Colorectal Cancer and Precursor Lesion Prevalence in Adults Younger Than 50 Years Without Symptoms.

Importance: Incidence of colorectal cancer (CRC) is increasing among younger adults. However, data on precursor lesions in patients who are asymptomatic, especially those aged younger than 50 years, are lacking.

Objective: To analyze the prevalence and number needed to screen (NNS) for adenomas, advanced adenomas, and serrated lesions, as well as the incidence of CRC in patients older than age 20 years.

Predicting survival in patients with 'non-high-risk' acute variceal bleeding receiving β-blockers+ligation to prevent re-bleeding.

Background & Aims: Pre-emptive transjugular intrahepatic portosystemic shunt (TIPS) is the treatment of choice for high-risk acute variceal bleeding (AVB; i.e., Child-Turcotte-Pugh [CTP] B8-9+active bleeding/C10-13).

Detection of high-risk polyps at screening colonoscopy indicates risk for liver and biliary cancer death.

Background: Hepatobiliary cancers share risk factors with colorectal cancer (CRC), but there are no combined screening programs for these conditions.

Aims: The aim of this study was to assess whether patients with high-risk colonic polyps are more likely to die from liver related tumors than patients with a negative colonoscopy.

Methods: In this retrospective analysis of mortality data, Austrian screening participants were included.

Austrian consensus on the diagnosis and management of portal hypertension in advanced chronic liver disease (Billroth IV).

The Billroth IV consensus was developed during a consensus meeting of the Austrian Society of Gastroenterology and Hepatology (ÖGGH) and the Austrian Society of Interventional Radiology (ÖGIR) held on the 26th of November 2022 in Vienna.Based on international recommendations and considering recent landmark studies, the Billroth IV consensus provides guidance regarding the diagnosis and management of portal hypertension in advanced chronic liver disease.

Alcohol-related liver disease phenotype impacts survival after an acute variceal bleeding episode.

Background & Aims: Alcohol-related hepatitis (AH) encompasses a high mortality. AH might be a concomitant event in patients with acute variceal bleeding (AVB). The current study aimed to assess the prevalence of AH in patients with AVB and to compare the clinical outcomes of AH patients to other alcohol-related liver disease (ALD) phenotypes and viral cirrhosis.

Chylous Ascites as the Main Clinical Symptom of a Infection in an Immigrant from Bosnia-Herzegovina.

Unlabelled: Extraintestinal strongyloidiasis is rare in patients without immunosuppression. We describe the first case of chylous ascites as a result of strongyloidiasis. Alcohol cessation, diuretic therapy and repeated paracentesis did not lead to improvement of refractory chylous ascites with positive nucleic acid amplification test indicative of infection.

Hepatic encephalopathy is not a contraindication to pre-emptive TIPS in high-risk patients with cirrhosis with variceal bleeding.

Background: A pre-emptive transjugular intrahepatic portosystemic shunt (pTIPS) reduces mortality in high-risk patients with cirrhosis (Child-Pugh C/B+active bleeding) with acute variceal bleeding (AVB). Real-life studies point out that <15% of patients eligible for pTIPS ultimately undergo transjugular intrahepatic portosystemic shunt (TIPS) due to concerns about hepatic encephalopathy (HE). The outcome of patients undergoing pTIPS with HE is unknown.

Evolution of SARS-CoV-2 Key Mutations in Vienna Detected by Large Scale Screening Program.

Currently countries across the globe are preparing for the fourth wave of SARS-CoV-2 infections, which is mainly driven by the rapid spread of novel SARS-CoV-2 variants. Austria and, in particular, the capital city of Vienna, witnessed a disproportionally steep rise in SARS-CoV-2 infection rates during the last wave of infections. By the end of January 2021, the government of Vienna launched an innovative, state-wide SARS-CoV-2 screening program based on PCR analysis of self-collected mouthwash samples.

Impact of restrictions due to COVID-19 on a quality-assured screening colonoscopy program.

On February 25, 2020, the first patient was diagnosed with COVID-19 in Austria. On March 16, 2020, the Austrian government imposed restrictions and subsequently the Austrian Medical Association recommended minimizing screening examinations in compliance with government restrictions. The aims of this study were to evaluate the impact of this recommendation on the number of colonoscopies performed weekly and detection of non-advanced adenomas, advanced adenomas (AA) and colorectal cancer (CRC) and to calculate how many undetected adenomas could have developed into CRC.

Noninvasive Diagnosis of Portal Hypertension in Patients With Compensated Advanced Chronic Liver Disease.

Introduction: We aimed to explore the prevalence of portal hypertension in the most common etiologies of patients with compensated advanced chronic liver disease (cACLD) and develop classification rules, based on liver stiffness measurement (LSM), that could be readily used to diagnose or exclude clinically significant portal hypertension (CSPH) in clinical practice.

Methods: This is an international cohort study including patients with paired LSM/hepatic venous pressure gradient (HVPG), LSM ≥10 kPa, and no previous decompensation. Portal hypertension was defined by an HVPG >5 mm Hg.

Combination of phosphodiesterase-5-inhibitors and beta blockers improves experimental portal hypertension and erectile dysfunction.

Background & Aims: Phosphodiesterase-5 inhibitors (PDE-5-I) are used for treatment of erectile dysfunction (ED), which is common in patients with cirrhosis. They may improve portal hypertension (PH), but contradictory data on efficacy and side-effects have been reported. Non-selective beta blockers (NSBB) reduce portal pressure, but might aggravate ED.

Rebleeding and mortality risk are increased by ACLF but reduced by pre-emptive TIPS.

Background & Aims: The relationship between acute-on-chronic liver failure (ACLF) and acute variceal bleeding (AVB) is poorly understood. Specifically, the prevalence and prognosis of ACLF in the context of AVB is unclear, while the role of transjugular intrahepatic portosystemic shunt (TIPS) in the management in patients with ACLF has not been described to date.

Methods: A multicenter, international, observational study was conducted in 2,138 patients from 34 centers between 2011 and 2015.

Anemia and iron deficiency in compensated and decompensated cirrhosis: Prevalence and impact on clinical outcomes.

Background And Aim: Iron deficiency anemia (IDA)is the leading cause of anemia worldwide. Data on prevalence and clinical impact of anemia in cirrhosis are scarce. Aim was to report on the following:(i) prevalence of anemia and IDA in cirrhosis and (ii) its possible impact on clinical outcomes.

Impact of HSD17B13 rs72613567 genotype on hepatic decompensation and mortality in patients with portal hypertension.

Background & Aims: The loss-of-function rs72613567 T > TA-variant in the 17β-hydroxysteroid dehydrogenase 13 (HSD17B13) gene might protect from alcoholic and non-alcoholic fatty liver disease (ALD/NAFLD) and associated fibrosis/cirrhosis. We investigated the impact of the T > TA-variant on hepatic decompensation and mortality and investigated its implications on retinol and sex steroid metabolism in patients who had already developed advanced chronic liver disease (ACLD).

Methods: Retrospective analysis in prospectively characterized patients with viral hepatitis- and ALD/NAFLD-induced portal hypertension (hepatic venous pressure gradient (HVPG) ≥ 6 mmHg) diagnosed at the Medical University of Vienna.

Non-invasive diagnosis of cirrhosis and long-term disease monitoring by transient elastography in patients with Wilson disease.

Background & Aims: The value of liver stiffness measurement (LSM) by transient elastography (TE) for non-invasive fibrosis staging and disease monitoring has not been established in patients with Wilson disease (WD).

Methods: Liver stiffness measurement by TE and non-invasive fibrosis scores (APRI, FIB-4) were analysed from 188 WD patients with liver biopsy (LBX). Longitudinal LSM was performed in 128 (68.

The impact of hepatic steatosis on portal hypertension.

Background And Aims: Studies in animal models have suggested that hepatic steatosis impacts on portal pressure, potentially by inducing liver sinusoidal endothelial dysfunction and thereby increasing intrahepatic resistance. Thus, we aimed to evaluate the impact of hepatic steatosis on hepatic venous pressure gradient (HVPG) in patients with chronic liver disease.

Method: 261 patients undergoing simultaneous HVPG measurements and controlled attenuation parameter (CAP)-based steatosis assessment were included in this retrospective study.

Impact of adenoma detection rate on detection of advanced adenomas and endoscopic adverse events in a study of over 200,000 screening colonoscopies.

Background And Aims: Adenoma detection rate (ADR) is the best established quality parameter for screening colonoscopy. Guidelines recommend a target ADR >25% because previous studies have shown that patients of endoscopists with higher ADRs have a lower risk of postcolonoscopy interval cancers. However, studies have shown that improvement in ADR mainly results in increased detection of clinically irrelevant nonadvanced adenomas (NAAs).

Short- and long-term effects of transarterial chemoembolization on portal hypertension in patients with hepatocellular carcinoma.

Background: Transarterial chemoembolization (TACE) affects hepatic perfusion, and might have an impact on portal pressure in patients with hepatocellular carcinoma (HCC).

Objective: The objective of this article is to report the secondary outcome "hepatic hemodynamics" from the AVATACE trial, a prospective randomized, placebo-controlled trial on the efficacy of conventional TACE in combination with bevacizumab or placebo.

Methods: Hepatic venous pressure gradient (HVPG) was measured at baseline (prior to first TACE), within nine days ("acute effects"), two months ("intermediate effects") and six months ("long-term effects") after the first TACE.

Performance of Controlled Attenuation Parameter in Patients with Advanced Chronic Liver Disease and Portal Hypertension.

Background: Liver stiffness (LS) measured by vibration-controlled transient elastography (VCTE) is influenced by liver fibrosis and hepatic perfusion pressure. VCTE-based controlled attenuation parameter (CAP) is a noninvasive marker for hepatic steatosis (HS).

Aims: To investigate the diagnostic performance of CAP in patients with advanced chronic liver disease (ACLD)/portal hypertension (PHT: hepatic venous pressure gradient (HVPG) ≥ 6 mmHg).

Transjugular aspiration liver biopsy performed by hepatologists trained in HVPG measurements is safe and provides important diagnostic information.

Background: Transjugular liver biopsy (TJLB) represents an alternative to percutaneous liver biopsy especially in patients with impaired coagulation and ascites.

Aims: To describe safety and diagnostic yield of aspiration TJLB performed by hepatologists experienced in hepatic venous pressure gradient (HVPG) measurements.

Methods: 445 TJLB of 399 patients between 01/2007-12/2016 were retrospectively assessed.

Impact of high-volume, intermediate-volume and low-volume bowel preparation on colonoscopy quality and patient satisfaction: An observational study.

Background: Although optimal bowel preparation is essential for high-quality screening colonoscopy, documentation of preparation quality, patient satisfaction and adherence is scarce.

Aim: The aim of this article is to compare low-volume (LV, 300 ml sodium picosulfate), intermediate-volume (IV, 2 l polyethylene glycol, PEG + ascorbic acid and sodium ascorbate), and high-volume (HV, 4 l PEG) purgatives.

Results: A total of 5000 individuals (50.

von Willebrand Factor Antigen Predicts Outcomes in Patients after Liver Resection of Hepatocellular Carcinoma.

Background/aims: von Willebrand factor antigen (vWF-Ag) is a noninvasive predictor of portal hypertension that serves as a negative prognostic marker in various malignancies. Increased portal hypertension is associated with higher postoperative morbidity and decreased survival after hepatectomy. The purpose of this study was to determine the correlation between vWF-Ag, postoperative morbidity and oncological outcome.

Management of Coagulopathy during Bleeding and Invasive Procedures in Patients with Liver Failure.

Alterations in hemostasis are a characteristic feature of advanced liver disease. Patients with coagulopathy of advanced liver disease are prone to bleedings and also thromboembolic events. Under stable conditions, cirrhosis patients show alterations in both pro- and anticoagulatory pathways, frequently resulting in a rebalanced hemostasis.
