[HTML][HTML] Diagnostic efficacy of endoscopic ultrasound elastography in differentiating solid pancreatic lesions: a single-center experience
Clinical Endoscopy, 2019•synapse.koreamed.org
Methods The study had a retrospective design; it included 97 patients with SPLs and 19
patients with inflammatory lesions. The ES and SR were determined during the examination;
finally, EUS-guided fine needle aspiration was performed. Results In this 2-year study, 116
patients were enrolled (97 with malignant lesions and 19 with benign lesions). There were
69 men and 47 women. Their median age was 55.9 years. A cut-off point was detected at SR
of 7.75 with a specificity of 99.9%, sensitivity of 90.7%, positive predictive value (PPV) of …

Methods
The study had a retrospective design; it included 97 patients with SPLs and 19 patients with inflammatory lesions. The ES and SR were determined during the examination; finally, EUS-guided fine needle aspiration was performed.
Results
In this 2-year study, 116 patients were enrolled (97 with malignant lesions and 19 with benign lesions). There were 69 men and 47 women. Their median age was 55.9 years. A cut-off point was detected at SR of 7.75 with a specificity of 99.9%, sensitivity of 90.7%, positive predictive value (PPV) of 99.9%, negative predictive value (NPV) of 67.9%, and accuracy of 92.2%. After adding the ES to the SR, the cut-off point at 7.75 resulted in a specificity of 94.6%, sensitivity of 99%, PPV of 98%, NPV of 98.5%, and accuracy of 97%.
Conclusions
The use of the ES combined with the SR increases the accuracy of differentiation between benign and malignant SPLs and is an effective method for the evaluation of pancreatic masses.
