Core Tip

Core tip: Although colonoscopy-related adverse events rarely occur and the need for colonoscopy is increasing, the proportion of subjects with risk factors is increasing. Recently, the perforation rate, as reported in large studies, ranges from 0.005-0.085%. The perforation probability after colonoscopy does not decrease over time in either the West or the East. Other studies have reported post-colonoscopy bleeding occurring in 0.001-0.687% of cases. In this review article, we discuss the current trends in post-colonoscopy complications, as well as the challenges to be addressed through future research.
