Early diagnosis and treatment of early-stage gastrointestinal cancer can significantly improve the prognosis of patients, but the detection rate of this disease in China is still very low. Therefore, how to improve the detection rate of early-stage gastrointestinal cancer is a major challenge at present. The Objective of this article is to explore the status quo and prospect of the application of magnifying chromoendoscopy in the diagnosis and treatment of early-stage gastrointestinal cancer. The combination of electronic staining, optical staining, and magnifying technology can identify the abnormality of gastric mucosa microstructure and microvessel, clarify the nature and progression of the lesion, and point out the direction of accurate targeted biopsy. The combination of magnifying endoscopy diagnosis and pathological examination can provide greater help than the individual techniques for improving the precise examination of digestive endoscopy and the diagnosis and treatment of early-stage gastrointestinal cancer in China.
