Background & Aims: Patients with cirrhosis and small hepatocellular carcinoma with normal bilirubin and hepatic venous pressure gradient (HVPG) <10 mm Hg have >70% 5-year survival after hepatic resection. On the contrary, patients with HVPG >= 10 mm Hg (clinically significant portal hypertension, CSPH) frequently develop decompensation following surgery, with around 50% 5-year survival. Liver stiffness (LS) evaluation by transient elastography might non-invasively identify CSPH. We investigated the usefulness of LS predicting CSPH in patients with compensated cirrhosis and potentially resectable liver tumors. Methods: Ninety-seven consecutive Child-Pugh A patients with potentially resectable liver tumors referred for HVPG measurement were prospectively evaluated. In fasting conditions LS was measured before the hemodynamic study. Results: HVPG could be measured in all patients, whereas LS could not be measured in 18 (18.5%) obese patients. In the 79 patients with valid LS, 32 (40.5%) had CSPH; mean HVPG was 8.8 +/- 4.7 mm Hg. Mean LS was 18.4 +/- 12.3 kPa. LS showed a moderate correlation with HVPG (r = 0.552; p <0.001). LS <13.6 kPa had high sensitivity (91%) but low specificity (57%) excluding CSPH. Conversely, LS >21 kPa had low sensitivity (53%) and high specificity (91%) predicting CSPH. 35% of patients had LS between 13.6 and 21 kPa (grey zone). Conclusions: These data suggest that in real-life scenarios half of patients with potentially resectable liver nodules can be non-invasively classified as having or not CSPH by LS. However, in the remaining half, LS is either not applicable or inaccurate. In this last population HVPG is still a non replaceable method to detect CSPH.
