Colonoscopy and polypectomy are the most effective tools available to prevent colorectal cancer. The technical performance of colonoscopy can be improved by methods that make polyp detection easier and more reliable, facilitate cecal intubation, and reduce recurrence and complication rates after polypectomy. The state-of-the-art and possible future trends in patient preparation, indications, screening and surveillance intervals, sedation issues, and virtual colonoscopy are reviewed in this article.
