Proper early detection of GI lesions is the key factor for improving patients' prognosis and improving quality of care. It is our duty as a gastroenterologist offering endoscopic screening and diagnostic services to do the best for our patients care. In clinical studies, IEE outperformed conventional white-light endoscopy in diagnosing lesions and identifying their morphologies. Large-scale studies on various lesions for standardization of findings and training are needed. It is also hoped that every center could adopt the technology of IEE for better outcomes and quality.
