- W2124344539 abstract "Background: The polyp detection rates are regarded as a quality indicator of colonoscopy. The colonoscopic withdrawal time has been elucidated to be highly associated with polyp detectability. However, the variation in detectability of other lesions has not been sufficiently investigated. Colonic diverticula are depressed lesions entirely contrary to polyps. They are more likely to be missed by colonoscopy, while have sometimes more clinical importance than polyps. Objectives: To investigate the association between colorectal diverticula detection rates and colonoscopic withdrawal times in the examinations by trainee colonoscopists for Japanese patients. Methods: Procedural data performed at The University of Tokyo Hospital were reviewed. Thirteen trainee colonoscopists were characterized by their mean withdrawal time for normal colon. The diverticula detection rates were investigated in association with withdrawal times of colonoscopists. Results: Overall, 2,314 colonoscopies were reviewed. Mean withdrawal time ranged from 6.5min to 10.4min among colonoscopists. Colonic diverticula were detected in 29% and diverticulum detection rates varied from 21% to 43%. Withdrawal time and diverticulum detection rate showed a marginal association (p = 0.058). When stratified by the use of transparent hood, a strong association was shown in the examinations without hood (p = 0.009), while no association was found with hood attachment. Conclusion: Without hood attachment, the diverticula detection rates were associated with colonoscopic withdrawal times. The association became obscure by hood attachment." @default.
