| Abstract: |
This article from a series on advances in endoscopy answers common clinical questions about colonoscopy withdrawal times and adenoma detection rates. The author discusses the main quality indicators for colonoscopy, recommendations for adenoma detection rates, the relationship between withdrawal times and adenoma detection rates, the role of other factors such as bowel preparation or the presence of advanced neoplasia in this context, and areas needing additional research. Research studies have shown that adenoma detection was strongly associated with longer withdrawal times: Endoscopists whose withdrawal times were more than 6 minutes detected more than twice as many patients with adenomas that were 1 centimeter or larger in size. The author reminds readers that withdrawal time is not the only factor involved, and improved research on other aspects, such as how well endoscopists are looking behind folds, how well they clean up, and the general quality of their bowel preparations, is needed. 5 references. |
