Abstract: Objective To evaluate the efficacy of i-scan endoscopy in detecting small colorectal precancerous lesions.Methods A total of 127 patients were randomized into 2 groups to underwent conventional colonoscopy and i-scan endoscopy respectively.The findings were compared with pathologic examinations.Results A total of 84 lesions were detected by conventional endoscopy in 64 patients,while 147 lesions were found in 63 patients with high resolution detection only,which was increased to 259 with i-scan,including 102 flat lesions.With respect to histology,adenomatous lesions could be predicted with a high sensitivity (80％) and a high specificity ( 100％ ) by i-scan endoscopy.Conclusion More small colorectal lesions can be detected by i-scan endoscopy,which can distinguish neoplasm from non-neoplasm colorectal lesions.
