Analysis Of The Polyp Detection Rate By Opportunistic Screening Colonoscopy Among Different Populations At Different Periods

Objective:By retrospectively analyzing the clinical case information of the subjects who received colonoscopy,the detection rate of colon polyps in the high-risk population and the general population at different stages of colonoscopy was discussed,so as to improve the awareness of the population for routine colonoscopy physical examination.Methods:The electronic colonoscopy reports of patients undergoing colonoscopy in the Endoscopy Center,Cancer Hospital Affiliated to Shanxi Medical University from January 2000 to December 2004 and from January 2014 to December 2019 were retrospectively analyzed,and the differences in the detection rate of colon polyps at different stages in terms of age and gender and the changes in the detection rate were analyzed.Results:From January 2000 to December 2004,the detection rate of colon polyps in high-risk population was 48.32%,and the detection rate of colon polyps in general population was 33.67%.From January 2014 to December 2019,the detection rate of colon polyps in high-risk population was 62.30%,and the detection rate of colon polyps in general population was 57.84%.There was a significant difference in the detection rate of colon polyps between the general population and the high-risk population in different periods(P<0.01).The detection rate of colonic polyps in male subjects was60.82%,and that in female subjects was 44.87%.The difference in the detection rate of colonic polyps among different genders was highly statistically significant(P<0.01).In the general population and high-risk population,the detection rate of colon polyps in males was significantly higher than that in females at different periods,and the difference was highly statistically significant(P<0.01).From January 2000 to December 2004,and from January 2014 to December 2019,the detection rate of colon polyps in different populations and different age groups had high statistical significance(P<0.01).From January 2014 to December 2019,there was a small difference in the detection rate between high-risk population and general population in the same age group.From January 2014 to December 2019,the detection rate of colon polyps in high-risk population and general population aged 40 to 45 years old was 52.94% and 48.93%,respectively.From January 2000 to December 2004,the detection rate of colon polyps in high risk population with > aged 55 to 60 was 49.44%.Conclusion:The detection rate of colonic polyps is now significantly higher.From January 2000 to December 2004,the detection rate of colon polyps in high-risk population was significantly higher than that in general population and From January 2014 to December2019,the detection rate of colon polyps in high-risk groups was close to that of the general population.Should cause extensive attention of the society,so it is necessary to take colonoscopy as one of the routine physical examination items and people over the age of 40 should have colonoscopy regularly.
