR]),serum prostaglandin E2(PGE2),nerve growth factor(NGF),visual analogue scale(VAS),incidence of complications.The recurrence rate of polyps during the 1-year follow-up was assessed.Results The difference was not statistically significant in the operation time,average number of polyps,hospitalization time,CRR,RR between groups(P＞0.05).After operation in awakening state,the observation group had significantly shorter polyp removal time,significantly lower PGE2,NGF and VAS than the control group(P＜0.05).During operation,the observation group presented significantly lower total incidence of immediate and delayed hemorrhage than the control group(P＜0.05).None of the recurrence rate of polyps differed significantly between groups during the 1-year follow-up(P＞0.05).Conclusion CS-EMR can improve the CRR and shorten polyp removal time in patients with colon polyps.It is simple,with little postoperative pain and complications.
