Colonoscopy has been used largely as a diagnostic tool for a number of conditions like colorectal cancer and inflammatory bowel disease. However, colonoscopy has multiple complications like perforation, abdominal pain, hemorrhage and anesthesia risk. But, among all these, perforation is the most dangerous complication which can occur in immediately after colonoscopy (post-colonoscopy period), its risk is 0.1%. Studies between teaching hospitals and non teaching hospitals on colonoscopy are scarce. A study was conducted from January 2011 to December 2015 in teaching versus non teaching hospitals to study perforation rates. Almost 257,010 patients were included in the study. Univariate regression was carried out and multivariate regression module was used to analyze positive results. Teaching hospitals showed a higher perforation rate in comparison to non-teaching hospitals. These rates were higher in females who have dilatation of stricture and inflammatory bowel disease. This review paper encompasses the perforation rate and on subject that more research is needed to mitigate the risks.
