Esophageal squamous cell carcinoma (ESCC) is a deadly disease, partly because it is often diagnosed late in disease stage. An accurate early diagnosis by endoscopy could detect advanced carcinoma as well as curable dysplasia and early ESCC. This could save patients from incurable advanced malignancy. Important progress has been made in high-quality endoscopic diagnosis, including magnifying endoscopy, narrowband imaging, and other image enhancement, as well as in techniques in endoscopic resection. These emerging techniques will aid the early diagnosis of ESCC that lead to higher chance of curing the cancer.
