Abstract
OBJECTIVE To evaluate the feasibility and efficacy of transjugular liver biopsy in patients with contraindicated percutaneous biopsy. MATERIALS AND METHODS Between June 2005 and April 2010, 97 patients who were admitted for transjugular liver biopsy were enrolled in this retrospective study. All liver biopsies were obtained using an 18 gauge Quick-Core liver biopsy set through the right hepatic vein via the internal jugular vein. Clinical indication, histopathological diagnosis, and complications were noted. RESULTS Primary technical success was achieved in 93 (95.8%) patients. Hepatic veins could not be catheterized and opacified in two patients and in the remaining two patients the veins could be opacified and catheterized but we were not able to pass the biopsy needle into the hepatic vein because of the acute angle between the inferior vena cava and hepatic veins. At least two specimens were obtained from each patient. The most frequent histopathological diagnosis was cirrhosis. A subcutaneous hematoma around the puncture side was encountered in one patient. CONCLUSION Transjugular liver biopsy is a feasible and effective alternative in patients with contraindication for percutaneous biopsy.

Abstract
UNLABELLED Studies of the prognostic value of Ishak fibrosis stage are lacking. We used multi-year follow-up of the Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis (HALT-C) Trial to determine whether individual Ishak fibrosis stages predicted clinical outcomes in patients with chronic hepatitis C. Baseline liver biopsy specimens from 1050 patients with compensated chronic hepatitis C who had failed combination peginterferon and ribavirin were reviewed by a panel of expert hepatopathologists. Fibrosis was staged with the Ishak scale (ranging from 0 = no fibrosis to 6 = cirrhosis). Biopsy fragmentation and length as well as number of portal tracts were recorded. We compared rates of prespecified clinical outcomes of hepatic decompensation and hepatocellular carcinoma across individual Ishak fibrosis stages. Of 1050 biopsy specimens, 25% were fragmented, 63% longer than 1.5 cm, 69% larger than 10 mm(2), and 75% had 10 or more portal tracts. Baseline laboratory markers of liver disease severity were worse and the frequency of esophageal varices higher with increasing Ishak stage (P < 0.0001). The 6-year cumulative incidence of first clinical outcome was 5.6% for stage 2, 16.1% for stage 3, 19.3% for stage 4, 37.8% for stage 5, and 49.3% for stage 6. Among nonfragmented biopsy specimens, the predictive ability of Ishak staging was enhanced; however, no association was observed between Ishak stage and outcomes for fragmented biopsy specimens because of high rates of outcomes for patients with noncirrhotic stages. Similar results were observed with liver transplantation or liver-related death as the outcome. CONCLUSION Ishak fibrosis stage predicts clinical outcomes, need for liver transplantation, and liver-related death in patients with chronic hepatitis C. Patients with fragmented biopsy specimens with low Ishak stage may be understaged histologically.

Abstract
OBJECTIVES Liver biopsy is a valuable clinical tool, but for the interpretation to be meaningful a certain core size should be obtained. This study examines the changes the liver biopsy core undergoes during processing steps. METHODS A total of 61 consecutive percutaneous liver biopsies were obtained between November 2004 and April 2005. The needle type utilized was the 16-gauge automatic tru-cut. A measurement was made while each liver biopsy core specimen resided in the cartridge, then a measurement was made with the core placed on the tray, and a final measurement was made after the pathologist received the formalin-fixed specimen. RESULTS The mean size of the biopsy core in the cartridge measured 15 +/- 2 mm, compared to a mean size on the tray of 19.6 +/- 3.5 mm, and a mean size after fixation of 18.3 mm. All mean sizes were statistically different from one another. The compressive effect of the cartridge was 23%. The shrinkage effect of formalin fixation was 7%. CONCLUSIONS The liver biopsy core size changes significantly through the processing steps. It is imperative that the operator is aware of these changes so that appropriate decisions are made. As an example, if the operator underestimates the core size when measured in the cartridge, a second pass may be completed when in fact adequate tissue had been obtained on the first pass.

Abstract
Transjugular liver biopsy (TJLB) is considered an inferior biopsy, used when percutaneous liver biopsy (PLB) is contraindicated. According to recent literature, specimens with 6 complete portal tracts (CPTs) are needed for histological diagnosis of chronic liver disease but 11 CPTs to reliably stage and grade. Mean CPT number in PLB series is 7.5; more passes increase complications. Sixty-four series reporting 7649 TJLBs were evaluated for quality of specimen and safety. Major indications were coagulation disorders and/or ascites. Success rate was 96.8%. Fragmentation rate was 34.3%, not correlating with length or diagnostic adequacy. With a mean of 2.7 passes, mean CPT number was 6.8. Histological diagnosis was achieved in 96.1% of TJLBs, correlating with length (p=0.007) and CPT number (p=0.04). Tru-Cut specimens had a mean CPT number of 7.5 and, compared to Menghini specimens, were longer (p<0.008), less fragmented (p<0.001) and more diagnostic (p<0.001). Thinner needles (>16-G) provided significantly longer and less fragmented specimens. Minor and major complication rates were 6.5% and 0.56%, respectively, and increased in children, but not with additional passes. In adults, mortality was 0.09% (haemorrhage 0.06%; ventricular arrhythmia 0.03%). TJLB is safe, providing specimens qualitatively comparable to PLB, and may improve further using > or = 18-G Tru-Cut needle and >3 passes.

Abstract
AIM: To evaluate sample adequacy, safety, and needle passes of a new biopsy needle device compared to the Quick-Core biopsy needle for transjugular liver biopsy in patients affected by liver disease.
METHODS: Thirty consecutive liver-disease patients who had major coagulation abnormalities and/or relevant ascites underwent transjugular liver biopsy using either a new needle device (18 patients) or the Quick-Core biopsy needle (12 patients). The length of the specimens was measured before fixation. A pathologist reviewed the histological slides for sample adequacy and pathologic diagnoses. The two methods’ specimen adequacy and complication rates were assessed.
RESULTS: Liver biopsies were technically successful in all 30 (100%) patients, with diagnostic histological core specimens obtained in 30 of 30 (100%) patients, for an overall success rate of 100%. With the new device, 18 specimens were obtained, with an average of 1.1 passes per patient. Using the Quick-Core biopsy needle, 12 specimens were obtained, with an average of 1.8 passes per patient. Specimen length was significantly longer with the new needle device than with the Quick-Core biopsy needle (P < 0.05). The biopsy tissue was not fragmented in any of the specimens with the new aspiration needle device, but tissue was fragmented in 3 of 12 (25.0%) specimens obtained using the Quick-Core biopsy needle. Complications included cardiac arrhythmia in 3 (10.0%) patients, and transient abdominal pain in 4 (13.3%) patients. There were no cases of subcapsular hematoma, hemoperitoneum, or sepsis, and there was no death secondary to the procedure. In particular, no early or delayed major procedure-related complications were observed in any patient.
CONCLUSION: Transjugular liver biopsy is a safe and effective procedure, and there was significant difference in the adequacy of the specimens obtained using the new needle device compared to the Quick-Core biopsy needle. Using the new biopsy needle device, the specimens showed no tissue fragmentation and no increment in major procedure-related complications was observed.

Abstract
Characteristics for an optimal liver biopsy specimen were recently defined as 20 to 25 mm long and/or containing more than 11 complete portal tracts (CPTs). A systematic review of percutaneous liver biopsy (PLB) and transjugular liver biopsy (TJLB) series yielded only 32 PLB studies in which these characteristics were evaluated: mean +/- SD length, 17.7 +/- 5.8 mm and number of CPTs, 7.5 +/- 3.4; and 15 TJLB studies: mean +/- SD length, 13.5 +/- 4.5 mm and number of CPTs, 6.8 +/- 2.3. Studies of sampling heterogeneity and intraobserver and interobserver variability also used inadequate specimens by present standards. Only 11 (5.3%) of 207 therapeutic studies for chronic hepatitis B and C documented length and/or number of CPTs. Of the current 12 studies evaluating noninvasive fibrosis tests, only 8 documented length or number of CPTs, and only 1 documented length and number of CPTs. New studies are needed based on adequate liver biopsy samples to provide reliable estimation of grading and staging in chronic liver disease.

Abstract
PURPOSE To assess the efficacy and safety of transjugular liver biopsy (TJLB) in patients with end-stage renal disease (ESRD) who are undergoing hemodialysis treatment. MATERIALS AND METHODS Forty-six consecutive patients with liver disease who were undergoing hemodialysis were included in this study. An 18-gauge Tru-cut transjugular needle with a 20-mm throw was used to obtain liver tissue. All procedures were performed under fluoroscopic guidance. A single pathologist reviewed the biopsy specimens and assessed the size of fragments, number of portal tracts, and adequacy of the specimens for histologic diagnosis. All complications were recorded. The results were compared with the outcomes of percutaneous liver biopsy carried out at our institution in 32 patients with ESRD. RESULTS TJLB and percutaneous biopsy techniques yielded adequate specimens for histologic diagnosis in all patients. The mean length of the largest fragments of tissue obtained via the transjugular and percutaneous routes were 16 mm +/- 4 and 14 mm +/- 3, respectively (P = NS). There were no major complications among patients who underwent TJLB. Percutaneous liver biopsy was complicated by hemorrhage in four of 32 patients (12%), three of whom required blood transfusion. CONCLUSION TJLB is an effective and safe technique to obtain liver tissue in patients with ESRD and is associated with a lower complication rate than percutaneous liver biopsy.

Abstract
The prevalence of chronic hepatitis C virus (HCV) infection among patients with severe congenital bleeding disorders is as high as 98%. Advances in HCV treatment currently result in sustained virological response rates of > or =50%. Recent recommendations have reaffirmed that liver biopsy, which provides a direct histological assessment of liver inflammation and fibrosis, is still important for accurate diagnosis and therapeutic decision making. Percutaneous liver biopsy is a simple, standardized procedure that can be performed rapidly and relatively inexpensively, and has been safely performed in patients with congenital coagulopathies. However, the safety and efficacy of the transjugular approach (transjugular liver biopsy, TJLB), recommended for patients with acquired coagulopathies, has only been minimally studied in the congenital bleeding diathesis population. We now report our institutional experience with TJLB in 13 such adult patients (mean age 33 years) with severe/mild haemophilia A/B (10); von Willebrand disease (1); factor V deficiency (1) and factor XIII deficiency (1). Data were collected by retrospective chart review and the TJLB was performed according to institutional protocol as described. Haemostasis prophylaxis was given for 1-5 days. Patients were hospitalized for < or =48 h and all tolerated the procedure without bleeding. Three patients experienced self-limited abdominal discomfort; one episode was accompanied by transient transaminaemia. Diagnostic specimens were obtained from all patients and were instrumental in the therapeutic decision-making process. We suggest that with a co-ordinated multidisciplinary approach to care, TJLB is a safe, effective and potentially cost-effective alternative to the percutaneous approach in the congenital bleeding disorders population.

Abstract
BACKGROUND: Transjugular liver biopsy is an alternative procedure for patients who present contraindications to standard percutaneous procedure. AIM: To compare the rate of histological diagnosis obtained on transjugular liver biopsy with an automated trucut needle and with a modified Ross needle. PATIENTS / METHOD: Eighty-five patients with suspicion of chronic liver diseases and presenting contraindications for percutaneous liver biopsy (coagulopathy, massive ascites, morbid obesity, or chronic renal problems) were submitted to 89 transjugular liver biopsies between March 1994 and April 2001 at ''Hospital São José, Irmandade da Santa Casa de Misercórdia'', Porto Alegre, RS, Brazil. Thirty-five patients underwent 36 biopsies with an automated trucut needle, and 50 patients underwent 53 biopsies with a modified Ross needle. RESULTS: Histological diagnosis was reached in 32/35 subjects submitted to transjugular liver biopsy with the trucut needle (91%) and in 35/50 (70%) submitted to biopsy with the modified Ross needle. Specimens obtained with the trucut needle were significantly larger and less fragmented than those obtained with the Ross needle. CONCLUSION: Transjugular liver biopsy with the automated trucut needle allowed a higher rate of histological diagnosis when compared to the modified Ross needle in patients with suspicion of chronic liver diseases.

Abstract
Although transjugular liver biopsies are frequently performed in patients with impaired blood coagulation, their impact on effecting changes in clinical management has not been assessed. We reviewed our experience with 43 consecutive transjugular liver biopsies performed over 3 years (1998-2000) at Westmead Hospital, Sydney, Australia. The technical success, procedural complication rates and subsequent management of these patients were ascertained from the medical case records. Forty-two (28 men) patients were studied. The indications for liver biopsy were as follows: assessment of hepatitis/cirrhosis status (n = 21), evaluation of liver dysfunction following bone marrow transplantation (n = 19) and miscellaneous (n = 2). All liver biopsies were performed with a Cook 20-G transjugular cutting needle device. Adequate histological samples were obtained in 42 (98%) of the 43 biopsies performed. The pre-biopsy diagnoses were confirmed by histology in 28 cases (65%). A change in clinical diagnosis was observed in 12 (28%) patients, and there were changes to subsequent management in all 12 patients. Four patients developed procedural complications, including small neck haematomas in two patients and a self-limiting biliary fistula in one. The only major complication was an extracapsular bleed from a hepatic laceration. This patient required emergency surgery but recovered. Transjugular liver biopsies can be effectively and safely performed in high-risk patients with impaired coagulation. They aid accurate histological appraisal of liver dysfunction in these patients and influence clinical decision-making.

Abstract
OBJECTIVE The aim of our study was to evaluate the safety and efficacy of transjugular biopsy of the liver in a large population of patients using an 18-gauge automated core biopsy needle. MATERIALS AND METHODS A total of 371 patients underwent 410 attempted transjugular biopsies of the liver during an 80-month period. Data collected included the retrospective review of patients' computerized medical records, clinical charts, and nursing documents. Patient demographic data, indications for liver biopsy, laboratory findings of coagulation values, procedural data including number of needle passes performed, and histologic description of the specimens were noted. Indications varied and included traditional contraindications to the percutaneous approach such as coagulopathy (53%) and ascites (29%). In one patient, the hepatic veins could not be catheterized because of angulation with the inferior vena cava, and in one patient, biopsy was performed using the femoral route because of occlusion of the jugular vein. All patients were followed up for a minimum of 24 hr after the procedure to determine complications. RESULTS The mean number of needle passes per procedure was 3.4 (range, 0-18). Hepatic tissue was obtained in 409 procedures via the venous route (408 transjugular and one transfemoral), and a tissue diagnosis was achieved in 403 (98%). The six tissue samples were nondiagnostic because they were too small (n = 3) or too fragmented (n = 1) or because they did not contain hepatic tissue (n = 2). Ten complications (2.4%) occurred, including three intraperitoneal hemorrhages that resulted in one death. CONCLUSION Transjugular biopsy of the liver using an automatic core biopsy needle is safe and produces adequate tissue specimens in a high percentage of patients.

Abstract
Hepatitis C virus (HCV) infection is present in 2-50% of renal transplant recipients and patients receiving hemodialysis. Renal transplantation confers an overall survival benefit in HCV positive (HCV+) hemodialysis patients, with similar 5-year patient and graft survival to those without HCV infection. However, longer-term studies have reported increased liver-related mortality in HCV-infected recipients. Unfortunately, attempts to eradicate HCV infection before transplant have been disappointing. Interferon is poorly tolerated in-patients with end-stage renal disease and ribavirin is contraindicated because reduced renal clearance results in severe hemolysis. Antiviral therapy following renal transplantation is also poorly tolerated, because of interferon-induced rejection and graft loss. Although the prevalence of hepatitis B virus (HBV) infection has declined in hemodialysis patients and renal transplant recipients since the introduction of routine vaccination and other infection control measures, it remains high within countries with endemic HBV infection (especially Asia-Pacific and Africa). Renal transplantation is associated with reduced survival in HBsAg+ hemodialysis patients. Unlike interferon, lamivudine is a safe and effective antiviral HBV treatment both before and after renal transplantation. Lamivudine therapy commenced at transplantation should prevent early posttransplant reactivation and subsequent progression to cirrhosis and late liver failure. This preemptive therapy should also eradicate early liver failure from fibrosing cholestatic hepatitis. Because cessation of treatment may lead to severe lamivudine-withdrawal hepatitis, most patients require long-term therapy. The development of lamivudine-resistance will be accelerated by immunosuppression and may result in severe hepatitis flares with decompensation. Regular monitoring with liver function tests and HBV DNA measurements should enable early detection and rescue with adefovir. Chronic HCV and HBV infections are important causes of morbidity and mortality in renal transplant recipients. The best predictor for liver mortality is advanced liver disease at the time of transplant, and liver biopsy should be considered in all potential HBsAg+ or HCV+ renal transplant candidates without clinical or radiologic evidence of cirrhosis. Established cirrhosis with active viral infection should be considered a relative contraindication to isolated renal transplantation.

Abstract
OBJECTIVE Transjugular liver biopsy using the suction method usually produces small specimens with excessive fragmentation, hence the diagnosis adequacy of specimens and the clinical impact of performing the biopsy have been questioned. An alternative biopsy needle, the Quick-Core needle system, which uses an automated trucut-type mechanism, has been shown to produce non-fragmented tissue specimens. The aim of the present study was to evaluate the safety, adequacy and clinical impact of the transjugular liver biopsy by comparing it with the standard percutaneous liver biopsy. DESIGN We recruited all patients who underwent liver biopsies by percutaneous or transjugular routes in the Department of Medicine, Princess Margaret Hospital, Hong Kong between January 1998 and December 1999. METHOD We recorded demographics and clinical features of patients, indications and complications, and the clinical impact of the liver biopsy procedure. All liver biopsy specimens were reviewed by the histopathologist, who was blinded to the approach of taking the biopsy. All variables between patients undergoing transjugular and percutaneous liver biopsies were compared. RESULTS During the study period, 50 percutaneous and 18 transjugular liver biopsies were performed. All transjugular liver biopsies were performed successfully with adequate tissue for diagnosis. Although specimens obtained by the transjugular technique tended to be shorter (10 mm v. 18 mm by the percutaneous approach, P < 0.001), the presence of fragmentation was similar to that in biopsies obtained by the percutaneous approach. Respectively, 100% and 98% of specimens obtained by the transjugular and percutaneous approaches were considered to be adequate for histological assessment. The clinical impact of transjugular and percutaneous liver procedures was comparable (89% v. 76%, P = 0.25). CONCLUSION Specimens obtained by a transjugular automated trucut needle are sufficient for histological assessment, and carry clinical impact in patient management.

Abstract
PURPOSE The efficacy and safety of transjugular liver biopsy used to obtain liver specimens in patients with coagulation disorders have been widely proven. However, histopathologic examination is not always possible because of fragmented samples provided by the aspiration technique. Recently, an automated device with a Tru-Cut-type needle was designed. In this randomized controlled trial, the use of this new device is compared with the traditional method in terms of efficacy and safety. METHOD Fifty-six patients were included in the study; 28 were randomized to undergo the aspiration technique and 28 were randomized to undergo the automated biopsy technique. RESULTS Correct positioning of the device was achieved in 93% of patients undergoing the aspiration technique and 96% of patients undergoing the automated biopsy technique (P = NS). Mean duration of the procedure and total number of passes were significantly higher in the aspiration needle group than in the automated device group (22.6 min +/- 12.6 vs 15.5 min +/- 9.4; P = .03, and 3.3 min +/- 1.9 vs 1.5 min +/- 0.63; P < .001, respectively). The number of portal tracts was significantly higher in the automated device group (4.7 +/- 2.5 vs. 2.7 +/- 3.4; P < .05). Adequate specimens for histopathologic evaluation were obtained in 26 patients in the automated device group and 24 patients in the aspiration needle group (92.8% vs 85.7%; P = NS), but a definite histopathologic diagnosis was more frequently obtained with the automated biopsy device (68% vs 43%; P = .05). No significant differences were observed in complication rates (7.14% vs. 10.7%; P = NS). CONCLUSION The automated biopsy device for transjugular liver biopsy is more effective than an aspiration needle in obtaining good samples for a definite histologic diagnosis.

Abstract
This article discusses a medical and ethical dilemma: whether to disclose a positive HIV (human immunodeficiency virus)/HCV (hepatitis C virus) coinfection to an adolescent boy without symptoms with hemophilia despite the objections of his parents. An actual case history is presented and the dilemma faced by the medical team is discussed. Numerous family conferences, all excluding the patient, held during the last 5 years discussed the medical team's obligation for full disclosure, the emerging autonomy of the patient, and the potential for medical disaster (e.g., HIV transmission) if full disclosure were not permitted. Despite this, the family did not agree to allow disclosure. The patient and parents assured us of his sexual inactivity. Legal opinion was sought from the university counsel. The dilemmas are multiple. Is there a convincing argument to insist on disclosure of these facts to this patient, particularly when there is ambiguity regarding the appropriateness of HIV and HCV treatment? Does the ethical argument that he is at potential risk for transmitting HIV/HCV outweigh the rights of the family? What are the rights of the rest of the family? What are the rights of the minor? Is it our ethical responsibility to disclose a probably fatal diagnosis?

Abstract
Liver biopsy remains an important diagnostic tool in the management of liver disease. Complications, though infrequent, are potentially disastrous. Risks and discomfort can be minimized with good technique, although prospective data to prove the superiority of one method over another are often lacking. Image direction is preferred in all cases, as is a transjugular approach when bleeding risks are judged to be high. Bleeding is essentially a random event. Outpatient liver biopsy is appropriate in almost every instance if immediate hospitalization facilities are available. It should be more widely practiced. Liver biopsies should only be done if, after thoughtful assessment, benefits are thought to exceed risks.

Abstract
PURPOSE Obtaining transjugular liver biopsy specimens with use of single-use needle systems is expensive, whereas biopsy specimens obtained with use of reusable needle systems are frequently associated with inadequate core specimens. The authors report their experience with the reusable Cook Shark Jaw biopsy needle, including diagnostic yield, complications, and cost-effectiveness. MATERIALS AND METHODS A retrospective audit was performed of a cohort of 134 patients who underwent 136 transjugular liver biopsies with use of a reusable 16-gauge Shark Jaw needle during a 30-month period. Specimen adequacy and complication rates were assessed and direct costs of expendable components calculated. Cost-effectiveness was expressed as cost-per-successful biopsy. RESULTS Biopsies were technically successful in 126 of 136 (93%) patients, with diagnostic histologic core specimens obtained in 124 of 126 (98%) patients, for an overall success rate of 91%. Complications included capsular penetration in six (4.4%) patients, cardiac arrhythmia in two (1.5%) patients, and puncture site hematoma or bleeding in 10 (7.4%) patients. Three tract embolizations were performed for capsular penetration. No instances of subcapsular hematoma, hemoperitoneum, or sepsis occurred, and no deaths were attributed to the procedure. The cost of expendable components totaled $103 per biopsy, corresponding to a cost-effectiveness of $113/successful biopsy. CONCLUSION Transjugular liver biopsy specimens obtained with use of the Shark Jaw needle have a diagnostic yield comparable to those obtained with use of single-use biopsy systems, at a substantially lower cost with no increase in serious complications.

Abstract
BACKGROUND/AIMS Liver fibrosis is one of the most important and characteristic histologic alterations in progressive and chronic liver diseases. Thus, in both clinical and experimental practice, it is fundamental to have a reliable and objective method for its precise quantification. Several semi-quantitative scoring systems have been described. All are time-consuming and produce partially subjective fibrosis evaluations that are not very precise. This paper describes the design and validation of an original image analysis-based application, FibroQuant, for automatically and rapidly quantifying perisinusoidal, perivenular and portal-periportal and septal fibrosis and portal-periportal and septal morphology in liver histologic specimens. METHODS The implemented image-processing algorithms automatically segment interstitial fibrosis areas, while extraction of portal-periportal and septal region is carried out with an automatic algorithm and a simple interactive step. For validation, all automatically extracted areas were also manually segmented and quantified. RESULTS Statistical analysis showed significant intra- and interoperator variability in manual segmentation of all areas. Automatic quantifications did not significantly differ from mean manual evaluations of the same areas. Comparison of our image analysis quantifications with staging histologic evaluations of liver fibrosis showed significant correlations (Spearman's, 0.72<r<0.83; p<0.0001) and that the latter are based more on the distribution patterns than on the quantity of fibrosis. CONCLUSIONS FibroQuant is a sensitive, precise, objective and reproducible method of fibrosis quantification, which complements semi-quantitative histologic evaluation systems. This novel tool could be of special value in clinical trials and for improving the prognosis and follow-up among patients with fibrosis-inducing hepatic diseases.
