Abstract
INTRODUCTION Liver biopsy is a technique frequently performed in clinical practice. However, the recommended surveillance period after the procedure is not established in the guidelines. The aim of this study was to assess the safety and patient satisfaction of hospital discharge 2 h after a percutaneous liver biopsy. METHODS Prospective monocentric study which included all patients who underwent percutaneous liver biopsy between December 2020 and November 2022. Individuals were discharged 2 h after the procedure according to a protocol that was implemented in our institution. RESULTS A total of 200 patients were included, the majority male (52.0%), with a median age of 52 years old (interquartile range (IQR) 40-60). Forty-two (21.0%) individuals had mild adverse events at the time of or within 2 h of the procedure. Most (90.4%) occurred in the first hour after the liver biopsy. Only 5 (2.5%) patients were kept under observation for 4 h due to abdominal/shoulder pain. There were no serious complications and no patient required subsequent admission. The majority of patients reported being satisfied/very satisfied (99.4%) and felt safe (98.9%) with this protocol. Most of the individuals showed a preference for early hospital discharge (97.3%). CONCLUSION We showed that patients requiring percutaneous liver biopsy can be safely discharged 2 h after the procedure.

Abstract
PURPOSE The risk of posthepatectomy liver failure (PHLF) remains an important concern following major liver resection. Assessment of future remnant liver function (FRLF) by hepatobiliary scintigraphy has shown its significance to prevent PHLF after major liver resection in adults with a threshold value of FRLF greater than 2.7%/min per m2. However, such data for pediatric patients were not published. METHODS A total of 77 pediatric patients with liver tumors who underwent 1-stage liver resection were included in this study. Assessment of FRLF, future remnant liver volume (FRLV), and the ratio of remnant liver volume to body weight (RLV-BWR) was performed before the surgery. RESULTS All patients had RLV-BWR values of more than 0.5%/kg. Future remnant liver volume values ranged from 19% to 89%, and FRLF values ranged from 1.8% to 31.8%/min per m2. Only 7 of 77 patients had FRLV values less than 25%, but their FRLF values exceeded 2.7%/min per m2. Two patients developed grade A and grade B PHLF. CONCLUSION Future remnant liver volume and the RLV-BWR can be used in most pediatric patients for the assessment of liver before hepatectomy. According to our data, implementation of FRLF assessment using hepatobiliary scintigraphy can be most beneficial for children with FRLV of less than 25%. The cutoff value of FRLV greater than 25% can be slightly decreased with minimal risk of developing PHLF. However, to establish a new cutoff value for FRLV in children, further prospective studies including larger numbers of patients with FRLV of less than 25% are needed.

Abstract
The prevention and management of bleeding and thrombosis in patients with cirrhosis poses several difficult clinical questions. These Clinical Practice Guidelines have been developed to provide practical guidance on debated topics, including current views on haemostasis in liver disease, controversy regarding the need to correct thrombocytopenia and abnormalities in the coagulation system in patients undergoing invasive procedures, and the need for thromboprophylaxis in hospitalised patients with haemostatic abnormalities. Multiple recommendations in this document are based on interventions that the panel feels are not useful, even though widely applied in clinical practice.

Abstract
Objective: We aim to evaluate the effects of different recovery positions on the adverse events and the patient acceptability in those who underwent percutaneous liver biopsy (PLB). Methods: A literature search was conducted in the Cochrane Library, Embase, Scopus, PubMed, CNKI, Sinomed, and Wanfang databases. The time for the article extraction was until July 2020. The articles were screened by two independent researchers, together with the bias risk evaluation and data extraction. The RevMan 5.4 software was utilized for the metaanalysis. Results: Finally, two articles involving 180 subjects were eligible for this study. Metaanalysis showed that at T0, the alternation between right-side and combined position (CRP) would induce an elevation of post-PLB pain compared with the dorsal/supine position (SRP) [WMD = -2.00, 95% CI (-3.54, -0.47), p = 0.01]. There were no statistical differences in the postoperative pain among the CRP, SRP, and right-side position (RRP). The patient acceptability of SRP and RRP was higher than that of the CRP. Finally, two eligible studies were included, which showed no incidence of pneumothorax and abdominal bleeding. Conclusions: CRP would induce post-PLB pain at T0. SRP was the most acceptable position for the cases that underwent PLB. There were no statistical differences in the incidence of pneumothorax and abdominal bleeding.

Abstract
BACKGROUND In current general practice, elevated serum concentrations of liver enzymes are still regarded as an indicator of non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH). In this study, we analyzed if an adjustment of the upper limit of normal (ULN) for serum liver enzymes can improve their diagnostic accuracy. METHODS Data from 363 morbidly obese patients (42.5 ± 10.3 years old; mean BMI: 52 ± 8.5 kg/m2), who underwent bariatric surgery, was retrospectively analyzed. NAFL and NASH were defined histologically according to non-alcoholic fatty liver activity score (NAS) and according to steatosis activity fibrosis (SAF) score for 2 separate analyses, respectively. RESULTS In 121 women (45%) and 45 men (46%), elevated values for at least one serum parameter (ALT, AST, γGT) were present. The serum concentrations of ALT (p < 0.0001), AST (p < 0.0001) and γGT (p = 0.0023) differed significantly between NAFL and NASH, irrespective of the applied histological classification method. Concentrations of all 3 serum parameters correlated significantly positively with the NAS and the SAF score, with correlation coefficients between 0.33 (ALT/NAS) and 0.40 (γGT/SAF). The area under the curves to separate NAFL and NASH by liver enzymes achieved a maximum of 0.70 (ALT applied to NAS-based classification). For 95% specificity, the ULN for ALT would be 47.5 U/L; for 95% sensitivity, the ULN for ALT would be 17.5 U/L, resulting in 62% uncategorized patients. CONCLUSION ALT, AST, and γGT are unsuitable for non-invasive screening or diagnosis of NAFL or NASH. Utilizing liver enzymes as an indicator for NAFLD or NASH should generally be questioned.

Abstract
ABSTRACT The ability of ultrasound elastography to diagnose focal liver lesions and determine their prognoses including hepatocellular carcinoma (HCC) is unclear. At present, radiofrequency ablation and liver resection are the most common treatments for HCC. However, the survival rate remains disappointing because of recurrences and postoperative liver failure, necessitating the development of noninvasive approaches. There is currently no systematic definition of an elastic technique for measuring liver stiffness to predict the recurrence of HCC after radiofrequency ablation and postoperative liver failure. In this review, recent advances in ultrasound elastography for the diagnosis and prognosis of focal liver lesions are discussed including HCC.

Abstract
INTRODUCTION Ultrasound-guided percutaneous liver biopsy is considered the technique of choice for the histological diagnosis of space-occupying lesions, given its high level of safety and diagnostic performance. However, since it is an invasive diagnostic procedure, complications can occur. Various clinical and radiological parameters have been analyzed as factors related with the efficacy of the technique or with its complications; however, the results have been contradictory. Thus, we aimed to evaluate the impact of various risk factors on the efficacy and complications of ultrasound-guided percutaneous liver biopsy in the diagnosis of space-occupying lesions in ordinary clinical practice. MATERIAL AND METHODS This retrospective observational study included all patients who underwent real-time ultrasound-guided percutaneous biopsies of space-occupying liver lesions with the free-hand technique between December 2012 and February 2018 in the diagnostic imaging department at the Hospital Clínico Universitario de Santiago de Compostela. We analyzed the following risk factors: location of the lesion in upper liver segments (II, IVa, VII, or VIII); proximity to the liver capsule, distance from the skin > 100mm, interposition of osseus or vascular structures, inability to go through healthy parenchyma, and lack of patient cooperation during the procedure. Efficacy was analyzed in terms of the number of cylinders obtained and the percentage of adequate biopsies; safety was analyzed in terms of the percentage of complications, which were classified as major or minor. RESULTS We included 295 biopsies in 278 patients (median age, 69 years; 64.1% male; 44.7% had prior neoplasms). In 61.4%, the biopsy was indicated for the initial diagnosis; 82.4% of biopsies were done in hospitalized patients, and 65% of the lesions were located in the right liver lobe. The median number of cylinders obtained was 3 (range 1-6); 91.2% of the biopsies were adequate and 92.2% were considered clinically useful. These percentages did not differ significantly according to the presence of risk factors. Complications occurred in 10 (3.4%) patients. Complications were considered major in 3 (0.9%) patients (2 (0.6%) bleeding complications and 1 (0.3%) infectious complication) and minor in 7 (2.4%). The percentage of complications was significantly higher in patients who did not cooperate during the procedure (p=0.04). CONCLUSIONS Ultrasound-guided percutaneous liver biopsy is an efficacious and safe technique for the histological diagnosis of space-occupying liver lesions. Our results confirm the increased rate of complications when patients fail to cooperate during the procedure.

Abstract
INTRODUCTION the percutaneous hepatic biopsy is a necessary procedure for the diagnosis of liver diseases which can cause complications and psychological discomfort for the patient. AIMS to determine the safety profile of propofol in percutaneous hepatic biopsy, the complications of the technique per se and patients satisfaction once completed. METHODS a retrospective observational study was performed via the acquisition of data of tolerance and perceived quality by the patients using a transversal survey. RESULTS ninety-seven patients were included with an average propofol dose of 170.46 mg. Of the complications resulting from the sedation, there were six slight desaturations (6.2 %) resolved with a forehead maneuver (50 %) or cessation of the propofol infusion pump (50 %) and eleven hypotension episodes (11.3 %) resolved without intervention (82.82 %) or with fluid replacement (18.18 %). Of the complications resulting from the technique, there were three cases of early-onset pain (3.1 %) and one delayed (1.03 %); all were resolved with 1 g of intravenous paracetamol. All patients were discharged with oral tolerance and without the need for analgesia 24 hours after the procedure. General satisfaction, as well as psychological discomfort, were evaluated as "very good/excellent" in 100 % of the patients. DISCUSSION propofol demonstrated a favorable safety profile in hepatic biopsy, aiding in the ultimate success of the procedure and tolerance for the patient. We propose the expansion of the use of sedation with propofol to this procedure.

Abstract
Liver biopsy is required when clinically important information about the diagnosis, prognosis or management of a patient cannot be obtained by safer means, or for research purposes. There are several approaches to liver biopsy but predominantly percutaneous or transvenous approaches are used. A wide choice of needles is available and the approach and type of needle used will depend on the clinical state of the patient and local expertise but, for non-lesional biopsies, a 16-gauge needle is recommended. Many patients with liver disease will have abnormal laboratory coagulation tests or receive anticoagulation or antiplatelet medication. A greater understanding of the changes in haemostasis in liver disease allows for a more rational, evidence-based approach to peri-biopsy management. Overall, liver biopsy is safe but there is a small morbidity and a very small mortality so patients must be fully counselled. The specimen must be of sufficient size for histopathological interpretation. Communication with the histopathologist, with access to relevant clinical information and the results of other investigations, is essential for the generation of a clinically useful report.

Abstract
Focal liver lesions (FLLs) are a common finding during routine abdominal ultrasound (US). The differential diagnosis between diverse types of FLLs, especially between benign and malignant ones, is extremely important and can often be particularly challenging. Radiological techniques with contrast administration and/or liver biopsy are mostly necessary for establishing diagnosis, but they have several contraindications or complications. Due to limitations of these tools, there is urgent and still unmet need to develop a first line, non-invasive and simple method to diagnose FLLs. Elastography is an US-based imaging modality that provides information about the physical parameter corresponding to the tissue stiffness and can be considered a virtual biopsy. Several elastographic approaches have been developed, such as transient elastography, strain imaging and share wave imaging, which include point shear wave elastography and 2D shear wave elastography. These tools are already in use for evaluating liver fibrosis and in the assessment of focal lesions in other organs, like breast and thyroid gland. This review aims to assess the current evidence of different techniques based on elastography in the setting of FLLs, in order to evaluate accuracy, limitations and future perspectives. In particular, we focused on two contexts: the ability of discriminating between benign and malignant lesions, especially hepatocellular carcinoma and liver metastasis, and the surveillance after percutaneous therapy. This could have a high clinical impact making elastography crucial to identify the appropriate management of FLLs.

Abstract
BACKGROUND/OBJECTIVE Percutaneous biopsy (PB) and transjugular liver biopsy (TJLB) are 2 main ways of obtaining liver tissue. We evaluated the indications, success rate, tissue yield, and complications of TJLB in comparison to PB in children. METHODS Electronic records of children undergoing liver biopsy (LB) were reviewed. Clinico laboratory data including indication, type of biopsy, complications, and tissue yield (length and number of complete portal tracts [CPT]) were noted. RESULTS Five hundred forty LB (indication: neonatal cholestasis [42.9%], chronic liver disease [43.7%], liver failure [3.7%], focal lesions [3.3%] and others [6.3%]) were done. Four hundred seventy-three were PB (317 boys, 14 [1--216] months) done by percussion (322 [68%]), real-time ultrasound guidance (125 [26.4%]), or plugged method [26 (5.5%)]. Sixty-seven (12.4%) were TJLB [38 boys, 140 (24--216) months], done in patients with contraindications for PB. Technical success (67/68 vs 473/473; P = 0.7) and complications (4 [6%]; vs 15 [3.3%]; P = 0.2) of TJLB and PB were similar. Major complications (0.5%) included supraventricular tachycardia (n = 1) in TJLB and hemoperitoneum (n = 2) in PB. Tissue yield of TJLB was poorer in terms of length (1.0 [0.2--2.0] vs 1.1 [0.4--2.1] cm; P < 0.001), CPT (4 [0--9] vs 5 [2--17]; P < 0.001) and adequacy for reporting (56/67 vs 459/473; P < 0.001). Biopsy yield of <6 CPT was predicted by cirrhosis at histology and TJLB. No factor identified risk of complications with LB. CONCLUSIONS LB is a safe procedure and only 12% children require TJLB because of contraindications of PB. Technical success and complications are similar but tissue yield is poorer in TJLB than PB. Presence of cirrhosis and TJLB adversely affected tissue yield.

The efficacy and safety of endoscopic ultrasound-guided liver biopsy versus percutaneous liver biopsy in patients with chronic liver disease: a retrospective single-center study. J Ultrasound 2020; 23:157-167. [PMID: 32141043 DOI: 10.1007/s40477-020-00436-z] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Accepted: 02/15/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND AND AIMS There is limited literature on endoscopic ultrasound-guided liver biopsy (EUS-LB), a new method of obtaining liver biopsy (LB). METHODS We conducted a retrospective study of the efficacy and safety of EUS-LB compared to percutaneous liver biopsy (PC-LB) in patients with chronic liver disease at our center between January 2018 and August 2019. RESULTS Thirty patients underwent EUS-LB and 60 patients underwent PC-LB were identified (median follow-up post-LB was 8 days; interquartile range (IQR), 3-5 days). The median number of portal tracts was significantly higher in the PC-LB group (13 vs. 5; P < 0.0001). A histologic diagnosis was established in 93% of the EUS-LB group, compared to 100% in the PC-LB group (P = 0.841). Patients in EUS-LB group had significantly shorter hospital stay (median time of hospital stay was 3 vs. 4.2 h in the EUS-LB vs. PC-LB group, respectively; P = 0.004) and reported less pain compared to PC-LB group (median pain score was 0 vs. 3.5; P = 0.0009). EUS-LB were performed using a 19-gauge (n = 27) or 22-gauge (n = 3); there was a tendency towards higher number of portal tracts in the 22- vs. the 19-gauge needle group (6 vs. 5; P = 0.501). No patient in either group had significant adverse events such as bleeding or death. CONCLUSION EUS-LB is safe and is associated with less pain, shorter hospital stay, and high diagnostic yield (93%) compared to PC-LB. Randomized trials are needed to standardize the utility of EUS-LB.

Subgroup analysis of the predictive ability of aspartate aminotransferase to platelet ratio index (APRI) and fibrosis-4 (FIB-4) for assessing hepatic fibrosis among patients with chronic hepatitis C. JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2019; 53:542-549. [PMID: 31831303 DOI: 10.1016/j.jmii.2019.09.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 08/25/2019] [Accepted: 09/01/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND There are many laboratory indices to assess liver fibrosis. Aspartate aminotransferase to platelet ratio index (APRI) and fibrosis-4 (FIB-4) index have been used as well-known serum markers of liver fibrosis. With the increasing use of non-invasive fibrosis assessment, it is important to recognize the limitations of these tests. The factors influencing the diagnostic accuracy to evaluate liver fibrosis are not well-established. This study aimed to perform a subgroup analysis of the predictive ability of laboratory indices. METHODS Overall, 113 patients with chronic hepatitis C infection who underwent liver biopsy were retrospectively examined. The histological assessment of liver fibrosis was performed using the METAVIR scoring system, and the values of several laboratory tests were also evaluated on the same day. We categorized our study population by treatment status, body mass index (BMI), and age. RESULTS The two laboratory indices APRI and FIB-4 index could predict advanced (F3-4) liver fibrosis and cirrhosis (F4), with the area under the receiver operating characteristic curve (AUROC) > 0.8 and accuracy >70%. The AUROCs and accuracies were higher among patients with sustained virological response (SVR) than among those without SVR. A higher predictive ability was also observed among patients with BMI <25 kg/m2. Age did not appear to affect liver fibrosis predictability. CONCLUSIONS The laboratory indices APRI and FIB-4 index exhibit good diagnostic performance for determining advanced fibrosis and cirrhosis among patients with hepatitis C infection. The diagnostic accuracy appears better among patients with SVR and those with BMI <25 kg/m2.

Abstract
The role of liver biopsy in the diagnosis of hepatocellular carcinoma (HCC) has been challenged over time by the ability of imaging techniques to characterize liver lesions in patients with known cirrhosis. In fact, in the diagnostic algorithm for this tumor, histology is currently relegated to controversial cases. Furthermore, the risk of complications, such as tumor seeding and bleeding, as well as inadequate sampling have further limited the use of liver biopsy for HCC management. However, there is growing evidence of prognostic and therapeutic information available from microscopic and molecular analysis of HCC and, as the information content of the tissue sample increases, the advantages of liver biopsy might modify the current risk/benefit ratio. We herein review the role and potentiality of liver biopsy in the diagnosis and management of HCC. As the potentiality of precision medicine comes to the management of HCC, it will be crucial to have rapid pathways to define prognosis, and even treatment, by identifying the patients who could most benefit from target-driven therapies. All of the above reasons suggest that the current role of liver biopsy in the management of HCC needs substantial reconsideration.

Abstract
Aperture domain model image reconstruction (ADMIRE) is a useful tool to mitigate ultrasound imaging artifacts caused by acoustic clutter. However, its lengthy run-time impairs its usefulness. To overcome this drawback, we evaluated the reduced model methods with otherwise similar performance to ADMIRE. We also assessed other approaches to speed up ADMIRE, including the use of different levels of short-time Fourier transform (STFT) window overlap and examining the degrees of freedom of the model fit. In this study, we conducted an analysis of the reduced models, including those using Gram-Schmidt orthonormalization (GSO), singular value decomposition (SVD), and independent component analysis (ICA). We evaluated these reduced models using the data from simulations, experimental phantoms, and in vivo liver scans. We then tested ADMIRE's performance using full, GSO, SVD, and ICA-fourth-order blind identification (ICA-FOBI) models. The results from simulations, experimental phantoms, and in vivo data indicate that a model reduced using the ICA-FOBI method is the most promising for accelerating ADMIRE implementation. In the in vivo liver data, the improvements in contrast relative to delay-and-sum (DAS) using a full model, GSO, SVD, and ICA-FOBI models are 6.29 ± 0.25 dB, 11.88 ± 0.90 dB, 9.01 ± 0.67 dB, and 6.36 ± 0.27 dB, respectively; whereas, the contrast-to-noise ratio (CNR) improvement values in the same order are 0.04 ± 0.06 dB, -1.70 ± 0.17 dB, -1.51 ± 0.19 dB, and 0.12 ± 0.07 dB, respectively. The implementation of ADMIRE using the reduced model methods can decrease ADMIRE's computational complexity over three orders of magnitude. The use of a 50% STFT window overlap reduces ADMIRE's serial run time by more than one order of magnitude without any remarkable loss of image quality, when compared to the use of a 90% window overlap used previously. Based on these findings, a combination of the ICA-FOBI model and the use of a 50% STFT window overlap makes the ADMIRE algorithm more computationally efficient.

Abstract
Background Shear wave elastography (SWE) imaging have been proposed for characterization of focal liver lesions. We conducted a meta-analysis to evaluate the accuracy and clinical utility of SWE imaging for differentiation of malignant and benign hepatic lesions. Methods PubMed, Embase, Web of Science, and the Cochrane Library were systematically reviewed to search for studies published between January 1, 1990, and November 30, 2018. The studies published in English relating to the evaluation the diagnostic accuracy of SWE imaging for distinguishing malignant and benign liver lesions were retrieved and examined for pooled sensitivity, specificity, likelihood ratios, and diagnostic odds ratios, using bivariate random-effects models. The hierarchical summary receiver operating characteristic (HSROC) curve was estimated to assess the SWE imaging accuracy. The clinical utility of SWE imaging for differentiation of malignant liver lesions was evaluated by Fagan plot. Results A total of 15 studies, involving 1894 liver lesions in 1728 patients, were eligible for the meta-analysis. The pooled sensitivity and specificity for identification of malignant liver lesions were 0.82 (95% CI: 0.77–0.86) and 0.82 (95% CI: 0.76–0.87), respectively. The AUC was 0.89 (95% CI: 0.86–0.91). When the pre-test probability was 50%, after SWE imaging measurement over the cut-off value (positive result), the corresponding post-test probability for the presence of malignant liver lesions was 82%; the post-test probability was 18% after negative measurement. Conclusions SWE imaging showed high sensitivity and specificity in differentiating malignant and benign liver lesions and may be promising for noninvasive evaluation of liver lesions.

Abstract
PURPOSE Percutaneous tissue biopsy is a mainstay of diagnostic and interventional radiology, providing a minimally invasive method for diagnosing malignant and benign disease. The purpose of this review was to collect and summarize the best available evidence regarding the risk factors associated with bleeding complications in image-guided liver biopsy. METHODS A literature review was performed, searching Medline, EMBASE, CINAHL, the Cochrane Library, the National Institute for Health and Care Excellence (NICE) and Canadian Agency for Drugs and Technology in Health (CADTH) databases for any studies evaluating bleeding complications in image-guided liver biopsy. A total of 68 articles, published between January 1994 and April 2015, were reviewed in full, with 34 ultimately eligible for inclusion in the review. RESULTS Bleeding of any kind occurred in up to 10.9% of image-guided liver biopsies, with major bleeding episodes ranging from 0.1% to 4.6% and minor bleeding events occurring in up to 10.9% of biopsies. The overall rate of bleeding was, however, found to be less than 2%. Several risk factors (patient, operator, and procedure-related) were identified as potentially indicative of an increased risk of post-biopsy bleeding. Patient-related risk factors included patient age (>50 years or <2 years), inpatient status (8/12 vs. 4/12, P < 0.001), comorbidities and/or concurrent diagnoses and coagulation status (rate of bleeding was 3.3% for international normalized ratio [INR] 1.2-1.5 vs. 7.1% for INR >1.5, P < 0.001). There was no consensus on impact of operator experience (>200 biopsies/year vs. <50/year) on post-biopsy bleeding rate. Procedure-related risk factors included needle size (cutting biopsy vs. fine needle aspiration, P < 0.001) and the presence of a patent track on post-biopsy ultrasound (P < 0.001). Lastly there was no difference found between targeted vs. nontargeted biopsies and number of needle passes. CONCLUSION Reported rate of post-biopsy bleeding ranges between 0% and 10.9%, although the vast majority of studies reported bleeding rates under 2%. Several patient, operator, and procedure-related risk factors are associated with a higher risk of bleeding following liver biopsy.

Abstract
Hepatoblastoma and hepatocellular carcinoma (HCC) are the most common pediatric liver malignancies, with hepatoblastoma occurring more commonly in younger children and HCC occurring more commonly in older children and adolescents. Although surgical resection (including transplant when necessary) and systemic chemotherapy have improved overall survival rate for hepatoblastoma to approximately 80% from 30%, a number of children with this tumor type are not eligible for operative treatment. In contradistinction, pediatric HCC continues to carry a dismal prognosis with an overall 5-year survival rate of 30%. The Paediatric Hepatic International Tumour Trial (PHITT) is an international trial aimed at evaluating both existing and emerging oncologic therapies for primary pediatric liver tumors. Interventional radiology offers a number of minimally invasive procedures that aid in diagnosis and therapy of pediatric liver tumors. For diagnosis, the PHITT biopsy guidelines emphasize and recommend percutaneous image-guided tumor biopsy. Additionally, both percutaneous and endovascular procedures provide therapeutic alternatives that have been, to this point, only minimally utilized in the pediatric population. Specifically, percutaneous ablation offers a number of cytotoxic technologies that can potentially eradicate disease or downstage children with unresectable disease. Percutaneous portal vein embolization is an additional minimally invasive procedure that might be useful to induce remnant liver hypertrophy prior to extended liver resection in the setting of a primary liver tumor. PHITT offers an opportunity to collect data from children treated with these emerging therapeutic options across the world. The purpose of this manuscript is to describe the potential role of minimally invasive percutaneous transhepatic procedures, as well as review the existing data largely stemming from the adult HCC experience.

Abstract
INTRODUCTION Hepatic resection is performed for various benign and malignant liver tumors. Over the last several decades, there have been improvements in the surgical technique and postoperative care of patients undergoing liver surgery. Despite this, liver failure following an extended hepatic resection remains a critical potential postoperative complication. Patients with underlying parenchymal liver diseases are at particular risk of liver failure due to impaired liver regeneration with an associated mortality risk as high as 60 to 90%. In addition, live donor liver transplantation requires a thorough presurgical assessment of the donor liver to minimize the risk of postoperative complications. RESULTS AND CONCLUSION Recently, cross-sectional imaging assessment of diffuse liver diseases has gained momentum due to its ability to provide both anatomical and functional assessments of normal and abnormal tissues. Various imaging techniques are being employed to assess diffuse liver diseases including magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound (US). MRI has the ability to detect abnormal intracellular and molecular processes and tissue architecture. CT has a high spatial resolution, while US provides real-time imaging, is inexpensive, and readily available. We herein review current state-of-the-art techniques to assess the underlying non-tumorous liver. Specifically, we summarize current approaches to evaluating diffuse liver diseases including fatty liver alcoholic or non-alcoholic (NAFLD, AFLD), hepatic fibrosis (HF), and iron deposition (ID) with a focus on advanced imaging techniques for non-invasive assessment along with their implications for patient management. In addition, the role of and techniques to assess hepatic volume in hepatic surgery are discussed.

Abstract
Klatskin's tumors, actually-redefined as perihilar cholangiocarcinoma (phCCA) do represent 50-70% of all CCAs and develop in a context of chronic inflammation and cholestasis of bile ducts. Surgical resection provides the only chance of cure for this disease but is technically challenging because of the complex, intimate and variable relationship between biliary and vascular structures at this location. Five years survival rates range between 25-45% (median 27-58 months) in case of R0 resection and 0-23% (median 12-21 months) in case of R1 resection respectively. It should be noted that the major costs of high radicality are represented by relative high morbidity and mortality rates (i.e., 20-66% and 0-9% respectively). Considering the fact that radical resection may represent the only curative treatment of phCCA, we focused our review on surgical planning and techniques that may improve resectability rates and outcomes for locally advanced phCCA. The surgical treatment of phCCA can be successful when following aspects have been fulfilled: (I) accurate preoperative diagnostic aimed to identify the tumor in all its details (localization and extension) and to study all the risk factors influencing a posthepatectomy liver failure (PHLF): i.e., liver volume, liver function, liver quality, haemodynamics and patient characteristics; (II) High end surgical skills taking in consideration the local extension of the tumor and the vascular invasion which usually require an extended hepatic resection and often a vascular resection; (III) adequate postoperative management aimed to avoid major complications (i.e., PHLF and biliary complications). These are technically challenging operations and must be performed in a high volume centres by hepato-biliary-pancreas (HBP)-surgeons with experience in microsurgical vascular techniques.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is an immune-mediated chronic liver disease that can lead to severe fibrosis and cirrhosis. Transient elastography (TE, FibroScan) can assess the fibrotic stages of chronic liver diseases by liver stiffness measurement (LSM). Studies on the diagnostic accuracy of FibroScan for the detection of fibrosis in AIH patients are still limited. MATERIAL AND METHODS This study enrolled 108 AIH patients who underwent liver biopsies. Using the METAVIR scoring system as the reference, Spearman's rank correlation was performed to explore the relationship between the markers and stages of fibrosis. The area under the receiver operating characteristic curve (AUROC) was used to evaluate the diagnostic accuracy. The optimal LSM cut-off values for predicting the stages of fibrosis were calculated. RESULTS LSM was superior to other non-invasive markers in differentiating the stages of fibrosis in AIH patients. AUROC value of LSM was 0.885 for stage F2, 0.897 for stage F3, and 0.878 for stage F4. The optimal LSM cut-off value was 6.27 kPa for stage F2, 8.18 kPa for F3, and 12.67 kPa for F4. CONCLUSIONS FibroScan is a valuable non-invasive method for the evaluation of liver fibrosis of AIH patients.

Abstract
We developed an optimal noninvasive index comprising routine laboratory parameters for predicting cirrhosis in chronic hepatitis B (CHB) and chronic hepatitis C (CHC) patients. This study included 992 CHB patients and 1,284 CHC patients who received liver biopsy. We developed the new index, named modified Fibrosis-4 (mFIB-4) according to four independent variables of the model: age, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and platelet count. The formula of the mFIB-4 index is 10 × Age(years) × AST(U/L)/Platelet count(109/L) × AST(U/L). For predicting cirrhosis, the bootstrap areas under the receiver operating characteristic curve for platelet count, AST/ALT ratio (AAR), AAR/platelet ratio index (AARPRI), AST/platelet ratio index (APRI), FIB-4, Pohl score, age-platelet (AP) index, Lok index, fibrosis quotient (FibroQ), and mFIB-4 were 0.7680, 0.7400, 0.8070, 0.6090, 0.7690, 0.6990, 0.7850, 0.7960, 0.8110, and 0.8070 in CHB patients, and 0.8170, 0.7210, 0.8400, 0.7310, 0.8310, 0.6730, 0.8220, 0.8440, 0.8570, and 0.8480 in CHC patients, respectively. FibroQ and mFIB-4 exhibited the highest diagnostic performance levels for liver cirrhosis in CHB and CHC despite the inclusion of the international normalised ratio in the formulation of FibroQ. Thus, mFIB-4 is a simple, inexpensive, and readily available method for assessing the liver fibrosis stage of Asian patients with CHB or CHC.

Abstract
BACKGROUND Liver biopsy, which is considered the best method for evaluating hepatic fibrosis, has important adverse events. Therefore, non-invasive tests have been developed to determine the degree of hepatic fibrosis in patients with chronic hepatitis B. AIM To verify the usefulness of a new fibrosis index the globulin/platelet model in patients with chronic hepatitis B and to compare it with other noninvasive tests for predicting significant fibrosis. This study was the second to evaluate the globulin/platelet model in HBV patients. METHODS We retrospectively investigated 228 patients with chronic hepatitis B who performed liver biopsy from 2013 to 2014. The globulin/platelet model, APGA [AST/Platelet/Gamma-glutamyl transpeptidase/Alfa-fetoprotein], FIB4, fibrosis index, cirrhosis discriminate score, and Fibro-quotient were calculated, and the diagnostic accuracies of all of the fibrosis indices were compared between the F0-2 (no-mild fibrosis) and F3-6 (significant fibrosis) groups. RESULTS All of the noninvasive markers were significantly correlated with the stage of liver fibrosis (p < 0,001). To predict significant fibrosis (F ≥ 3), the area under the curve (95% CI) was found to be greatest for APGA (0.83 [0.74-0.86]), followed by FIB-4 (0.75[0.69-0.80]), the globulin/platelet model (0.74 [0.68-0.79]), fibrosis index (0.72 [0.6-0.78], cirrhosis discriminate score (0.71 [0.64-0.76]) and Fibro-quotient (0.62 [0.55-0.7]). The area under the receiver operating characteristic curves of APGA was significantly higher than that of the other noninvasive fibrosis markers (p < 0.05). CONCLUSIONS While the APGA index was found to be the most valuable test for the prediction significant fibrosis in patients with chronic hepatitis B, GP model was the thirth valuable test. Therefore, we recommended that APGA could be used instead of the GP model for prediction liver fibrosis.

Abstract
AIM To perform a comparative analysis of computerized tomographic volumetry and scintigraphic liver volumetry in assessment of remnant liver volume after advanced hepatic resection. MATERIAL AND METHODS Static hepatobiliary scintigraphy and CT volumetry were performed in 45 patients with various liver tumors who underwent advanced hepatectomies (more than three segments). RESULTS There were no any significant differences in volumetric parameters obtained by CT and scintigraphic volumetry. CONCLUSION Scintigraphic volumetry data are similar to those of CT volumetry in evaluation of future remnant liver volume. Scintigraphic volumetry may be used as an alternative in assessment of future remnant liver volume after advanced hepatic resections.

Abstract
Chronic liver disease is a major cause of morbidity and mortality worldwide and usually develops over many years, as a result of chronic inflammation and scarring, resulting in end-stage liver disease and its complications. The progression of disease is characterised by ongoing inflammation and consequent fibrosis, although hepatic steatosis is increasingly being recognised as an important pathological feature of disease, rather than being simply an innocent bystander. However, the current gold standard method of quantifying and staging liver disease, histological analysis by liver biopsy, has several limitations and can have associated morbidity and even mortality. Therefore, there is a clear need for safe and non-invasive assessment modalities to determine hepatic steatosis, inflammation and fibrosis. This review covers key mechanisms and the importance of fibrosis and steatosis in the progression of liver disease. We address non-invasive imaging and blood biomarker assessments that can be used as an alternative to information gained on liver biopsy.

Abstract
OBJECTIVES The aim of the study was to describe and assess the technical success and safety of ultrasound-guided liver biopsy with gelatin sponge pledget tract embolization technique in infants <10 kg across 3 tertiary pediatric hospitals. MATERIALS AND METHODS There were 67 pediatric patients weighing <10 kg (36 boys; 31 girls; average age 202 days; average weight 6 kg, range 1.5-9.9 kg) referred for liver biopsy performed with ultrasound guidance and gelatin sponge pledget tract embolization during a 2-year period. Patient history, procedural records, and clinical follow-up documents were retrospectively reviewed. RESULTS A total of 67 procedures were included. There was 100% technical success rate and all samples obtained provided adequate tissue for histological assessment. Average number of 18 G biopsy passes was 3 (range 1-6). There were no procedure-related deaths. There was 1 complication (1%) in a 5-kg infant who was readmitted 36 hours after biopsy with a fever and fully recovered after antibiotics were administered. Biliary atresia was the most common underlying diagnosis (20%), whereas others included acute rejection (16%) and biliary obstruction (7%). CONCLUSIONS Ultrasound-guided percutaneous liver biopsy with gelatin sponge pledget tract embolization technique in children weighing <10 kg is safe, effective, and use of this technique may lead to a reduction in rates of adverse events reported in other pediatric series.

Abstract
OBJECTIVES Autoimmune hepatitis (AIH) is a relatively rare cause of hepatic dysfunction, which can lead to acute liver failure (ALV) and cirrhosis if not treated. The performance of transient elastography (TE) compared to liver biopsy has been evaluated in many liver diseases. The aim of the present study was to evaluate the performance of TE and other non-invasive markers for liver fiibrosis in patients with biopsy-proven AIH. METHODS Fifty-three patients who were treated at the department of gastroenterology and hepatology of the University Clinic Essen from 2008 to 2013 included in this retrospective study. Laboratory parameters were used to calculate non-invasive markers for liver fiibrosis. Every patient underwent a liver biopsy within 6 months of the liver stiffness measurement. RESULTS Transient elastography score, non-alcoholic fatty liver disease (NAFLD) fiibrosis score, Fiibrosis 4 score (FIB-4), and FibroQ were associated with the stage of fiibrosis, whereas other non-invasive markers of liver fiibrosis (aspartate transaminase (AST) to alanine transaminase (ALT) ratio, and AST to platelet ratio index (APRI)) did not demonstrate a significant correlation. NAFLD fiibrosis score and FibroQ performed slightly better in ROC curve analysis than TE in differentiating mild to moderate from severe fiibrosis (AUC 0.895 and 0.773 vs. 0.739; P < 0.001 and = 0.01, respectively), while TE performed slightly better, but still not adequate, in differentiating mild from all other stages of fiibrosis compared to NAFLD fiibrosis score and FibroQ (AUC 0.779 vs. 0.752 and 0.684; P = 0.051 and 0.009). CONCLUSIONS Transient elastography, NAFLD fiibrosis score, and FibroQ are valuable non-invasive markers for the evaluation of liver fiibrosis in autoimmune hepatitis but they cannot replace liver biopsy, especially in differentiating mild from more advanced stages of fiibrosis.

Abstract
Hepatic fibrosis is a common pathway leading to liver cirrhosis, which is the end result of any injury to the liver. Accurate assessment of the degree of fibrosis is important clinically, especially when treatments aimed at reversing fibrosis are being evolved. Despite the fact that liver biopsy (LB) has been considered the "gold standard" of assessment of hepatic fibrosis, LB is not favored by patients or physicians owing to its invasiveness, limitations, sampling errors, etc. Therefore, many alternative approaches to assess liver fibrosis are gaining more popularity and have assumed great importance, and many data on such approaches are being generated. The Asian Pacific Association for the Study of the Liver (APASL) set up a working party on liver fibrosis in 2007, with a mandate to develop consensus guidelines on various aspects of liver fibrosis relevant to disease patterns and clinical practice in the Asia-Pacific region. The first consensus guidelines of the APASL recommendations on hepatic fibrosis were published in 2009. Due to advances in the field, we present herein the APASL 2016 updated version on invasive and non-invasive assessment of hepatic fibrosis. The process for the development of these consensus guidelines involved review of all available published literature by a core group of experts who subsequently proposed consensus statements followed by discussion of the contentious issues and unanimous approval of the consensus statements. The Oxford System of the evidence-based approach was adopted for developing the consensus statements using the level of evidence from one (highest) to five (lowest) and grade of recommendation from A (strongest) to D (weakest). The topics covered in the guidelines include invasive methods (LB and hepatic venous pressure gradient measurements), blood tests, conventional radiological methods, elastography techniques and cost-effectiveness of hepatic fibrosis assessment methods, in addition to fibrosis assessment in special and rare situations.

Abstract
AIMS French clinical practice guidelines on the use of liver biopsy (LB) published in 2002 focused on ultrasound guidance (USG) and ambulatory LB. The aims of this study were as follows: (i) to evaluate the number and indications for LB for chronic liver diseases and (ii) to evaluate LB modalities according to French clinical practice guidelines. Data recorded included the number and indications for LB, procedures, use of USG, and complications. RESULTS A total of 131 centers participated: 8741 LB were performed versus 12 000 in 1997; ambulatory LB was performed in 48.6% of cases (vs. 27% in 1997; P<0.001). USG during LB was used in 89.7% of the centers, among which 42 (31.8%) used real-time USG (vs. 56 and 22%, respectively, in 1997; P<0.01). The main indications for LB were chronic hepatitis C in 24.6% of cases (vs. 54.1% in 1997; P<0.001), and viral B or B-delta in 15.0% (vs. 5.8%; P<0.001). Severe complications were less frequent at centers with systematical USG during LB than at those without such guidance (P<0.01). CONCLUSION In this large nationwide study, major trends were as follows: (i) a marked decrease in LB number, related to a decrease in LB for chronic viral hepatitis C; (ii) increased use of USG; and (iii) an increase in the number of ambulatory LB. Severe complications decreased significantly at centers in which USG was systematically applied.

Abstract
BACKGROUND AND AIM Individuals with type 2 diabetes are at heightened risk for nonalcoholic fatty liver disease, which gives rise to nonalcoholic steatohepatitis (NASH) and cirrhosis. Yet, current guidelines do not recommend screening for NASH among these high-risk patients. Using a simulation model, we assessed the effectiveness and cost-effectiveness of screening diabetic patients for NASH. METHODS A Markov model was constructed to compare two management strategies for 50-year-olds with diabetes. In the No Screening strategy, patients do not undergo screening, although NASH may be diagnosed incidentally over their lifetime. In the NASH Screening strategy, all patients receive a one-time screening ultrasound. Individuals with fatty infiltration on ultrasound then have a liver biopsy, and those found to have NASH receive medical therapy, which decreases progression to cirrhosis. Endpoints evaluated included quality-adjusted life years (QALYs) gained, costs, and incremental cost-effectiveness ratios (ICERs). RESULTS Screening for NASH decreased the number of individuals who developed cirrhosis by 12.9 % and resulted in an 11.9 % decrease in liver-related deaths. However, screening resulted in 0.02 fewer QALYs, due to the disutility associated with treatment, and was therefore dominated by the No Screening strategy. When the model excluded this quality-of-life decrement, screening became cost-effective, at an ICER of $42,134 per QALY. CONCLUSIONS Screening for NASH may improve liver-related outcomes, but is not cost-effective at present, due to side effects of therapy. As better tolerated treatments for NASH become available, even with modest efficacy, screening for NASH will become cost-effective.

Abstract
UNLABELLED Primary sclerosing cholangitis (PSC) is a rare, but serious, cholestatic disease for which, to date, no effective therapy exists to halt disease progression toward end-stage liver disease. Clinical trial design to study drugs that improve prognosis is hampered by the relatively low event rate of clinically relevant endpoints. To overcome this shortcoming, there is an urgent need to identify appropriate surrogate endpoints. At present, there are no established surrogate endpoints. This article provides a critical review and describes the results of a consensus process initiated by the International PSC Study Group to delineate appropriate candidate surrogate endpoints at present for clinical trials in this frequently dismal disease. The consensus process resulted in a shortlist of five candidates as surrogate endpoints for measuring disease progression: alkaline phosphatase (ALP); transient elastography (TE); histology; combination of ALP+histology; and bilirubin. Of these, histology, ALP, and TE came out as the most promising. However, the expert panel concluded that no biomarker currently exceeds level 3 validation. Combining multiple endpoints is advisable. CONCLUSION At present, there are insufficient data to support level 2 validation for any surrogate endpoint in PSC. Concerted efforts by all stakeholders are highly needed. Novel, promising noninvasive biomarkers are under study and should be incorporated as exploratory endpoints in clinical trials.

Abstract
The liver biopsy has been regarded as the reference standard method of monitoring hepatic fibrosis in psoriasis patients treated with methotrexate. It has also been subject to concerns over sampling error, internal and external variability, and potential for morbidity and mortality. During the past two decades, two imaging techniques, magnetic resonance elastography and transient elastography, have been developed and approved by the US Food and Drug Administration (FDA) for the assessment of hepatic fibrosis. Although high-quality, psoriasis-specific data are lacking, both methods have been shown to have outstanding efficacy in the detection of hepatic fibrosis, particularly the more advanced stages which may warrant the choice of a therapeutic alternative to methotrexate. Dermatologists should be aware of the availability of these tests and understand their limitations. Prospective studies in psoriasis and methotrexate management using these techniques are needed.

Abstract
OBJECTIVE To determine the incidence of major adverse events related to a large volume of image-guided liver biopsies performed at our institution over a 12-year period and to identify risk factors for major bleeding events. PATIENTS AND METHODS A retrospective analysis of an internally maintained biopsy registry was performed. The analysis revealed that 6613 image-guided liver biopsies were performed in 5987 adult patients between December 7, 2001, and December 31, 2013. Liver biopsies were performed using real-time ultrasound guidance and a spring-loaded biopsy device, with rare exceptions. Adverse events considered major and included in this study were hematoma, infection, pneumothorax, hemothorax, and death. Using data from the biopsy registry, we evaluated statistically significant risk factors (P<.05) for hematoma related to image-guided liver biopsy, including coagulation status, biopsy technique, and medications. RESULTS A total of 49 acute and delayed major adverse events (0.7%) occurred after 6613 liver biopsy events. The incidence of hematoma requiring transfusion and/or angiographic intervention was 0.5% (34 of 6613). The incidence of infection was 0.1% (8 of 6613), and that of hemothorax was 0.06% (4 of 6613). No patient (0%) incurred a pneumothorax after biopsy. Three patients (0.05%) died within 30 days of liver biopsy, 1 being directly related to biopsy. Thirty-eight of 46 major adverse events (83%) presented acutely (within 24 hours). More than 2 biopsy passes, platelets 50,000/μL or less, and female sex were statistically significant risk factors for postbiopsy hemorrhage. CONCLUSION Image-guided liver biopsy performed by subspecialized interventionalists at a tertiary medical center is safe when the platelet count is greater than 50,000/μL. With appreciation of specific risk factors, safety outcomes of this procedure can be optimized in both general and specialized centers.

Abstract
Purpose To evaluate the diagnostic performance of magnetic resonance (MR) elastography in staging liver fibrosis in patients with chronic hepatitis B (CHB) and other etiologic causes. Materials and Methods This retrospective study was institutional review board-approved and the requirement for informed consent was waived. Before surgery, MR elastographic imaging was performed in 352 patients with chronic liver diseases (281 patients with CHB, 71 patients without CHB) and hepatocellular carcinomas and 64 living liver donor candidates. Liver stiffness (LS) values were measured on quantitative shear-stiffness maps of MR elastography, and the diagnostic performance of MR elastography in staging liver fibrosis was evaluated by using receiver operating characteristic curve analysis and the Obuchowski measure with the histopathologic analysis of liver fibrosis in the CHB group and in the group composed of other etiologic causes. In 120 patients (97 with CHB, 23 without CHB) and 51 donors, diagnostic performance of MR elastography was validated. Results Areas under the curve of LS values for the diagnosis of significant fibrosis (≥stage F2), severe fibrosis (≥stage F3), and cirrhosis (stage F4) in the CHB group were 0.972 (95% confidence interval: 0.948, 0.987), 0.946 (95% confidence interval: 0.916, 0.968), and 0.920 (95% confidence interval: 0.885, 0.947), respectively. Obuchowski measures were similarly high in the CHB group and in the group composed of other etiologic causes (0.970 vs 0.977). However, the estimated cutoff value for stage F4 in the group with CHB was substantially lower than in the participants with other etiologic causes: 3.67 kPa versus 4.65 kPa. In the validation study for stage F1 or greater, stage F2 or greater, stage F3 or greater, and stage F4, the Youden indexes were 0.807, 0.842, 0.806, and 0.639, respectively, in the group with CHB, and 0.783, 0.900, 1.000, and 0.917, respectively, in the group without CHB. Conclusion The diagnostic performance of MR elastography in liver fibrosis staging was similarly high in the groups with and without CHB, but the cutoff LS values for diagnosing liver cirrhosis differed between the groups with and without CHB.

Abstract
PURPOSE Elastography is a non-invasive method to quantify fibrosis based on tissue mechanical properties. We performed a meta-analysis to assess the diagnostic accuracy of two such techniques: Acoustic Radiation Force Impulse Imaging (ARFI) or Magnetic Resonance Elastography (MRE) for staging hepatic fibrosis. MATERIALS AND METHODS Literature databases were searched until June 2013. Inclusion criteria were evaluation of MRE or ARFI, liver biopsy, and reported sensitivity and specificity. A random effects model was used to combine sensitivity and specificity, from which positive (LR+) and negative (LR-) likelihood ratios, diagnostic odds ratios, and area under receiver operating characteristics curve (AUROC) were derived. Differences between MRE and ARFI were compared with t tests (P < 0.05 considered significant). RESULTS Eleven MRE studies including 982 patients and fifteen ARFI studies including 2,128 patients were selected. AUROC for MRE staging fibrosis were 0.94, 0.97, 0.96, and 0.97 for F1-F4, respectively, whereas AUROC for ARFI staging were 0.82, 0.85, 0.94, and 0.94 for F1-F4, respectively. Significance was found in AUROC between MRE and ARFI for the diagnosis of stage 1 and 2 fibrosis. CONCLUSION MRE is more accurate than ARFI with a higher combination of sensitivity, specificity, LR, and AUROC particularly in diagnosing early stages of hepatic fibrosis.

Abstract
OBJECTIVE Liver biopsy is still the gold standard for the determination of liver fibrosis and necroinflammatory activity. It is an invasive method and may lead to severe complications. The aim of this study was to determine the evaluation of percutaneous liver biopsy complications in patients with chronic viral hepatitis. MATERIALS AND METHODS 1165 patients, who were followed with the diagnosis of chronic viral hepatitis and who were applied percutaneous liver biopsy between January 2000 and February 2013 at the out-patient clinic of Infectious Diseases and Clinical Microbiology, were included in the study. RESULTS Of 1165 patients who underwent liver biopsy, 196 (86 male, 110 female) were diagnosed with chronic hepatitis C, 969 (559 male, 410 female) were diagnosed with chronic hepatitis B. The mean age was 43.3 and 55.4% were male. 11% of the patients were diagnosed with chronic renal failure and underwent haemodialysis. Minor complication rate was about 20% (severe pain required usage of analgesic drugs in 19.8%, abdominal pain in 22.6%) whereas major complication rate was 1.15% (pneumothorax in 0.17%, heamobilia in 0.08%, hematoma in 0.9%). We did not observe severe complications such as fever, abscess, anaphylaxis, bacteraemia, organ perforations, sepsis or death. CONCLUSION Despite being an invasive procedure, percutaneous liver biopsy can be considered a safe method because of the low rates of severe complications observed in our patients.

Abstract
BACKGROUND The influence of ethnicity on pain complicating ultrasound-guided percutaneous liver biopsy (US-guided PLB) and its clinical impact has not been reported to date. METHODS Consecutive adults from a multiethnic background, undergoing an US-guided PLB, were independently assessed for pain up to 6 h after the procedure. Clinical and demographic parameters were analysed to determine independent predictors of significant pain after PLB. Willingness to undergo a repeat procedure was assessed 1 week after PLB. RESULTS Data from 203 patients (median age 50 years; 43.9% female; ethnicity: Malay 41.5%, Chinese 40%, Indian 18%; median BMI 27.7 kg/m; median waist circumference 92.0 cm) were analysed. Pain after US-guided PLB was experienced in 133 (61.1%) patients, with severity grades as follows: none, n=81 (39.9%); mild, n=56 (27.6%); moderate, n=51 (25.1%); and severe, n=15 (7.4%). Analgesia requirements correlated well with severity of pain. Independent predictors of significant pain after PLB (moderate and severe categories) in patients included age less than 50 years [odds ratio (OR) 3.0], female sex (OR 3.7), Indian ethnicity (OR 2.9) and Malay ethnicity (OR 2.7), but not number of needle passes, BMI and educational levels. Patients who experienced moderate/severe pain were less willing to undergo a repeat PLB compared with those who experienced mild/no pain (60.9 vs. 82.8%, P=0.001). CONCLUSION Ethnicity has an important role in the development of pain after US-guided PLB. This has a significant impact on willingness to repeat the procedure.

Abstract
Liver biopsy (LB) is still the criterion standard procedure for obtaining liver tissue for histopathological examination and a valuable tool in the diagnosis, prognosis, and management of many parenchymal liver diseases. The aim of this position paper is to summarise the present practice of paediatric LB and make recommendations about its performance. Although histological evaluation of the liver is important in assessing prognosis and exploring treatment, noninvasive techniques (ie, imaging, laboratory markers) may replace use of liver histology. The indications for LB are changing as present knowledge of aetiologies, pathomechanism, and therapeutic options in paediatric liver disease is evolving. Adult and paediatric literature was reviewed to assess the existing clinical practice of LB with focus on the technique, indications, risk of complications, and contraindications in paediatrics. This position paper presents types of LB, indications, complications, contraindications, and an essential checklist for paediatric LB.

Abstract
In order to achieve microscopic radical resection margins and thus better survival, surgical treatment of hepatic tumors has become more aggressive in the last decades, resulting in an increased rate of complex and extended liver resections. Postoperative outcomes mainly depend on the size and quality of the future remnant liver (FRL). Liver resection, when performed in the absence of sufficient FRL, inevitably leads to postresection liver failure. The current gold standard in the preoperative assessment of the FRL is computed tomography volumetry. In addition to the volume of the liver remnant after resection, postoperative function of the liver remnant is directly related to the quality of liver parenchyma. The latter is mainly influenced by underlying diseases such as cirrhosis and steatosis, which are often inaccurately defined until microscopic examination after the resection. Postresection liver failure remains a point of major concern that calls for accurate methods of preoperative FRL assessment. A wide spectrum of tests has become available in the past years, attesting to the fact that the ideal methodology has yet to be defined. The aim of this review is to discuss the current modalities available and new perspectives in the assessment of FRL in patients scheduled for major liver resection.

Abstract
BACKGROUND Percutaneous liver biopsy (PLB) is the standard procedure to obtain histological samples essential for the management of various liver diseases. While safe, many hepatologists no longer perform their own PLBs; the reasons for this practice shift are unknown. OBJECTIVE To describe the attitudes, practice patterns and barriers to PLB among hepatologists in Canada. METHODS A survey was distributed to all hepatologists in Canada. RESULTS Thirty-two of 40 (80%) hepatologists completed the survey; the majority of respondents were male (72%) and had been in practice for >5 years in an academic setting. Fifty-six per cent of hepatologists referred all PLBs to radiology, and only 19% of hepatologists reported performing their own PLBs most or all of the time. There were no sex differences nor were there differences based on years in practice. Fifty per cent of respondents who performed PLB routinely used ultrasound, and PLBs are performed in equal frequency in an ambulatory procedure area (50%) versus the endoscopy suite (36%). For almost one-half of hepatologists (47%), their performance of PLBs decreased in the past five years. The majority of respondents at an academic centre (75%) reported access to FibroScan (Echosens, France), and most estimated a resultant 25% to 50% reduction in the need for PLBs. Lack of resources, patient preference and suboptimal reimbursement were the most common reasons cited for not performing PLBs. CONCLUSION Most hepatologists in Canada do not perform PLBs to the extent that they did in the past, but refer to radiology. The reasons for this shift in practice include lack of resources, improved perception of safety and patient preference. Where available, FibroScan resulted in a perceived 25% to 50% reduction in required liver biopsies.

Abstract
OBJECTIVE The aim of the present study was to assess whether the complication rate after ultrasound-guided percutaneous liver biopsies in children is affected by how frequently the procedure is performed by the operator. METHODS Medical charts and ultrasound descriptions of 311 ultrasound-guided percutaneous liver biopsy procedures performed by 18 radiologists at a single center from 2000 to 2011 were reviewed. Postbiopsy ultrasound the following day was performed after 97% of the procedures. RESULTS There were no differences in the procedure-associated rate of major bleeding incidents (2.2% vs 0.8%, P = 0.38), minor bleeding incidents (15.2% vs 10.2%, P = 0.31), or abdominal pain (13.0% vs 10.6%, P = 0.61) among operators who performed ≤10 procedures and those who performed >10 procedures during the study period. A higher rate of minor bleeding incidents were recorded after liver biopsy when operators had performed <10 biopsies compared with operators who had performed >20 pediatric liver biopsies during the study period (odds ratio 3.4 [1.3-9.1], P = 0.02). No association between the number of biopsies performed by the operator during the 2 years preceding the date of the biopsy and complications was found. CONCLUSIONS Major complications are infrequent after pediatric liver biopsies and no relation between operator experience and major complications was found. We found a significant, but minor, effect of operator procedure frequency on the rate of minor bleeding incidents after ultrasound-guided pediatric liver biopsies.

Abstract
BACKGROUND Liver biopsy is the "gold standard" for evaluating liver disorders, but controversies over the potential risk of complications and patient discomfort still exist. Using a 21G fine needle, we developed a new biopsy procedure, fine needle aspirating and cutting (FNAC). Our procedure obtains enough tissue for pathological examination and meanwhile, reduces the risk of biopsy complications. The present study was to determine the safety and efficiency of 21G FNAC compared with 18G Tru-cut core needle (TCN) in liver tumor biopsies. METHODS Ninety-four patients with unresectable malignant tumors were included in this study. Patients were divided into 2 groups: 18G TCN and 21G FNAC. The total positive rate (TPR) and safety of both groups were compared. RESULTS TPR was not different between the two groups. Liver puncture track subcapsular hemorrhage and arteriovenous shunt were reported with 18G TCN but not with 21G FNAC. The incidence of pain caused by biopsy was higher for the 18G TCN group compared to the 21G FNAC group (P<0.05). About 82.6% of the patients in the 18G TCN group had a sample length >0.5 cm, but 52.1% in the 21G FNAC group (P<0.05). More than 50% of patients in both groups had sufficient tissue for immunohistochemical examination. CONCLUSIONS TPR is not different between the 21G FNAC and 18G TCN biopsy procedures, but the safety of 21G FNAC is superior to that of 18G TCN. Tissues obtained by either of these two procedures are sufficient for a pathological diagnosis.
