Colonoscopy provides imperfect protection against colorectal cancer and is operator dependent. Colonoscopies typically are poorly documented. We aimed to determine whether videorecording impacts short-term performance of colonoscopy.
We videorecorded routine colonoscopies by seven colonoscopists, with and without their awareness. Colonoscopy quality was measured by blinded assessment of inspection time and technique.
From pre- to post-awareness of videorecording, mean inspection time increased by 49% for all colonoscopies combined and increased significantly for four individual colonoscopists. The overall quality of mucosal inspection technique improved by 31% after awareness of videorecording.
Awareness of videorecording improved physician performance of colonoscopy. Further investigation of the role of videorecording in achieving sustained improvements in the quality performance of colonoscopy, including increases in adenoma detection, is warranted.
结肠镜检查对结直肠癌的预防效果并不完美，且其效果依赖于操作人员。结肠镜检查通常记录不充分。本研究旨在确定录像是否会影响结肠镜检查的短期效果。
我们对 7 名结肠镜医生进行了常规结肠镜检查的录像，录像过程中医生知晓或不知晓正在录像。通过对检查时间和技术的盲法评估来测量结肠镜检查质量。
从录像前到录像后，所有结肠镜检查的平均检查时间增加了 49%，其中 4 名医生的检查时间显著增加。录像后，黏膜检查技术的整体质量提高了 31%。
录像的知晓提高了医生结肠镜检查的操作水平。需要进一步研究录像在提高结肠镜检查质量表现（包括提高腺瘤检出率）方面的作用。
