Professor Jiang described the epidemiology, diagnostic methods, endoscopic monitoring and treatment of colorectal cancer. Professor Jiang believes that with the continuous improvement of people's living standard in our country and eating habits change, the incidence of colorectal cancer in China rate also increased year by year, so early colorectal cancer and precancerous lesions of endoscopic diagnosis and treatment in the diagnosis and treatment of gastrointestinal tumor also plays a more and more important role.
Diagnosis, Professor Jiang mentioned the magnifying colonoscopy technology combined with the gland orifice type (pit pattern, figure 1), determine the nature of the lesions, made the same height and pathological diagnosis.

Staining magnifying endoscopy combined with crystal violet staining (Figure 2) can effectively determine the depth of invasion and the nature of the lesion, so as to determine the endoscopic treatment plan. Professor Jiang stressed that attention should be paid to the diagnosis of flat lesions.
