Abstract
For patients with Biliary atresia, antibiotic prophylaxis after Kasai portoenterostomy is a common practice. Societal guidelines often cite one reference as supportive evidence for this practice. In this paper, we go back to review the quality of this evidence and suggest more research is required to demonstrate the efficacy of antibiotic prophylaxis in this population.

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.

J Indian Assoc Pediatr Surg 2024; 29:271-276. [PMID: 38912031 PMCID: PMC11192269 DOI: 10.4103/jiaps.jiaps_250_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 01/29/2024] [Accepted: 02/05/2024] [Indexed: 06/25/2024] Open
Abstract
Background Extrahepatic biliary atresia (BA) is seen in infants, with an incidence of 1 in 15,000 live births. The presentation is progressive jaundice, dark-colored urine, and clay-colored stools. Kasai portoenterostomy (KPE) is the commonly performed surgical procedure in these patients. Postoperatively, phenobarbitone, ursodeoxycholic acid (UDCA), steroids, and other drugs are given to improve bile drainage and prevent inflammation and fibrosis. However, a definitive protocol regarding the need for different drugs, dosage, and duration varies across individual surgeons and centers. No universally accepted protocol exists for postoperative management after KPE. Aim The aim of this study was to know the prevailing postoperative management of BA by subject experts and use the Delphi process to know if the experts want to change their practice based on the results from the survey. Material and Methods A questionnaire was made after discussing with two experts in the field of BA. The questionnaire was mailed to 25 subject experts. The first survey data were analyzed and shared with all responders. In the second survey, change in the management based on the results from the first survey was assessed. Results The Delphi questionnaire was answered by 17 experts. Postoperatively, prophylactic antibiotics are prescribed for 6-12 weeks by around 40% and >12 weeks by 30% of respondents. Phenobarbitone is prescribed for <3 months by nearly 50%. UDCA is prescribed for <3 months, ≤6 months, and 6 months-1 year by 47.1%, 23.5%, and 23.5% responders, respectively. Nearly 50% prescribe steroids (mostly prednisolone), and among them, two-thirds prescribe it for 6-12 weeks. Approximately 60% give antiviral drugs to children who are cytomegalovirus immunoglobulin M positive. In our survey, 50% of experts perform 5-10 KPE per year, and 25% each perform 10-15 and >15 KPE per year. The second survey noted that a significant percentage of responders want to change their practice according to consensus. Conclusion From our Delphi survey, an overview of the postoperative management of BA could be made. However, multicentric studies are required for uniform protocol on the postoperative management of BA.

Abstract
Introduction The diagnosis of biliary atresia (BA) remains challenging, and there is still uncertainty regarding the optimal time to perform a Kasai portoenterostomy (KPE). Little is known about the difficulties in the diagnosis and outcomes of BA in preterm infants (PBA). This study, which represents the first Italian report of preterm infants with BA, aims to describe a single-center experience of BA in preterm newborns. Methods We retrospectively reviewed all infants consecutively diagnosed with BA who underwent a Kasai procedure at the Bambino Gesù Children's Hospital between January 1998 and December 2021. Prematurity was defined as a gestational age (GA) of <37 weeks. Demographic, laboratory, and histology data were recorded, and the main outcomes considered were clearance of jaundice (COJ), native liver survival, and mortality. Results A total of 21 PBA were compared with 117 term BA controls (TBA). The median GA of PBA was 35.1 (32-36.1) weeks, with a mean birth weight of 2,100 (1,897-2,800) g. Age at first presentation was significantly lower in PBA patients: 46 (22-68) vs. 61 (44-72) days; p = 0.02. The median age at KPE was similar between the two groups: 70 days (33 corrected) for PBA vs. 67 in TBA; p = 0.8. At the time of surgery, median serum bilirubin was lower in the PBA group (7.7 vs. 8.6 mg/dl, p = 0.04). Similarly, the median APRi at the time of KPE was lower but not significant in the PBA group: 1.09 vs. 1.16; p = 0.8. No differences were found in terms of COJ between the PBA and TBA groups: n = 9 (43%) vs. 34 (35%); p = 0.2. Overall native liver survival was similar between the two groups: 8.6 (4.8-12.2) for the PBA group vs. 7.6 (5.6-9.5) years for the TBA group with no significant differences; p = 0.45. Post-KPE native liver survival was similar between the two groups: 38% vs. 52% at 5 years for the TBA and PBA groups, respectively; p = 0.54. Conclusion The PBA and TBA groups appear to have similar outcomes in terms of COJ, overall native liver survival, and 5-year liver survival. Considering the corrected GA, early KPE is related to lower cholestatic damage. Further multicenter studies are required.

Abstract
OBJECTIVES A connection between the bowel and bile ducts after the Kasai hepatoportoenterostomy (HPE) procedure poses a risk of ascending cholangitis. There were only a few evidence-based consensuses on the benefits of prophylactic antibiotics. This study aims to assess the value of prophylactic antibiotics in reducing the risk of cholangitis following the Kasai HPE procedure. METHODS Meta-analysis is performed using random-effects model from the search result of 5 online databases (PubMed, Google Scholar, EBSCO MEDLINE, ClinicalTrials.gov , and EuropePMC) from inception to October 27, 2021. The keywords used were "antibiotic," "antimicrobial," "Kasai," "portoenterostomy," "biliary atresia," and "bile duct atresia." Cochrane Risk of Bias tool and Newcastle-Ottawa Scale is used to assess the risk of bias. The outcomes are incidence of cholangitis and native liver survival. RESULTS Six studies consisting of 4 cohorts and 2 cross-sectional studies were extracted. A total of 714 patients reported different cholangitis incidence after prophylactic antibiotics administration post-Kasai HPE. The incidence of cholangitis following Kasai HPE was not statistically significant among participants. There is conflicting evidence on the efficacy of antibiotics in prolonging native liver survival. CONCLUSIONS The existing evidence does not support the administration of prophylactic antibiotics in preventing cholangitis after Kasai HPE among biliary atresia patients. Additionally, their roles in native liver survival are still inconclusive. The fact that there were heterogeneous method and antibiotic usage between existing studies must also be highlighted for better design in future studies.

Abstract
This article describes the experience of application of multipotent mesenchymal stromal cells in the complex therapy of severe recurrent cholangitis in 2 children with biliary atresia after Kasai surgery. In both children, hepatic cellular insufficiency and portal hypertension developed against the background of long-term inflammatory process poorly controlled by standard therapy, which was the indication for liver transplantation. During the course of mesenchymal stromal cells therapy, the relief of the inflammatory process and functional recovery of the liver were achieved. At the time of preparing the article, the follow-up of two children since the start of multipotent mesenchymal stromal cell therapy was 3 years 9 months and 2 years 6 months. No recurrence of cholangitis was observed in the patients during the follow-up period, the liver function was preserved. There are no indications for liver transplantation at this moment. Thus, despite the fact that the mechanisms of therapeutic action of multipotent mesenchymal stromal cells in biliary atresia require further investigation, we obtained promising results suggesting the possibility of using mesenchymal stromal cells in the treatment of postoperative complications in children with biliary atresia.

Abstract
Aim To detect the composition of the gut microbiota in biliary atresia after Kasai surgery. Methods Infants within six months after the Kasai operation who were diagnosed by cholangiography at Shanghai Children’s Hospital were enrolled in the study. Fecal samples were collected from diapers, placed into sterile tubes in the inpatient department or outpatient department and frozen at −80°C within half an hour. The gut microbiota was detected by 16S rRNA sequences. Then, the patients that were followed up to one year after the Kasai operation who suffered from cholangitis at least one time were grouped into the BAcho group, and the others were grouped into the BAnoncho group. Results Nine of 18 BA patients were grouped into the BAcho group, and the others were grouped into the BAnoncho group. In the BAcho group, AST, ALT and GGT were significantly increased compared to the BAnoncho group. The number of total OTUs (operational taxonomic units) in feces was more elevated in the BAnoncho group than in the BAcho group. In the BAnoncho group, the Chao index at the OTU level was significantly increased compared to that in the BAcho group (66.37 ± 21.5 vs. 45.64 ± 11.25, p = 0.02 < 0.05). Bifidobacterium was the most abundant genus in the BAnoncho group, accounting for 22.14%, and Klebsiella accounted for 22.74% in the BAcho group. Compared with the BAnoncho group, Bacteroides was significantly decreased in the BAcho group (p = 0.037). Conclusion The composition of the gut microbiota was different between BA with cholangitis and BA without cholangitis.

Abstract
Background Good outcomes of biliary atresia (BA) are conventionally achieved after early Kasai portoenterostomy (KP). However, in some recent pieces of literature, there are discrepancies in the influence of age in Kasai procedure on postoperative short-term prognosis. This meta-analysis aims to evaluate the effects of earlier KP on short-term surgical prognosis of BA and clarify these discrepancies in recent studies. Methods To identify related studies, PubMed, Embase, Web of Science, Cochrane, and the Chinese National Knowledge Infrastructure database were searched up to March 2022. Data for the impact of age at KP on clinical prognosis were extracted, including jaundice clearance rate (JCR) and native liver survival rate (NLSR). Results A total of 14 articles were included in the present study, which involve a total of 3,276 patients with BA who underwent Kasai procedure. Compared with patients older than 91 days of age, patients 90 days of age or younger exhibited significantly better JCR [odds ratio (OR), 3.05; 95% confidence interval (CI), 2.23–4.17; P < .001] and a more favorable NLSR (OR, 1.72; 95% CI, 1.37–2.15; P < .001). The NLSR of patients younger than 60 days of age was significantly higher than those of patients from 61 to 90 days of age (OR, 1.41; 95% CI, 1.18–1.68; P < .001). There was no significant difference in JCRs between patients aged 60 days of age or younger and those aged 61–90 days of age (OR, 1.31; 95% CI, 0.95–1.81; P = 0.10). Among patients 30 days of age or younger, 31–45 days of age, and 46–60 days of age, there were also no significant differences in JCR. Conclusion A significantly better short-term JCR and NLSRs were achieved among patients with BA treated using a KP procedure at ≤90 days of age compared with those treated at >90 days of age. There was no further improvement in the short-term JCR when the procedure was performed at ≤60 days compared with those treated at 61–90 days of age. However, treatment at ≤60 days of age was associated with a significant improvement in NLSR. Therefore, the timing of KP does exert an important effect on short-term clinical outcomes of patients with BA.

Abstract
Biliary atresia is a rare disease but remains the most common indication for pediatric liver transplantation as there are no effective medical therapies to slow progression after diagnosis. Variable contribution of genetic, immune, and environmental factors contributes to disease heterogeneity among patients with biliary atresia. Developing a deeper understanding of the disease mechanism will help to develop targeted medical therapies and improve patient outcomes.

Abstract
Cystic biliary atresia (BA) is a rare but an important type of BA. An antenatally detected cystic lesion at the porta hepatis raises the suspicion of cystic BA. It is very important to differentiate this from choledochal cyst in infants with cholestasis and cystic lesions. This case report outlines the clinical presentation and radiological findings of an infant who had an antenatally detected intra-abdominal cystic mass, thought to be a choledochal cyst.

Abstract
(1) Background: Acute cholangitis during the first year after Kasai hepatoportoenterostomy (HPE) has a negative impact on patient and native liver survival. There are no consistent guidelines for the definition, treatment, and prophylaxis of cholangitis after HPE. The aim of this study was to develop definition, treatment, and prophylaxis guidelines to allow for expeditious management and for standardization in reporting. (2) Methods: the Delphi method, an extensive literature review, iterative rounds of surveys, and expert panel discussions were used to establish definition, treatment, and prophylaxis guidelines for cholangitis in the first year after HPE. (3) Results: Eight elements (pooled into two groups: clinical and laboratory/imaging) were identified to define cholangitis after HPE. The final proposed definitions for suspected and confirmed cholangitis are a combination of one element, respectively, two elements from each group; furthermore, the finding of a positive blood culture was added to the definition of confirmed cholangitis. The durations for prophylaxis and treatment of suspected and confirmed cholangitis were uniformly agreed upon by the experts. (4) Conclusions: for the first time, an international consensus was found for guidelines for definition, treatment, and prophylaxis for cholangitis during the first year after Kasai HPE. Applicability will need further prospective multicentered studies.

Abstract
Kasai procedure (KP) and liver transplantation (LT) represent the only therapeutic options for patients with biliary atresia (BA), the most common indication for LT in the pediatric population. However, KP represents by no means a radical option but rather a bridging one, as nearly all patients will finally require a liver graft. More and more experts in the field of transplant surgery propose that maybe it is time for a paradigm change in BA treatment and abandon KP as transplantation seems inevitable. Inadequacy of organs yet makes this option currently not feasible, so it seems useful to find ways to maximize the efficacy of KP. In previous decades, multiple studies tried to identify these factors which opt for better results, but in general, outcomes of KP have not improved to the level that was anticipated. This review provides the framework of conditions which favor native liver survival after KP and the ones which optimize a positive LT outcome. Strategies of transition of care at the right time are also presented, as transplantation plays a key role in the surgical treatment of BA. Future studies and further organization in the transplant field will allow for greater organ availability and better outcomes to be achieved for BA patients.

Abstract
Portoenterostomy (PE) has remained as the generally accepted first line surgical treatment for biliary atresia (BA) for over 50 years. Currently, close to half of BA patients survive beyond 10 years with their native livers, and most of them reach adulthood without liver transplantation (LT). Despite normalization of serum bilirubin by PE, ductular reaction and portal fibrosis persist in the native liver. The chronic cholangiopathy progresses to cirrhosis, complications of portal hypertension, recurrent cholangitis or hepatobiliary tumors necessitating LT later in life. Other common related health problems include impaired bone health, neuromotor development and quality of life. Only few high-quality trials are available for evidence-based guidance of post-PE adjuvant medical therapy or management of the disease complications. Better understanding of the pathophysiological mechanisms connecting native liver injury to clinical outcomes is critical for development of accurate follow-up tools and novel therapies designed to improve native liver function and survival.

Abstract
OBJECTIVE Biliary atresia (BA) is a neonatal liver disease and requires Kasai portoenterostomy. Many patients develop postoperative cholangitis, resulting in a poor prognosis. The preventive strategy of antibiotics is empirical and lacks a standard regimen. We aimed to analyze the effect of different durations of prophylactic intravenous antibiotics against post-Kasai cholangitis. STUDY DESIGN A single-center, open-labeled, randomized clinical trial was performed from June 2016 to August 2017. One hundred and eighty BA patients were recruited and randomized into a short-term (n = 90) and a long-term (n = 90) treatment group, and prophylactic intravenous antibiotics were used for 7 versus 14 days, respectively. The primary outcome was the overall cholangitis incidence within 6-months post-Kasai portoenterostomy. The secondary outcomes included cholangitis incidence within 1 and 3 months post-Kasai portoenterostomy, the onset and average episodes of cholangitis, jaundice clearance rate, native liver survival rate, and adverse events within 6-months post-Kasai portoenterostomy. RESULTS The cholangitis incidence within 6-months post-Kasai in the short-term group was similar to the long-term group (62% vs. 70%, p = 0.27) with intention-to-treat and pre-protocol analysis. There was no significant difference in jaundice clearance rate or native liver survival rate between the two groups. However, the percentage of early onset (61% vs. 38%, p = 0.02) and average episodes (2.4 ± 0.2 vs. 1.8 ± 0.1 episodes, p = 0.01) of cholangitis were lower in the long-term group. CONCLUSION Long-term intravenous antibiotics can be replaced by the short-term regimen in the general protection against post-Kasai cholangitis.

Abstract
PURPOSE There is no consensus regarding adjuvant therapies following Kasai portoenterostomy (KP) for biliary atresia (BA). This study aimed to analyze the effect of extended perioperative intravenous antibiotics (PI-Abx) and adjuvant corticosteroid on cholangitis and jaundice clearance rates in the 3 years post-KP in children with BA. METHODS Data of patients who underwent KP between 1999-2018 at a single center were retrospectively analyzed. Group A (1999-2010) received PI-Abx for 5 days, Group B (2010-2012) received PI-Abx for 5 days plus low-dose prednisolone (2 mg/kg), and Group C (2012-2017) received PI-Abx for 14 days plus high-dose prednisolone (5 mg/kg). RESULTS Fifty-four patients were included with groups A, B, and C comprising 25, 9, and 20 patients, respectively. The number of episodes of cholangitis was 1.0, 1.6, and 1.3 per patient (p=NS) within the first year and 1.8, 2.3, and 1.7 (p=NS) over 3 years in Groups A, B, and C, respectively. The jaundice clearance rate at 6 months was 52%, 78%, and 50% (p=NS), and the 3-year native liver survival (NLS) rate was 76%, 100%, and 80% (p=NS) in Groups A, B, and C, respectively. A near-significant association was observed between the incidence of cholangitis within the first year and decompensated liver cirrhosis/death at 3 years post KP (p=0.09). Persistence of jaundice at 6 months was significantly associated with decompensated cirrhosis/death at 3 years (p<0.001). CONCLUSION The extended duration of PI-Abx and adjuvant corticosteroids was not associated with improved rates of cholangitis, jaundice clearance, or NLS in patients with BA.

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
Biliary atresia (BA) is a fibro-obliterative condition of the biliary tree, presenting in infancy. The bilioenteric conduit formed at Kasai portoenterostomy (KPE), achieves restoration of bile flow in approximately 60% of infants. Even if the operation is successful, cirrhosis and its associated complications are, however, common. BA remains the leading cause for liver transplantation (LT) in children. Antibiotic, choleretic, and steroid therapy post-KPE have not convincingly reduced LT rates. Advances in molecular technology have enabled characterisation of the encoded genes of the gut microbiota (gut microbiome). The gut microbiome plays an important role in host metabolism, nutrition, and immune function, with alterations in its diversity and/or composition, known as dysbiosis, being described in disease states, including liver disease. Liver-gut microbiome exploration in adulthood largely focuses on nonalcoholic liver disease, cirrhosis (mainly alcohol- or viral-based aetiology) and cholestatic liver diseases (eg, primary sclerosing cholangitis), with microbial signatures correlating to disease severity. Investigation of the gut microbiota in BA had been limited to culture-based methodology, but molecular studies are emerging, and although in their infancy, highlight a potential pathogenic role for Enterobacteriaceae and Streptococcus, and a potential beneficial role for Bifidobacteria. Bacterial translocation, and the production of gut microbiome-derived metabolites, are key host-microbiome-mechanistic pathways in liver disease pathogenesis. Microbiome-targeted therapeutics for liver disease are in development, with faecal microbiota transplantation showing promise in cirrhosis. Could the gut microbiome be a novel modifiable risk factor in BA, reducing the need for LT?

Abstract
INTRODUCTION Evidence supports long-term oral antibiotic prophylaxis to prevent cholangitis after Kasai procedure. Data regarding perioperative intravenous prophylaxis are lacking. Ascending pathogens from the intestine are made responsible for recurrent cholangitis. Therefore, we analyzed the flora in the upper jejunum during the Kasai procedure and their potential impact on postoperative cholangitis. MATERIALS AND METHODS In 26 patients, swabs were taken at the bowel prepared for the Roux-en-Y-loop. Our postoperative protocol includes intravenous third-generation cephalosporins for 2 weeks and rectal steroids starting at day 4. Cholangitis was defined as the postoperative reappearance of acholic stools or increase of serum bilirubin in combination with fevers or increase of inflammatory parameters. In this scenario, Tazocin was administered for another 2 weeks. RESULTS Swabs remained sterile in nine patients (34.6%). In 17 patients (65.4%), gram-positive and gram-negative pathogens were identified; all belonging to physiological intestinal flora. A total of 96.2% pathogens were covered by the antibiotic prophylaxis. The cholangitis incidence was 55.6% in the sterile cohort, and 23.5% in the gram-positive and gram-negative cohort (p = 0.06). In the cholangitis cohort, no significant differences were detected for the age at Kasai and the pre- and postoperative total bilirubin. CONCLUSION We found that our antibiotic regiment covered bacteria in the upper gastrointestinal (GI) tract in the majority of our patients at the time of Kasai. Nonetheless, a significant proportion of patients developed signs of cholangitis. There was no higher rate of cholangitis in patients with resistant bacteria. Thus, our data do not support the hypothesis of extended postoperative intravenous antibiotics to prevent ascending cholangitis.

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
OBJECTIVES Biliary atresia (BA) is a rare and progressive idiopathic disease affecting the biliary tract that can lead to end-stage liver disease. The main treatment is Kasai portoenterostomy (KP). The use of adjuvant therapy (AT; prophylactic antibiotics and steroids) after KP aims to prevent cholangitis and reduce the need for liver transplantation (LT), but there is a lack of evidence on their effectiveness. We investigated the impact of significant changes in the post-KP protocol on the overall outcomes of BA. METHODS We enrolled 43 consecutive infants undergoing KP at Bambino Gesù Children's Hospital between July 2012 and October 2018. We compared AT (AT group; n=25) against no treatment (AT-free group; n = 18). RESULTS No significant differences in anthropometric and laboratory parameters were shown between the 2 groups at baseline and every study evaluation (1, 3, and 6 months). The incidences of clinical complications of liver disease were similar. Six months post-KP, the achievement of serum total bilirubin ≤1.5 mg/dL and satisfactory Pediatric End-Stage Liver Disease scores were not significantly different between the 2 groups. Cholangitis was observed in 30% of patients in the first 6 months postoperatively: 33% and 28% in the AT-free and AT groups, respectively (P = 0.18). Survival to LT listing at 12 months and without LT at 24 months were not significantly different between the 2 groups (P > 0.05). CONCLUSIONS AT after KP confirmed conflicting results; therefore, multicentered, prospective, randomized control studies are needed to better understand its utility after KP, especially in the multidrug resistance spread era.

Abstract
Several patient and treatment related factors significantly modify outcomes of biliary atresia. The extremely variable prognosis mandates intensive postoperative monitoring following portoenterostomy. Accurate prediction of outcome and progression of liver injury would enable individualized treatment and follow-up protocols, patient counseling and meaningful stratification of patients into clinical trials. While results on most biomarkers of cholestasis, hepatocyte function, fibrosis and inflammation studied so far are inconsistent or have not been validated in independent patient cohorts, postoperative serum bilirubin level 3 months after portoenterostomy remains the most accurate clinically feasible predictor of native liver survival. Although liver stiffness and a novel marker of cholangiocyte integrity, serum matrix metalloproteinase-7, correlate with liver fibrosis and may discriminate biliary atresia from other causes of neonatal cholestasis, further information on their ability to predict portoenterostomy outcomes is needed. Recent gene expression profiling has shown promise in overcoming the sampling error associated with histological quantification of liver fibrosis, and provides an important possibility to stratify patients for clinical trials according to the prognosis of native liver survival already preoperatively. As activity and extent of ductular reaction is linked with progression of liver fibrosis in cholangiopathies, further research is also warranted to evaluate predictive value of ductular reaction, matrix metalloproteinase-7 and the underlying gene expression signatures in relation to circulating bile acids in biliary atresia. Discovery of accurate predictive tools will ultimately increase our understanding of the unpredictable response to surgery and pathophysiology of progressive liver injury in biliary atresia.

Abstract
BACKGROUND Kasai portoenterostomy (KPE) remains the first-line operation for patients with biliary atresia (BA), but ultimately fails in up to 60% of cases. This study sought to identify factors contributing to hospital readmission and early liver transplant. METHODS The Nationwide Readmissions Database from 2010 to 2014 was used to identify patients with BA who underwent KPE on index admission. Patient factors, hospital characteristics, and complications of BA were compared by readmission rates and rate of liver transplant within 1 y. The results were weighted for national estimates. RESULTS Nine hundred and sixty three patients were identified. The readmission rate within 30-d was 36% (n = 346) and within 1-y was 67% (n = 647). Only 9% (n = 90) received a liver transplant within a year. The most common complications after KPE were cholangitis in 58%, decompensated cirrhosis in 54%, and recurrent jaundice in 34%. Male patients (OR 1.5, P = 0.02) with comorbid gastrointestinal anomalies (OR 2.1, P < 0.01) from lower income households (OR 4.6, P < 0.01) and early development of cirrhosis (OR 3.0, P < 0.01) were more likely to be readmitted. Liver transplant was more common in men (OR 4.0, P < 0.01) and those from lower income households (OR 5.2, P < 0.01) with decompensated cirrhosis (OR 8.6, P < 0.01), cholangitis (OR 5.0, P < 0.01), or sepsis (OR 5.7, P < 0.01) on index admission. CONCLUSIONS This is the first nationwide study to evaluate readmissions in patients with BA undergoing KPE. Although KPE is a lifesaving procedure, hospital readmission rates are high and complications are common. Cholangitis, early progression of cirrhosis, and infections are highly associated with readmission and failure of KPE.

Abstract
BACKGROUND Biliary atresia (BA) is an obstructive hepatobiliary disease which manifests during infancy. Kasai portoenterostomy (KPE) is the preferred operation for BA, supplemented with glucocorticoids, antibiotics, and choleretic agents. A great deal of research has been carried out regarding diagnosis, operation, and adjuvant therapies of BA, but no consensus had been reached. To understand the variation in diagnosis and treatment strategies of BA across mainland China and to help achieve a unified treatment strategy in the future, this investigation was carried out. METHODS This investigation was conducted via electronic questionnaire. The centres were divided into three groups based on their annual caseload: low (0-20)-, mid (21-40)-, and high (≥ 41)-volume group. Differences in the clinical practice among three groups were analyzed by Chi-square test and considered statistically significant at P < 0.05. RESULTS 41 Centres from 26 different administrative regions were involved. The average age at KPE was mainly 51-60 days (39%, 16/41) and 61-70 days (32%, 13/41). The annual caseload was 0-20 patients in 17 centres, 21-40 patients in 11 centres, and > 40 patients in 13 centres. Preoperative ultrasound and intraoperative cholangiography were performed in all centres. Low-volume centres had a high proportion of MRI (P = 0.005), while the high-volume group had a high proportion of LSM (P = 0.015). Open KPE without liver mobilisation is the most common surgical procedure (71%, 29/41). Open KPE without liver mobilisation was more commonly used in low-volume group (P = 0.044), and laparoscopic KPE was mainly used in high-volume group (P = 0.011). The spur anti-reflux intestinal valve was performed in more than half of the centres (51%, 21/41). The length of the Roux-en-Y loop was ≥ 30 cm in the majority of centres (78%, 32/41). Glucocorticoids and antibiotics were used in most centres (90%, 37/41; 100%, 41/41) with marked variations in type, administration, dose, and duration. Oral ursodeoxycholic acid (UDCA) was used in 38 centres, in varying doses of 10-20 mg/kg/day. The duration of oral UDCA was over a year in 19 centres. CONCLUSION Mainland China has a large number of patients with biliary atresia. Diagnostic and surgical methods vary from centre to centre and are related to its caseload. In most centres, KPE is supplemented with glucocorticoids, antibiotics, and choleretic agents without a standard regimen.

Abstract
The treatment of biliary atresia (BA) is predominantly surgical with firstly an attempt at restoration of bile flow from the native liver by wide excision of the obstructed, obliterated extrahepatic biliary tree to the level of the porta hepatis and a portoenterostomy using a long Roux loop-Kasai portoenterostomy (KPE). Liver transplantation is reserved for those that fail this and for those where surgery is considered futile for reasons of age or stage of disease. As the aetiology of BA remains ill-defined, so adjuvant treatment has been largely based on pragmatism, trial and error. Systematic analysis of the few randomized placebo-controlled trial data and less well-controlled cohort studies have suggested benefit from post-operative high-dose steroids and ursodeoxycholic acid (UDCA) while the benefit of long-term prophylactic antibiotics, bile acid sequestrants (e.g., colestyramine) or probiotics remains unproven. Newer modalities such as antiviral therapy (AVT), immunoglobulin, FXR agonists (e.g., obeticholic acid), ileal bile acid transporter (IBAT) antagonists (e.g., maralixibat) remain unproven. This article reviews the current evidence for the efficacy of adjuvant medical therapy in BA.

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
RATIONALE Neonatal cholestasis is one of the most serious diseases in infancy. Progressive familial intrahepatic cholestasis (PFIC) is a disease that leads to intrahepatic cholestasis. It is one of the common causes of neonatal cholestasis in addition to biliary atresia (BA). The differential diagnosis of neonatal cholestasis is clinically challenging for pediatricians. PATIENT CONCERNS A 4-month-old female presented with severe jaundice, pruritus, and pale stool for 20 days. Abnormally strong echoes near the portal area, an abnormally small gallbladder with an irregularly stiff wall, and splenomegaly were identified on abdominal ultrasound. Blood tests showed elevated alanine aminotransferase, total bilirubin, conjugated bilirubin, gamma-glutamyltranspeptidase, and total bile acid levels. DIAGNOSIS Intraoperative cholangiography showed BA. ABCB4 gene mutation IVS13+6G>A/G was confirmed by genetic testing. The patient was diagnosed with BA combined with PFIC3. INTERVENTIONS Kasai portoenterostomy and ursodeoxycholic acid were used for treatment. OUTCOMES Her clinical symptoms and blood tests improved gradually. No recurrence was noted during 1 year of follow-up. LESSONS Additional examinations, such as genetic testing, should be considered in patients with BA who had refractory jaundice after Kasai portoenterostomy in order to exclude intrahepatic cholestasis.

Abstract
OBJECTIVES Cholangitis and bile lakes are incompletely understood complications after portoenterostomy (PE). We investigated relationships between recurrent cholangitis, bile lakes, and clinical outcomes as well as surgical management of bile lakes. METHODS In this retrospective observational single institution study medical records and imaging studies of all patients who had undergone PE for biliary atresia during 1987 to 2016 (N = 61) were reviewed. We related occurrence of cholangitis episodes with the presence of intrahepatic bile lakes, patient characteristics, and PE outcomes. Risk factors for recurrent cholangitis and bile lakes, and management of bile lakes were analyzed. RESULTS Despite routine antibiotic prophylaxis median of 3.0 cholangitis episodes (0.75 episodes/year) occurred in 48 (79%) patients. Intrahepatic bile lakes were discovered in 8 (13%) patients by 16 months after PE. Overall, 54% had survived with their native liver at median age of 7.3 years and 28 (46%) patients had ≥1 cholangitis episodes/year. Number and frequency of cholangitis episodes were >5 times higher among patients with bile lakes (P < 0.001). Six patients underwent Roux-en-Y bile lake-jejunostomy, resulting in regression/disappearance of bile lakes and normalization of serum bilirubin in 5 with reduction of median yearly cholangitis rate from 8.8 to 1.1 (P = 0.028) and native liver survival of 6.3 (range, 1.3-17) years after the operation. CONCLUSIONS Bile lakes are a significant risk factor for recurrent cholangitis after PE and efficiently treated by operative intestinal drainage providing prolonged jaundice-free native liver survival. Bile lakes should be actively screened among patients presenting with recurrent cholangitis after PE.

Abstract
BACKGROUND Cholangitis is the most common complication after the Kasai procedure. It can be life-threatening and may affect long- and short-term outcomes of children with biliary atresia. We summarize our experiences in the prevention of early-onset cholangitis. PATIENTS AND METHODS From January 2002 to March 2013, children with biliary atresia (BA) who underwent the Kasai procedure in the General Surgical Department were included in a retrospective cohort study. These patients were divided into group A (therapy 1) and group B (therapy 2) depending on the infection prevention protocol and occurrences of cholangitis within the six months after surgery were recorded. Two hundred eighteen children were included in this cohort study. Seventy-six children (35 females and 41 males) were included in group A. One hundred forty-two children (65 females and 77 males) were included in group B. Therapy 1 was our primary protocol and included a third-generation cephalosporin, metronidazole, and human immunoglobulin. Therapy 2 was a modification of therapy 1 that involved imipenem-cilastatin and human immunoglobulin. Statistical analyses were performed. A p value below 0.05 was regarded as significant. RESULTS In group A, 45 children developed cholangitis within the six months after the Kasai procedure. In group B, 14 of these children experienced post-operative cholangitis. A χ2 analysis was used to examine the difference in the incidence of cholangitis between groups A and B. There was a substantial difference in the morbidity of post-operative cholangitis between groups A and B (59.2% vs. 9.9%, p = 0.000). CONCLUSION Cholangitis in the early period after a Kasai procedure can be prevented effectively with an advanced prophylactic protocol.

Abstract
OBJECTIVES Kasai portoenterostomy (KPE) is the primary treatment for biliary atresia (BA) with subsequent liver transplantation in failed cases. The aim of this work was to study the outcome of KPE in children with BA and identify the factors predicting a successful KPE. METHODS Children diagnosed with BA and undergoing KPE between January 2010 and January 2018 were included in the study. A successful KPE was defined as decrease in bilirubin to less than 2 mg/dL at 6 months after KPE. Factors affecting the outcome (successful KPE and survival with native liver [SNL] at 2 years) were evaluated by logistic regression. RESULTS A total of 79 children with post-KPE BA were included. Successful KPE was achieved in 29 (36.7%) of 79 children undergoing KPE. The data for survival with native liver at 2 years were available for 61 children as 9 were lost to follow up before 2 years and another 9 were aged less than 2 years at the time of analysis. Twenty-seven (44.3%) of these 61 survived with their native liver at 2 years. On logistic regression analysis, lower age at KPE, use of postoperative steroids and absence of cholangitis were significant predictors of a successful KPE. A successful KPE at 6 months was the lone independent predictor of SNL at 2 years in these children. CONCLUSION Early age at KPE, use of postoperative steroid and prevention of cholangitis can result in successful KPE. Those with successful KPE are likely to survive with their native liver at 2 years.

Abstract
We addressed growth of biliary atresia (BA) patients living with native livers between ages 0-6 and effects of post-surgical corticosteroid treatment on growth. Growth charts of 28 BA patients born in Finland between 1987 and 2017 were retrospectively evaluated. Dosage and length of corticosteroid treatment and hydrocortisone substitution were reviewed. At birth, BA patients were shorter (median height - 0.6 (interquartile range (IQR) - 1.3 to - 0.1) SDS, n = 28, P < 0.001) than general population. Height remained stable during early childhood (median height - 0.6 (IQR - 1.4 to 0.1) SDS for girls and - 0.4 (IQR - 1.6 to 0.2) SDS for boys at 6 years of age). Patients were of normal height adjusted weight at 6 years with a median age and sex-adjusted body mass index (ISO-BMI) of 20.9 (IQR 19.3 to 25.0) for girls and 22.1 (IQR 20.7 to 25.6) for boys. Higher (≥ 50 mg/kg) cumulative post-portoenterostomy prednisolone dosage resulted in 0.18 SDS lower height per treatment week (β - 0.18, SE 0.04, P < 0.001) compared to lower dosage (< 50 mg/kg).Conclusion: BA patients grow normally during early childhood. As high postoperative corticosteroid dosage has a short-term negative effect on height, very high dosages should be avoided. What Is Known: • Growth of biliary atresia patients has mostly been shown to be within normal limits • Corticosteroids may decrease growth rate What Is New: • Biliary atresia patients surviving with their native livers are shorter than general population and their mid-parental target height at birth • A high (> 50 mg/kg) cumulative prednisolone dosage has a negative transitory impact on height gain after portoenterostomy.

Prognosis of Biliary Atresia After 2-year Survival With Native Liver: A Nationwide Cohort Analysis. J Pediatr Gastroenterol Nutr 2018; 67:689-694. [PMID: 30095577 DOI: 10.1097/mpg.0000000000002130] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/18/2022]
Abstract
OBJECTIVES The aim of the study is to determine the prognosis of patients with biliary atresia after 2 years of native liver survival (NLS) and to identify prognostic factors for continued NLS after 2 years of age. METHODS We retrospectively analyzed perioperative, laboratory, and outcome parameters of all biliary atresia patients in The Netherlands between January 1987 and June 2015 with NLS of at least 2 years. We compared parameters between patients who continued to have their native liver (NLS+) to those who did not, either by transplant or death (NLS-). RESULTS We included 100 patients. Upon a median follow-up of 16.4 years, NLS ended in 37% by liver transplantation (LTx) and in 6% by (pre-transplant) mortality. NLS rates at 5, 10, 15, 18 years of age were 89%, 72%, 60%, 54%, respectively. Corresponding overall survival rates were 98%, 90%, 87%, 87%, respectively. Six months post-Kasai, NLS+ patients had higher clearance of jaundice (COJ) rate, significantly lower total and direct serum bilirubin, aspartate-aminotransferase and alkaline phosphatase levels, compared with NLS- patients (each P < 0.05). Cox regression could only assess a significant effect of COJ on continued NLS. Main indications for LTx after the age of 2 were irreversible jaundice and portal hypertension. CONCLUSIONS Eighty-seven percent of patients with 2-year NLS reach adult age and more than 50% with their native liver. A pre-transplant mortality of 6%, however, exists among patients who reach the age of 2 years with their native livers. Early life parameters, other than COJ, did not have a significant effect on continued NLS after 2 years of age.

Abstract
PURPOSE This study compared the bacteriology and clinical outcomes between simple (SC) and intractable cholangitis (IC) after Kasai operation. METHODS Post-Kasai patients (n = 192) from 1980 to 2015 were retrospectively reviewed. The results of blood culture and clinical outcomes between the patients with SC and IC were compared. MAIN RESULTS A total of 102 cholangitic episodes in 68 patients were analyzed (SC vs IC = 76 vs 26). There were more IC episodes within the first year of Kasai operation (SC vs IC = 36.8% vs 61.5%, p = 0.022). The most common bacteria identified in SC and IC groups were Escherichia Coli and Staphylococcus aureus. Until the latest follow up, the native liver survival rates in patients with SC and IC were 75.0% and 50.0% (p = 0.89). Among the patients with IC, the native liver survival rate was significantly better in those with a positive culture (100% vs 20%, p = 0.001). CONCLUSION Intractable cholangitis is a common complication within the first year of Kasai operation and may be caused by a different spectrum of organisms. The identification of the bacteria by blood culturing may result in a better treatment outcome. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND/PURPOSE Biliary atresia is the most common reason for newborn cholestasis and pediatric liver transplantation. Even after normalization of serum bilirubin after portoenterostomy, most patients require liver transplantation by adulthood due to expanding fibrosis. We addressed contemporary outcomes of biliary atresia in the Nordic countries. METHODS Data on center and patients characteristics, diagnostic practices, surgical treatment, adjuvant medical therapy after portoenterostomy, follow-up and outcomes were collected from all the Nordic centers involved with biliary atresia care during 2005-2016. RESULTS Of the 154 patients, 148 underwent portoenterostomy mostly by assigned surgical teams at median age of 64 (interquartile range 37-79) days, and 95 patients (64%) normalized their serum bilirubin concentration while living with native liver. Postoperative adjuvant medical therapy, including steroids, ursodeoxycholic acid and antibiotics was given to 137 (93%) patients. Clearance of jaundice associated with young age at surgery and favorable anatomic type of biliary atresia, whereas annual center caseload >3 patients and diagnostic protocol without routine liver biopsy predicted early performance of portoenterostomy. The cumulative 5-year native liver and overall survival estimate was 53% (95% CI 45-62) and 88% (95% CI 83-94), respectively. Portoenterostomy age <65days and annual center caseload >3 patients were predictive for long-term native liver survival, while normalization of serum bilirubin after portoenterostomy was the major predictor of both native liver and overall 5-year survival. CONCLUSIONS The outcomes of biliary atresia in the Nordic countries compared well with previous European studies. Further improvement should be pursued by active measures to reduce patient age at portoenterostomy. RETROSPECTIVE PROGNOSIS STUDY Level II.

Abstract
OBJECTIVE To assess the efficacy of intravenous immunoglobulin (IVIG) as add-on treatment for intractable cholangitis (IC) after Kasai portoenterostomy (KPE) in biliary atresia (BA) patients. METHODS 113 BA patients who had one or more episodes of cholangitis after KPE were recruited in this study. According to whether response to routine conservative treatment, all patients were divided into IC group and simple cholangitis (SC) group. Meanwhile, patients with IC subdivided into IVIG group and control group according to whether application of IVIG. RESULTS The IC group had higher serum procalcitonin (PCT) (P = 0.014), C-reactive protein (CRP) (P = 0.023), and γ-Gltamyltranspeptidase (γ-GGT) (P = 0.031) level than the SC group. The IVIG group had shorter duration of fever after treatment (P = 0.011) and length of hospital stay (P = 0.018) than the control group. The time until recurrent episode of cholangitis was significant longer in IVIG group than in control group (P = 0.019). CONCLUSIONS IVIG as add-on treatment may be an effective treatment for the cholangitis acute episode, and we conclude by calling for more prospective studies to attest to the role of IVIG in the treatment of cholangitis.

Abstract
Given that the aetiology of biliary atresia (BA) is complex and that there is a multiplicity of possible pathogenic mechanisms then it is perhaps not surprising that the evidence for effect of a number of different agents is contradictory. Post-operative cholangitis for instance is common, bacterial in origin and various antibiotic regimens have been tested (although none in a randomized trial) but continuation beyond the early post-operative period does not appear to offer any greater protection. There is an inflammatory reaction in about 25-35% of cases of BA illustrated by abnormal expression of class II antigen and upregulation of ICAM, VCAM and E-selectin with an infiltrate of immune-activated T cells (predominantly CD4 + Th1 and Th17) and NK cells and a systemic surge in inflammatory cytokines (e.g. TNF-α, IL-2, IL-12). This has potential as a therapeutic target and is the main hypothesis behind the rationale use of steroids. The first report of steroids was published in 1985 by Karrer and Lilly as "blast" therapy to treat recalcitrant cholangitis, followed by a multiplicity of small-scale uncontrolled studies suggesting benefit. To date there has been one randomized placebo-controlled study with a low-dose (prednisolone 2 mg/kg/day) regimen (2007); one with a high-dose (IV prednisolone 4 mg/kg/day regimen) (2014); two prospective high-dose open-label studies (2013); a prospective comparison of low- and high-dose regimen and a large (380 infants) retrospective comparison. The most recent meta-analysis (2016) identified a significant difference in clearance of jaundice at 6 months (OR 1.59, 95% CI 1.03-2.45, P = 0.04), in patients treated with high-dose steroids, particularly if < 70 days at surgery. Ursodeoxycholic acid (UDCA) may increase choleresis or change the ratio of endogenous bile acids to a less hydrophobic and, therefore, less toxic millieu. UDCA may protect cholangiocyte membranes against damage and perhaps reduce the tendency to fibrogenesis. Biochemical benefit has been shown in a single crossover trial in older BA children who had cleared their jaundice. Other potential adjuvant therapies include immunoglobulin therapy, anti-viral agents and Chinese herbs although real evidence of benefit is lacking.

Treatment Policy and Liver Histopathology Predict Biliary Atresia Outcomes: Results after National Centralization and Protocol Biopsies. J Am Coll Surg 2017; 226:46-57.e1. [PMID: 28958913 DOI: 10.1016/j.jamcollsurg.2017.09.009] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2017] [Revised: 07/28/2017] [Accepted: 09/07/2017] [Indexed: 01/13/2023]
Abstract
BACKGROUND Different treatment policies can influence biliary atresia outcomes, but the pathophysiology of expanding fibrosis occurring even after successful portoenterostomy remains unclear. STUDY DESIGN Clearance of jaundice (COJ) (bilirubin <20 μmol/L), native liver survival, and overall survival rates of biliary atresia patients were analyzed before and after national centralization of management, as well as in relation to native liver histopathology of protocol biopsies. RESULTS Of the 59 patients, 35 were managed after centralization and received standardized postoperative adjuvant therapy, including corticosteroids. After centralization, age at portoenterostomy decreased from 73 days to 54 days (p = 0.014) and COJ rate increased from 42% to 80% (p = 0.005), 5-year native liver survival increased from 38% to 70% (p = 0.014), and 5-year overall survival increased from 68% to 94% (p = 0.007). High-grade portal inflammation at portoenterostomy predicted COJ (odds ratio 3.66; p = 0.011) and slower fibrosis progression (β = -0.74; p = 0.005). Native liver survival was extended in patients with high-grade portal inflammation (p = 0.002) and in patients whose bilirubin normalized within 3 months (p < 0.001). Portal inflammation and cholestasis reduced only after COJ (p < 0.001), and persisting ductal reaction, reflected by cytokeratin 7-positive proliferating bile ductules and periportal hepatocytes, correlated with follow-up fibrosis (r = 0.454 to 0.763; p < 0.001 to 0.003). Cytokeratin 7 immunopositivity of periportal hepatocytes increased after COJ (p = 0.015) and was the only predictor of follow-up liver fibrosis (β = 0.36; p = 0.002) in multiple regression. CONCLUSIONS Biliary atresia outcomes improved significantly after centralization and standardized management. Resolution of cholestasis and reduction of high-grade portal inflammation postoperatively predict slower fibrosis progression and improved native liver survival, and persisting ductal reaction parallels progressive native liver fibrosis despite COJ.
