Summary
Small colon polyps which are found during colonoscopy insertion are sometimes difficult to find during withdrawal and thus missed. The investigators aim to evaluate the differences of colon polyp/adenoma detection rates of patients undergoing additional inspection and polypectomy during insertion as compared to the patients undergoing traditional practice of careful inspection and polypectomy performed entirely during withdrawal of colonoscopy.
