Abstract
ABSTRACT Patients with compensated advanced chronic liver disease (cACLD) can safely spared screening esophagogastroduodenoscopy (EGD) when they meet the Baveno VI criteria as assessed by transient elastography. Recently, the cutoff values of the Baveno VI criteria assessed by 2-dimensional shear wave elastography (2D-SWE) were proposed. We aimed to validate it to rule out high-risk varices (HRVs) in cACLD patients; combine spleen diameter (SPD) with the Baveno VI criteria and assess whether it can spare more screening EGD. A total of 173 cACLD patients with successful liver stiffness (LS) measurements and EGD examinations were included. We analyzed the risk factors that predicted HRVs and compared the performances of different models for ruling out HRVs. The platelet count, LS, and SPD were independent predictors of HRVs. The AUCs of platelet count, LS, spleen stiffness and SPD for diagnosing HRVs were 0.797, 0.757, 0.834, and 0.804, respectively. The Baveno VI criteria assessed by 2D-SWE spared 25.4% of EGD screenings and missed 2.4% of the HRV patients. Combining SPD ≤11.1 cm with the Baveno VI criteria could spare more EGD screenings than just applying the Baveno VI criteria (45.1% vs 25.4%, P < 0.001), and missed 4.9% of the HRV patients. The Baveno VI criteria assessed by 2D-SWE could be safely applied in cACLD patients to rule out HRV patients. The combined model Baveno VI/SPD could safely and significantly increase the rate of spared EGD.

A systematic review and meta-analysis. Eur J Radiol 2024; 175:111475. [PMID: 38643527 DOI: 10.1016/j.ejrad.2024.111475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 03/12/2024] [Accepted: 04/17/2024] [Indexed: 04/23/2024]
Abstract
OBJECTIVES To systematically review the accuracy of spleen stiffness measurement (SSM) by 2D- Shear Wave Elastography (2D-SWE) in predicting high risk for bleeding varices (HRV) in cirrhotic patients. METHODS PubMed, Embase, Web of Science, Medline, Cochrane, and Google Scholar databases were searched up to 31/05/2023 for all human studies using 2D-SWE to estimate SSM and endoscopy to detect HRV. Meta-analysis was performed using a generalized linear mixed model. Publication bias was evaluated using the funnel plot asymmetry test. The Area Under the Summarized Receiver Operating Characteristic curve (AUSROC) was estimated using the "mada" package. RESULTS A total of 13 studies and 1970 patients were included. Of them, 27.8 % had HRV. The pooled sensitivity and polled specificity of SSM in detecting HRV were 90 % (95 %CI:87-92 %) and 68 % (95 %CI:58-77 %), respectively, with an AUSROC at 0.86 (95 %CI:0.82-0.90). The median cutoff value of SSM in detecting HRV was 34.2 kPa. In studies including exclusively HBV cirrhotic patients, SSM's polled sensitivity and specificity in predicting HRV was 88 % (95 %CI:82-92 %) and 73 % (95 %CI:68-78 %), respectively. The AUSROC was 0.84 (95 %CI:0.81-0.87). The number of repeated measurements per patient (<5 or ≥ 5) did not affect the method's capability. Using Aixplorer to evaluate SSM had a higher sensitivity in ruling out HRV than other 2D-SWE devices. CONCLUSIONS Our meta-analysis supports that SSM by 2D-SWE has a good diagnostic performance for ruling out HRV in cirrhosis.

A Combined Baveno VII and Spleen Stiffness Algorithm to Improve the Noninvasive Diagnosis of Clinically Significant Portal Hypertension in Patients With Compensated Advanced Chronic Liver Disease. Am J Gastroenterol 2022; 117:1825-1833. [PMID: 35973171 DOI: 10.14309/ajg.0000000000001887] [Citation(s) in RCA: 29] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 06/08/2022] [Indexed: 12/11/2022]
Abstract
INTRODUCTION A noninvasive diagnosis of clinically significant portal hypertension (CSPH) has important prognostic and therapeutic implications for patients with compensated advanced chronic liver disease. We aimed to validate and improve the available algorithms for the CSPH diagnosis by evaluating spleen stiffness measurement (SSM) in patients with compensated advanced chronic liver disease. METHODS This is a retrospective study including patients with liver stiffness measurement (LSM) ≥10 kPa, no previous decompensation, and available measurements of hepatic venous pressure gradient, LSM, and SSM by transient elastography referring to our center in Bologna. The diagnostic algorithms were adequate if negative and positive predictive values were >90% when ruling out and ruling in CSPH, respectively; these models were validated in a cohort from Verona. The 5-year decompensation rate was reported. RESULTS One hundred fourteen patients were included in the derivation cohort. The Baveno VII diagnostic algorithm (LSM ≤15 kPa + platelet count ≥150 × 10 9 /L to rule out CSPH and LSM >25 kPa to rule in CSPH) was validated; however, 40%-60% of the patients remained in the gray zone. The addition of SSM (40 kPa) to the model significantly reduced the gray zone to 7%-15%, maintaining adequate negative and positive predictive values. The diagnostic algorithms were validated in a cohort of 81 patients from Verona. All first decompensation events occurred in the "rule-in" zone of the model including SSM. DISCUSSION The addition of SSM significantly improves the clinical applicability of the algorithm based on LSM and platelet count for CSPH diagnosis. Our models can be used to noninvasively identify candidates for nonselective beta-blocker treatment and patients at a high risk of decompensation.

Abstract
OBJECTIVES To investigate the usefulness of the criteria with liver stiffness (LS) measured by two-dimensional shear wave elastography (2D-SWE) and platelet count (PLT) for ruling out high-risk varices in patients with compensated advanced chronic liver disease (cACLD). METHODS A total of 661 patients with cACLD had successfully undergone 2D-SWE and endoscopy screening. We analyzed risk factors for the presence of high-risk varices and compared proportions of patients who were spared endoscopy when used the predicting criteria with LS (ranged from 16 to 25 kPa) and PLT (ranged from 80 × 109/L to 150 × 109/L). RESULTS PLT, albumin, LS were found to be independent predictors of high-risk varices. The LS values for ruling out and ruling in high-risk varices were 14.0 kPa and 24.8 kPa, respectively. When the Baveno VI criteria LS < 20 kPa and PLT > 150 × 109/L were used, the high-risk varices miss rate was 2.1%, while the saved endoscopy rate only was 19.2%. The new criteria that LS < 16 kPa and PLT > 100 × 109/L saved 30.4-34.6% endoscopy with 0-3.2% high-risk varices miss rate in the subgroup analysis stratified according to the types of underlying liver disease. CONCLUSIONS The Baveno VI criteria can be applied to LS measurement by 2D-SWE. The new criteria that LS < 16 kPa and PLT > 100 × 109/L could be a potential model to spare more endoscopy screening with < 5% high-risk varices miss rate. KEY POINTS • LS measured by 2D-SWE is reliable predictive factor for predicting all-size varices and high-risk varices in patients with compensated advanced chronic liver disease. • LS measured by 2D-SWE < 16 kPa and PLT > 100 × 109 /L, which can spare more endoscopy than Baveno VI criteria with < 5% high-risk varices miss rate. • The Baveno VI criteria can be applied to LS measurement by 2D-SWE.

Abstract
Portal hypertension is the main driver of complications in patients with advanced chronic liver disease (ACLD) and is defined by values of hepatic venous pressure gradient measurement (HVPG) >5 mmHg. Values of HVPG ≥10 mmHg determine the presence of clinically significant portal hypertension (CSPH), the main predictor of the risk of variceal bleeding, hepatic decompensation, and mortality. However, its measurement is invasive and requires high expertise, so its routine use outside third level centers or clinical trials is limited. In the last decades, several non-invasive tests (NITs) have been developed and validated for the diagnosis of portal hypertension. Among these, liver (LSM) and spleen stiffness measurement (SSM) are the most promising tools available, as they have been proven accurate to predict CSPH, high-risk esophageal varices, decompensation, and mortality in patients with ACLD. In the last Baveno VI Consensus proceedings, LSM evaluation was recommended for the first time for diagnosis of CSPH (LSM >20-25 kPa) and the screening of patients with a low probability of having high-risk varices (LSM <20 kPa and platelet count >150.000/mm3). In this review, we aimed to summarize the growing evidence supporting the use of non-invasive tests for the evaluation of portal hypertension in patients with chronic liver disease.

Spleen Stiffness for Predicting Varices Needing Treatment: Comparison between Two Different Elastography Techniques (Point vs. 2D-SWE). Can J Gastroenterol Hepatol 2021; 2021:6622726. [PMID: 34055675 PMCID: PMC8130909 DOI: 10.1155/2021/6622726] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 03/17/2021] [Accepted: 03/19/2021] [Indexed: 02/06/2023] Open
Abstract
The study aimed to establish the benefits of using spleen stiffness values measured by two elastography techniques as noninvasive markers for predicting varices needing treatment and comparing their performances. A prospective study was performed, including 107 subjects with compensated liver cirrhosis, who underwent upper digestive endoscopy, as well as spleen stiffness measurements by means of two elastography techniques: pSWE (point shear wave elastography using Virtual Touch Quantification-Siemens Acuson S2000) and 2D-SWE (2D-shear wave elastography-LOGIQ E9, General Electric). Reliable spleen stiffness measurements were obtained in 96.2% (103/107) patients by means of 2D-SWE and in 94.4% (101/107) subjects with pSWE; therefore, 98 subjects were included in the final analysis, of which 40.8% (40/98) had varices needing treatment. The optimal spleen stiffness cut-off value by 2D-SWE for predicting varices needing treatment was 13.2 kPa (AUROC 0.84), while for pSWE, it was 2.91 m/s (AUROC 0.90). Based on AUROC comparison, no difference between the performance of the two techniques for predicting varices needing treatment was found (p=0.1606). In conclusion, spleen stiffness measured by either 2D-SWE or pSWE is a reliable surrogate marker, with good feasibility, applicability, and predictive accuracy for varices needing treatment, with no significant difference between techniques.
