Background and aims: The enhanced liver fibrosis (ELF) score is a blood test that combines three markers linked to liver fibrosis. The utility of the ELF score has been demonstrated primarily in Western countries, but whether it is useful in areas with a high number of elderly people suffering from chronic liver disease has yet to be determined. Methods: This is a prospective study that included 373 consecutive patients who underwent a liver biopsy and had their ELF score measured on the same day. The diagnostic accuracy of the ELF score for liver fibrosis and the effect of age on the ELF score were investigated. Results: The median (interquartile) ELF scores in F0, F1, F2, F3, and F4 are 8.7 (8.2-9.2), 9.3 (8.8-10.0), 10.1 (9.4-10.7), 10.7 (9.9-11.2), and 12.0 (11.2-12.7), respectively. ELF scores increased with increasing liver fibrosis stage (p < 0.001). The diagnostic accuracy of the ELF score and FIB-4 for significant fibrosis (F2-4) and advanced fibrosis (F3-4) was comparable, but the ELF score had a higher diagnostic accuracy for cirrhosis (F4) than FIB-4. When patients were stratified by age of 60 years, the median ELF score did not differ by age in F2, F3, and F4. However, the median FIB-4 increased in patients with ≥60 years compared to those with <60 years in all fibrosis stages. Conclusions: ELF score has high diagnostic accuracy for liver fibrosis, regardless of age, and it could be used as a primary screening method.

UNASSIGNED: We have previously demonstrated high rates of chronic allograft hepatitis and fibrosis in liver transplant patients on long-term cyclosporine monotherapy. We subsequently changed practice to add low-dose prednisolone to maintenance treatment with tacrolimus post-transplant. The aim of the study was to assess the impact of the immunosuppression change on graft histopathology.
UNASSIGNED: Patients treated in this era (Tac + Pred, 2000-2009, N = 128) were compared to a historical cohort, who had been maintained on a steroid-free, cyclosporine-based regime (CSA-Only, 1985-1996, N = 129). Protocol liver biopsies and laboratory tests were performed five- and ten-years post-transplant in both groups.
UNASSIGNED: Compared to CSA-Only, the Tac + Pred cohort had significantly lower rates of chronic hepatitis (CH) at five (20% vs. 44%, p < 0.001) and ten (15% vs. 67%, p < 0.001) years post-transplant, with similar trends observed in inflammation and fibrosis at five years. The Tac + Pred cohort also had significantly lower hepatic transaminases and IgG levels and was less likely to be autoantibody positive at both time points. However, the degree of graft fibrosis at ten years did not differ significantly between eras (p = 0.356).
UNASSIGNED: Increased immunosuppression effectively reduced chronic allograft hepatitis and fibrosis at five years, suggesting it is an immunologically driven variant of rejection. However, there was no significant reduction in the degree of fibrosis at ten years, indicating a multifactorial origin for long term graft fibrosis.

BACKGROUND: Amyloidosis is a rare disorder that can be classified into various types, and the most common type is the systemic light chain type. The prognosis of this disease is extremely poor. In general, amyloidosis mainly affects the kidneys and heart and manifests as abnormal proliferation of clonal plasma cells. Cases in which the liver is the primary organ affected by amyloidosis, as in this report, are less common in clinical practice.
METHODS: A 62-year-old man was admitted with persistent liver dysfunction of unknown cause and poor treatment outcomes. His condition persisted, and he developed chronic liver failure, with severe cholestasis in the later stage that was gradually accompanied by renal injury. Ultimately, he was diagnosed with hepatic amyloidosis through liver biopsy and pathological examination.
CONCLUSIONS: Hepatic amyloidosis rarely occurs in the clinic, and liver biopsy and pathological examination can assist in the accurate and effective diagnosis of this condition.

UNASSIGNED: Primary hepatic epithelioid hemangioendothelioma (HEHE) is an extremely rare tumour of vascular origin with an incidence of <0.1 cases per 100,000 people worldwide.
UNASSIGNED: A 29-year-old female with the history of epigastric pain and unintentional weight loss (3 kg over six months) was referred for upper endoscopy. The examination was without visual pathological findings, but a rapid urease test was positive. First-line treatment with clarithromycin-containing triple therapy for Helicobacter pylori infection was given. After completion of eradication therapy, diffuse abdominal pain developed. An abdominal computed tomography (CT) showed multiple liver nodules. Three consecutive core liver biopsies were performed and were inconclusive. A subsequent surgical liver nodule resection was performed. Histopathology of the specimen revealed grade 2 hepatocellular carcinoma; bone scintigraphy was negative for metastasis. A multidisciplinary team (MDT) recommended giving the patient sorafenib, which was poorly tolerated. The histology was reviewed using immunohistochemistry staining at the request of the oncologist, which showed expression of CD31 and CD34. Based on clinical, morphological and immunohistochemistry findings, a diagnosis of hepatic epithelioid hemangioendothelioma was made. Based on the multidisciplinary team\'s findings, liver transplantation was indicated as the only curative treatment.
UNASSIGNED: Because of the rarity of this disease, combining clinical, radiological and histopathological methods as well as an MDT approach can help to reach the correct final diagnosis. As demonstrated in this clinical case, it is crucial to perform immunohistochemistry of a liver biopsy to confirm a HEHE diagnosis.
CONCLUSIONS: Hepatic epithelioid hemangioendothelioma is a rare vascular tumour that is often misdiagnosed and mismanaged.This case emphasises the critical importance of interdisciplinary teamwork and the use of non-invasive and invasive techniques to achieve a definitive diagnosis.

The type of liver cancer that occurs most frequently is hepatocellular carcinoma (HCC). The majority of cases of HCC are secondary to alcoholic cirrhosis or viral hepatitis. The presence of malignant cells with modest nuclear atypia that resemble normal hepatocytes and the lack of bare nuclei in the smears, which shows the neoplastic hepatocytes\' capacity, are characteristics of a well-differentiated HCC plasma membrane to tolerate smearing. We present the case of an 83-year-old male patient with a well-differentiated HCC, who had no etiological factors and no signs of alcohol cirrhotic liver, or any symptoms of liver disease which are the main causes of the HCC.

Liver biopsy is an important means of clinical diagnosis and treatment of liver diseases, but it is not easily accepted by patients because of its invasiveness. The most commonly employed liver biopsy approaches are percutaneous or transjugular. Endoscopic ultrasound-guided liver biopsy (EUS-LB), a newly emerging transjugular technique, has been widely studied and applied in recent years, but its application in China is less common. The EUS-LB has the advantages of high safety and comfort, simultaneous sampling of both liver lobes, and adequate sampling volume; however, it also has the disadvantages of high requirements for hardware, operators, and cost. This article reviews the clinical application of EUS-LB in accordance with pertinent research findings from recent years and discusses its advantages, disadvantages, and implementation feasibility.
肝活检是肝病临床诊疗的重要手段，因其有创性不易为患者接受。常用的肝活检主要有经皮或经颈静脉肝脏穿刺途径。超声内镜下肝脏穿刺活检(EUS-LB)作为新出现的肝脏穿刺技术，近年来得到较多的研究和应用，然而在国内开展较少。EUS-LB具有较高的安全性和舒适性、可同时肝脏双叶取样、有足够的取样量等优点，但也存在对硬件和操作者要求高、成本高等不足。现根据近年来的相关研究结果对EUS-LB在临床中的应用进行综述，探讨其优缺点及开展的可行性。.

BACKGROUND: Studies with large size samples on the liver histological changes of indeterminate phase chronic hepatitis B (CHB) patients were not previously conducted.
OBJECTIVE: To assess the liver histological changes in the indeterminate phase CHB patients using liver biopsy.
METHODS: The clinical and laboratory data of 1532 untreated CHB patients were collected, and all patients had least once liver biopsy from January 2015 to December 2021. The significant differences among different phases of CHB infection were compared with t-test, and the risk factors of significant liver histological changes were analyzed by the multivariate logistic regression analysis.
RESULTS: Among 1532 untreated CHB patients, 814 (53.13%) patients were in the indeterminate phase. Significant liver histological changes (defined as biopsy score ≥ G2 and/or ≥ S2) were found in 488/814 (59.95%) CHB patients in the indeterminate phase. Significant liver histological changes were significant differences among different age, platelets (PLTs), and alanine aminotransferase (ALT) subgroup in indeterminate patient. Multivariate logistic regression analysis indicated that age ≥ 40 years old [adjust odd risk (aOR), 1.44; 95% confidence interval (CI): 1.06-1.97; P = 0.02], PLTs ≤ 150 × 109/L (aOR, 2.99; 95%CI: 1.85-4.83; P < 0.0001), and ALT ≥ upper limits of normal (aOR, 1.48; 95%CI: 1.08, 2.05, P = 0.0163) were independent risk factors for significant liver histological changes in CHB patients in the indeterminate phase.
CONCLUSIONS: Our results suggested that significant liver histological changes were not rare among the untreated CHB patients in indeterminate phase, and additional strategies are urgently required for the management of these patients.

There is dramatically increased incidence of several liver diseases worldwide; thus, an unmet need to diagnose and stage these pathological entities heralds the wide application of liver biopsy (LB) techniques. The ways of LB are versatile, including percutaneous LB, transjugular LB, and more recently an approach of minimal invasiveness, that is, EUS-guided LB (EUS-LB). In this review article, we come to the conclusion that EUS-LB may serve as a feasible, reliable, and safe alternative to percutaneous LB and transjugular LB in terms of improved diagnostic yield, excellent sampling performance, and controlled adverse events among patients with focal, infiltrative, and parenchymal liver diseases. Furthermore, extensive efforts have been made to optimize and refine several technical pillars within EUS-LB modality such as the selection of needle size/type, priming manner of biopsy needle, and choice of pass/actuation technique, all of which aim at obtaining better specimen quantity and quality. Another advantageous aspect and unique property pertinent to EUS-guided modality indicate that multiple screening, surveillance, and intervention procedures can be combined into one single endoscopic session. Accordingly, some pilot studies have clarified the clinical usefulness by integrating EUS-LB with simultaneous measurement of portal pressure gradient or examination of liver stiffness. However, more studies, in particular, randomized controlled trials or real-world evidence, are practically warranted to elucidate the validity and safety of EUS-LB as a regular/routine part of managing liver diseases.

Bilhemia is a rare but potentially lethal condition representing abnormal communication and flow of bile into the bloodstream. We present a case of iatrogenic bilhemia after a percutaneous liver biopsy in a patient with cholangiocarcinoma. The bilio-venous fistula was visualized with percutaneous cholangiography and successfully embolized using coils and the liquid embolic agent Onyx. To our knowledge, this is the first report of using Onyx for the embolization of a bilio-venous fistula.

Percutaneous ultrasound has been a longstanding method in the diagnostics and interventional procedures of liver diseases. In some countries, its use is restricted to radiologists, limiting access for other clinicians, such as gastroenterologists. Endoscopic ultrasound, as a novel technique, plays a crucial role in diagnosis and treatment of digestive diseases. However, its use is sometimes recommended for conditions where no clear advantage over percutaneous ultrasound exists, leaving the impression that clinicians sometimes resort to an endoscopic approach due to the unavailability of percutaneous options.
