ARTICLE HIGHLIGHTS
Research background
Missing diagnosis of sessile serrated lesions (SSLs), especially SSLs with dysplasia (SSL-D+s), is an important cause of interstitial colorectal cancer, and in this study, we hoped to find endoscopic features that have independent diagnostic value for SSL-D+s.
Research motivation
Previous studies on the endoscopic features of SSLs have focused on their differentiation from hyperplastic polyps and tubular adenomas, and comparisons of the endoscopic features of SSLs without dysplasia (SSL-D-s) and SSL-D+s have remained at the level of prediction of the sensitivity and specificity of individual endoscopic features. There have been several reports in the literature that SSL-D+s have a risk of faster progression to adenocarcinoma compared to SSL-D-s and conventional tubular adenomas. Therefore, it is important to look for endoscopic features that have independent predictive value for SSL-D+s and assist the endoscopist in making immediate diagnoses.
Research objectives
This study looks for endoscopic features that have independent diagnostic value for colorectal SSL-D+s. These features may help endoscopists to make immediate diagnoses during colonoscopy.
Research methods
In this study, endoscopic features potentially predictive of SSLs were first analyzed by univariate analysis, and then multivariate logistic regression analysis was performed to obtain endoscopic features with independent diagnostic value for predicting SSL-D+s and the diagnostic validity of these endoscopic features.
Research results
In univariate analysis, location, size, surface shape, color, microvascular varices, and crypt opening pattern of colorectal SSLs had value in predicting SSL-D+s. In multifactorial regression analysis, color, microvascular varices and crypt opening pattern had independent diagnostic value in predicting SSL-D+s.
Research conclusions
Reddish color, microvascular varicose, and mixed pattern of crypt openings are independent diagnostic features for colorectal SSL-D+s.
Research perspectives
This finding is expected to improve the immediate diagnostic accuracy of endoscopists in SSL-D+s in order to inform them to use appropriate endoscopic treatment modalities.
