Core Tip

Core Tip: This systematic review and meta-analysis examined the diagnostic efficacy of each category of the Japan Narrow-band imaging Expert Team (JNET) and Pit pattern classifications for colorectal lesions. The pooled analyses of 19227 colorectal lesions from 31 studies were performed. The sensitivity, specificity, diagnostic odds ratio, and area under the summary receiver operating characteristic curve of each category of the JNET and Pit pattern classifications were calculated. The results suggest that the diagnostic efficacy of the JNET classification may be equivalent to that of the Pit pattern classification. However, due to its simpler and clearer clinical application, the JNET classification should be promoted for classification of colorectal lesions, and to guide the treatment strategy.
