Abstract:
Objective To evaluate necessity of colonoscopy in symptomatic subjects with colorectal neoplasia screening score.Methods Data of consecutive patients who underwent routine colonoscopy between October 2015 and December 2015 were prospectively collected.APCS score and HKCS score were used to evaluate the detection rate of colorectal tumors in groups of different risks and to predict the necessity of colonoscopy in symptomatic subjects.Results There were 815 subjects with mean age of 51.2± 14.8 years.Colorectal neoplasia and advanced neoplasia were identified in 170 (20.9％) and 43 (5.3％) cases.APCS score was classified as average risk (AR),moderate risk (MR) and high risk (HR),which included 234,400 and 161 cases,respectively.The detection rates of colorectal neoplasia in AR,MR and HR groups were 9.5％,20.0％ and 41.0％,respectively,and those of advanced neoplasia were 0％,5.5％ and 13.0％,respectively.Detection rate of colorectal neoplasia in the HR group showed 6.7 times of that in the AR group (95％CI:3.9-11.2).HKCS score was classified as AR and HR,which included 633 and 182 cases in the present study.The detection rates of colorectal neoplasia in these groups were 16.3％ and 36.8％,and those of advanced neoplasia were 3.2％ and 12.6％.Detection rate of colorectal neoplasia in HR group was 3.0 times of that in AR group (95％CI:2.1-4.3).Conclusion APCS score and HKCS score are both suitable for evaluating the necessity of colonoscopy in symptomatic subjects.It is necessary for HR patients to undergo colonoscopy to detect colorectal neoplasia,however,AR patients evaluated by APCS score can delay colonoscopy to economize medical resources and avoid unnecessary complications.
