Effect of medium chain triglycerides enriched formula on growth of biliary atresia patients after Kasai portoenterostomy. Arab J Gastroenterol 2024; 25:188-193. [PMID: 38378358 DOI: 10.1016/j.ajg.2024.01.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 01/22/2024] [Accepted: 01/27/2024] [Indexed: 02/22/2024]
Abstract
BACKGROUND AND STUDY AIMS Biliary atresia (BA) is the most common cause of neonatal cholestasis, negatively affecting nutritional status, growth, and development. It is the most frequent paediatric indication for liver transplantation. The Kasai portoenterostomy (KPE) operation is an effective procedure with favourable outcomes when performed before two months of age. The present study aimed to assess the nutritional status of patients with biliary atresia who underwent the Kasai operation and to evaluate the effectiveness of nutritional counselling using medium-chain triglyceride (MCT) formulas and proper supplementation on their nutritional status, growth, and vitamin D levels. PATIENTS AND METHODS This prospective observational study included 36 infants with biliary atresia who underwent Kasai portoenterostomy. All patients underwent clinical assessment, anthropometric evaluation, nutritional counselling, and an evaluation of vitamin D levels. Only compliant patients (22/36) were followed up after 3 and 6 months of nutritional counselling. RESULTS Z-scores for weight, triceps skinfold thickness, and mid-upper arm circumference improved significantly after three months, and the height velocity Z-score improved after six months of nutritional counselling using an MCT-containing formula and supplementations. Patients who showed an improvement in cholestasis had better responses. The initial assessment revealed low serum levels of 25-hydroxyvitamin D in 77.8 %, which increased significantly (p = 0.012). CONCLUSION Dietary intervention and supplementation with MCT and micronutrients can improve the nutritional status of children with BA following KPE.

Abstract
PURPOSE OF REVIEW Cholestasis is characterized by a conjugated hyperbilirubinemia secondary to impaired bile synthesis, transport, or excretion from the liver. It is always pathologic and can be indicative of an underlying hepatobiliary, genetic, or metabolic disorder, several of which require timely diagnosis to ensure proper management and optimal outcomes. This review provides an overview of the evaluation of cholestasis with a focus on current and emerging treatment strategies. RECENT FINDINGS Increased accessibility of next generation sequencing (NGS) allows for utilization of genetic testing early in the diagnostic process. This may alter the clinical algorithm for diagnosis of cholestatic disorders. An enhanced understanding of the underlying pathophysiology may help guide future development of targeted therapies, such as ileal bile acid transporter (IBAT) inhibitors. These were recently approved for treatment of cholestatic pruritus in patients with Alagille syndrome and Progressive Familial Intrahepatic Cholestasis. Current management of cholestasis is aimed at the biochemical consequences of impaired bile flow, including malnutrition, pruritus, and progressive fibrosis. NGS has led to an enhanced understanding of biliary pathology and may guide development of future treatment modalities based on specific gene mutations. Rapid discernment of the underlying etiology is essential as new treatment modalities emerge.

Abstract
INTRODUCTION Kasai hepatoportoenterostomy is the standard of care for children with biliary atresia, but a majority of patients progress to end-stage liver disease and require a salvage liver transplant. Given the high failure rates of the hepatoportoenterostomy operation, some have advocated for primary liver transplantation as a superior treatment approach. The aim of this study was to compare outcomes of pediatric candidates with biliary atresia listed for primary vs. salvage liver transplantation. METHODS The SRTR/OPTN database was retrospectively reviewed for all children with biliary atresia listed for liver transplant between March 2002 and February 2021. Candidates were categorized as primary liver transplant if they had not undergone previous abdominal surgery prior to listing and salvage liver transplant if they had. Salvage transplants were further categorized as early failure if listed within the first year of life or late failure if listed at an older age. RESULTS 3438 children with biliary atresia were listed for transplant during the study period, with 15% of them listed for a primary transplant, 17% for salvage transplant after early failure, and 67% after late failure. Recipients of salvage liver transplant with late failure had lower bilirubin levels and were less critically ill as demonstrated by MELD/PELD scores and hospitalization status. Correspondingly, these recipients had higher waiting list and graft survival, though this did not remain statistically significant after adjustment in multivariable models. There were no differences in waiting list, recipient, or graft survival with primary vs. salvage liver transplant after early failure. CONCLUSION Kasai hepatoportoenterostomy should remain the standard of care in biliary atresia as it may delay need for transplant beyond the first year of life in a subset of recipients and does not jeopardize subsequent transplant outcomes, even with early failure. LEVELS OF EVIDENCE Retrospective cohort study (Level III).

Abstract
Biliary atresia (BA) is a rare newborn liver disease with significant morbidity and mortality, especially if not recognized and treated early in life. It is the most common cause of liver-related death in children and the leading indication for liver transplantation in the pediatric population. Timely intervention with a Kasai portoenterostomy (KPE) can significantly improve prognosis. Delayed disease recognition, late patient referral, and untimely surgery remains a worldwide problem. This article will focus on biliary atresia from a global public health perspective, including disease epidemiology, current national screening programs, and their impact on outcome, as well as new and novel BA screening initiatives. Policy challenges for the implementation of BA screening programs will also be discussed, highlighting examples from the North American, European, and Asian experience.

Abstract
INTRODUCTION Age at Kasai portoenterostomy (KPE) has been identified as a predictive factor for native-liver survival in patients with biliary atresia (BA). Outcomes of pediatric liver transplantation (LT) have improved over recent years. It has been proposed to consider primary LT as a treatment option for late-presenting BA infants instead of attempting KPE. We present our experience with patients older than 90 days undergoing KPE. MATERIALS AND METHODS A retrospective chart review of patients with BA undergoing KPE at our institution between January 2010 and December 2020 was performed. Patients 90 days and older at the time of surgery were included. Patients' characteristics, perioperative data, and follow-up results were collected. Eleven patients matched the inclusion criteria. Mean age at KPE was 108 days (range: 90-133 days). RESULTS Postoperative jaundice clearance (bilirubin < 2 mg/dL) at 2-year follow-up was achieved in three patients (27%). Eight patients (73%) received a liver transplant at a mean of 626 days (range: 57-2,109 days) after KPE. Four patients (36%) were transplanted within 12 months post-KPE. Two patients died 237 and 139 days after KPE due to disease-related complications. One patient is still alive with his native liver, currently 10 years old. CONCLUSION Even when performed at an advanced age, KPE can help prolong native-liver survival in BA patients and offers an important bridge to transplant. In our opinion, it continues to represent a viable primary treatment option for late-presenting infants with BA.

Abstract
BACKGROUND To evaluate the significance of portosystemic shunts and associated long-term outcomes in living donor liver transplant (LDLT) among pediatric patients. METHODS Retrospective review of 121 pediatric patients who underwent LDLT between May 1994 and December 2015 at Taiwan Kaohsiung Chang Gung Memorial Hospital. Pre- and postoperative computed tomography images of the liver were reviewed, and portal vein complications were assessed. RESULTS Ninety-seven pediatric patients were included in the study, and 70 had portosystemic shunts before transplant. Thirty-three patients have portal systemic shunt (PSS) 6 months after transplant (mean [SD] shunt size, 4.59 [1.98] mm). Thirty-seven patients' portosystemic shunts closed spontaneously (mean [SD] shunt size, 3.14 [1.06] mm). Smaller PSSs tend to close spontaneously with a cutoff point of 3.35 mm by receiver operating characteristic curve (P = .01). Patients with PSS have more portal vein complications than those without PSS (44.3% vs 11.1%, P = .02). Among PSS recipients, patients with portal vein complications tend to have larger PSS size (mean [SD], 4.14 [1.96] mm vs 3.59 [1.48] mm), although the difference is not statistically significant (P = .19). CONCLUSIONS In pediatric patients, preoperative portosystemic shunts are significantly correlated with portal venous complications, some of which require minimal interventions after LDLT with good outcomes. Shunts larger than 3.35 mm tend to persist after transplant with increased portal venous complications.

Abstract
BACKGROUND The age at Kasai portoenterostomy (KPE) was reported to correlate with the prognosis of patients with biliary atresia (BA) and that a late KPE is bounded to be failure. Herewith, we reported the outcome of patients receiving KPE after day 70 of life. In addition, the prognostic indicators were evaluated. MATERIALS AND METHODS This was a retrospective analysis and all BA patients receiving KPE after day 70 of life in a tertiary centre between 1980 and 2018 were evaluated. RESULTS A total of 164 KPE procedures were performed during the study period and 62 cases were done after day 70 of life which were included in this study. The median follow up period of these patients was 10.6 years (range: 4.5 to 41.5 years). Thirty-nine patients (62.9%) patients were able to achieve jaundice clearance at 6 months after KPE. The NLS rate was 53.2% (n = 33) as recorded at the time of writing. There was no statistical difference in the age at KPE between native liver survivors and patients requiring liver transplant. For complications among the native liver survivors (n = 33), portal hypertension and recurrent cholangitis were found in 63.6% and 30.3% of these patients. There was also no significant difference in the age at KPE between those who developed portal hypertension and recurrent cholangitis (p = 0.451 and p = 0.173 respectively). Regarding the prognostic indicators in predicting NLS, pre-KPE bilirubin, alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) were significantly higher among patients requiring liver transplant (p = 0.012, =0.011 and =0.017 respectively). The bilirubin level at 6 months after KPE was also higher among patients who required liver transplant (p = 0.016). CONCLUSION More than half of the BA patients can survive for 10 years with their native liver despite KPE was performed after day 70 of life. However, they have a higher chance to develop BA-related complications. The level of pre-KPE bilirubin and ductal enzymes as well as post-KPE bilirubin are prognostic indicators to predict NLS.

Abstract
BACKGROUND The epidemiology and outcomes of biliary atresia (BA) have been well-documented in national cohorts from two main ethnicities, namely, the Asian Orientals and Caucasians, with incidence ranging from 1 in 5,000 to 1 in 9,000 live births in East Asia and 1 in 15,000 to 19,000 live births in Europe and North America. OBJECTIVE We report the first nationwide BA study outside North America, Europe, and East Asia to describe the epidemiology and outcomes of BA in Saudi Arabia. METHODS A national database of BA cases diagnosed between 2000 and 2018 was analyzed. We assessed clearance of jaundice (bilirubin <20 μmol/L) in all cases that underwent Kasai portoenterostomy (KPE). We then estimated survival using the Kaplan-Meier method with endpoints of liver transplantation (LT), death, or survival with native liver (SNL). RESULTS BA was diagnosed in 204 infants (106 females; 10% pre-term). The incidence of BA was 1 in 44,365, or 2.254 in 100,000 live births (range, 0.5-4 in 100,000). Polysplenia was diagnosed in 22 cases (11%). The median age at referral was 65 days. A total of 146 children (71.5%) underwent KPE at a median age of 70 days. Clearance of jaundice was achieved in 66 of the 146 (45%) infants. The 10-year SNL after KPE was 25.5%, and the overall 10-year estimated survival was 72.5%. The Kaplan-Meier survival curves for patients undergoing KPE at the age of <60, 61-90, and >90 days showed a SNL rate at 51.6, 33, and 12.5%, respectively, at 5 years (P < 0.001). The 2-, 5-, and 10-year post-LT survival rates were 92.5, 90.6, and 90%, respectively. Undergoing an initial KPE did not impact negatively on the overall LT survival rate when compared to BA cases that underwent primary LT (P = 0.88). CONCLUSION The incidence rate of BA in Saudi Arabia is lower than the incidence reported elsewhere. Late referral of BA cases remains a problem in Saudi Arabia; as a result, the SNL rate was lower than reported by other national registries. Hence, national policies devoted to timely referral and earlier age at KPE are needed.

Abstract
BACKGROUND Persistent inflammation induced by viral infection may contribute to the pathogenesis of biliary atresia (BA). Moreover, CD4+ helper cells and CD8+ killer cells are the main effector cells involved in BA and intrahepatic bile duct injuries. OBJECTIVE Thus, we aimed to explore the dynamics of inflammatory cell infiltration and inflammation-regulated pathways in liver-specific inflammatory responses. METHODS Neonatal Balb/C mice were intraperitoneally infected with 1 × 106 PFU rhesus rotavirus (RRV; BA + group), 1 × 105 PFU RRV (BA- group), or DMEM (control group). Mice were sacrificed 7 or 14 days post-infection and their bile ducts, livers, and spleen-derived tissues were examined via H & E staining. The number of CD4+T lymphocytes helper cells (CD4+Th), CD8+T lymphocytes killer cells (CD8+Tc), natural killer (NK) cells, and macrophages (Mac) in the liver and spleen were quantified by flow cytometry. The expression of inflammatory genes was analyzed via a PCR-array. Western blotting was conducted to quantify the protein expression of Notch receptor active fragments (NICD). Finally, some mice were injected with DAPT (a γ-secretase inhibitor) 12 h post-infection followed by analysis of liver and bile duct tissues after 14 days. RESULTS The numbers of CD4+Th cells were increased in the livers of BA- mice after 14 days (P < 0.05). After RRV infection, the number of CD8+Tc, CD4+Th, NK, and Mac were increased in the livers of BA + mice after 7 and 14 days. Notably, NK cell numbers remained elevated in the BA + group, but the number of Mac first increased and then decreased in both the treatment groups. PCR-array analyses indicated that the expression of many genes related to T cell proliferation and differentiation significantly increased in the livers of BA. The most upregulated gene was Jagged2 (20.34-fold). Increased NICD (Notch receptor active fragments) protein expression was found in the BA + group. Finally, DAPT injection could reduce inflammation, CD8+Tc infiltration, NICD expression, and bile duct damage after RRV infection. We found that CD8+Tc played the most important role in damaging bile ducts and promoting BA. CONCLUSION The DAPT-based intervention could reduce expression of CD8+Tc and bile duct damage in BA mouse livers post-RRV infection. We believe that the Notch signaling pathway regulates CD8+Tc functions and inflammatory dynamics in BA mouse livers.

Abstract
INTRODUCTION Age of patient and experience of biliary atresia (BA) center are well-known factors associated with early jaundice clearance (EJC) after Kasai portoenterostomy (KPE) in infants with BA. This study focused on the impact of age and surgeon factor on the short-term outcome after KPE within a single center. MATERIALS AND METHODS Fifty-four consecutive infants (18 boys and 36 girls) who underwent KPE from January 2010 to January 2020 were reviewed. KPE was performed in the earliest available operative session once the initial work-up was completed. In group A (n = 41), KPE was performed by surgeon A. In group B (n = 13), KPE was performed by specialists under the supervision of surgeon B (who is the mentor of surgeon A) when surgeon A was not available for operation. The demographics of patients, the EJC (total bilirubin <20 μmol/L within 6 months of KPE), and 2-year native liver survival (NLS) between the two groups were studied. RESULTS The median age at operation was 52 days (range 26-135 days). The overall EJC rate and 2-year NLS were 85.2 and 89.4%, respectively. Group A (p = 0.015) and male gender (p = 0.029) were statistically associated with EJC but not the age at operation (p = 0.101). Group A was also statistically associated with superior 2-year NLS (p = 0.047). CONCLUSION Balancing between the impact of age at operation and the experience of surgeon on the outcome after KPE, our result suggested that KPE may be deferred until a more experienced surgeon to operate.

Abstract
OBJECTIVES To describe the clinical, histopathologic, and outcomes data for a cohort of patients with biliary atresia (BA), and to identify the factors affecting survival. METHODS This was a cross-sectional study of all BA patients diagnosed between 1999 and 2017. Clinical, biochemical, imaging, and histopathologic data were analyzed, and Kaplan-Meier survival rates were compared to identify potential prognostic factors. RESULTS We evaluated 23 patients. The median age at the Kasai procedure was 77 ± 34 days, and the median overall survival was 12.5 ± 65 months. Thirteen (56%) patients survived with their native livers, 3 (13%) received a transplant, and 6 died (26%) while awaiting a transplant. Cholangitis and the use of ursodeoxycholic acid were associated with longer survival, while impaired synthetic function was associated with shorter survival. CONCLUSIONS Most patients presented late for the Kasai procedure. The survival rate with the native liver was comparable to other cohorts. Therefore, clinicians are encouraged to refer for the Kasai procedure even with late presentation (between 60 and 90 days), provided there is no hepatic decompensation.

Abstract
Kasai portoenterostomy(KPE) is the treatment of choice for the fatal devastating infantile type III biliary atresia (BA). The study aimed to analyze short-and long-term outcomes after this procedure and their predictors in a tertiary center. METHODS We retrospectively analyzed 410 infants who underwent KPE for type III BA in the period from February 2000 to December 2019. The overall male/female ratio was 186/224. RESULTS The early (>6months) complications involved 187(45.6%) of our infants with a higher incidence of early cholangitis that affected 108(26.3%) of them. The jaundice clearance at the 6th post-operative month that reached 138(33.7%) of them had an independent correlation with mild portal tracts ductal and/or ductular proliferation, using postoperative steroids therapy, and absence of early postoperative cholangitis. The early infant mortality that affected 70(17.1%) of our patients was mostly from sepsis. On the other hand, late (<6months) patients complications and mortalities affected 256(62.4%) and 240(58.5%) of patients respectively; moreover, liver failure and sepsis were the most frequent causes of late mortalities in non-transplanted and transplanted cases respectively. Lastly, the long-term (20-year) native liver survival (NLS) that reached 91(22.2%) of patients had an independent correlation with age at operation ≤ 90 days, higher preoperative mean serum alb, portal tract fibrosis grades F0 and F1, absence of intraoperative bleeding, absence of post-operative cholangitis, the occurrence of jaundice clearance at the 6th postoperative month and absence of post-operative portal hypertension (PHN). CONCLUSIONS Sepsis had a direct effect on early and late patient mortalities after Kasai operation for type III BA; moreover, patient age at operation<90 days, higher fibrosis grades, the occurrence of postoperative cholangitis and PHN, and persistence of post-operative jaundice had negative insult on long-term postoperative outcome. So, it is crucial to modulate these factors for a better outcome.

Abstract
PURPOSE The outcome predictors of Kasai portoenterostomy (KPE) for biliary atresia (BA) are controversial. This study aimed to identify possible short-term outcome predictors of KPE for BA in infants. METHODS This retrospective study included infants with BA who underwent KPE between January 2015 and December 2017 and were followed up for at least 6 months after surgery at the Pediatric Hepatology Unit, Cairo University Pediatric Hospital, Egypt. The short-term outcome was jaundice clearance within 6 months following surgery. All data were compared between the jaundice free group and those with persistent jaundice to identify the predictors of jaundice clearance. RESULTS The study included 75 infants. The mean age at the time of surgery was 82.43±22.77 days (range, 37-150 days), and 28 (37.3%) infants cleared their jaundice within 6 months postoperative. Age at surgery did not significantly affect the outcome (p=0.518). Infants with persistent jaundice had significantly higher pre-operative levels of aspartate aminotransferase (AST) than those who were jaundice free (p=0.041). Receiver operating characteristic curve analysis showed that preoperative AST ≤180 IU/L was predictive of a successful KPE, with sensitivity 74.5% and specificity 60.7%. Infants with bile plugs in liver biopsy had a 6-fold higher risk of persistent jaundice than those without bile plugs (95% confidence interval: 1.59-20.75, p=0.008). CONCLUSION Jaundice clearance after KPE for BA can be predicted using preoperative AST and presence of bile plugs in liver biopsy.

Abstract
BACKGROUND To determine a very early predictive biomarker after hepatoportoenterostomy (HPE) for the prediction of native liver survival in biliary atresia (BA) patients. METHODS A retrospective chart review was conducted of BA patients in our hospital between August 2000 and April 2019. The serum total bilirubin (T-bil), direct bilirubin, and gamma-glutamyl transferase level 1 week after HPE were analyzed. The clinical outcome predictors were investigated. RESULTS A total of 90 BA patients were recruited. Receiver operating characteristic curve analysis showed that a post-HPE 1-week T-bil level ≤4.85 mg/dL predicted jaundice-free after HPE (P = 0.02). BA patients with a post-HPE 1-week T-bil ≤4.85 mg/dL were more likely to be jaundice-free within 3 months of HPE (odds ratio = 3.53; P = 0.006). Kaplan-Meier plot analysis showed that the likelihood of native liver survival and jaundice-free native liver survival were significantly higher in BA subjects with a post-HPE 1-week T-bil ≤4.85 mg/dL than in other subjects (P = 0.01 and 0.01, respectively). CONCLUSIONS The serum post-HPE 1-week T-bil level may predict the long-term outcome in BA patients. A post-HPE 1-week T-bil ≤4.85 mg/dL correlated with better native liver survival and jaundice-free native liver survival in BA patients.

Abstract
For children with BA who do not benefit from Kasai surgery, the only therapeutic option is liver replacement and transplantation. The very decision to proceed for transplantation is a crucial point in time because it is the first step toward the preparation for the transplantation. The former time point is defined in this analysis as "intent-to-transplant" care pathway. In the life of every BA candidate for liver replacement, this point in time varies and mostly depends on the decision of their primary caring teams-about when to switch from supportive care to transplant, and thus to refer to a transplant center. This intent-to-transplant analysis of a series of 101 consecutive infants that were referred to a single transplant team showed that excellent overall outcome (97% survival) has been achieved overall. However, three deaths occurred that were clearly related to a late referral. This analysis and recent observations from other centers strongly support that the timing for referring these children to a transplant center and/or deciding to list them on the waiting list is currently too late and should be anticipated to what it is currently. This paradigm shift in the intention-to-transplant children is likely necessary for giving a better chance to an increased number of children and impacts positively on the general outcome. Networking and defining new tools for a rapid recognition of the infants who need early transplantation are necessary; centralization of these children may be helpful to achieve better outcomes than currently observed.

Abstract
OBJECTIVE To evaluate the effects of Kasai procedure (hepatic portoenterostomy) on living donor liver transplantation (LDLT) for children with biliary atresia (BA). METHODS From January 2006 to January 2014, 150 children with BA were treated with LDLT in China. The children were categorized into pre-Kasai and non-Kasai groups, based on whether they had previously undergone Kasai procedure. Clinical data were retrospectively analyzed, and the difference in postoperative survival was compared between the groups. Preoperative data, including height, weight, serum bilirubin, and pediatric end-stage liver disease score, and perioperative blood loss, operation duration, incidence of postoperative surgical complications including vascular complications, bile duct complications, lymphatic fluid leakage, and digestive tract fistula were compared between the groups. RESULTS In total, 89 and 61 children were categorized in the pre-Kasai and non-Kasai groups, respectively. The 1-, 6-, and 12-month survival was 97.8%, 95.4%, and 95.4% for the Kasai group, and 98.4%, 96.7%, and 96.7% for the non-Kasai group, respectively (P > 0.05). The differences in mean operation duration and mean blood loss, and the incidences of outflow tract obstruction, portal vein stenosis, hepatic artery thrombosis, bile duct complications, lymphatic fluid leakage, and digestive tract fistula were not statistically significant between the groups (P > 0.05). CONCLUSION Kasai procedure could effectively delay the requirement of liver transplantation. In light of previous findings that Kasai procedure could significantly improve the liver transplantation-free survival of children with BA, we suggest that Kasai procedure should be used as a first-line treatment method for this condition. TYPE OF STUDY Treatment Study. LEVEL OF EVIDENCE Level III.

Does Supersonic Shear Wave Elastography Help Differentiate Biliary Atresia from Other Causes of Cholestatic Hepatitis in Infants Less than 90 Days Old? Compared with Grey-Scale US. BIOMED RESEARCH INTERNATIONAL 2019; 2019:9036362. [PMID: 31275991 PMCID: PMC6582890 DOI: 10.1155/2019/9036362] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Revised: 04/12/2019] [Accepted: 04/30/2019] [Indexed: 12/24/2022]
Abstract
Purpose To investigate the diagnostic performance of shear wave elastography (SWE) for measuring liver stiffness to identify and differentiate biliary atresia (BA) from cholestatic hepatitis in infants younger than 90 days. Methods A total of 138 infants younger than 90 days with cholestatic hepatitis were examined by SWE. The infants were subclassified into BA and nonbiliary atresia (non-BA) groups. Receiver operating characteristic (ROC) analysis was used to determine the sensitivity and specificity of hepatic Young's modulus measurements, the ultrasonic findings in the differential diagnosis of suspected BA, and the cut-off value to diagnose BA. Results In all infants with cholestatic hepatitis, the cut-off value of hepatic Young's modulus to differentiate the BA group from the non-BA group was 12.35 kPa and the area under the ROC curve (AUC) was 0.937, with a sensitivity of 84.3% and a specificity of 89.7%; nevertheless the AUC of the abnormal gallbladder (AbGB) was 0.940, with a sensitivity of 96.1% and a specificity of 92.0%. In the parallel test, triangular cord (TC) sign combined with AbGB had the best diagnostic performance and the AUC was 0.960, with a sensitivity of 100% and a specificity of 92.0%. In the serial test, SWE combined with AbGB achieved the best diagnostic performance; the AUC was 0.902, the sensitivity and specificity were 80.4% and 100%, respectively. Conclusions SWE could not only help differentiate BA from cholestatic hepatic diseases but also increase the diagnostic specificity when combined with grey-scale ultrasound in the serial test.

Abstract
Biliary atresia is a progressive inflammatory sclerosing disease of the bile ducts in the neonatal liver. Without surgical intervention these patients are destined to succumb to the disease. The development of the hepatoportoenterostomy in 1959 and liver transplantation in 1963 ushered a new era of success treating these patients. While many surgical modifications and adjuncts to treatment have been attempted over the last 50 years, the mainstay of treatment to give the child the best chance at prolonged survival with the native liver is a properly performed operation, in a timely fashion, with minimal post-operative complications. This review presents the authors current practice guideline to achieve these goals.

Abstract
BACKGROUND/AIMS Data from Western countries indicate that biliary atresia (BA) is the leading cause of end-stage liver disease in children and the most common indication for liver transplantation (LT) in the pediatric population. There is no data on the epidemiology and outcome of BA in Saudi Arabia. The main objective of our study was to understand the clinical and epidemiological characteristics and outcome of BA in the Saudi population. PATIENTS AND METHODS We retrospectively reviewed the database of infantile cholestasis cases that presented to our center from 2008 to 2015 and identified BA cases. Data on clinical, biochemical, imaging, and histopathological characteristics were collected by chart review. The two primary study outcomes were (1) successful Kasai portoenterostomy (KPE) defined as resolution of jaundice (total serum bilirubin <20 μmol/L) and (2) survival with native liver. RESULTS Over the study period, we evaluated 450 cases of infantile cholestasis. In all, 21 cases (11 males) were diagnosed with BA (4.7%). BA cases were first seen by pediatric gastroenterologists at a median age of 65 days. KPE was performed in 12 cases at a median age of 73 days. Successful KPE was achieved in four cases (33%). Five of the remaining eight cases had LT and three died before LT. Nine of the 21 BA cases were denied KPE and had primary LT at median 8 months of age. The native liver 4-year survival rate was 14.3% and the overall survival rate was 81%. CONCLUSION BA is an uncommon cause of infantile cholestasis in Saudi Arabia. Our study provides a snapshot of the epidemiology of BA in Saudi Arabia that is characterized by late referral to pediatric gastroenterologists and poor outcome without LT.

Abstract
Aims: The aim of our study was to compare the outcome of Kasai portoenterostomy (KPE) in children with biliary atresia (BA) older than 90 days to children less than 90 days and to study its safety and efficacy in children older than 90 days. Subjects and Methods: Relevant data were collected from our prospectively maintained database of all children with BA who underwent KPE over a 5-year period. Children were divided into two groups: Group 1 ≤90 days and Group 2 >90 days. Data analyzed and compared included total and direct bilirubin, aspartate aminotransferase-to-platelet ratio index (APRI), and the outcome of procedure which was defined as a serum direct bilirubin <2 mg/dl within 6 months after surgery. Standard statistical tests were used for analysis. Results: Out of 62 children, 45 children were in Group 1 and 17 children were in Group 2. Children in Group 2 had similar total and direct bilirubin compared to children in Group 1. APRI, an indicator of fibrosis, was significantly increased in Group 2 (P = 0.08). About 47% of children in Group 2 had Stage III fibrosis on liver histology compared to 22% of children in Group 1. None of the children in Group 2 had synthetic liver failure (refractory ascites, hypoalbuminemia, or coagulopathy unresponsive to Vitamin K) or portal hypertension. KPE was successful in 29.4% of children in Group 2 and 44% in children in Group 1. There was no perioperative mortality in our group. Conclusions: KPE was successful in a third of children over 90 days of age and can be safely performed in this group. In the absence of synthetic liver failure, age should not be a disqualification for performing KPE.

Abstract
Objectives Recently, a scoring system has been developed to predict which patients with biliary atresia (BA) who underwent a Kasai procedure should be considered for liver transplant. Here, we applied the scoring system to predict the survival of BA patients following the Kasai procedure at Dr. Sardjito Hospital, Yogyakarta, Indonesia from January 2012 to January 2016. Results There were 26 patients, of whom 14 were males and 12 females. Outcomes of BA patients after the Kasai surgery were 15 survived and 11 died. There were significant associations between ascites and sepsis with the liver transplant score of ≥ 8 (p value = 0.006 and 0.014, respectively), whereas post-operative bilirubin level, ALT level, prothrombin time, cirrhosis, esophageal varices, portal hypertension, and cholangitis did not significantly correlate to the score. The patients with a score ≥ 8 have a relatively greater risk by 3.5-fold to die compared with patients with a score < 8, but it did not reach a significant level (p value = 0.13). In conclusions, the incidence of ascites and sepsis might predict the poor prognosis of BA patients following the Kasai procedure. Moreover, patients with a score ≥ 8 are prone to die after the Kasai surgery if they do not undergo a liver transplant.

Abstract
Cholestatic jaundice in the first few weeks of life may herald potentially life-threatening pathology. It is therefore incumbent upon the pediatric practitioner to have a high index of suspicion for severe disease when investigating jaundice in a young infant. This article outlines the epidemiology, pathophysiology, differential diagnosis, and diagnostic workup for both the most common and the most severe causes of cholestasis in the neonatal period.

Abstract
BACKGROUND Biliary atresia (BA) is typically treated by Kasai portoenterostomy (KPE), and there is a relationship between age at surgery and outcome. We hypothesize that previous abdominal surgery (PAS) for associated congenital intestinal conditions could be used to identify BA earlier, perhaps improving prognosis. METHODS A retrospective case note review was performed of all BA patients at a single centre from 1999 to 2016. Demographics and clinical outcome data were collected. Additional data on laparotomy, parenteral nutrition, and referral were collected from patients who underwent PAS. Data are median (range). MAIN RESULTS Two-hundred-and-fifty-seven children were reviewed. Of these, 16 (6.2%) underwent PAS on day 3 (0-23), during which 5 atretic gallbladders were noted. Gallbladder appearance was not referenced in the operation notes of 8 infants. Jaundice and acholic stools were noted at 4 (0-56) days and 21 (0-60) days, respectively. Age at KPE was comparable between PAS and the other patients (50 vs. 51days; P=0.78), but native liver survival was significantly lower after PAS (p<0.0001). Mortality rate was higher in PAS patients (25% vs. 4.5%; P=0.0007). Survival was unaffected by early referral of patients on finding an atretic gallbladder at surgery. CONCLUSION About 6% of infants have already undergone abdominal surgery for biliary atresia associated intestinal anomalies. Routine gallbladder examination at time of laparotomy could have aided earlier diagnosis and treatment of biliary atresia in up to 80% of patients in this cohort. However, our data suggest that clinical outcome is poorer in biliary patients who undergo prior abdominal surgery and is not improved by earlier referral. LEVEL OF EVIDENCE Prognostic study: Level III.

Abstract
BACKGROUND So far, there has been no epidemiological study on whether long-term native liver survival (NLS) in infants with biliary atresia (BA) is associated with use of a stool color card (SCC). METHODS A case-control study was performed, involving two associations for patients with BA in Japan. Participants were patients with BA who were born and underwent their first open Kasai procedures (KP) between August 1994 and March 2011, and who were also members of either of two associations for patients with BA in Japan. SCC users were classified as cases and SCC non-users as controls. RESULTS Mean age at the time of the first open KP was 59.7 and 68.2 days in SCC users and non-users, respectively (P < 0.05). According to Kaplan-Meier analysis, the probability of NLS at 12.5 years was 48.5% and 36.6% in SCC users and non-users (P < 0.05), respectively. On Cox proportional hazard modeling, not using an SCC was harmful to long-term NLS (hazard ratio, 2.61; 95% CI: 1.20-5.70; P = 0.016), adjusted for sex, age of timing of KP and type of BA. CONCLUSIONS Long-term NLS is associated with SCC for early detection, but not associated with age or a threshold of age at KP (<90 days) in patients with BA.

Abstract
Biliary atresia (BA) is a progressive, fibro-obliterative disorder of the intrahepatic and extrahepatic bile ducts in infancy. The majority of affected children will eventually develop end-stage liver disease and require liver transplantation (LT). Indications for LT in BA include failed Kasai portoenterostomy, significant and recalcitrant malnutrition, recurrent cholangitis, and the progressive manifestations of portal hypertension. Extrahepatic complications of this disease, such as hepatopulmonary syndrome and portopulmonary hypertension, are also indications for LT. Optimal pretransplant management of these potentially life-threatening complications and maximizing nutrition and growth require the expertise of a multidisciplinary team with experience caring for BA. The timing of transplant for BA requires careful consideration of the potential risk of transplant versus the survival benefit at any given stage of disease. Children with BA often experience long wait times for transplant unless exception points are granted to reflect severity of disease. Family preparedness for this arduous process is therefore critical. Liver Transplantation 23:96-109 2017 AASLD.

Abstract
Jaundice is a key manifestation of hepatobiliary disease in all age groups. Jaundice is a common finding in the first 2 weeks after birth, occurring in 2.4% to 15% of newborns. The neonatal liver is at increased susceptibility to cholestasis, with an incidence ranging from 1 in 2,500 to 1 in 5,000 live births. Etiologies vary, but the most common is biliary atresia. In 2004, the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition published guidelines for the evaluation of cholestasis that clearly stated any infant with jaundice persisting beyond age 2 weeks (3 weeks in breast-fed infants with an otherwise normal history and physical examination) should be evaluated with a fractionated serum bilirubin level. Prompt evaluation, diagnosis, and intervention are vital to optimize timely intervention and improve clinical outcomes. This article discusses the etiology, diagnosis and evaluation of cholestatis in infants. [Pediatr Ann. 2016;45(12):e414-e419.].

Abstract
BACKGROUND Biliary atresia (BA) is a serious liver disease with uncertain prognosis. The objective of this study was to investigate prognostic values of the >20 % decrease in serum total bilirubin (TB) at 7th day post-op regarding early outcome and 5-year survival with native liver in BA. METHODS Biliary atresia patients undergoing Kasai operation between 2000 and 2014 were reviewed. The ratio of serum TB at 7th day post-op to pre-op TB levels (TB7/TB0) was calculated for every patient. TB7/TB0 ratio of <0.8 indicated the >20 % decrease in serum TB. At 6th month following Kasai operation, outcome of BA patients were categorized into good outcome (TB < 2 mg % or clinically jaundice free) and poor outcome (TB > 2 mg % or clinically jaundice). For outcome analysis, logistic regression was used. For survival analysis, Cox regression was applied. RESULTS There were 133 BA patients (M:F = 68:65) undergoing Kasai operation. Median age at surgery was 79 days. BA patients with TB7/TB0 ratio of <0.8 were found in 38 %. Outcome at 6-month post-op could be evaluated in 126 patients (good: poor = 68:58). The 1-, 3- and 5-year survival rates with native livers were 85, 70 and 65 %, respectively. The median overall survival with native livers was 164 months. Median follow-up time was 87 months. Logistic regression showed that gender and age at operation were not significant factors impacting on early outcome (p > 0.05). However, TB7/TB0 ratio of <0.8 was an independent factor for good outcome (Odds ratio = 3.0, p = 0.006). Cox regression analysis demonstrated that 5-year survival rate was significantly correlated with TB7/TB0 ratio of <0.8 (HR = 0.46, 95 % CI 0.23-0.91, p = 0.025) and outcome at 6th month post-op (HR = 0.05, 95 % CI 0.01-0.15, p < 0.001). CONCLUSIONS The >20 % decrease in serum TB at 7th day post-Kasai is a predictor for good outcome. BA patients with TB7/TB0 of <0.8 had 5-year survival with native livers significantly higher than those with the ratio of >0.8.

Abstract
NEED AND PURPOSE OF REVIEW Biliary atresia is a progressive obstructive cholangiopathy and is fatal if left untreated within 2 years of life. Delay in referral is because of difficulties in differentiating it from physiologic jaundice and identifying an abnormal stool color. This paper presents an overview on the diagnosis and discusses the current strategies in the management of this disease in developing countries. METHODS Articles were retrieved from the PubMed database using the terms biliary atresia, Kasai portoenterostomy and pediatric liver transplantation. Contents of the article are also based on personal experience of the authors. CONCLUSION A national screening program using stool color cards as part of standard care in the neonatal period will greatly improve early detection of biliary atresia. Outcomes will improve if it is diagnosed at the earliest after birth, the child is referred to an experienced pediatric hepatobiliary unit for evaluation, and undergoes an early Kasai procedure. If an early Kasai portoenterostomy is performed, nearly half of all children survive into adolescence, and about one-third are likely to have a long-term, symptom-free life with normal liver biochemistry. Sequential treatment combining Kasai as first line and liver transplantation as second line results in 90% survival for children with biliary atresia.

Abstract
BACKGROUND We aimed to evaluate the diagnostic value of anti-smooth muscle antibodies (ASMA) and two liver markers (gamma-glutamyl transpeptidase [GGT] and alkaline phosphatase [ALP]) for differentiating between patients with extrahepatic biliary atresia (EHBA) and idiopathic neonatal hepatitis (INH). MATERIALS AND METHODS During April 2010-2011, all infants at 2 weeks of age who were diagnosed with cholestasis and admitted to Children's Hospital of Tabriz were enrolled. Based on the results of physical examination, laboratory, imaging and pathological studies, neonates were divided into two groups (EHBA and INH). Receiver operating characteristics analysis was used to define sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy for ASMA, GGT and ALP. RESULTS Thirty neonates with cholestasis (18 with EHBA and 12 with INH) and mean age of 54.66 25.86 days were enrolled. Total and direct bilirubin, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase and ASMA titres were highly not significant (P > 0.05) in patients with INH. GGT (P = 0.008) and ALP (P = 0.01) had statistically significant differences that were higher in patients with EHBA. The sensitivity, specificity, PPV and NPV, accuracy, LR+ and LR- of SMA in differentiating cases with BA were 66.7%, 75%, 80% 60%, 70%, 2.68 and 0.44, respectively. For GGT, the values were 88.9%, 66.7%, 80%, 80%, 79.1%, 3.08 and 0.31, respectively. Finally, for ALP, the values were 77.8%, 75%, 82.4%, 69.2%, 80%, 2.66 and 0.24, respectively. CONCLUSION Our study showed that ASMA may be a useful biomarker for differentiation of EHBA from INH. Further studies with larger samples are recommended for confirming the results of this study.

Abstract
OBJECTIVES Biliary atresia (BA) is the most common cause of liver transplantation in children. The earlier the treatment is done, the better the prognosis. The aim is to evaluate the impact of late diagnosis in children with BA, including the histopathological findings and success rate of biliary drainage in patients submitted to hepatic portoenterostomy (HPE). MATERIALS AND METHODS A retrospective study of cases of BA in the Department of Pediatric Surgery, Federal University of São Paulo (UNIFESP) between 1998-2011. We found 63 cases of BA; of these, 42 underwent HPE and 21 were referred for liver transplantation. Clinic and pathologic data were evaluated. RESULTS The HPE was performed with a mean age of 86.5 days, with 16.6% having the operation at 60 days or earlier; 59.2% between 61 and 90 days; and 23.8% after 90 days. Successful biliary drainage occurred in 31% of surgeries, Mean days when HPE drained was 69.1 days, and 94.3 days when the surgery did not drain (P = .05). All patients who were successfully drained, did not have grade IV fibrosis on histology. In cases in which surgery was performed after 60 days that had not drained, 25% had grade IV fibrosis on biopsy (P = .0469). CONCLUSION The age of HPE relates to better prognosis of the disease. It was found that the rate of grade IV fibrosis is higher in no drainage patients. All patients with grade IV fibrosis had no biliary drainage.

Abstract
BACKGROUND Neonates with cholestasis may undergo many tests before biliary atresia (BA) or an alternative diagnosis is reached, and delayed intervention may worsen outcomes. An optimal diagnostic approach to reduce risk, cost, and delay has yet to be defined. The purpose of this study was to develop an algorithm that rapidly and accurately excludes BA for infants with cholestatic jaundice. METHODS A single-center retrospective comparison of diagnostic workup was made between cholestatic infants with BA, and those without BA who underwent hepatobiliary iminodiacetic acid (HIDA) scan during admission. Patients were born between 2000 and 2010 and those older than 100days at assessment were excluded. Sensitivity and specificity analysis of predictive variables was performed and an algorithm constructed. RESULTS There were 45 BA and 167 non-BA patients. Some variables were 100% sensitive for the exclusion of BA: conjugated bilirubin <2.5mg/dL, gamma-glutamyl transpeptidase <150U/L, excretion on HIDA, or a normal percutaneous cholangiogram. Clinical variables and ultrasound were less useful as screening tests owing to low specificity and sensitivity, respectively. Liver biopsy was 98% sensitive and 84% specific in the diagnosis of BA. An algorithm was constructed that rules out BA with a negative laparotomy rate of 3-22%. CONCLUSION We propose a screening algorithm for infants with conjugated hyperbilirubinemia that permits efficient exclusion of BA with minimal invasive testing and with a low risk of negative laparotomy. This algorithm now requires prospective evaluation to determine its diagnostic accuracy and its ability to reduce hospital costs, patient morbidity, and time to Kasai portoenterostomy in patients with BA.

Abstract
BACKGROUND & AIMS The dilemma of early diagnosis of biliary Atresia (BA), particularly distinguishing it from other causes of neonatal cholestasis is challenging. The aim was to design and validate a scoring system for early discrimination of BA from other causes of neonatal cholestasis. METHODS A twelve-point scoring system was proposed according to clinical, laboratory, ultrasonographic, and histopathological parameters. A total of 135 patients with neonatal cholestasis in two sets were recruited to design (n=60) and validate (n=75) a scoring system. Parameters with significant statistical difference between BA (n=30) and non-BA (n=30) patients in the design set were analyzed by logistic regression to predict the presence or absence of BA then a scoring system was designed and validated. RESULTS The total score ranged from 0 to 37.18 and a cut-off value of >23.927 could discriminate BA from other causes of neonatal cholestasis with sensitivity and specificity of 100% each. By applying this score in the validation set, the accuracy was 98.83% in predicting BA. The diagnosis of BA was proposed correctly in 100% and the diagnosis of non-BA was proposed correctly in 97.67% of patients. By applying this model, unnecessary intraoperative cholangiography would be avoided in non-BA patients. CONCLUSIONS This scoring system accurately separates infants with BA and those with non-BA, rendering intraoperative cholangiography for confirming or excluding BA unnecessary in a substantial proportion of patients.

Abstract
BACKGROUND In developed countries, the outlook for patients with biliary atresia has improved remarkably owing to early referral, good diagnostic facilities and the availability of liver transplantation. In Nigeria and most of sub-Saharan Africa, there is little information on the current outlook for these children. METHODS A retrospective review of 14 patients with biliary atresia managed from 1991 to 2004 at Ahmadu Bello University Hospital, Zaria. RESULTS Six girls and eight boys presented at between 6 and 24 weeks of age (median 16). Seven presented to another hospital with persistent jaundice in the neonatal period. Eleven at presentation already had liver cirrhosis and deranged coagulation and could not have corrective surgery. Three patients aged 8, 10 and 16 weeks had Kasai's porto-enterostomy. Facilities for diagnosis were limited. Ten patients were lost to follow-up and their outcome is unknown. Of the three patients who had porto-enterostomy, one died at 2 years from gastro-enteritis, one from cholangitis after 8 weeks, and one did not recover from anaesthesia. One patient who had a laparotomy and liver biopsy died from peritonitis. CONCLUSION Owing to late presentation, delayed referral and difficulties in diagnosis, the outlook for infants with biliary atresia in this environment is poor. A concerted effort to encourage primary practitioners to detect and refer these infants at an earlier age is critical to outcome.

Abstract
Aims: To correlate the age at surgery, liver function tests, and hepatic and portal tract histo-pathological changes with surgical outcome in the form of disappearance of jaundice in extrahepatic biliary atresia (EHBA). Materials and Methods: This is a retrospective study of 39 cases of EHBA. There were 19 males and 10 females. Kasai's portoenterostomy (KPE) along with liver biopsy was performed in these patients; for purpose of correlation this biopsy was considered to be the preoperative biopsy. These patients were divided into three groups based upon surgical outcome: (A) disappearance of jaundice; (B) initial disappearance of jaundice with recurrence after 3 months; and (C) persistence of jaundice. Postoperatively, liver function tests and liver biopsies were repeated at 3 months after the KPE. Results: There were 11 patients in group A (28%), 21 patients in group B (54%), and seven patients in group C (18%). The age at surgery was comparable in all the three groups. The postoperative levels of serum bilirubin, alkaline phosphatase (ALP), and gamma glutamyl transpeptidase (GGTP) showed statistically significant improvement as compared with the preoperative levels in group A and B patients. Patients belonging to group C showed no improvement in the liver functions following surgery. The preoperative hepatic histopathological changes (hepatocellular alteration, cholestasis, bile ductular proliferation, and bile duct inflammation) showed a significant difference among the three groups; patients with lesser degrees of pre-existing histopathological changes had better outcome following surgery. Fibrosis was seen in all the three groups preoperatively but the difference was not statistically significant. Group C had significant fibrosis in more than 50% patients. Additional findings, viz. ductal plate malformation (9 patients, 23%) and giant cell transformation (19 patients, 49%) did not show any correlation with surgical outcomes. Conclusions: The liver function tests and the histopathological features appeared to affect the final surgical outcome of these patients. Higher degree of cholestasis, hepatocellular alteration, bile ductule proliferation, bile duct inflammation showed definite correlation with poor surgical outcome. High grade hepatic fibrosis and portal edema showed a trend towards poor outcome but did not achieve statistical significance.

Abstract
Biliary atresia is a rare neonatal disease of unknown etiology, where obstruction of the biliary tree causes severe cholestasis, leading to biliary cirrhosis and death in the first years of life, if the condition is left untreated. Biliary atresia is the most frequent surgical cause of cholestatic jaundice in neonates and should be evoked whenever this clinical sign is associated with pale stools and hepatomegaly. The treatment of biliary atresia is surgical and currently recommended as a sequence of, eventually, two interventions. During the first months of life a hepatoportoenterostomy (a "Kasai," modifications of which are discussed in this paper) should be performed, in order to restore the biliary flow to the intestine and lessen further damage to the liver. If this fails and/or the disease progresses towards biliary cirrhosis and life-threatening complications, then liver transplantation is indicated, for which biliary atresia represents the most frequent pediatric indication. Of importance, the earlier the Kasai is performed, the later a liver transplantation is usually needed. This warrants a great degree of awareness of biliary atresia, and the implementation of systematic screening for this life-threatening pathology.

Abstract
PURPOSE This study aimed to analyze the impact of age at Kasai operation on the short-term outcome of type III biliary atresia (BA) and to discuss if pathological scoring can be the prediction of effect in the Kasai procedure for the older (≥ 90 days) infant. METHODS During the period 2004 through 2010, 452 infants with type III BA were reviewed. The relationship between ages at Kasai operation and jaundice clearance rates and two year native liver survival rates were assessed, retrospectively. Pathological slides were analyzed with a histological scoring system. RESULTS All of the patients were divided into 3 groups according to their ages at operation (group A: aged 60 days or less (n=146), group B: age between 60 and 90 days (n=222) , and group C: age on or over 90 days (n=84)). The worst outcome of clearance of jaundice was found in group A but not in group C 2 weeks after the operation (P<0.05). Jaundice clearance rates showed no difference among the three groups either at 3-months or 6-months after operation. Moreover, in group C patients, the pathological scores showed no difference between the jaundice clearance group and jaundice persistence group 6 months after surgery. In group C, two year survival rate of patients with native livers was 36.1%. CONCLUSION Some patients over 90 days of age at surgery can still benefit from a Kasai procedure. The pathological scoring system does not play a role in predicting jaundice clearance in patients over 90 days of age at surgery.

Abstract
Introduction Biliary atresia (BA) is the most common cause of cholestatic jaundice in infancy. Early diagnosis and surgical management, ideally before 60 days of age, result in improved outcomes. We aimed to determine the age at diagnosis of BA in the Military Health System (MHS) and to compare the age at diagnosis by access to care models. We hypothesized that children with BA receiving primary care in military facilities have an earlier age at diagnosis due to decreased economic and access barriers. Methods Data for all Tricare enrollees born in fiscal years 2004–2008 with a diagnosis of BA were extracted from MHS databases. Non-parametric tests, Kaplan-Meier curves and log rank tests compared differences in age at diagnosis by type of primary care facility, gender, prematurity and presence of additional anomalies. Results 64 subjects were identified within the five year period. Median age at diagnosis was 40 days [range 1–189], with 67% diagnosed by 60 days and 80% by 90 days. 45 (70%) received civilian primary care within the MHS. There was no difference in the median age at diagnosis between subjects in the MHS with civilian primary care vs. military primary care (37 days [1–188] vs. 46 days [1–189]; p = 0.58). Conclusion In the MHS, two-thirds of infants with biliary atresia are diagnosed prior to 60 days of life. Gender, prematurity or presence of additional anomalies do not affect the timing of diagnosis. Civilian and military primary care models within the MHS make timely diagnoses of biliary atresia at equivalent rates.

Abstract
Biliary atresia is an infantile destructive inflammatory cholangiopathy that causes obliteration of both intrahepatic and extrahepatic bile ducts and eventually liver cirrhosis. So far, the exact etiology and pathogenesis of biliary atresia remain unclear, and possible etiologies include congenital and genetic factors, infection, inflammation, immune reaction, maternal factors, and vascular factors. Immunoinflammatory theory has been accepted by most researchers, which is supported by liver pathological changes. This review focuses on the recent progress in understanding pathogenesis and liver pathology in biliary atresia.

Abstract
BACKGROUND & AIMS Surgical treatment with Kasai portoenterostomy has improved the prognosis for patients with biliary atresia, although most patients ultimately require liver transplantation. Well-described patients with long-term, transplant-free survival are scarce; we assessed liver status and health perception among Dutch patients who survived 20 years after therapy and investigated whether the rate of transplant-free survival increases with time. METHODS By using the Dutch national database for biliary atresia, we identified 104 patients, born between 1977 and 1988. We collected data on clinical characteristics, liver biochemistry, and ultrasonography from all transplant-free patients who were alive at age 20 years (n = 28; 27% of the patients). General health perception data (RAND-36) were collected at the last examination. RESULTS The 20-year transplant-free survival rate increased from 20% (10 of 49) in the 1977 to 1982 cohort to 32% (18 of 55) in the 1983 to 1988 cohort (P = .03). Twenty-one percent of the long-term survivors (6 of 28) had normal liver biochemistry test results and no clinical or ultrasonographic signs of cirrhosis. The general health perception of female, but not male, patients, was lower, compared with controls (RAND-36 score, 54 ± 14 vs 74 ± 18; P = .005). CONCLUSIONS More than 25% of patients with biliary atresia survive at least 20 years without liver transplantation in The Netherlands. Women with biliary atresia have a reduced perception of their health, compared with control patients. Twenty percent of long-term survivors are symptom-free, without clinical or ultrasonographic signs of cirrhosis or portal hypertension.

Abstract
In order to further improve the outcome of BA, we characterized the mortality of BA patients who did not undergo OLT in the Netherlands, and compared our results with international data. For this purpose, we analyzed the causes of mortality of non-transplanted BA patients before the age of five yr, using the NeSBAR database. To evaluate trends in mortality, we compared the cohort 1987-1996 (n=99) with 1997-2008 (n=111). We compared clinical condition at OLT assessment with available international data, using the PELD-score. Mortality of non-transplanted BA children was 26% (26/99) in 1987-1996 and 16% (18/111) in 1997-2008 (p=0.09). Sepsis was the prevailing direct cause of death (30%; 13/44). PELD-scores at the time of assessment were higher in non-transplanted BA patients (median 20.5; range 13-40) compared with international data (mean/median between 11.7 and 13.3). Based on our national data, we conclude that pretransplant mortality of BA patients is still considerable, and that sepsis is a predominant contributor. Our results strongly indicate that the prognosis of patients with BA in the Netherlands can be improved by earlier listing of patients for OLT and by improving pretransplant care.

Abstract
PURPOSE To evaluate early postoperative results in a case controlled study following clinical use of stem cells in extrahepatic biliary atresia (EHBA). METHODS From July 2005 to March 2008, 30 cases of suspected EHBA were divided in two groups in an intervention study. Group A received autologous mononuclear bone marrow stem cells at the time of Kasai or after Kasai. In Group B, only Kasai was performed. Liver function tests on postoperative day 7 were compared. Serum bilirubin, clinical status, hepatic scintigraphy and survival at 6 months and 1 year were compared. RESULTS Mean age was 136 (74-275) days in Group A and 99.7 (56-172) days in Group B. Preoperative values of serum bilirubin (SB), aspartate aminotransferase (AST), alanine aminotransferase and alkaline phosphatase (ALP) were comparable between the groups though there was significant difference in postoperative SB, AST and ALP (p = 0.014, 0.0041, 0.0005), with and without the use of stem cells. The median post stem cell SB was 6.9 (0.5-11.6) mg/dl in Group A versus 10.1 (5.6-26.3) mg/dl in Group B. Median SB at 6 months follow-up was 0.6 (0.5-5.4) mg/dl in Group A versus 7.6 (0.8-9.2) mg/dl in Group B (p = 0.028). There was a significant difference in episodes of cholangitis at 6 months postoperatively between the two groups (p = 0.024). Hepatic scans done at <3 months; >3 months follow-up showed prompt excretion in 80% (4/5); 85.7% (6/7) in Group A versus 20% (1/5); 50% (1/2) in Group B. Survival at 6; 12 months' follow-up was 45.5%; 27.3% in Group A versus 33.3%; 6.7% in Group B. Median postoperative survival was 181 (139,223) days in Group A versus 123 (65,181) days in Group B. CONCLUSION Significant biochemical and scintigraphic improvement was noted following stem cell therapy in biliary atresia, probably attributable to anti-inflammatory action of stem cells.

Abstract
AIM This study aimed to determine the outcome of the operation of children with biliary atresia (BA) at a tertiary paediatric referral centre in Malaysia. METHODS A prospective study on all patients with BA referred to the University of Malaya Medical Centre (UMMC), Kuala Lumpur, from 1996 to 2005 was conducted. Survival with native liver, liver transplantation (LT) or death at 2 years of age was determined. RESULTS The median age at referral of the 57 patients with BA seen at University of Malaya Medical Centre was 62 days. Kasai procedure was not performed in nine patients who were all referred late (median age of referral 180 days). The median age at hepatoportoenterostomy (HPE) of the remaining 48 patients was 70 days. A total of 53 (93%) patients had type 3 BA, while only 1 (2%) patient had BA splenic malformation. At 2 years, the survival rate with native liver for the 48 patients who had HPE was 37%, while the overall survival (native liver and LT) rate was 40%. Two of the four patients who had LT survived with a liver graft at 2 years. CONCLUSIONS The 2-year survival with native liver following corrective surgery for BA in UMMC, Malaysia, compares favourably with other international figures, but the overall survival rate was adversely affected by a lack of timely LT. The outcome of BA in Malaysia may be further improved by increasing the awareness among child-health professionals on the importance early referral for appropriate surgery in infants suspected of having BA.

Abstract
BACKGROUND Increased age at surgery has a negative impact on results of the Kasai operation for biliary atresia in infancy and early childhood. It remained unclear if an age threshold exists and if this effect persists with extended follow-up. In this study we examined the relationship between increased age at surgery and its results in adolescence. METHODS All patients with biliary atresia who were living in France and born between 1986 and 2002 were included. Median follow-up in survivors was 7 years. RESULTS Included in the study were 743 patients with biliary atresia, 695 of whom underwent a Kasai operation; 2-, 5-, 10-, and 15-year survival rates with native liver were 57.1%, 37.9%, 32.4%, and 28.5%, respectively. Median age at Kasai operation was 60 days and was stable over the study period. Whatever the follow-up (2, 5, 10, or 15 years), survival rates with native liver decreased when age at surgery increased (< or =30, 31-45, 46-60, 61-75, and 76-90 days). Accordingly, we estimated that if every patient with biliary atresia underwent the Kasai operation before 46 days of age, 5.7% of all liver transplantations performed annually in France in patients younger than 16 years could be spared. CONCLUSIONS Increased age at surgery had a progressive and sustained deleterious effect on the results of the Kasai operation until adolescence. These findings indicate a rational basis for biliary atresia screening to reduce the need for liver transplantations in infancy and childhood.

BACKGROUND/PURPOSE In biliary atresia (BA), a derangement in the biliary system remains, despite portoenterostomy performance. Many factors can influence the disease progression rate. This study aimed to analyze the association between biliary proliferation extent in biopsies from BA patients and postoperative prognosis. METHODS Biliary proliferation was evaluated by a morphometric analysis of the cytokeratin 7 positivity percentage (PCK7) in wedge liver biopsies from 47 BA patients. The extent of fibrosis was evaluated by a fibrosis score (FS). The outcome 1-year native liver survival was correlated, using a multivariable regression analysis, with PCK7, FS, and age at portoenterostomy. RESULTS The PCK7 ranged between 0.80% and 14.79% (M +/- SD = 7.36% +/- 4.15%). Patients who died or underwent transplantation had higher PCK7 than survivors with their native livers (P < .001). The area under the receiver operating characteristic curve for PCK7 in relation to the outcome was 0.845 (P < .001). The cutoff point of PCK7 for the maximal effect on postoperative prognosis was 10.18% (sensitivity = 0.71, specificity = 0.88). The PCK7 was the only studied variable associated with 1-year native liver survival, independently of age and FS (P = .002). CONCLUSION The extent of biliary proliferation at portoenterostomy, evaluated by PCK7, was associated with 1-year native liver survival of BA patients.

Abstract
Extrahepatic biliary atresia (EHBA), an inflammatory sclerosing cholangiopathy, is the leading indication for liver transplantation in children. The cause is still unknown, although possible infectious, genetic, and immunologic etiologies have received much recent focus. These theories are often dependent on each other for secondary or coexisting mechanisms. Concern for EHBA is raised by a cholestatic infant, but the differential diagnosis is large and the path to diagnosis remains varied. Current treatment is surgical with an overall survival rate of approximately 90%. The goals of this article are to review the important clinical aspects of EHBA and to highlight some of the more recent scientific and clinical developments contributing to our understanding of this condition.
