Abstract：Objective To investigate and analyze the risk factors for recurrence of elderly colon polyps treated with endoscopic mucosal resection(EMR).Methods A total of 115 elderly patients with colon polyps were included in the study for analysis.They were divided into two groups based on whether they had postoperative recurrence,namely the non-recurrence group and the recurrence group.Clinical characteristics,general information,and surgical related information of the patients were collected based on an electronic medical record system.Logistic multivariate regression and univariate analysis were used to identify the factors affecting colon polyp recurrence after EMR surgery.Results Among the 115 patients,29 cases relapsed,with a recurrence rate of 25.21%,and 86 cases(74.79%)did not relapse.Univariate analysis showed that there were statistically significant differences between the two groups in the types of colonic polyps,the number of polyps,BMI,gender,high-density lipoprotein,the proportion of adenomas,multiple sites,triglycerides,uric acid,type 2 diabetes,hypertension,non-alcoholic fatty liver disease,and age(P<0.05).There was no statistically significant difference in the location of polyps,drinking history,educational level,smoking history and family history between the two groups(P>0.05).Logistic multiple regression analysis showed that after EMR treatment for large colon polyps,the polyp type,polyp diameter BMI,Polyp location,hypertension,non-alcoholic fatty liver disease,and age are risk factors for recurrence(P<0.05).Conclusion For elderly patients with large colon polyps,although endoscopic mucosal resection is effective,there is a risk of recurrence,which includes risk factors such as polyp diameter,polyp type,and age.It is necessary to assess the patient's risk of recurrence,develop intervention measures,reduce the risk of recurrence,and ensure treatment effectiveness.
