Endocytoscopic microvasculature evaluation is a reliable new diagnostic method for XXXX (with video).

@entity1 @entity3 @entity1127 @entity14
BACKGROUND: We previously reported on the efficacy of endocytoscopic classification (EC-C). However, the correlation of the endocytoscopic vascular (EC-V) pattern with diagnoses was unclear. OBJECTIVE: To assess the diagnostic accuracy of the EC-V pattern for @entity14 . DESIGN: Retrospective. SETTING: A university hospital. @entity1 : @entity1 who underwent endocytoscopy between January 2010 and March  2013. INTERVENTION: We evaluated 198 consecutive lesions according to the EC-V pattern (EC-V1, obscure surface microvessels; EC-V2, clearly observed surface microvessels of a uniform caliber and arrangement; and EC-V3, dilated surface microvessels of a nonhomogeneous caliber or arrangement). MAIN OUTCOME MEASUREMENTS: The diagnostic accuracy for predicting @entity1127 and @entity3 were compared between the EC-V pattern and other modalities (narrow-band imaging, pit pattern, and EC-C). RESULTS: The sensitivity, specificity, and accuracy of the EC-V1 pattern for diagnosing @entity1127 were 95.5%, 99.4%, and 99.0%, respectively. The sensitivity, specificity, and accuracy of the EC-V3 pattern for diagnosing @entity3 were 74.6%, 97.2%, and 88.6%, respectively. The diagnostic accuracy of the EC-V pattern for predicting @entity1127 was comparable to the other modalities. For predicting @entity3 , the EC-V pattern was comparable to narrow-band imaging and pit pattern, although EC-C was slightly more accurate (P  = .04). In the substudy, the diagnosis time by using the EC-V pattern was shorter than that with the EC-C pattern (P  < .001). LIMITATIONS: A single-center, retrospective study. CONCLUSIONS: The EC-V pattern saved more time than the EC-C pattern and had a diagnostic ability comparable to that of other optical biopsy modalities.
