Colonoscopy is one of the most useful procedures for making the diagnosis and treating various colorectal diseases, but this procedure rarely causes serious complications such as perforation. The incidence of colon perforation during colonoscopy is low. However, as the demand for screening and surveillance colonoscopy has gradually increased and colonoscopic polypectomy has become a commoner procedure in daily clinical practice, endoscopists should pay attention to prevent and manage colonoscopy-related perforation. The purpose of this review is to briefly summarize the guidelines from the World Journal of Emergency Surgery for the management of colonoscopy-related perforation.
