近年来，随着新型内镜诊断技术及图像优化技术的问世，消化道早期癌的检出率得到了进一步的提高，新型内镜治疗技术的出现及推广推动了消化道早期癌的微创治疗，但我国消化道早期癌的内镜诊治水平与发达国家之间仍存在一定的差距，本文以我国消化道早期癌内镜诊治现状为基础，就消化道早期癌的内镜诊治策略进行评述。

In recent years, with the advent of new endoscopic diagnostic techniques and image optimization technologies, early gastrointestinal cancer detection rate has been further improved, new endoscopic treatment technology promotes the emergence of minimally invasive treatment of early cancer of the digestive tract, but there is still a certain gap between developed countries and our country in endoscopic diagnosis and treatment of early cancer of the digestive tract.This paper is based on the current status of early endoscopic diagnosis and treatment of gastrointestinal cancer, and endoscopic diagnosis and treatment strategies of early cancer of the digestive tract are reviewed.
