Abstract:
Objective To differentiate colorectal sessile serrated adenoma(SSA)and large hyperplastic polyp(HP)with white light endoscopy and narrow band imaging. Methods Retrospective analysis was performed on the clinical data of 953 patients who underwent endoscopic screening for colorectal cancer at digestive endoscopy center of Peking Union Medical College Hospital from January 2015 to December 2015.Endoscopic features were compared with white light endoscopy and narrow band imaging between SSA and large HP in location, size, Paris classification, surface mucus, NICE classification and varicose microvascular vessel(VMV). Results A total of 28(2.9%)SSAs and 25(2.6%)HPs of diameter not less than 0.5 cm were detected in the total of 953 patients.Statistically significant difference was found in right hemi-colon, diameter not less than 1.0 cm and VMV in two groups(P<0.05). The sensitivities of the above three markers for SSA were 89.3%, 67.9% and 46.4% respectively. The specificities were 64.0%,76.0% and 84.0% respectively. Diagnostic accuracies were 77.4%,71.7% and 64.2% respectively. And the sensitivity, specificity and accuracy of three markers combined(at least two markers)were 75.0%, 88.0% and 81.1%, respectively. Conclusion SSA and large HP could be differentiated with a systemic consideration of lesion location, size, and surface of microvessels by using white light endoscopy and image-enhanced technique.
