Abstract：Objective To explore the detection rate of adenoma during Pentax colonoscopy and the risk factors for postoperative polyp recurrence.Methods The general information and endoscopic test results of 900 subjects who underwent Pentax colonoscopy at the General Hospital of Hebi Coal Industry Group Co.,Ltd.from January 2022 to December 2024 were collected.The detection rate was calculated and they were divided into a detection group(109 cases)and a non-detection group(791 cases)based on whether adenomas were detected.The general information of the subjects in the two groups was compared.Analyze its independent influencing factors.The follow-up data of 109 patients who were first diagnosed with adenoma and underwent endoscopic resection after colonoscopy and histological examination in the same period were collected.According to the colonoscopy examination results during the follow-up,the patients were divided into a recurrence group(73 cases)and a non-recurrence group(36 cases).The general data of the two groups of patients were compared,and the risk factors and protective factors of postoperative polyp recurrence were analyzed.Results The detection rate of adenoma was 12.11%(109/900);The proportions of male subjects,those aged≥45 years,those with diabetes,chronic constipation,and intestinal preparation scores ranging from 7 to 9 in the detection group were higher than those in the non-detection group,while the proportion of anesthesia was lower than that in the non-detection group.The differences were statistically significant(P<0.05).The results of multivariate Logistic regression analysis showed that male gender,age≥45 years old,and intestinal preparation score of 7-9 were all independent influencing factors for the detection of adenoma during colonoscopy(P<0.05).The proportions of male patients,chronic constipation,and adenoma≥10 mm in the recurrence group were all higher than those in the non-recurrence group,and the proportions after a bowel preparation score of 7-9 was lower than that in the recurrence group,with statistically significant differences(P<0.05).The results of multivariate Logistic regression analysis showed that male gender and chronic constipation were risk factors for postoperative polyp recurrence(P<0.05),and a bowel preparation score of 7 to 9 was a protective factor for postoperative polyp recurrence(P<0.05).Conclusion Male gender,age≥45 years old,and a bowel preparation score of 7-9 will increase the detection rate of adenoma.Male gender and chronic constipation will increase the risk of postoperative polyp recurrence,while a bowel preparation score of 7-9 will reduce the risk of postoperative polyp recurrence.
