UNASSIGNED: Confocal laser endoscopy (CLE) diagnostic criteria for @entity1600 of @entity356 was established and evaluated to provide a basis for CLE clinical application in the diagnosis of @entity1600 . CLE scanning (surface scanning and sectional scanning) and pathology examination were conducted in @entity356 tissues and lymph nodes of 5 cases. Characteristics of lymphatic @entity3 in CLE imaging were observed and summarized in combination with pathology. The diagnostic criteria were corroborated in 124 lymph nodes of another 14 cases and CLE detection time needed for diagnosis was recorded. The CLE diagnostic criteria were tested and evaluated, and the effect of lymph node size on the diagnosis accuracy was determined. All the 19 @entity1 were confirmed as @entity356 . Sectional scanning can get comprehensive observation for internal structures of lymph nodes, in which abnormal large heterocyst appeared with special structural changes. CLE scanning could detect 88.75% of the positive @entity3 and 68.18% of the negative @entity3 examined by the pathology methods based on the established CLE diagnostic criteria. In comparison with pathological diagnosis, specificity, sensitivity and accuracy of CLE diagnosis were 88.75%, 68.18% and 81.45%, respectively. Accuracies of CLE diagnosis on the lymph nodes grouped by size were 85.29%, 77.78% and 88.89%, respectively, with no significant difference between groups (P > 0.05). Complete internal structures of lymph nodes can be observed clearly by CLE sectional scanning. The size of lymph nodes had no effects on diagnosis accuracy. CLE shows better sensitivity and specificity than traditional pathological diagnosis.
