To compare the magnetic resonance imaging (MRI) features of benign liver lesions developed on Budd-Chiari syndrome (BCS) with those on Fontan-associated liver disease (FALD) and to describe their long-term progression.Patients with BCS or FALD who underwent MRI between 2010 and 2020 were retrospectively included. MRI features of nodules (≥ 5 mm) at baseline and at final follow-up were reviewed. The final diagnosis of benign lesion was based on a combination of clinical and biological data and findings at follow-up MRI examination.Two-hundred and thirty benign liver lesions in 39 patients with BCS (10 men, 29 women; mean age, 36 ± 11 [SD] years; age range: 15-66 years) and 84 benign lesions in 14 patients with FALD (2 men, 12 women; mean age, 31 ± 10 [SD] years; age range: 20-48 years) were evaluated. On baseline MRI, BCS nodules were more frequently hyperintense on T1-weighted (183/230, 80%) and hypointense on T2-weighted (142/230; 62%) images, while FALD nodules were usually isointense on both T1- (70/84; 83%) and T2-weighted (64/84; 76%) images (all P0.01). Most lesions showed arterial phase hyperenhancement (222/230 [97%] vs. 80/84 [95%] in BCS and FALD, respectively; P = 0.28) but wash-out was more common in BCS (64/230 [28%] vs. 9/84 [11%]; P0.01). At follow-up, changes were more frequent in BCS nodules with more frequent disappearance (P0.01), changes in size, signal intensity on T2-weighted, portal, and delayed phase, and in the depiction of washout and capsule (all P ≤ 0.03).MRI features of benign lesions are different at diagnosis and during the course of the disease between BCS and FALD. Changes in size and MRI features are more frequent in benign lesions developed in BCS.

Background & Aims: Vascular liver diseases (VLDs) are represented mainly by portosinusoidal vascular disease (PSVD), noncirrhotic splanchnic vein thrombosis (SVT), and Budd Chiari syndrome (BCS). It is unknown whether patients with VLDs constitute a high-risk population for complications and greater coronavirus disease 2019 (COVID-19)-related mortality from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Our objective was to assess the prevalence and severity of SARS-CoV-2 infection among patients with VLDs, as well as to assess its impact on hepatic decompensation and survival. Methods: This is an observational international study analyzing the prevalence and severity of SARS-CoV-2 infection in VLDs between March 2020 and March 2021, compared with the general population (GP). Patients from Spain (5 centers; n = 493) and France (1 center; n = 475) were included. Results: Nine hundred sixty-eight patients were included: 274 with PSVD, 539 with SVT, and 155 with BCS. Among them, 138 (14%) were infected with SARS-CoV-2: 53 with PSVD, 77 with SVT, and 8 with BCS. The prevalence of SARS-CoV-2 infection in patients with PSVD (19%) and SVT (14%) was significantly higher than in the GP (6.5%; P < .05), whereas it was very similar in patients with BCS (5%). In terms of infection severity, patients with VLDs also presented a higher need of hospital admission (14% vs 7.3%; P < .01), intensive care unit admission (2% vs 0.7%; P < .01), and mortality (4% vs 1.5%; P < .05) than the GP. Previous history of ascites (50% vs 8%; P < .05) and post-COVID-19 hepatic decompensation (50% vs 4%; P < .05) were associated with COVID-19 mortality. Conclusions: Patients with PSVD and SVT could be at higher risk of infection by SARS-CoV-2 and at higher risk of severe COVID-19 disease. © 2021 AGA Institute

Background: The Baveno VI consensus proposed a dual liver stiffness (LS) by transient elastography threshold of 15 kPa for excluding and diagnosing compensated advanced chronic liver disease (cACLD) in the absence of other clinical signs. Herein, we aimed to validate these criteria in a real-world multicentre study. Methods: We included 5,648 patients (mean age 51 ± 13 years, 53% males) from 10 European liver centres who had a liver biopsy and LS measurement within 6 months. We included patients with chronic hepatitis C (n = 2,913, 52%), non-alcoholic fatty liver disease (NAFLD, n = 1,073, 19%), alcohol-related liver disease (ALD, n = 946, 17%) or chronic hepatitis B (n = 716, 13%). cACLD was defined as fibrosis stage ≥F3. Results: Overall, 3,606 (66%) and 987 (18%) patients had LS 15 kPa, respectively, while cACLD was histologically confirmed in 1,772 (31%) patients. The cut-offs of 15 kPa showed 75% sensitivity and 96% specificity to exclude and diagnose cACLD, respectively. Examining the ROC curve, a more optimal dual cut-off at 12 kPa, with 91% sensitivity and 92% specificity for excluding and diagnosing cACLD (AUC 0.87; 95% CI 0.86–0.88; p 15 kPa dual cut-offs, we found that the 12 kPa dual cut-offs have better diagnostic accuracy in cACLD. Lay summary: The term compensated advanced chronic liver disease (cACLD) was introduced in 2015 to describe the spectrum of advanced fibrosis and cirrhosis in asymptomatic patients. It was also suggested that cACLD could be diagnosed or ruled out based on specific liver stiffness values, which can be non-invasively measured by transient elastography. Herein, we assessed the suggested cut-off values and identified alternative values that offered better overall accuracy for diagnosing or ruling out cACLD.

Objectives We have confirmed the diagnostic value of protein induced by vitamin K absence or antagonist-II (PIVKA-II) in a French cohort of patients with hepatocellular carcinoma (HCC). Herein, we aim to study the biological response under treatment and the prognostic value of PIVKA-II serum level in patients treated for HCC. Methods Patients with primary HCC developed chronic liver disease with serum PIVKA-II, and alpha-fetoprotein (AFP) levels available at baseline and after first HCC treatment [within 3 months (M1-M3) and/or within 6-9 months (M6-M9)] were included. Results A total of 94 patients were included. Median follow-up was 23 months (range 11-31 months). PIVKA-II levels significantly decreased from baseline to M1-M3 (P = 0.002) and to M6-M9 (P = 0.035). By multivariate analysis, biological response (M1-M3/baseline PIVKA-II ratio) independently and significantly predicted overall survival (OS). A ratio below 0.73 was able to identify patients with the better prognosis in the total population [OS: 27 months (range 17-31) vs. 17 (range 9-25); P = 0.008] and in patients who had transarterial chemoembolization or selective internal radiation therapy as first treatment approach [OS: 26 months (range 14-31) vs. 16 (range 9-25); P = 0.002 and 2-year OS of 73% vs. 30%; P = 0.009]. PIVKA-II serum levels at baseline and PIVKA-II biological response were significantly associated with radiological response. Conclusion PIVKA-II serum level seems to be a good prognostic and promising biomarker for early monitoring treatment outcomes for patients with HCC.

Microvesicles (MVs) are extracellular vesicles released by cells following activation or apoptosis. Some MV subpopulations augment with cirrhosis severity and contribute to portal hypertension. This study aimed at determining if plasma MV levels can estimate the presence of hepatic venous pressure gradient (HVPG) ≥10 mm Hg and predict mortality in patients with advanced chronic liver disease. All patients with severe fibrosis or cirrhosis undergoing liver catheterization between 2013 and 2015 at two centers were prospectively included. We measured circulating levels of annexin V+ , platelet, leukocyte, endothelial, and hepatocyte MVs. The test cohort included 139 patients. Hepatocyte MV levels were 4.0-fold and 2.2-fold higher in patients with Child-Pugh C than in those with Child-Pugh A or B liver disease, respectively. Levels of other MV subpopulations were not influenced by liver disease severity. Hepatocyte MV levels correlated with HVPG but could not identify patients with HVPG ≥10 mm Hg. Hepatocyte MV level >65 U/L predicted 6-month mortality independently of Child-Pugh score and of Model for End-Stage Liver Disease (MELD). Patients with hepatocyte MV levels >65 U/L and MELD >15 had a higher 6-month mortality than other patients (23% versus 3%; P = 0.001). These findings were confirmed in a validation cohort including 103 patients. Conclusion Circulating MV levels cannot identify patients with HVPG ≥10 mm Hg; by contrast, hepatocyte MV levels strongly improve prediction of 6-month mortality in patients with advanced chronic liver disease; therapies associated with decreased levels of circulating hepatocyte MV might be attractive strategies in patients with severe cirrhosis. (Hepatology 2018).

Two algorithms based on sequential measurements of liver and spleen stiffness using two-dimensional shearwave elastography (2D-SWE) have been recently proposed to estimate clinically significant portal hypertension (hepatic venous pressure gradient [HVPG] ≥10 mm Hg) in patients with cirrhosis, with excellent diagnostic accuracy.To validate externally these algorithms in a large cohort of patients with cirrhosis.One hundred and ninety-one patients with stable cirrhosis (Child-Pugh class A 39%, B 29% and C 31%) who underwent liver and spleen stiffness measurements using 2D-SWE at the time of HVPG measurement were included. Diagnostic accuracy of the 2 algorithms was assessed by calculating sensitivity, specificity, positive and negative predictive values.The first algorithm, using liver stiffness16.0 kilopascals (kPa) and then spleen stiffness26.6 kPa, was used to rule-out HVPG ≥10 mm Hg. In our population, its sensitivity and negative predictive value were 95% and 63% respectively. The second algorithm, using liver stiffness38.0 kPa, or liver stiffness ≤38.0 kPa but spleen stiffness27.9 kPa, was used to rule-in HVPG ≥10 mm Hg. In our population, its specificity and positive predictive value were 52% and 83% respectively. Restricting the analyses to the 74 patients without any history of decompensation of cirrhosis or to the 65 patients with highly reliable liver stiffness measurement did not improve the results.In our population, diagnostic accuracies of non-invasive algorithms based on sequential measurements of liver and spleen stiffness using 2D-SWE were acceptable, but not good enough to replace HVPG measurement or to base clinical decisions.

Data on the consequences of cirrhosis regression on portal hypertension and on splanchnic and systemic hemodynamic are scarce. Previous studies have reported a decrease in hepatic venous pressure gradient following antiviral treatment in patients with hepatitis B or C related cirrhosis. However, these studies did not investigate splanchnic and systemic hemodynamic changes associated with virus control. To fill this gap in knowledge, in a recent issue of Clinical Science, Hsu et al. (vol. 132, issue 6, 669-683) used rat models of cirrhosis induced by thioacetamide and by bile duct ligation and provided a comprehensive analysis of the effects of cirrhosis regression on splanchnic and systemic hemodynamics. They observed a significant reduction in portal pressure accompanied by a normalization of systemic hemodynamic (normal cardiac index and systemic vascular resistance) and a decrease in intrahepatic vascular resistance. No change in extrahepatic vascular structures were observed despite normalization of collateral shunting, meaning that portosystemic collaterals persist but are not perfused. One intriguing part of their results is the only marginal effect of cirrhosis regression on liver hyperarterialisation. This result suggests that changes in splanchnic hemodynamic features induced by cirrhosis remain when hepatic vascular resistance decreases, raising the hypothesis of an autonomous mechanism persisting despite regression of intrahepatic vascular resistance. Microbiota changes and bacterial translocation might account for this effect. In conclusion cirrhosis regression normalizes systemic hemodynamics, but some splanchnic hemodynamic changes persist including extrahepatic angiogenesis and liver hyperarterialization.

Management of Budd–Chiari syndrome (BCS) is complex, mostly due to the variability of clinical presentation, cumulating bleeding, and thrombotic risk; symptoms vary from asymptomatic to severe portal hypertension and liver failure, in the context of concurring multifactorial prothombotic diseases. These modifications result in precarious hemostatic equilibrium with an increased risk of bleeding and thrombosis in a situation where a multidisciplinary approach combining medical and interventional therapy is considered. For more than 15 years, a stepwise treatment strategy according to response to previous therapy (from less to more invasiveness) has been proposed and is largely used worldwide. The first step consists of pharmacological management with anticoagulation therapy, specific therapy of underlying thrombotic disease, and medical or endoscopic management of liver-related complications. Recanalization of accessible stenosis is systematically considered and performed with angioplasty or stenting when it is feasible. In patients who do not respond to this first step therapy, transjugular intrahepatic portosystemic shunt is proposed, and as a fourth step, orthotopic liver transplantation. This chapter reviews the current rationale, indications, and modalities of anticoagulation therapy in BCS patients considering the balance of efficacy and safety, in this unstable situation of high bleeding vs high recurrent thrombosis risk.

It remains unclear whether the classic imaging criteria for the non-invasive diagnosis of hepatocellular carcinoma (HCC) can be applied to chronic vascular liver diseases, such as Budd-Chiari syndrome (BCS). Herein, we aimed to evaluate the diagnostic value of washout for the discrimination between benign and malignant lesions in patients with BCS.This retrospective study included all patients admitted to our institution with a diagnosis of BCS and focal lesions on MRI from 2000 to 2016. MRI images were reviewed by 2 radiologists blinded to the nature of the lesions. Patient and lesion characteristics were recorded, with a focus on washout on portal venous and/or delayed phases. Lesions were compared using Chi-square, Fisher's, Student's t or Mann-Whitney U tests.A total of 49 patients (mean age 35 ± 12 years; 34 women [69%] and 15 men [31%]) with 241 benign lesions and 12 HCC lesions were analyzed. Patients with HCC were significantly older (mean age 44 ± 16 vs. 33 ± 9 years, p = 0.005), with higher alpha-fetoprotein (AFP) levels (median 16 vs. 3 ng/ml, p = 0.007). Washout was depicted in 9/12 (75%) HCC, and 69/241 (29%) benign lesions (p0.001). A total of 52/143 (36%) lesions ≥1 cm with arterial hyperenhancement showed washout (9 HCC and 43 benign lesions). In this subgroup, the specificity of washout for the diagnosis of HCC was 67%. Adding T1-w hypointensity raised the specificity to 100%. A serum AFP15 ng/ml was associated with 95% specificity.Washout was observed in close to one-third of benign lesions, leading to an unacceptably low specificity for the diagnosis of HCC. The non-invasive diagnostic criteria proposed for cirrhotic patients cannot be extrapolated to patients with BCS.Washout on MRI is depicted in a significant proportion of benign nodules in patients with Budd-Chiari syndrome (BCS), limiting its value for the differentiation between benign and malignant lesions. Criteria proposed for the non-invasive diagnosis of hepatocellular carcinoma in patients with cirrhosis cannot be extrapolated to patients with BCS. Additional imaging findings and patient characteristics, including alpha-fetoprotein serum level, can help determine the probability of a nodule being HCC in patients with BCS.

Primary Budd-Chiari syndrome (BCS) is defined as hepatic venous outflow obstruction from small hepatic veins to the inferior vena cava (IVC), due to thrombosis or fibrous stenosis of these veins. In Western countries, one or multiple prothombotic diseases are usually identified, mainly myeloproliferative neoplasms. New noninvasive diagnostic tools facilitate the diagnosis of these causes which may be difficult to detect in the presence of portal hypertension (PH) or liver failure.

There is debate over the effects of long-term oral fluoroquinolone therapy in patients with advanced cirrhosis. We performed a randomized controlled trial to evaluate the effects of long-term treatment with the fluoroquinolone norfloxacin on survival of patients with cirrhosis.We performed a double-blind trial of 291 patients with Child-Pugh class C cirrhosis who had not received recent fluoroquinolone therapy. The study was performed at 18 clinical sites in France from April 2010 through November 2014. Patients were randomly assigned to groups given 400 mg norfloxacin (n = 144) or placebo (n = 147) once daily for 6 months. Patients were evaluated monthly for the first 6 months and at 9 months and 12 months thereafter. The primary outcome was 6-month mortality, estimated by the Kaplan-Meier method, censoring spontaneous bacterial peritonitis, liver transplantation, or loss during follow-up.The Kaplan-Meier estimate for 6-month mortality was 14.8% for patients receiving norfloxacin and 19.7% for patients receiving placebo (P = .21). In competing risk analysis that took liver transplantation into account, the cumulative incidence of death at 6 months was significantly lower in the norfloxacin group than in the placebo group (subdistribution hazard ratio, 0.59; 95% confidence interval, 0.35-0.99). The subdistribution hazard ratio for death at 6 months with norfloxacin vs placebo was 0.35 (95% confidence interval, 0.13-0.93) in patients with ascites fluid protein concentrations15 g/L and 1.39 (95% confidence interval, 0.42-4.57) in patients with ascites fluid protein concentrations ≥15 g/L. Norfloxacin significantly decreased the incidence of any and Gram-negative bacterial infections without increasing infections caused by Clostridium difficile or multiresistant bacteria.In a randomized controlled trial of patients with advanced cirrhosis without recent fluoroquinolone therapy, norfloxacin did not reduce 6-month mortality, estimated by the Kaplan-Meier method. Norfloxacin, however, appears to increase survival of patients with low ascites fluid protein concentrations. ClinicalTrials.gov ID: NCT01037959.

The diagnosis of alcoholic hepatitis (AH) often requires a transjugular liver biopsy (TJLB), a procedure that is not always readily accessible. We analyzed plasma biomarkers to estimate the presence of histological features of AH among patients with clinical suspicion of AH. Using enzyme-linked immunosorbent assay, we tested M65 and M30 (circulating fragments of cytokeratin-18) and their respective fraction carried by microvesicles (MVs), CCL20 and TREM1. Leukocyte, platelet, and endothelial-derived MVs were quantified by way of flow cytometry. Test and validation cohorts prospectively included patients with clinical features of AH undergoing TJLB. In the test cohort, 46 of 83 (55%) patients showed histological features of AH. Age, bilirubin, INR, and creatinine (ABIC) score was B or C in 83%. Patients with histologically proven AH had higher levels of total and MV-bound M65 and total and MV-bound M30 and CCL20 than those without (P < 0.001 for all tests). Levels of TREM-1 and of subpopulations of MVs were not different between groups. M65 and M30 both had an area under the receiver operating characteristics curve of 0.84 to estimate the presence of AH. For M65, a cutoff of 2000 IU/L had a positive predictive value of 91%, whereas a cutoff of 641 IU/L had a negative predictive value of 88%. In the validation cohort, AH was histologically confirmed in 48 of 68 (71%) patients. ABIC score was B or C in 69% of patients. For M65, the above cutoffs had a diagnostic accuracy of 81%. Even better results were obtained in patients with suspicion of severe AH (ABIC B or C) in both cohorts. Conclusion: Plasma levels of cytokeratin-18 fragments are reliable noninvasive markers of AH. Using the proposed cutoffs for M65, two thirds of TJLB can be avoided, which can be useful in centers where this technique is not readily available. (Hepatology 2017;66:555–563).

Summary Background Beta-blockers may have to be interrupted in patients with cirrhosis. The concept of a rebound after interruption of beta-blockers is based on an animal study and on isolated case reports of variceal bleeding. Aim To determine if a rebound occurs in patients with cirrhosis following abrupt interruption of beta-blockers. Methods We prospectively included all consecutive patients with cirrhosis undergoing right heart and hepatic vein catheterisation. Four groups were defined: ‘no beta-blockers’ including patients not receiving beta-blockers; ‘≤1 day’, ‘2–3 days’ and ‘≥4 days’ classified according to the time patients had interrupted beta-blockers before catheterisation. Results were expressed as median (interquartile range). Results A total of 150 patients were included. Among the 25 patients in the groups ‘2–3 days’ and ‘≥4 days’, median duration of beta-blockers interruption was 4 (3–6) days. No gastrointestinal bleeding occurred during that period, nor during the following month. Hepatic venous pressure gradient was not different among patients in usually treated with beta-blockers. After adjustment, beta-blockers interruption was not associated with hepatic venous pressure gradient. Cardiac index was higher in the ‘≥4 days’ group [4.6 L/min/m2 (3.5–5.1)] than in the ‘≤1 day’ group [3.4 (2.6–4.0); P = 0.001] or in the ‘2–3 days’ group [3.1 (2.7–3.7); P = 0.007], but not different from the ‘no beta-blockers’ group. Conclusions Abrupt interruption of beta-blockers is associated neither with an apparent increase in the risk of variceal bleeding nor with a haemodynamic rebound. Thus, interruption of beta-blockers in patients with cirrhosis may not require particular dosing or surveillance.

International audience; Aim: The efficacy of a cetuximab-based regimen used to treat metastatic colorectal cancer (mCRC) could be influenced by VEGFA polymorphisms. Materials & methods: We studied the effects of five polymorphisms in the VEGFA gene (-2549D/I, -1154G/A, -460T/C, +405G/C and +936C/T) on the outcome of 98 mCRC patients treated with FOLFIRI plus cetuximab. Results: Patients homozygous for the -2549D, -1154G and -460T alleles did exhibit higher response rates to treatment and longer progression-free survival compared with others. In addition, the DGTGC and IGCGC haplotypes were significantly associated with a lower risk of disease progression. Conclusion: These findings suggest that VEGFA genetic variations might influence response/resistance of FOLFIRI plus cetuximab treatment in mCRC patients.

Many years after therapeutic wilderness, sorafenib finally showed a clinical benefit in patients with advanced hepatocellular carcinoma. After the primary general enthusiasm worldwide, some disappointments emerged particularly since no new treatment could exceed or at least match sorafenib in this setting. Without these new drugs, research focused on optimizing care of patients treated with sorafenib. One challenging research approach deals with identifying prognostic and predictive biomarkers of sorafenib in this population. The task still seems difficult; however appropriate investigations could resolve this dilemma, as observed for some malignancies where other drugs were used.

Summary Background and aims Severe acute hepatotoxicity is a well known complication following the ingestion of ecstasy (3,4-methylenedioxymethamphetamine [MDMA] ecstasy). Hepatic dysfunction has also been reported after acute cocaine intoxication. However, chronic hepatitis after prolonged use of ecstasy and/or cocaine has rarely been reported. Methods We report the case of a 27-year-old woman hospitalized with edema, ascites and severe liver failure (prothrombin rate 33%), following the use of ecstasy and cocaine over the previous 9 months. Clinical, biological, radiological and pathology findings were recorded at admission and over 8 years’ follow-up. Results Liver biopsy showed architectural distortion caused by bridging fibrosis, proliferation of cholangioles, and lesions of active interface hepatitis. Other causes of acute and chronic liver disease were excluded. Magnetic resonance imaging showed marked liver fibrosis. After withdrawal of both substances clinical examination and liver function tests progressively normalized. Long-term monitoring with magnetic resonance imaging showed progressive regression of fibrosis. Conclusion Use of ecstasy and cocaine may cause chronic hepatitis leading to marked liver fibrosis, which may regress after withdrawal of both substances.

Background & Aims A total of 15% of patients with idiopathic non-cirrhotic portal hypertension (INCPH) are women of childbearing age. We aimed to determine maternal and fetal outcome of pregnancies occurring in women with INCPH. Methods We retrospectively analyzed the charts of women with INCPH followed in the centers of the VALDIG network, having had ≥1 pregnancy during the follow-up of their liver disease. Data are represented as median (interquartile range). Results A total of 24 pregnancies occurred in 16 women within 24 (5–66) months after INCPH diagnosis. Four women had associated partial portal vein thrombosis before pregnancy. At conception, 2 out of the 16 women had detectable ascites and others were asymptomatic. Out of these 24 pregnancies, there were four miscarriages, one ectopic pregnancy, and one medical termination of pregnancy at 20 weeks of gestation. Out of the 18 other pregnancies reaching 20 weeks of gestation (in 14 patients), there were nine preterm and nine term deliveries. All infants were healthy at delivery, but one died at day 1 of unknown cause and one at day 22 of infectious meningitis; both were preterm. Concerning mothers, two had worsening of ascites, two had variceal bleeding despite non-selective betablockers during pregnancy and one developed a main portal vein thrombosis in early postpartum. Genital bleeding occurred in three patients, including two receiving anticoagulation. All 16 women were alive and asymptomatic after a median follow-up of 27 (9–93) months after last delivery. Conclusion The overall outcome of women with INCPH who become pregnant is favorable despite a significant incidence of complications related to portal hypertension. Fetal outcome is favorable in most pregnancies reaching 20 weeks of gestation. Lay summary About 15% of patients with idiopathic non-cirrhotic portal hypertension are women of childbearing age, who can become pregnant. As available reports on pregnancy in these women are scarce and heterogeneous, it is unclear whether or not pregnancy should be contraindicated in this setting. We provide detailed data showing that, regardless of the associated conditions, the overall outcome of women with idiopathic non-cirrhotic portal hypertension becoming pregnant is good despite a significant incidence of complications related to portal hypertension, and that fetal outcome is favorable in most pregnancies reaching 20 weeks of gestation.

In patients with idiopathic noncirrhotic portal hypertension (INCPH), data on morbidity and mortality of abdominal surgery are scarce. We retrospectively analyzed the charts of patients with INCPH undergoing abdominal surgery within the Vascular Liver Disease Interest Group network. Forty‐four patients with biopsy‐proven INCPH were included. Twenty‐five (57%) patients had one or more extrahepatic conditions related to INCPH, and 16 (36%) had a history of ascites. Forty‐five procedures were performed, including 30 that were minor and 15 major. Nine (20%) patients had one or more Dindo‐Clavien grade ≥ 3 complication within 1 month after surgery. Sixteen (33%) patients had one or more portal hypertension–related complication within 3 months after surgery. Extrahepatic conditions related to INCPH (P = 0.03) and history of ascites (P = 0.02) were associated with portal hypertension–related complications within 3 months after surgery. Splenectomy was associated with development of portal vein thrombosis after surgery (P = 0.01). Four (9%) patients died within 6 months after surgery. Six‐month cumulative risk of death was higher in patients with serum creatinine ≥ 100 μmol/L at surgery (33% versus 0%, P < 0.001). An unfavorable outcome (i.e., either liver or surgical complication or death) occurred in 22 (50%) patients and was associated with the presence of extrahepatic conditions related to INCPH, history of ascites, and serum creatinine ≥ 100 μmol/L: 5% of the patients with none of these features had an unfavorable outcome versus 32% and 64% when one or two or more features were present, respectively. Portal decompression procedures prior to surgery (n = 10) were not associated with postoperative outcome. Conclusion: Patients with INCPH are at high risk of major surgical and portal hypertension–related complications when they harbor extrahepatic conditions related to INCPH, history of ascites, or increased serum creatinine.

Early diagnosis of acute mesenteric ischemia (AMI) remains a clinical challenge, and no biomarker has been consistently validated. We aimed to assess the accuracy of three promising circulating biomarkers for diagnosing AMI—citrulline, intestinal fatty acid-binding protein (I-FABP), and d-lactate. A cross-sectional diagnostic study enrolled AMI patients admitted to the intestinal stroke center and controls with acute abdominal pain of another origin. We included 129 patients—50 AMI and 79 controls. Plasma citrulline concentrations were significantly lower in AMI patients compared to the controls [15.3 μmol/L (12.0–26.0) vs. 23.3 μmol/L (18.3–29.8), p = 0.001]. However, the area under the receiver operating curves (AUROC) for the diagnosis of AMI by Citrulline was low: 0.68 (95% confidence interval = 0.58–0.78). No statistical difference was found in plasma I-FABP and plasma d-lactate concentrations between the AMI and control groups, with an AUROC of 0.44, and 0.40, respectively. In this large cross-sectional study, citrulline, I-FABP, and d-lactate failed to differentiate patients with AMI from patients with acute abdominal pain of another origin. Further research should focus on the discovery of new biomarkers.
