Fig. 4From: A simple method for diagnosing gallbladder malignant tumors with subserosa invasion by endoscopic ultrasonographyComparison of the diagnostic accuracy of GBMTs with ss invasion between pancreaticobiliary EUS specialists and beginners. An irregular (thickened or narrow) LHEL was used to assess the diagnosability of GBMTs with ss invasion by three pancreaticobiliary EUS beginners (endoscopists a, b, and c) and specialists. The diagnostic accuracy of GBMTs with ss invasion was not significantly different between the specialists and beginners (specialists 93.9% vs beginners (Endoscopist A 83.7%, Endoscopist B 83.7%, and Endoscopist C 75.5%)). GBMT, gallbladder malignant tumor; ss, subserosa; EUS, endoscopic ultrasonography; LHEL, lateral hyperechoic layerBack to article page
