Abstract

Abstract:

Objective

To explore whether the detection rate of colonoscopic polyps increases with the increase of learning time of colonoscopy.

Methods

The detection rates of colorectal polyps in four experienced endoscopists A, B, C, D and two colonoscopy trainees E and F, from July 2016 to December 2018, were analyzed and compared retrospectively.

Results

The detection rates of polyps in doctors A, B, C, D, E and F were 43.8%(1107/2529), 31.8%(420/1322), 35.3% (619/1753), 25.2%(194/771), 42.8%(166/388) and 29.3%(129/440), respectively.There were significant differences in the detection rates of polyps among 6 endoscopists, 4 experienced endoscopists and 2 colonoscopy trainees (all the P values were 0.000). The detection rates of polyps in colonoscopy trainees E were 48.39%(15/31), 42.86%(42/98) and 42.08%(109/259) every half year, and the data of colonoscopy trainees E were 21.84%(19/87), 32.73%(36/110) and 30.45%(74/243) respectively, which were no differences in the detection rates of polyps .

Conclusion

The detection rate of colonoscopic polyps does not increase with the learning time of colonoscopy.

Key words: Colonoscopy, Learning Time, Polyp Detection Rate
