【摘要】Objective To study the diagnostic value of NBI combined with magnification endoscopy using VS classification standard for early gastric carcinoma lesions.Methods A total of 100 patients with suspected early gastric cancer whose gastric mucosa showed roughness,erosion,abnormal colour or ulcer were collected from January 2013 to June 2014.The lesions were observed under white light endoscopy and then underwent biopsy.Observation and biopsy were conducted in the same location by NBI-ME with self contrast method 2 weeks later.Patients in group A underwent NBI-ME,then were diagnosed by VS classifi-cation standard.Patients in group B were diagnosed with white light endoscopy.The sensitivity,specificity, positive predictive value,negative predictive value and accuracy between group A and group B were com-pared.Results The sensitivity,specificity,positive predictive value,negative predictive value and accura-cy of white light endoscopy in the diagnosis of early gastric carcinoma lesions were 76.19% (16 /21 ), 45.57%(36 /79),27.12%(16 /59),87.80%(36 /41)and 52.00%(52 /100),respectively;while the these variables of NBI-ME for
