Full textBackground and rationale: transient elastography is a noninvasive, validated, method allowing evaluation of liver fibrosis by measurement of liver stiffness and under investigation to predict the presence of esophageal varices. However, elastography has been validated only in diseases that progress to cirrhosis. In a literature review we found few studies on diagnostic accuracy in patients with non-cirrhotic portal hypertension. Aims: to evaluate the accuracy of hepatosplenic elastography (FibroScan and ARFI) to predict the presence of esophageal varices and whether varices are at risk of bleeding in patients with non-cirrhotic portal hypertension. To evaluate the concordances of the two techniques and correlate them with other indexes such as the platelet /spleen diameter ratio, APRI and FIB-4. Methods: patients with confirmed diagnosis of the following conditions were included: extrahepatic portal vein occlusion, schistosomiasis, idiopathic non-cirrhotic portal hypertension and congenital hepatic fibrosis. Upper digestive endoscopy was considered as a marker of the presence of clinically significant portal hypertension. Inclusion criteria: age above one year; defined etiological diagnosis; agreement of the patient or legal guardian to participate in the study. Exclusion criteria: cirrhosis confirmed by combination of clinical, imaging and laboratory diagnostic criteria or by liver biopsy when the result was available; post sinusoidal portal hypertension; conditions that technically preclude the performance of elastography (massive ascites and heart failure); splenectomy; pregnancy; advanced hepatocellular carcinoma. The study design was prospective, transversal, according to the STARD methodology, evaluating the accuracy, sensitivity, specificity, positive and negative predictive values and positive and negative likelihood ratios. The procedures of the study were: review of medical records data, abdominal ultrasonography and hepatosplenic elastography with FibroScan and ARFI equipment / methods. Cut-off points for elastography were determined by ROC curves. Results: liver stiffness measurement by FibroScan were 5.91 ± 1.87 kPa in extrahepatic portal vein occlusion, 8.89 ± 3.96 kPa in schistosomiasis, 10.60 ± 3.89 kPa in portal hypertension non-cirrhotic idiopathic and 10.30 ± 4.14 kPa in congenital hepatic fibrosis, whereas by ARFI were 1.27 ± 0.23 m/s; 1.35 ± 0.45 m/s; 1.43 ± 0.40 m/s; 1.55 ± 0.39 m/s; respectively. Spleen stiffness measurement by FibroScan were 60.82 ± 20.56 kPa in extrahepatic portal vein occlusion, 54.16 ± 22.94 kPa in schistosomiasis, 52.64 ± 21.97 kPa in idiopathic non-cirrhotic portal hypertension, and 48.50 ± 24.86 kPa in congenital hepatic fibrosis, while by ARFI were 3.22 ± 0.62 m/s; 3.01 ± 0.74 m/s; 2.86 ± 0.53 m/s; 2.80 ± 0.55 m/s; respectively. Liver stiffness measurement by FibroScan with a cut-off of 65.1 kPa had an accuracy of 0.62 (95%confidence interval, 0.46-0.78, p=0.121) for the presence of esophageal varices. The best cut-off point for predicting the presence of varices at high risk of bleeding was 40.05 kPa (accuracy, 0.63, 95% confidence interval, 0.52-0.76, p = 0.016). The spleen stiffness measurement by ARFI with a cut-off of 2.67 m/s showed (accuracy, 0.64, 95% confidence interval, 0.50-0.78, p=0.065) for the presence of esophageal varices. The best cut-off point for predicting the presence of varices at high risk of bleeding was 3.17 m/s (accuracy, 0.61, 95% confidence interval, 0.51-0.71, p=0.033) for varices at high risk of bleeding. Conclusions: spleen stiffness measurement by transient elastography (FibroScan and ARFI) presented a moderate accuracy and a high positive predictive value to diagnose the presence of esophageal varices. Spleen stifness by FibroScan when associated with platelet/spleen diameter ratio, there is a moderate accuracy with a high specificity to predict varices at high risk of bleeding. However, overlapping values between patients with or without varices was high and this precludes the clinical applicability of these methods

Full textBackground: The major determinant of the results of surgical resection for liver tumors is the volume and quality of the future liver remnant. The hepatopathy of the non-tumoral liver not only limits the type of surgery but also the risk of recurrence in primary liver tumors. With respect to liver metastasis, pre-operative chemotherapy is the usual treatment strategy and the hepatotoxicity of prolonged chemotherapy is an important risk factor for post-operative morbi-mortality. In patients with hepatocellular carcinoma (HCC) waiting for liver transplantation (LT), clinically significant portal hypertension (CSPH) is a risk for tumor progression and dropout of the waiting list for LT. Overall, degree of liver fibrosis and portal hypertension in the non-tumoral liver are important factors in the management of patients with liver tumors as they determine the prognosis of patients after hepatectomy. FibroScan®, which estimate the degree of liver fibrosis and steatosis, could utilized to evaluate the non-tumoral liver and predict the post-operative outcomes and the risk of dropout from the list of LT in HCC patients waiting for LT. Methods: Consecutive patients programmed to undergo hepatectomy or LT were included in the present study prospectively after an informed consent. Liver stiffness (LS) and controlled attenuation parameter (CAP) were measured pre-operatively by transient elastography using FibroScan® 502 Touch Standard device with M or XL probes. Results: LS-based nomograms that were developed and valided in this study were accurate to predict 90-day severe morbidity and 90-day mortality after hepatectomy for various hepatobiliary diseases. In patients with HCC undergoing hepatectomy, elevated LS ≥22 kPa was a risk factor for persistent hepatic decompensation beyond the 90-day post-operative period. Moreover, LS ≥30 kPa and CAP <240 dB/m were associated with poor oncological outcomes after resection and thus could be a surrogate biomarker of more aggressive HCC. The discriminatory ability of LS to diagnose advanced liver fibrosis (AUROC: 0.95) and cirrhosis (AUROC: 0.97) was validated in the present study. Further, CAP had a satisfactory performance to screen significant hepatic steatosis (S≥2) with AUROC of 0.70. A new LS-based model called HVPG10 score was developed and validated to diagnose CSPH. With a cut-off of 15, it was capable of accurately ruling out CSPH in >95% of the patients with chronic liver disease and would avoid further unnecessary investigations. Conclusion: Pre-operative evaluation of patients with transient elastography would enable surgeons to predict major complications and mortality after hepatectomy with LS-based nomograms. In patients with HCC, LS ≥30 kPa was an important risk factor of incomplete surgical resection, early recurrence after hepatectomy and for tumor progression and dropout while waiting for LT. Therefore, LT must be the primary treatment in HCC patients with LS ≥30 kPa
