Abstract
Background Outcomes in biliary atresia (BA) have been well-documented in large national cohorts from Europe, North America, and East Asia. Understanding the challenges that preclude success of the Kasai portoenterostomy (KPE) is the key to improve the overall outcomes of BA and implementing intervention strategies. Here, we analyzed the data from the Saudi national BA study (204 BA cases diagnosed between 2000 and 2018) to identify the prognostic factors of BA outcomes. Methods One hundred and forty-three cases underwent KPE. Several prognostic factors (center case load, congenital anomalies, serum gamma-glutamyl transferase, use of steroids, ascending cholangitis post-operatively, and degree of portal fibrosis at time of KPE) were investigated and correlated with the primary outcomes of interest: 1) success of KPE (clearance of jaundice and total serum bilirubin <20 mmol/l after KPE), 2) survival with native liver (SNL), and 3) overall survival. Results Use of steroids after KPE was associated with clearance of jaundice, 68% vs. 36.8% in the BA cases that did not receive steroids (P = 0.013; odds ratio 2.5) and a significantly better SNL rate at 2 - and 10-year of 62.22% and 57.77% vs. 39.47% and 31.57%, respectively (P = 0.01). A better 10-year SNL was observed in centers with caseload <1/year (group 1) as compared to centers that performed ≥1/year (group 2) [45.34% vs. 26.66%, respectively; P = 0.047]. On comparison of the 2 groups, cases in group 1 had KPE at significantly earlier age (median 59.5 vs. 75 days, P = 0.006) and received steroids after KPE more frequently than group 2 (69% vs. 31%, P < 0.001). None of the remaining prognostic variables were identified as being significantly related to BA outcome. Conclusion Steroids use post-KPE predicted clearance of jaundice and better short- and long-term SNL. There is a need to establish a national BA registry in Saudi Arabia aiming to standardize the pre- and post-operative clinical practices and facilitate clinical and basic research to evaluate factors that influence BA outcome.

Abstract
INTRODUCTION Biliary atresia is a rare obstructive cholangiopathy that presents in infants. The Kasai portoenterostomy procedure, which reestablishes biliary drainage into the intestine, is a surgical procedure that has been found to improve survival with the native liver. The options for postoperative analgesia include systemic opioids and epidural analgesia. The primary objective of this study was to compare the postoperative systemic opioids used in morphine equivalents (mg/kg) on postoperative days 0 through 3 between patients who underwent a Kasai portoenterostomy and received a thoracic epidural infusion to those without thoracic epidural analgesia. METHODS We conducted a retrospective cohort study of 91 infants with biliary atresia undergoing a Kasai portoenterostomy between January 1, 2009, and September 1, 2019, at the Children's Hospital of Philadelphia. RESULTS Sixty-three of the 91 patients (69%) had a continuous epidural catheter placed intraoperatively for postoperative analgesia. The total opioid requirement (morphine equivalents) for the first 72 h in the epidural group of (Mean (95% confidence interval): 0.52 mg/kg (0.38, 0.67 mg/kg) was lower than the non-epidural group (Mean (95% confidence interval): 1.15 mg/kg (0.8, 1.48 mg//kg) for a difference in mean opioid requirement (95% confidence interval) of 0.63 mg/kg (0.32, 0.94 mg/kg). Patients in the non-epidural group had higher rates of unplanned ICU admissions (36% non-epidural group vs. 3.3% epidural group, difference in proportion (95% confidence interval) 32.7% (13, 52%), p < .01). A higher percentage of patients in the non-epidural group had a postoperative oxygen requirement (32.1% vs. 11.3%, difference in proportion (95% confidence interval) 21% (2, 40%), p = .02). CONCLUSION In our cohort study, continuous thoracic epidural analgesia in patients undergoing a Kasai portoenterostomy was associated with lower postoperative opioid use. We also observed that the epidural group had a lower ICU admission rate and a lower rate of postoperative supplemental oxygen requirement over the first three postoperative days.

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).

Peri-Operative Liver Fibrosis and Native Liver Survival in Pediatric Patients with Biliary Atresia: A Systematic Review and Meta-Analysis. Pediatr Gastroenterol Hepatol Nutr 2022; 25:353-375. [PMID: 36148293 PMCID: PMC9482824 DOI: 10.5223/pghn.2022.25.5.353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 05/13/2022] [Accepted: 07/14/2022] [Indexed: 11/29/2022] Open
Abstract
No systematic review to date has examined histopathological parameters in relation to native liver survival in children who undergo the Kasai operation for biliary atresia (BA). A systematic review and meta-analysis is presented, comparing the frequency of native liver survival in peri-operative severe vs. non-severe liver fibrosis cases, in addition to other reported histopathology parameters. Records were sourced from MEDLINE, Embase, and CENTRAL databases. Studies followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and compared native liver survival frequencies in pediatric patients with evidence of severe vs. non-severe liver fibrosis, bile duct proliferation, cholestasis, lobular inflammation, portal inflammation, and giant cell transformation on peri-operative biopsies. The primary outcome was the frequency of native liver survival. A random effects meta-analysis was used. Twenty-eight observational studies were included, 1,171 pediatric patients with BA of whom 631 survived with their native liver. Lower odds of native liver survival in the severe liver fibrosis vs. non-severe liver fibrosis groups were reported (odds ratio [OR], 0.16; 95% confidence interval [CI], 0.08-0.33; I2 =46%). No difference in the odds of native liver survival in the severe bile duct destruction vs. non-severe bile duct destruction groups were reported (OR, 0.17; 95% CI, 0.00-63.63; I2 =96%). Lower odds of native liver survival were documented in the severe cholestasis vs. non-severe cholestasis (OR, 0.10; 95% CI, 0.01-0.73; I2 =80%) and severe lobular inflammation vs. non-severe lobular inflammation groups (OR, 0.02; 95% CI, 0.00-0.62; I2 =69%). There was no difference in the odds of native liver survival in the severe portal inflammation vs. non-severe portal inflammation groups (OR, 0.03; 95% CI, 0.00-3.22; I2 =86%) or between the severe giant cell transformation vs. non-severe giant cell transformation groups (OR, 0.15; 95% CI, 0.00-175.21; I2 =94%). The meta-analysis loosely suggests that the presence of severe liver fibrosis, cholestasis, and lobular inflammation are associated with lower odds of native liver survival in pediatric patients after Kasai.

Abstract
Interventional endoscopy can play a significant role in the care and management of children pre-and post- abdominal solid organ transplantation. Such procedures primarily include endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound (EUS), and balloon-assisted enteroscopy (BAE), though additional interventions are available using standard endoscopes (gastroscopes, colonoscopes) for therapeutics purposes such as endoscopic hemostasis. The availability of pediatric practitioners with the advanced training to effectively and safely perform these procedures are most often limited to large tertiary care pediatric centers. These centers possess the necessary resources and ancillary staff to provide the comprehensive multi-disciplinary care needed for these complex patients. In this review, we discuss the importance of interventional endoscopy in caring for transplant patients, during their clinical course preceding the potential need for solid organ transplantation and inclusion of a discussion related to endoscopic post-surgical complication management. Given the highly important role of interventional endoscopy in patients with recurrent and chronic pancreatitis, we also include a discussion related to this complex disease process leading up to those patients that may need pancreas surgery including total pancreatectomy with islet autotransplantation (TPIAT).

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 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
Biliary atresia (BA) is a progressive inflammation and fibrosis of the biliary tree characterized by the obstruction of bile flow, which results in liver failure, scarring and cirrhosis. This study aimed to explore the elusive aetiology of BA by conducting whole exome sequencing for 41 children with BA and their parents (35 trios, including 1 family with 2 BA-diagnosed children and 5 child-mother cases). We exclusively identified and validated a total of 28 variants (17 X-linked, 6 de novo and 5 homozygous) in 25 candidate genes from our BA cohort. These variants were among the 10% most deleterious and had a low minor allele frequency against the employed databases: Kinh Vietnamese (KHV), GnomAD and 1000 Genome Project. Interestingly, AMER1, INVS and OCRL variants were found in unrelated probands and were first reported in a BA cohort. Liver specimens and blood samples showed identical variants, suggesting that somatic variants were unlikely to occur during morphogenesis. Consistent with earlier attempts, this study implicated genetic heterogeneity and non-Mendelian inheritance of BA.

Abstract
OBJECTIVE Three criteria (age at first pale stool, age at portoenterostomy, and duration from the first pale stool to portoenterostomy) were assessed for prognostic value in biliary atresia. METHODS The medical records of 116 consecutive biliary atresia patients treated by portoenterostomy after liver transplantation became available in Japan in 1989 were identified and data from 96 were analyzed retrospectively for this study. The impact of each criterion on clearance of jaundice to normal levels (total serum bilirubin ≤1.2 mg/dL) and survival with the native liver as indicators of outcome were compared according to time (≤30 days, 31-60 days, and ≥61 days). RESULTS Age at first pale stool was ≤30 days in 53, 31-60 days in 26, ≥61 days in 17; age at portoenterostomy was ≤30 days in 7, 31-60 days in 35, ≥61 days in 54, and duration pre-portoenterostomy was ≤30 days in 50, 31-60 days in 36, ≥61 days in 10. Survival with the native liver was not significantly influenced by age at first pale stool or age at portoenterostomy, but prolonged duration (≥61 days) reduced survival with the native liver significantly (p = 0.003). Clearance of jaundice to normal levels was not affected by any criterion at any time.

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
AIM This study compared the outcomes of patients with biliary atresia (BA) treated according to a standardised protocol with historical patients. METHODS This is a single-centred retrospective study of BA patients treated from 1980 to 2016. A standardised treatment protocol was established since 2008 regarding peri-operative management. The outcomes being compared between the two groups (Groups I and II = before and after 2008, respectively) were jaundice clearance (JC), incidence of recurrent cholangitis, hospital admission and native liver survival (NLS). RESULTS A total of 128 patients were included (Group I = 100, Group II = 28). The overall median follow-up period was 15.3 years (I vs. II = 20.6 years vs. 5.1 years, respectively). There was no significant difference in the JC at the sixth month between the two groups (I vs. II = 60.0 vs. 82.1%, respectively, P = 0.07). The incidence of recurrent cholangitis was similar between the two groups (I vs. II = 39 vs. 35.7%, respectively, P = 0.45), but the median hospital admission episode per patient was non-significantly higher in Group I (I vs. II = 4.2 vs. 2.7, respectively, P = 0.08). There was an improvement in the 1-year NLS rate in Group II (I vs. II = 69.0 vs. 85.7%, respectively, P = 0.05). CONCLUSIONS The introduction of a standardised management protocol has improved the short-term outcome of BA patients, with a better 1-year NLS observed.

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 Kasai procedure is the standard initial treatment of infants with biliary atresia. The key to perform a successful surgery is to accurately remove the fibrous portal plate near the liver hilum. Yet how to estimate surgical difficulty pre-operatively remains unclear. This study aims to design an algorithm that predicts the difficulty of Kasai procedure using liver stiffness measurement (LSM). Methods One hundred ninety-nine patients were included from April 2012 to December 2016. The patients were all surgically diagnosed with biliary atresia. Group A comprised of patients with porta hepatis retraction (the angle between the plane of the fibrous porta plate and the plane of the medial liver closest to the plate was equal to or smaller than 90°), group B comprised of patients without porta hepatis retraction (the angle between the plane of the fibrous porta plate and the plane of the medial liver closest to the plate was greater than 90°). Liver function measurements and LSM were measured for all patients within three days before surgery. Results Our study included 19 cases in group A (9 males, 10 females) and 180 cases in group B (87 males, 93 females). LSM had statistical differences between the two groups, 28.10(14.90) kPa VS 10.89(7.10) kPa, P = 0.000. There was a significant relationship between LSM and operative age, TBA, AST, GGT (P = 0.000, 0.003, 0.003, 0.012, correlation coefficient = 0.323, 0.213, 0.207, 0.179). The AUROC of LSM was 0.919. When the cutoff value was 15.15 kPa(OR = 3.989; P = 0.000), the sensitivity, specificity, PPV, NPV and diagnostic accuracy were 0.947, 0.750, 0.285, 0.992 and 0.768, respectively. When the value was 23.75 kPa(OR = 3.483; P = 0.000), the sensitivity, specificity, PPV, NPV and diagnostic accuracy were 0.631, 0.950, 0.571, 0.960 and 0.919, respectively. Conclusions LSM can be used to predict the difficulty in dissecting fibrous portal plate, and in turn, the difficulty of Kasai procedure. LSM > 23.75 kPa suggests a more complicated surgery.

Inflammation, Active Fibroplasia, and End-stage Fibrosis in 172 Biliary Atresia Remnants Correlate Poorly With Age at Kasai Portoenterostomy, Visceral Heterotaxy, and Outcome.

Abstract
Published histologic studies of the hilar plate or entire biliary remnant at the time of Kasai portoenterostomy (KHPE) have not provided deep insight into the pathogenesis of biliary atresia, relation to age at surgery, prognosis or the basis for successful drainage. We report detailed histologic findings in 172 centrally reviewed biliary remnants with an average of 6 sections per subject. Active lesions were classified as either necroinflammatory (rare/clustered in a few subjects) or active concentric fibroplasia with or without inflammation (common). Inactive lesions showed bland replacement by collagen and fibrous cords with little or no inflammation. Heterogeneity was common within a given remnant; however, relatively homogenous histologic patterns, defined as 3 or more inactive or active levels in the hepatic ducts levels, characterized most remnants. Homogeneity did not correlate with age at KHPE, presence/absence of congenital anomalies at laparotomy indicative of heterotaxy and outcome. Remnants from youngest subjects were more likely than older subjects to be homogenously inactive suggesting significantly earlier onset in the youngest subset. Conversely remnants from the oldest subjects were often homogenously active suggesting later onset or slower progression. More data are needed in remnants from subjects <30 days old at KHPE and in those with visceral anomalies. Prevalence of partially preserved epithelium in active fibroplastic biliary atresia lesions at all ages suggests that epithelial regression or injury may not be a primary event or that reepithelialization is already underway at the time of KHPE. We hypothesize that outcome after KHPE results from competition between active fibroplasia and reepithelialization of retained, collapsed but not obliterated lumens. The driver of active fibroplasia is unknown.

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 Biliary atresia represents the most common surgically treatable cause of cholestasis in newborns. If not corrected, secondary biliary cirrhosis invariably results. OBJECTIVE To evaluate, through multivariate analysis, the prognostic factors associated with the presence of biliary flow and survival with the native liver following Kasai portoenterostomy. METHODS The study analyzed data from 117 biliary atresia patients who underwent portoenterostomy and had suitable histological material for evaluation. A logistic regression model was used to assess the presence of biliary flow. Survival was investigated through Kaplan-Meier curves and Cox-adjusted models. RESULTS One third of patients achieved biliary flow and the median age at surgery was 81 days. Age at surgery, albumin, postoperative complications, biliary atresia structural malformation (BASM), liver architecture, larger duct diameter at porta hepatis, and cirrhosis (Ishak score) were the initial variables for the multivariate analysis. Age at surgery >90 days was the only variable associated with the absence of biliary drainage. Survival analysis revealed that the absence of biliary flow (P<0.0001), age at surgery >90 days (P=0.035), and the presence of BASM (P<0.0001), alone, could predict death or need for liver transplantation. Multivariate analysis demonstrated that the absence of biliary flow (P<0.0001 hazard ratio [HR] 6.25, 95% confidence interval [CI] 3.19-12.22) and the presence of BASM (P=0.014 HR 2.16, 95% CI 1.17-3.99) were associated with lowest survival with the native liver. CONCLUSION Age at surgery >90 days was associated with absence of biliary flow. The presence of biliary drainage and the absence of structural malformations are cornerstone features for higher survival rates with the native liver.

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
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
Biliary atresia (BA) results in severe bile blockage and is caused by the absence of extrahepatic ducts. Even after successful hepatic portoenterostomy, a considerable number of patients are likely to show progressive deterioration in liver function. Recent studies show that mutations in protein-coding mitochondrial DNA (mtDNA) genes and/or mitochondrial genes in nuclear DNA (nDNA) are associated with hepatocellular dysfunction. This observation led us to investigate whether hepatic dysfunctions in BA is genetically associated with mtDNA mutations. We sequenced the mtDNA protein-coding genes in 14 liver specimens from 14 patients with BA and 5 liver specimens from 5 patients with choledochal cyst using next-generation sequencing. We found 34 common non-synonymous variations in mtDNA protein-coding genes in all patients examined. A systematic 3D structural analysis revealed the presence of several single nucleotide polymorphism-like mutations in critical regions of complexes I to V, that are involved in subunit assembly, proton-pumping activity, and/or supercomplex formation. The parameters of chronic hepatic injury and liver dysfunction in BA patients were also significantly correlated with the extent of hepatic failure, suggesting that the mtDNA mutations may aggravate hepatopathy. Therefore, mitochondrial mutations may underlie the pathological mechanisms associated with BA.

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
Paediatric hepatology dates from the 1970s and it is the youngest of the organ-specific subspecialties. As then there have been impressive achievements in the fields of anatomical, metabolic, immunological and neoplastic diseases, and the advent of modern molecular biology has resulted in a marked increase in exact diagnoses. Liver transplants provided enormous stimulus for the discipline. Due to changing morbidity patterns, the discipline faces new challenges, such as environment- and lifestyle-induced liver diseases, but different forms of chronic viral hepatitis are diminishing. CONCLUSION High levels of competence require good clinical research, optimal results and a high degree of centralisation.

Abstract
Due to a peculiar age-dependent increased susceptibility, neonatal cholestasis affects the liver of approximately 1 in every 2500 term infants. A high index of suspicion is the key to an early diagnosis, and to implement timely, often life-saving treatments. Even when specific treatment is not available or curative, prompt medical management and optimization of nutrition are of paramount importance to survival and avoidance of complications. Areas covered: The present article will prominently focus on a series of newer diagnostic and therapeutic options of cholestasis in neonates and infants blended with consolidated established paradigms. The overview of strategies for the management reported here is based on a systematic literature search published in English using accessible databases (PubMed, MEDLINE) with the keywords biliary atresia, choleretics and neonatal cholestasis. References lists from retrieved articles were also reviewed. Expert commentary: A large number of uncommon and rare hepatobiliary disorders may present with cholestasis during the neonatal and infantile period. Potentially life-saving disease-specific pharmacological and surgical therapeutic approaches are currently available. Advances in hepatobiliary transport mechanisms have started clarifying fundamental aspects of inherited and acquired cholestasis, laying the foundation for the development of possibly more effective specific therapies.

Abstract
OBJECTIVES To evaluate the diagnostic performance of sonographic features of biliary atresia in patients with infantile cholestasis. METHODS The Ovid-MEDLINE and EMBASE databases were searched for studies of the diagnostic performance of sonographic features of biliary atresia in patients with infantile cholestasis. A meta-analysis was performed to evaluate the diagnostic performance of the triangular cord sign and other sonographic features in patients with biliary atresia. RESULTS Seventeen eligible studies with 1444 patients were included. The triangular cord sign had high accuracy for diagnosing biliary atresia: the meta-analytic summary sensitivity and specificity were 85% (95% confidence interval, 77%-90%) and 97% (95% confidence interval, 94%-99%), respectively. The area under the hierarchical summary receiver operating characteristic curve was 0.97. Meta-regression analysis revealed that the cutoff thickness of the triangular cord sign (3 or 4 mm) was a significant factor affecting study heterogeneity (P < .01). The proportions of nonidentification of the gallbladder (GB) ranged from 0% to 53%. Abnormal GB morphologic characteristics, nonvisualization of the common bile duct, and the presence of hepatic subcapsular flow showed relatively high sensitivities and specificities. CONCLUSIONS The triangular cord sign and other sonographic features, including abnormal GB morphologic characteristics, nonvisualization of the common bile duct, and the presence of hepatic subcapsular flow, had high diagnostic performance for the diagnosis of biliary atresia.

Abstract
OBJECTIVES The purpose of this study was to investigate the diagnostic performance of acoustic radiation force impulse (ARFI) in assessing liver fibrosis preoperatively in infants with biliary atresia (BA). METHODS A total of 50 consecutive infants with BA and 50 healthy infants who underwent ARFI examination were recruited. Siemens Acuson S2000 in Virtual Touch Quantification mode (Siemens Medical Solutions, Mountain View, CA) was used to measure shear wave speeds (SWSs). All infants with BA underwent a liver biopsy within 3 days after ARFI imaging. The liver fibrosis stages of specimens were defined according to the Batts-Ludwig scoring system. The correlation analysis was performed between SWSs and pathological findings. Cut-off values were determined using receiver operating characteristic (ROC) curves. RESULTS The mean SWS in the BA group was significantly higher than controls (mean ± standard deviation): 1.89 ± 0.45 versus 1.12 ± 0.06 m/s; P < .001). A significant correlation was found between the SWSs and fibrosis stages (r = 0.719, P < .001). The cut-off value for predicting significant fibrosis (F ≥ 2), severe fibrosis (F ≥ 3), and cirrhosis (F = 4) was 1.53, 1.80 and 2.16 m/s, respectively, and the area under the ROC curve was 0.823, 0.884 and 0.917, respectively. CONCLUSIONS Acoustic radiation force impulse imaging showed significant correlation with the severity of liver fibrosis by comparing it with liver fibrosis biopsy pathology. It may be an effective method for liver fibrosis assessment, prognosis prediction, and clinical management in infants with BA.

Abstract
This study aimed to analyze the impact of etiologic heterogeneity and operation age on prognosis of infants with biliary atresia (BA) who received Kasai operation prior to 60 days of age.From 2004 to 2010, 158 infants received Kasai operation before turning 60 days old. According to Davenport 2012 classifications, 4 groups of BA were defined: cystic BA, syndrome BA, and associated malformation, cytomegalovirus (CMV)-associated BA, and isolated BA. Native (autologous) liver survival rates and incidence of cholangitis 2 years after operation, as well as jaundice clearance rates 3 months after operation, were recorded.Although infants who received the operation between 51 and 60 days of age had a better jaundice clearance 3 months after operation and lower incidence of cholangitis as compared with those under 40 or between 41 and 50 days of age, there was no significant difference in survival rates. Among types of BA, infants with cystic BA had the best prognosis. In the syndrome BA and associated malformations group, as well as CMV-associated group, infants who received the operation early (<40 days of age) had a worse outcome as compared with those who received the operation between 41 and 50 days or 51 and 60 days of age.Both clinical etiologic heterogeneity and operation age may influence BA prognosis.

Abstract
PURPOSE OF REVIEW Biliary atresia is the most common indication for liver transplantation among children. In recent years, prospective, multi-centre collaboration has been underway with the aim of providing high-quality data on the natural history of the condition, prior to and following hepatic portoenterostomy. RECENT FINDINGS There is increasing evidence that specific histological findings, and age, at the time of portoenterostomy have relevance as prognostic indicators. Recent data suggest that the sub-type of biliary atresia, its co-existence with other anomalies and concurrent infection may also be important variables. This review provides a comprehensive summary of the histological predictors of outcome following portoenterostomy. Later age at portoenterostomy, advanced degree of hepatic fibrosis and co-existence with other congenital anomalies are strongly correlated with poor outcomes following portoenterostomy. There is increasing evidence to suggest that common serological indices and the presence or absence of cytomegalovirus (CMV) co-infection may have utility as early prognostic indicators.

Abstract
UNLABELLED Jaundice and pale stools are major indicators of neonatal liver disease. Prognosis depends on timely diagnosis and management. We evaluated the clinical practices among healthcare professionals concerning jaundiced newborns and their ability to recognize pale stools. We supplied a questionnaire and a panel with eight photographs of stools, both locally validated, to physicians and nurses of the National Healthcare Service. Analysis was conducted according to professional status, specialization and years of experience of professionals and level of healthcare. Questionnaires were administered to 266 participants (100 physicians, 166 nurses). The decision to send patients to medical observation depended on the intensity of jaundice for a significant percentage of nurses. Concerning jaundiced newborns breastfed and otherwise healthy, 28.9% of physicians would never request a conjugated bilirubin assay, and only 43.3% would request it after 14 days old; for those with other signs/symptoms of disease, only 69.1% of physicians would request it immediately. Multiple linear regression analysis identified specialization as an independent variable significantly associated with the ability to recognize pale stools. CONCLUSION A significant percentage of healthcare professionals assumed clinical practices that preclude the timely recognition of cholestasis/pale stools, reinforcing the idea of educational needs. Specialization, rather than years of experience of professionals, was associated with better skills and practices. What is Known: • Neonatal cholestasis is a condition with some rare underlying entities having high mortality and morbidity. Early diagnosis is crucial to improve prognosis. Yet, many cases remain late recognized and referred. • Studies evaluating the ability of healthcare professionals to recognize neonatal cholestasis are scarce. What is New: • In this study, a significant percentage of professionals assumed clinical practices that preclude timely recognition of neonatal cholestasis and pale stools, reinforcing the idea of educational needs. • Specialization of professionals was associated with better skills and practices.

Abstract
Cholestatic jaundice in infancy affects approximately 1 in every 2500 term infants and is infrequently recognized by primary providers in the setting of physiologic jaundice. Cholestatic jaundice is always pathologic and indicates hepatobiliary dysfunction. Early detection by the primary care physician and timely referrals to the pediatric gastroenterologist/hepatologist are important contributors to optimal treatment and prognosis. The most common causes of cholestatic jaundice in the first months of life are biliary atresia (25%-40%) followed by an expanding list of monogenic disorders (25%), along with many unknown or multifactorial (eg, parenteral nutrition-related) causes, each of which may have time-sensitive and distinct treatment plans. Thus, these guidelines can have an essential role for the evaluation of neonatal cholestasis to optimize care. The recommendations from this clinical practice guideline are based upon review and analysis of published literature and the combined experience of the authors. The committee recommends that any infant noted to be jaundiced after 2 weeks of age be evaluated for cholestasis with measurement of total and direct serum bilirubin, and that an elevated serum direct bilirubin level (direct bilirubin levels >1.0 mg/dL or >17 μmol/L) warrants timely consideration for evaluation and referral to a pediatric gastroenterologist or hepatologist. Of note, current differential diagnostic plans now incorporate consideration of modern broad-based next-generation DNA sequencing technologies in the proper clinical context. These recommendations are a general guideline and are not intended as a substitute for clinical judgment or as a protocol for the care of all infants with cholestasis. Broad implementation of these recommendations is expected to reduce the time to the diagnosis of pediatric liver diseases, including biliary atresia, leading to improved outcomes.

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
INTRODUCTION Extrahepatic biliary atresia is a progressive disorder characterised by fibroinflammatory obliteration or stenosis of the extrahepatic biliary tree leading to obstruction of bile flow and cholestatic jaundice. It is the most common cause for cholestasis in newborn. Histopathological criteria for diagnosing biliary atresia from liver biopsy have not been clearly defined. AIM This study was undertaken to analyse the significance of the various histopathological features in diagnosis and prognosis of extrahepatic biliary atresia from liver biopsy specimens. MATERIALS AND METHODS This was a retrospective study of 43 cases of extra-hepatic biliary atresia diagnosed and treated at a tertiary care hospital between January 2010 to December 2014. Formalin fixed paraffin embedded liver biopsy tissues were processed by standard technique and the slides were stained with haematoxylin and eosin. All the slides were reviewed and graded by a semi-quantitative scoring system. Features such as increased age at kasai's portoenterostomy, portal fibrosis, bile duct proliferation, cholestasis, portal inflammation and duct plate malformation were studied. Statistical analysis was worked out using SPSS 17.0 (statistical package for the social science software). Chi-square test was used to find association between various parameters with respect to mortality and Kaplan-Meier estimator was used for survival analysis of the population under study. RESULTS In this study comprising of 43 cases, only 6 cases (13.95%) were alive at the end of 6 months follow-up. Twenty patients who died and the 17 cases with poor survival had greater degrees of fibrosis, bile duct proliferation and cholestasis. Majority of the cases with duct plate malformation expired inspite of earlier surgical intervention. Thus proving the association of fibrosis, bile duct proliferation, cholestasis and duct plate malformation with the survival and prognosis of biliary atresia cases. Age at surgery did not show any correlation with prognosis as cases operated even at <60 days had poor survival. CONCLUSION From this study it can be concluded that in extrahepatic biliary atresia patients, presence of duct plate malformation, greater degrees of fibrosis, bile duct proliferation and cholestasis were strongly associated with poor prognosis.

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 In extrahepatic biliary atresia (EHBA) obstruction of the biliary tree causes severe cholestasis leading to cirrhosis and death if left untreated in a timely manner. Infants with cholestasis may undergo many tests before EHBA diagnosis is reached. The role and place of preoperative liver biopsy in the diagnostic paradigm for EHBA have not been established. METHODS We conducted a systematic review of MEDLINE, Embase, and CENTRAL to obtain all publications describing the sensitivity/specificity/accuracy/positive predictive value (PPV)/negative predictive value (NPV) of preoperative liver biopsy in infants with cholestasis. Screening, data extraction, and quality assessment were done in duplicate. Extracted data are described narratively and analyzed using forest plots and receiver operating characteristic curves. RESULTS A total of 22 articles were included. Overall, the pooled accuracy of preoperative liver biopsy was 91.7%, with a sensitivity of 91.2%, specificity of 93.0% (n=1231), PPV of 91.2%, NPV of 92.5% (n=1182), and accuracy of 91.6% (n=1106). In patients who were 60days or less at time of presentation or diagnosis, the pooled sensitivity, specificity, PPV, NPV, and accuracy were 96.4%, 96.3%, 95.8%, 96.3%, and 94.9%, respectively. CONCLUSION Quantitative analysis demonstrated preoperative biopsy to be both highly specific and sensitive in diagnosing EHBA preoperatively. It is a highly reliable test that offers a means of arriving at an early definitive diagnosis of EHBA.

Abstract
Aims: In 1955, Professor Morio Kasai first performed a hepatic portoenterostomy. Since then, the procedure has changed the lives of children with biliary atresia (BA). We report our initial experience in performing “extended” Kasai portoenterostomy (KPE), a modification of the original procedure. Materials and Methods: Since 2013, we have used the technique of “extended KPE” and prospectively recorded data on all children undergoing this operation. Data on demographics, clinical features, liver function tests, and perioperative cholangiogram findings were collected. Outcome of KPE was measured by Jaundice Disappearance Rate (JDR) and Native Liver Survival Rate (NLSR). We present our preliminary results from a 30-month period (February 2013 to May 2015). Results: Thirty-one children underwent KPE during this period (19 males) and only 1 child had biliary atresia splenic malformation (BASM). The mean age at KPE was 73 ± 24 days. Five (16.1%) children were more than 90 days old at the time of KPE. Fourteen children cleared jaundice (JDR 45.2%). Eleven (35.5%) children developed episodes of cholangitis, of whom 8 had early cholangitis (within 3 months of the operation). The proportion of children who survived with their own liver 6 months after KPE (NLSR) was 84.2%. Of those children older than 90 days, 2 cleared jaundice and have survived with their native livers for more than 16 months. Conclusion: In our preliminary report of 31 children, we conclude that the extended KPE leads to increased jaundice clearance and improved NLSR in children with BA.

Abstract
OBJECTIVE The purpose of this study was to evaluate the diagnostic and prognostic value of a histological scoring system in biliary atresia (BA). METHODS From June 2013 to July 2014, 86 wedge liver biopsy specimens were obtained from infants with neonatal cholestasis (58 patients with biliary atresia and 28 patients with non-obstructive cholestasis as control) in our center. A pathologist, single-blinded to the final diagnosis, made the histological diagnosis individually based on an 8-feature (liver fibrosis, portal ductal proliferation, bile plugs in portal ductules, cholestasis, hepatocellular changes inflammatory cells infiltration in portal region, extramedullary hematopoiesis, and ductal plate malformation), 21-point (0 to 21) scoring system. RESULTS In this retrospective study, ductular reaction (bile ductular proliferation) and liver fibrosis in the portal area, bile plugs, and ductal plate malformation were the best indicators of BA. With the scoring system, a score of ≥8 had the best diagnostic utility to differentiate BA from other intrahepatic cholestasis histologically (sensitivity 94.7%, specificity 86.2%, accuracy 91.9%). Liver fibrosis and ductal plate malformation were confirmed to be related with the prognosis. CONCLUSIONS An 8-feature, 21-point histological scoring system has a good diagnostic accuracy in the interpretation of liver histology in neonatal cholestasis. The use of liver fibrosis and ductal plate malformation are also feasible to assess the prognosis.

Abstract
The aim of this study was to investigate whether an artificial bile duct made of bioabsorbable polymer could serve as a substitute for narrowed portions of the bile duct. The experiments were performed using hybrid pigs (n = 11). After laparotomy under general anesthesia, the extrahepatic bile duct was identified and ligated around the confluence with the cystic duct. A week later, repeat laparotomy was performed on the animals, and the bile duct on the hepatic side of the ligature was resected. The cut end was connected to the duodenum using a bioabsorbable artificial bile duct fabricated from a copolymer of polycaprolactone and polylactic acid fibers. The grafts were recovered for gross, histologic, and blood chemical studies at 4 months after the surgery. All recipient pigs survived until they were humanely killed for collection of the implants. A week of ligation of the extrahepatic bile duct dilated the duct to approximately 1 cm in diameter and increased total bilirubin. Total bilirubin had returned to the pre-implantation level in all animals at 4 months post implantation. Examinations of the grafts revealed complete freedom of stricture and the regeneration of a neo-bile duct of approximately 1 cm in diameter from the graft site in 10 of 11 animals. Gross observation of the graft from the 1 remaining animal revealed stricture at the anastomosis site and poor bile duct epithelization. We have concluded that this bioabsorbable polymer bile duct can serve as a replacement for narrowed portions of the bile duct.

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
AIM OF THE STUDY The outcome of Kasai operation is not uniformly successful. This objective of this study is to identify risk factors that predict early failure of this operation. METHODS A retrospective study was carried out for all patients who received Kasai operation between 1980 and 2012. Patients referred from other centers for liver transplantation because of failed Kasai operation were also recruited. MAIN RESULTS A total of 185 patients were reviewed. A total of 119 (64.3%) patients failed Kasai operation, whereas 86 (46.5%) were considered as cases of early failure (<3 years post-Kasai). With univariate analysis, the presence of associated anomaly (RR: 1.90, 95%CI 1:45-2:36), operation with laparoscopic surgery (RR: 3.14, 95% CI: 2.39-5.42), delayed clearance of jaundice (RR: 1.89, 95% CI: 1.56-2.67), and repeated cholangitis (RR: 2.56, 95% CI: 1.39-3.42) were associated with adverse outcome, whereas the use of adjuvant steroid at post-operative period appeared to be protective (RR: 0.64, 95% CI: 0.29-0.93). With multivariate analysis, repeated cholangitis was an independent risk factor for early failure after Kasai operation (RR: 3.16, 95% CI: 1.83-4.62). Furthermore, it was also considered as a risk factor for failure after 3 year post-Kasai (RR: 2.07, 95% CI: 1.43-3.42). CONCLUSION Patients with above risk factors are prone to fail Kasai operation in an early stage and require more frequent monitoring. Prevention and aggressive management of cholangitis should be considered as measures to avoid disease progression in the early stage. Lastly, performing open Kasai operation and the use of adjuvant steroid are potentially beneficial.

Abstract
CONTEXT Biliary atresia is a progressive, idiopathic, fibro-obliterative disease of the extrahepatic biliary tree that presents with biliary obstruction exclusively in the neonatal period. OBJECTIVES To assess the differences regarding age at referral, age at surgery, duration of propaedeutics and waiting time for surgery between two groups of infants in different periods. METHODS Retrospective study of infants diagnosed with biliary atresia on two periods: 1983-1993 and 1998-2011. RESULTS Biliary atresia was diagnosed in 129 infants, being 48 in casuistic I and 81 in casuistic II. The median age at admission was 94 and 60 days, respectively (P = 0.0001). On evaluating patients who had undergone portoenterostomy before 120 days of age, no difference was observed regarding the duration of propaedeutics or waiting time for surgery (P = 0.15), but difference was found when comparing the age at surgery (P = 0.002). Among those infants with no biliary flow and without liver transplantation or death after 18 post-operative months, the estimated probability of survival was 44.6% and 38.7% in casuistics I and II, respectively. In casuistic I, all infants who showed biliary flow were alive during the observation period and, in casuistic II, 80.3% were alive after 7 years of follow-up. CONCLUSIONS Even though patients were admitted and treated earlier, it is clear that surgery could be done sooner. Delay in referral and timely propaedeutics were the main contributors.

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
OBJECTIVE To study the use of fine needle aspiration (FNA) cytology in neonatal biliary atresia (BA). METHODS Twelve female and nine male patients (age range, 3-7 months; mean age, 4.5 months) with a pre-operative diagnosis of BA, who were scheduled for Kasia portoenterostomy and selected for intraoperative FNA, were studied. RESULTS Cholestasis, bile deposits, bile infarcts, hepatitic rosettes enclosing bile plugs, feathery degeneration of hepatocytes and inflammatory cells were seen in the cytological slides. Bile infarcts, rosette formation and inflammatory cells were mainly noticed in type 3 BA. Bile infarcts and hepatitic rosettes are surrogate findings for the diagnosis of the obstructive type of cholestasis. CONCLUSION With the help of imaging studies, FNA in a multidisciplinary setting can be diagnostic of neonatal BA when cytological features suggest the obstructive nature of cholestasis, but this procedure cannot replace completely liver biopsy for this diagnosis.

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
OBJECTIVES To investigate the characteristics of biliary atresia (BA) in preterm infants. STUDY DESIGN Nationwide screening for BA in Taiwan using an infant stool color card was launched in 2004. We investigated the characteristics of BA in preterm infants using the national stool card registry center database. RESULTS We identified 197 cases of BA from January 2004 to June 2010. The overall incidence of BA was 1.51 cases per 10,000 live births. The annual incidence of BA per 10,000 live births in term and preterm infants was 1.43 and 2.37 (P < .05), respectively. The sensitivity of detecting BA using stool cards before 60 days of age was 92.8% in term, and 96.3% in preterm infants. The Kasai operation before 60 days of age was 68.7% in term, and 44.4% in preterm infants. The jaundice-free rate at 3 months after the Kasai operation among infants with BA was 62.0% in term, and 37.0% in preterm infants (P = .015). The 18-month survival rate with native liver was higher in the term infants (72.7%) than that in the preterm infants (50.0%) (P = .043). CONCLUSION The incidence of BA in preterm infants is more frequent than in term infants. The stool color card is sensitive to detecting BA in preterm infants. Preterm infants with BA were more prone to delayed Kasai operation and had poorer outcome.
