Upper gastrointestinal endoscopy (UGE) is currently recommended in cirrhotic patients to detect the presence of esophageal varices (EV). Spleen stiffness measurement (SSM) with FibroScan has been used for this purpose, showing variable sensitivity (S) and specificity (Sp). The aim of this study was to evaluate the capability of SSM to detect the presence and size of EV in cirrhotic patients in comparison to other noninvasive modalities. Sixty-six patients with cirrhosis who had undergone UGE in the previous 6 months underwent SSM and liver stiffness measurement (LSM) using FibroScan. Biochemical parameters and ultrasonography data were also collected to calculate other noninvasive indexes. Valid spleen stiffness measurements were obtained for 60 of the 66 patients initially included in the study (90.1%). In the multivariate analysis only splenomegaly and SSM were predictive of esophageal varices. SSM was the most accurate diagnostic tool, obtaining an area under the ROC curve of 0.8 for values below 48 KPascals, with S = 87%, Sp = 69%, and 76.7% of successfully diagnosed patients. SSM with FibroScan was significantly higher for cirrhotic patients with EV. Our study suggests that spleen stiffness may be useful to identify cirrhotic patients at risk of having EV, although further studies are needed.
