Abstract:
Objective To evaluate the value of near focus narrow-band imaging ( NF-NBI ) in differentiating hyperplastic polyp ( HP ) and sessile serrated adenomas/polyp ( SSA/P ) . Methods Data of 65 cases of pathologically confirmed HP or SSA/P with clear NF-NBI images in Huadong Hospital Affiliated to Fudan University from October 2017 to September 2018 were retrospectively analyzed. Three senior doctors observed the images of NF-NBI, including expanded crypt opening ( ECO ) and thick & branched vessel ( TBV) . The results were compared with pathological results in order to analyze differential diagnostic value of ECO and TBV for HP and SSA/P. Results Among 65 lesions, 44 were SSA/P and 21 were HP. The sensitivity, specificity, and accuracy of ECO, TBV, and ECO combined with TBV for differential diagnosis between HP and SSA/P were 80. 3％( 106/132 ) , 85. 7％( 54/63 ) and 82. 1％( 160/195 ); 38. 6％( 51/132) , 82. 5％( 52/63 ) , and 52. 8％( 103/195 ); and 84. 8％( 112/132 ) , 73. 0％( 46/63 ) , and 81. 0％(158/195), respectively. Conclusion ECO under NF-NBI has a high sensitivity for diagnosis of SSA/P . ECO combined with TBV is helpful for differential diagnosis between HP and SSA/P .
