Abstract：Colonoscopy has long been considered the gold standard for evaluation of the colon.Unfortunately,time has shown that colonoscopy may be a flawed gold standard,as lesions may be missed and carcinomas may not be prevented.In this brief review,we conclude the operation methods to reduce the rate of missed diagnosis of colonoscopy,including the 6-min withdrawal time,proper bowel preparation,experience of the endoscopist,use of a transparent cap.We also summarize novel approaches for improving colorectal neoplasm detection rate,such as chromoendoscopy,narrow band imaging(NBI),the flexible spectral imaging color enhancement (FICE),i-scan and so on.New endoscopic instruments,such as wide-angle colonoscope,retroview colonoscope,third-eye retroscope(TER),330°full view colonoscope are explored to help clinical work and reduce the missed rate in the largest extent.
