About this trial

Without high diagnostic efficacy of endoscopic forceps biopsy (EFB) and with low diagnostic efficacy of narrow band imaging (NBI) in novice endoscopists and endoscopists of community hospitals in China, it is urgent to improve diagnostic efficacy for gastric cancerous lesions.The investigators will conduct a study to develop and validate a diagnostic model based on NBI for early gastric cancerous lesions under endoscopic observation.
