- Abstract: Objective To explore the clinical efficacy of endoscopic electrocoagulation resection and cold resection techniques in the treatment of elderly patients with complex colonic polyps.Methods A retrospective selection was made of 100 elderly patients with colonic polyps who underwent endoscopic electrocoagulation resection and cold resection of colonic polyps in the Department of Gastroenterology of Yiwu Central Hospital from August 2021 to August 2023.According to the different surgical methods,the patients were divided into the electrocoagulation group(50 cases)and the cold resection group(50 cases).The polyp resection status,intraoperative and postoperative treatment conditions,postoperative pain degree,gastrointestinal quality of life index(GIQLI)score,length of hospital stay,total treatment cost,and recurrence situation after 1-year follow-up of the elderly patients with colonic polyps in the two groups were statistically analyzed.Results 108 polyps were resected in the electrocoagulation group and 113 in the cold resection group.The complete resection rate of polyps in the cold resection group was higher than that in the electrocoagulation group,the specimen damage rate was lower than that in the electrocoagulation group,the differences were statistically significant(P<0.05).There were no statistically significant difference in the average number of polyps removed and the recovery rate of polyp specimens between the two groups(P>0.05).The operation time and hospital stay of the cold resection group were shorter than those of the electrocoagulation group,the total treatment cost was less than that of the electrocoagulation group,and the usage rate of titanium clips during the operation was lower than that of the electrocoagulation group.The differences were all statistically significant(P<0.05).The incidences of intraoperative bleeding,delayed bleeding,perforation and abdominal pain in the electrocoagulation group were 6.00%,2.00%,2.00%and 6.00%respectively,which were higher than those in the cold resection group(2.00%,0.00%,0.00%and 2.00%),and there was statistically significant difference in the total incidence of complications between the two groups of patients(P<0.05).The visual analogue scale(VAS)scores of the cold resection group at 24 and 48 h after surgery were lower than those of the electrocoagulation group,and the differences were statistically significant(P<0.05).The GIQLI score of the cold resection group 3 months after the operation was higher than that of the electrocoagulation group,and the difference was statistically significant(P<0.05).The recurrence rate of the cold resection group at 1 year was lower than that of the electrocoagulation group,but the difference was not statistically significant(P>0.05).Conclusion The clinical efficacy of endoscopic cold resection technique in the treatment of elderly complex colonic polyps patients is better than that of electrocoagulation resection,and it has high safety and low treatment cost.It is worthy of clinical promotion and application.
