AI Article Synopsis

  • * Real-time shear wave elastography (SWE) was used to measure liver stiffness and fibrosis stages in patients, with most showing low fibrosis levels and only one showing F3 fibrosis due to recurrent cholangitis.
  • * The findings suggest that while liver fibrosis is rare in patients without complications post-surgery, those with long-term issues should be regularly checked using SWE to prevent overlooking potential liver cirrhosis.

Article Abstract

Purpose: Liver fibrosis is not thought to occur in patients with no adverse events after surgery for congenital biliary dilatation (CBD). However, this speculation is not supported by any reports. Real-time shear wave elastography (SWE) is a noninvasive, ultrasound-based technique to evaluate liver stiffness. We aimed to clarify the presence of liver fibrosis using SWE in patients who had undergone surgery for CBD.

Methods: We included patients who underwent radical surgery for CBD, who were followed up until March 2022, and have been performed with SWE at our institution from April 2021 to March 2022. Liver stiffness was evaluated using SWE, and liver fibrosis stages (F0-F4; METAVIR scoring) were determined based on the previously reported associations between liver stiffness and liver fibrosis. We assessed the general condition of each patient and performed routine blood investigations on the same day as SWE.

Results: Two out of 20 patients had long-term complications (intrahepatic stones without symptoms [n = 1], recurrent cholangitis [n = 1]). The median hepatic shear wave propagation velocity was 1.26 (range, 1.12-1.60) m/s in all cases. The estimated liver fibrosis stage was ≤F1 in patients without long-term complications. In patient with recurrent cholangitis, the hepatic shear wave propagation velocity was 1.60 m/s, and the estimated liver fibrosis stage was F3.

Conclusion: Liver fibrosis tended not to occur in patients with no complications after surgery for CBD. However, patients with long-term postoperative complications, such as cholangitis, should be examined using SWE so as not to overlook liver cirrhosis.

Coagulopathy in acute liver failure.

Best Pract Res Clin Gastroenterol

December 2024

Department of Hepatology, Postgraduate Institute of Medical Education and Research, Chandigarh, India. Electronic address:

Acute liver failure (ALF) is a rare but rapidly progressing syndrome, marked by severe liver dysfunction and altered mental status. While definitions of ALF vary across different guidelines, with timelines ranging from 4 to 26 weeks between jaundice onset and encephalopathy, the key defining features remain encephalopathy and coagulopathy. Elevated coagulation markers, particularly prothrombin time and international normalized ratio, have traditionally been associated with bleeding risks.

Objectives: Investigate the consequences of the histological progression of metabolically associated steatohepatitis (MASH) and fibrosis on long-term survival after bariatric surgery.

Methods: From 1994 to 2021, 3028 patients at the University Hospital of Lille were prospectively included. Baseline liver biopsies were systematically performed with proposed follow-up biopsies 1 year after surgery, mainly in MASH patients.

Bone quality analysis of the mandible in alcoholic liver cirrhosis: Anatomical, microstructural, and microhardness evaluation.

Bone

December 2024

Center of Bone Biology, Institute for Anatomy, Faculty of Medicine, University of Belgrade, Serbia; Dr Subotica starijeg 4, 11000 Belgrade, Serbia. Electronic address:

Objectives: Alcoholic bone disease has been recognized in contemporary literature as a systemic effect of chronic ethanol consumption. However, evidence about the specific influence of alcoholic liver cirrhosis (ALC) on mandible bone quality is scarce. The aim of this study was to explore microstructural, compositional, cellular, and mechanical properties of the mandible in ALC individuals compared with a healthy control group.

Metabolomic Changes Associated With the Change in HVPG After DAAs Therapy in HCV Cirrhotic Patients.

Liver Int

January 2025

Unidad de Infección Viral e Inmunidad, Centro Nacional de Microbiología (CNM), Instituto de Salud Carlos III (ISCIII), Madrid, Spain.

Background And Aims: In response to direct-acting antivirals (DAAs) therapy, patients who experience a decrease in hepatic venous pressure gradient (HVPG) considerably reduce liver complications and have increased survival. This study aimed to assess the metabolomic changes associated with the changes in HVPG from the start of DAA therapy until 48 weeks after effective DAA therapy in patients with advanced HCV-related cirrhosis.

Methods: We carried out a multicenter longitudinal study in 31 patients with advanced hepatitis C virus (HCV)-related cirrhosis.
