Abstract:In recent years, the incidence and mortality of digestive tract tumors in China remain high. Endoscopy is an important method for the diagnosis and treatment of digestive tract diseases, especially in the screening stage of early cancer precancerous lesions. However, the detection rate of early precancerous lesions under endoscopy is low. It is important to improve the diagnosis rate of early cancer under endoscopy for improving the prognosis of patients with digestive tract cancer. With the continuous improvement of computer technology and the arrival of the era of big data, the research of artificial intelligence technology assisted endoscopic disease diagnosis has also developed vigorously. In this paper, the diagnosis of gastrointestinal diseases under gastroscopy based on artificial intelligence technology is reviewed with reference to literatures at home and abroad.
