Aims We aim to evaluate endoscopic ultrasound share-wave elastography of the liver to
predict liver cirrhosis.
Methods A single-center, diagnostic cohort study. Consecutive patients with history of chronic
liver disease were evaluated with a EUS share wave elastography of the right and left
hepatic lobes. Patients without a history of any medical condition despite subepithelial
lesions were included as control. A transient elastography measurement of the liver
was performed in both study and control patients in order to evaluate for correlation
between elastography measurements. We calculated the overall accuracy of EUS- share
wave elastography of the liver in the prediction of liver cirrhosis. Statistical analysis
was performed on R v.3.6.0.
Results Among the 28 patients included, 14 had cirrhosis of the liver. The median age was
65.5 years, 64.3 % were female. 92.9 % of cirrhotic cases had a Child-Pugh A. The
EUS share-wave elastography of the right hepatic lobe has a direct, proportional,
and significant correlation (r=0.693 [95 % CI 0.431 – 0.847; p < 0.001]) as well as
with the EUS share-wave of the left hepatic lobe (r=0.460 [95 % CI 0.105 – 0.711;
p = 0.014]). The EUS-share wave of the right and left hepatic lobe reached an area
under the receiver operating characteristics curve (AUROC) of 0.98 and 0.96, respectively.
For identification of patients with cirrhosis, the EUS share-wave elastography of
the right hepatic lobe with a cut-off value of ≥10.7 kPa had a sensitivity, specificity,
PPV, and NPV of 100 %, 93 %, 93 %, 100 %, respectively. In the left hepatic lobe using
a cut-off value of ≥14.0 kPa, EUS-share wave had a sensitivity, specificity, PPV,
and NPV of 93 %, 93 %, 93 %, 93 %, respectively.
Conclusions EUS-share wave of the liver accurately diagnoses patients with liver cirrhosis. EUS-share
wave of the right and left hepatic lobe correlates with transient elastography measurements
of the liver. Larger studies are necessary to validate these data.
