Abstract
BACKGROUND Advances in chemotherapy, liver resection techniques, and pediatric liver transplantation have vastly improved survival in children with hepatoblastoma (HB). These are best managed by a multidisciplinary team (MDT) in a setting where all treatment options are available. Until recently, this was difficult to achieve in India. METHODS All children (<16 years) with HB treated in a pediatric liver surgery and transplantation unit between January 2011 and July 2016 were reviewed. Data regarding the clinical presentation, preoperative management, surgical treatment, postoperative course, and outcomes were extracted from a prospectively managed database. RESULTS Thirty children were treated for HB during the study period. Nine children were PRETEXT 4, 7 were PRETEXT 3, 13 were PRETEXT 2, and 1 was PRETEXT 1 (where PRETEXT is pretreatment extension). All children received a neoadjuvant chemotherapy before surgery followed by an adjuvant chemotherapy. Nineteen children had complete resection, while six underwent primary living donor liver transplantation. There were six mortalities including five children who poorly responded to chemotherapy with progressive tumor extension. At a median follow-up of 30 months, two children who underwent resection and one child who underwent liver transplant had disease recurrence. CONCLUSION Improved outcomes can be achieved in children with HB even in countries with limited resources when they are managed by MDTs with expertise in pediatric oncology, liver resection, and liver transplantation.

Abstract
We describe longitudinal results in a cohort of pediatric liver transplant patients successfully minimized to once daily CNI monotherapy for longer than five yr and assess changes in liver biochemistries and liver histology. A retrospective chart review of all pediatric liver transplant patients at a single center was performed. Biopsies and serum biochemistries (AST, ALT, total bilirubin, direct bilirubin, INR, creatinine) are reported at time points: PM, five-yr, seven-yr, and nine-yr post-minimization. Biopsies were assessed for inflammation and fibrosis using Ishak and Batts grading systems. Successful minimization to daily CNI monotherapy was defined as normal liver enzymes with no episodes of rejection. Thirty-three patients have successfully remained on once daily CNI for >5 yr, and 19/33 of these patients have serial liver biopsies available for review. We report on the clinical and histological findings of these 19 patients. All 19 patients continue to have normal liver biochemistries. On post-minimization biopsies, fibrosis progressed by ≥2 stages in one patient (5.3%) despite normal liver biochemistries. Carefully selected patients can tolerate minimization to once daily CNI monotherapy as few have progression of fibrosis.

Abstract
Liver retransplantation (re-LT) is required in patients with irreversible graft failure, but it is a significant issue that remains medically, ethically, and economically controversial, especially in living donor liver transplantation (LDLT). The aim of this study was to evaluate the outcome, morbidity, mortality, safety and prognostic factors to improve the outcome of pediatric living donor liver retransplantation (re-LDLT). Six of 172 children that underwent LDLT between January 2001 and March 2010 received a re-LDLT and one received a second re-LDLT. The overall re-LDLT rate was 3.5%. All candidates had re-LDLT after the initial LDLT. The overall actuarial survival of these patients was 83.3% and 83.3% at one and five yr, respectively. These rates are significantly worse than the rates of pediatric first LDLT. Vascular complications occurred in four patients and were successfully treated by interventional radiologic therapy. There were no post-operative biliary complications. One case expired because of hemophagocytic syndrome after re-LDLT. Although pediatric re-LDLT is medically, ethically, and economically controversial, it is a feasible option and should be offered to children with irreversible graft failure. Further investigations, including multicenter studies, are therefore essential to identify any prognostic factors that may improve the present poor outcome after re-LDLT.

Abstract
Liver retransplantation is routinely offered at our institution. Previous reports document that patient and graft survival is significantly less after pediatric rLT compared to primary LT. This has engendered intense debate regarding optimal allocation of organs. Here, we examine our program's approach to pediatric hepatic retransplantation related to patient factors affecting outcomes. Between 1997 and 2009, 272 LTs were performed in 234 patients (mean survival 1994 +/- 1367 days) at our center. Thirty-four patients required rLT including 10 who received their primary transplant elsewhere and four who required two retransplantations. Patient survival did not differ significantly between rLT and LT at one and three yr (p = 0.56). Graft survival between rLT and LT was also similar (p = 0.606) at one and three yr. No significant difference in graft or patient survival was noted between: Patients retransplanted <30 days after LT vs. those >30 days (p = 0.152); patients transplanted with technical variants vs. whole grafts (p = 0.966); technical variants utilized for LT vs. rLT (p = 0.713); rLT recipient age (< or >5 yr; p = 0.298); or ABOI for rLT and LT (p = 0.650). Retransplantation should be offered to optimize pediatric recipient survival after LT and offers similar survival as primary transplant.

Abstract
Nine to twenty-nine percent of pediatric liver transplant recipients require retransplantation. No previous pediatric study has proposed a prognostic scoring system. We have used the United Network for Organ Sharing transplantation database to conduct a retrospective cohort study of patients who were less than 18 years of age when they received their retransplant (n = 1130). Using a random two-thirds of the subjects, we developed a prognostic scoring system by performing a multivariate Cox analysis with non-laboratory clinical characteristics. The scoring system was verified in the remaining one-third of the subjects. Stratifying the verification group into risk groups by prognostic score demonstrated its predictive value. Those in the low-risk category had survival similar to that of primary liver transplant recipients. Those in the high-risk category had 2.4 (95% confidence interval: 1.6-3.7) times the risk of death or retransplantation as those in the low-risk category. Risk factors in the scoring system included being on life support at the time of retransplant, receiving a split liver graft, and having an original diagnosis of neonatal cholestasis, familial cholestasis, paucity of bile ducts, or congenital abnormalities. Protective factors in the scoring system included older age at the time of transplantation and having acute rejection contribute to graft failure. In conclusion, with simple clinical characteristics, this scoring tool can modestly discriminate between those children at high risk and those children at low risk of poor outcome after liver retransplantation.

Abstract
OBJECTIVES Although liver transplantation has been the standard of care therapy for life-threatening liver diseases for >20 years, data on the long-term impact of liver transplantation in children have been primarily limited to single-center experiences. The objective of this study was to characterize and evaluate the clinical course of children who have survived >or=5 years after pediatric liver transplantation in multiple centers across North America. PATIENTS AND METHODS Patients enrolled in the Studies of Pediatric Liver Transplantation database registry who had undergone liver transplantation at 1 of 45 pediatric centers between 1996 and 2001 and survived >5 years from liver transplantation were identified and their clinical courses retrospectively reviewed. RESULTS The first graft survival for 461 five-year survivors was 88%, with 55 (12%) and 10 (2%) children undergoing a second and third liver transplantation. At the 5-year anniversary clinic visit, liver function was preserved in the majority with daily use of immunosuppression therapy, including a calcineurin inhibitor and oral prednisone, reported by 97% and 25% of children, respectively. The probability of an episode of acute cellular rejection occurring within 5 years after liver transplantation was 60%. Chronic rejection occurred in 5% patients. Posttransplant lymphoproliferative disease was diagnosed in 6% children. Calculated glomerular filtration rate was <90 mL/minute per 1.73 m2 in 13% of 5-year survivors. Age- and gender-adjusted BMI>95th percentile was noted in 12%, with height below the 10th percentile in 29%. CONCLUSIONS Children who are 5-year survivors of liver transplantation have good graft function, but chronic medical conditions and posttransplantation complications affect extrahepatic organs. A comprehensive approach to the management of these patients' multiple unique needs requires the expertise and commitment of health care providers both beyond and within transplant centers to further optimize long-term outcomes for pediatric liver transplant recipients.

Abstract
Hepatoblastomas are the most common liver tumours in children. However, they are rare as compared to other solid malignancies. Thus, there is a need to integrate data from surgical centers around the world to provide a clearer view on the outcomes of multidisciplinary management of these tumours. We set out to retrospectively review our experience of patients with surgically resected hepatoblastomas looking at primary and secondary outcomes. Children diagnosed with hepatoblastoma and managed surgically (along with chemotherapy) at a single institution between 1 January 2000 and 31 May 2007, were analyzed. Out of the 18 patients, there were 12 male and 6 female patients. The median age was 18 months (range 8-72). A palpable mass in abdomen was the presenting symptom in 88% patients. Sixteen patients (88.8%) underwent major liver resection. Sixteen patients (88.8%) received preoperative chemotherapy. Complete gross resection (stage I and II) was achieved in all 18 patients (100%). The mortality and morbidity rates were 0 and 11.2%, respectively. The 80-month disease-free survival was 67%. This series, the largest from India in terms of surgical resections for hepatoblastoma, reaffirms that major liver resection can be performed with minimal perioperative mortality and morbidity and that the use of chemotherapy has definitely helped in down staging tumours for liver resection.

Abstract
INTRODUCTION Hepatoblastoma (HB) and hepatocellular carcinoma (HCC) are the most common primary liver cancers in children. Recent advances in management of pediatric liver cancer have improved disease-specific survival (DSS). This is a review of our experience with childhood liver malignancy over the past 3 decades. MATERIALS AND METHODS A retrospective chart review from 1975 to 2005 identified patients who were 18 years old or younger with a histologically confirmed diagnosis of primary liver cancer. Patients were staged according to the Children's Cancer Group and Pediatric Oncology Group (CCG/POG) system. Patients were followed up prospectively through clinic visits and mail correspondence. Standard statistical methods were used for comparison, risk, and survival analyses. RESULTS Fifty-two patients were confirmed to have primary liver cancers, where 24 (46%) patients had HB, 22 (42%) had HCC, 3 (6%) had sarcomas, and 3 (6%) had other histologies. Mean ages at presentation for HB and HCC were 3.2 and 13.1 years old, respectively. The most common presentations were abdominal mass (67%) and pain (40%). Most patients underwent major liver resection (n = 45, 87%), including: lobectomy (n = 25, 48%), and trisegmentectomy (n = 11, 21%). Three patients underwent liver transplantation (n = 3, 6%) for advanced local disease. Forty-five (87%) received primary or neoadjuvant and/or adjuvant chemotherapy. Patients had the following CCG/POG stages: I (n = 31, 60%), II (n = 6, 11.5%), III (n = 9, 17%), and IV (n = 6, 11.5%). Complete gross resection (stage I and II) was achieved in 37 (71%) patients. The perioperative mortality and morbidity rates were 0% and 29%, respectively. Patients with complete resection had significantly better 5-year DSS and median survival compared with incomplete gross resection: 62% vs 9% and 216 vs 18 months, P < .001. Patients treated during the period 1995-2005 had better 5-year DSS and median survival compared with those treated during 1975-1994: 68% vs 32% and 117 vs 27 months, P = .032. All 3 patients who underwent transplantation for conventionally unresectable disease are alive without disease recurrence (follow-up period, 1-15 years). CONCLUSION Complete resection of the pediatric primary liver tumors remains the cornerstone of treatment to achieve cure. Major liver resection can be performed with minimal perioperative mortality and morbidity. Patients with HB appeared to have better survival compared with patients with HCC, and there was significant improvement in the DSS of children treated in the recent decade. Liver transplantation in conjunction with chemotherapy may have an increasing role in the management of locally advanced primary liver cancers.

Abstract
The purpose of this study was to analyse the early and late results of paediatric liver transplantation (LT), with particular reference to complications that required surgical intervention. The charts of all children who underwent LT between 1990 and 2002 were reviewed retrospectively. Results were analysed with a minimum follow up of 9 months. Thirty-five children have undergone 38 LTs; 22 received grafts from their parents, 16 received cadaveric organs and three children had retransplantation. The ages of the children ranged from 12 to 168 months. Biliary atresia was the most frequent indication for transplant (n=27). Twenty-seven children had complications that required surgical or radiological interventional procedures. Vascular complications included hepatic artery thrombosis (n=2), hepatic vein (HV) thrombosis (n=1), and the majority being portal vein thrombosis (n=6). Bile leaks were observed in eight children. Other complications included intestinal perforation (n=2), intra-abdominal abscesses (n=1), wound dehiscence (n=2), post-operative bleed (n=2), intestinal obstruction (n=2), ventral hernia (n=1), and multiple abdominal wound sinuses (n=1). Three children underwent retransplantation, two for hepatic artery thrombosis with multiple episodes of cholangitis and intrahepatic biliomas and the third was done for hepatic vein thrombosis. Patient and graft survival at 1 year is 81.5 and 74.2%, respectively. Paediatric LT is associated with significant morbidity, the main complications being vascular and biliary.

Abstract
The aim of this study was to review our experience in orthotopic liver transplantation (OLT) for biliary atresia (BA) in children and analyze the survival and prognostic factors, and long-term outcome. We reviewed 332 OLTs performed in 280 children between the years 1986 and 2000. Univariate and multivariate analysis were performed on patient and graft survivals according to recipients' and donors' characteristics as well as intraoperative data. The long-term outcome among the 80 children living at 10 years after OLT was studied according to growth, immunosuppressive therapy, and liver and renal functions. Liver graft status was eventually documented by liver biopsy. Status of rehabilitation was assessed by reviewing school performance and employment. Overall patient survival rates at 1, 5, and 10 years were 85, 82, and 82%, respectively, and the corresponding overall graft survival rates were 77, 73, and 71%. In the multivariate analysis, we identified 4 independent prognostic factors: polysplenia syndrome (P = .03), United Network for Organ Sharing (UNOS) status (P = .05), donor's age (P = .01), and perioperative surgical complications (P = .03). At 10 years after transplant, 80 children were alive and had normal growth rates. Liver histology was abnormal in 73% of these long-term survivors, mainly due to chronic rejection and centrilobular fibrosis. A total of 63 of the 80 children attended normal school and in 55 children (69%) school performance was not delayed. In conclusion, we discovered that a good long-term survival could be achieved after liver transplantation for BA, with a 82% survival rate at 10 years with normal scholastic studies in the majority of recipients.

Abstract
BACKGROUND Little is known about long-term health after pediatric orthotopic liver transplantation (OLT). This study aimed to characterize the health status of recipients 10 years after OLT, with an emphasis on transplant-related morbidity and quality of life. METHODS We performed a retrospective database review of 32 children who underwent OLT before October 1992 at one center and were alive after 10 years. Outcome measures were assessed 10 years after OLT. Cantril's self-anchoring scale was used for global quality of life assessment. RESULTS Synthetic liver function at 10 years was preserved in all patients. The annual rate of episodes of acute rejection dropped markedly after the first year (1.4 at year 1 to 0.19 rejections/patient/year at year 10). Histologically confirmed chronic rejection developed in eight (25%) patients. At 10 years, long-term complications included mild to severe chronic renal failure (77%), mild chronic anemia (59%), and hypertension (25%). Significant growth retardation (z-score < -2), hyperlipidemia, and diabetes were uncommon. Infection requiring hospitalization occurred in 81% of the patients, with varicella zoster virus as the most common pathogen. Epstein-Barr virus-related malignancies affected 22% of patients. Ten-year survivors perceived quality of life as very good. Self-reporting of drug nonadherence by seven (22%) adolescents may have contributed to development of late onset rejection in this subgroup. Conclusions. Children who are 10-year survivors of OLT have excellent graft function and, despite chronic extrahepatic morbidities, a self-reported high quality of life.

Abstract
Adolescence is a difficult time for transplant recipients; they must learn to take responsibility for their own behavior and medication, and to balance their developing sexuality in a body that has been transformed by the adverse effects of immunosuppression. More than 80% of children survive transplantation to adolescence and adulthood, thus long-term outcome and tailoring of immunosuppression is of great importance. To date, the most experience with long-term immunosuppression regimens is cyclosporine, which is well tolerated and effective. Long-term adverse effects include hypertension, nephrotoxicity, and post-transplant lymphoproliferative disease (PTLD). The recent development of tacrolimus has improved the cosmetic adverse effects related to cyclosporine, but has similar rates of hypertension and nephrotoxicity, and possibly a higher rate of PTLD. There has been a recent, welcome development in renal sparing drugs, such as mycophenolate mofetil, which has no cosmetic adverse effects, does not require drug level monitoring and is thus particularly attractive to teenagers. Recent surveys demonstrate recovery of renal function with mycophenolate mofetil, if started prior to irreversible renal dysfunction. There are currently little published data on the use of sirolimus (rapamycin) in the pediatric population, but preliminary studies suggest that the future use of interleukin-2 receptor antibodies may be beneficial for immediate post-transplant induction of immunosuppression. It is important when planning immunosuppression for adolescents to consider the effects of drug therapy on both males and females in order to maintain fertility and to ensure safety in pregnancy. Noncompliance is a problem in this age group, but adequate practical measures and support should reduce noncompliance, and allow good, long-term graft function.

Abstract
Adolescence is a difficult time for transplant recipients, who need to cope with the challenges of becoming independent from their parents, as well as taking responsibility for their own behavior and medication. They need to balance their developing sexuality with a body image which may be affected by the side-effects of immunosuppression. It is now anticipated that more than 80% of children will survive their transplant to become teenagers and adults, and it is therefore important to ensure that immunosuppressive medication is acceptable, convenient for drug level monitoring and free of significant long-term side-effects.

Abstract
PURPOSE The aim of this study was to analyze the early and late results of pediatric liver transplantation, with particular reference to complications that required surgical or radiologic intervention. METHODS The records and code sheets of children who underwent liver transplantation in the authors' institution between September 1993 and December 2001 were reviewed. RESULTS Twenty-nine children (16 boys and 13 girls) underwent 31 liver transplantations (23 living donor, 8 cadaveric donor) during the study period. The ages of the children ranged from 4 months to 132 months (median, 16 months). Eighteen children had complications that required surgical or radiologic interventional procedures. Complications included, among others, hepatic vein thrombosis (n = 1, 3%), hepatic vein stenosis (n = 2, 7%), portal vein thrombosis (n = 2, 7%), biliary stricture (n = 3, 10%), bile leakage (n = 2, 7%), hepatic artery pseudoaneurysm (n = 1, 3%), jejuno-jejunostomy leakage (n = 1, 3%), graft hepatitis (n = 1, 3%), and posttransplant lymphoproliferative disorder (n = 2, 7%). In addition, 6 children (21%) suffered from intraabdominal bleeding from a variety of causes. After appropriate interventions, at a median follow-up of 38 months (range, 1 to 96 months), patient and graft survival rates were 79% and 74%, respectively. The retransplantation rate was only 7%. There was no incidence of hepatic artery thrombosis. All living donors remain alive and well. CONCLUSIONS Complications are inevitable in pediatric liver transplantation. However, with timely recognition and active intervention, a good outcome can be achieved.

Abstract
INTRODUCTION Gingival overgrowth associated with immunosuppression following liver transplantation is a commonly recognized clinical problem. The aims of this study were to determine the incidence of gingival overgrowth in a group of children post liver transplantation and to compare gingival overgrowth in children receiving FK506 with those receiving cyclosporin. METHODS Seventy-nine children (aged 15-196 months) undergoing liver transplantation at Birmingham Children's Hospital between October 1998 and October 2000 were studied. Gingival overgrowth was assessed in a blinded fashion and scored in a previously validated manner. Gingival overgrowth scores of the patients on each immunosuppressant drug were then compared. RESULTS Fifty-two patients were treated with cyclosporin and 27 treated with tacrolimus. Eighteen children were also receiving nifedipine (also known to cause gingival overgrowth) and were considered separately. Of the 41 children receiving cyclosporin alone, 26 exhibited gingival overgrowth compared to zero of 20 patients receiving tacrolimus alone. Those children treated with immunosuppression plus nifedipine developed gingival overgrowth, however, this was much less marked in the tacrolimus group. CONCLUSION Tacrolimus, unlike cyclosporin, is not associated with gingival overgrowth when used for immunosuppression following liver transplantation in children, and may be the drug of choice for children.

Abstract
BACKGROUND Survival after liver transplantation has improved significantly over the last decade with pediatric recipients faring better than adults. The 20-year experience of pediatric liver transplantation at Children's Hospital of Pittsburgh is reported in terms of patient survival; graft survival in relation to age, gender, and immunosuppressive protocols; causes of death; and indications for retransplantation. METHOD From March 1981 to April 1998, 808 children received liver transplants at Children's Hospital of Pittsburgh. All patients were followed until March 2001, with a mean follow-up of 12.2+/-3.9 years (median=12.6; range=2.9-20). There were 405 female (50.2%) and 403 male (49.8%) pediatric recipients. Mean age at transplant was 5.3+/-4.9 years (mean=3.3; range 0.04-17.95), with 285 children (25.3%) being less than 2 years of age at transplant. Cyclosporine (CsA)-based immunosuppression was used before November 1989 in 482 children (50.7%), and the subsequent 326 recipients (40.3%) were treated with tacrolimus-based immunosuppression. Actuarial survival was calculated using the Kaplan-Meier statistical method. Differences in survival were calculated by log-rank analysis. RESULTS Overall patient survival at 1, 5, 10, 15, and 20 years was 77.1%, 72.6%, 69.4%, 65.8%, and 64.4%, respectively. There was no difference in survival for male or female patients at any time point. At up to 10 years posttransplant, the survival for children greater than 2 years of age (79.5%, 75.7%, and 71.6% at 1, 5, and 10 years, respectively) was slightly higher than those at less than 2 years of age (72.6%, 66.9%, and 65.3% at 1, 5, and 10 years, respectively). However, at 15 and 20 years posttransplant, survival rates were similar (>2 years=67.3% and 65.8%; <2 years=64.1% and 64.1%). A significant difference in survival was seen in CsA-based immunosuppression (71.2%, 68.1%, 65.4%, and 61%) versus tacrolimus-based immunosuppression (85.8%, 84.7%, 83.3%, and 82.9%) at 1, 3, 5, and 10 years, respectively (P=0.0001). The maximum difference in survival was noted in the first 3 months between CsA and tacrolimus; thus, indicating there may have been other factors (nonimmunological factors) involved in terms of donor and recipient selection and technical issues. The mean annual death rate beyond 2 years posttransplant was 0.47%, with the mean annual death rate for patients who received tacrolimus-based immunosuppression being significantly lower than those who received CsA-based immunosuppression (0.14% vs. 0.8%; P=0.001). The most common etiologies of graft loss were hepatic artery thrombosis (33.4%), acute or chronic rejection (26.6%), and primary nonfunction (16.7%). Of note, retransplantation for graft loss because of acute or chronic rejection occurred only in those patients who received CsA-based immuno-suppression. CONCLUSION The overall 20-year actuarial survival for pediatric liver transplantation is 64%. Survival has increased by 20% in the last 12 years with tacrolimus-based immunosuppression. Although this improvement may be the result of several factors, retransplantation as a result of acute or chronic rejection has been completely eliminated in patients treated with tacrolimus.

Abstract
OBJECTIVE To describe the epidemiology and causes of graft loss after pediatric liver transplantation and to identify risk factors. SUMMARY BACKGROUND DATA Graft failure after transplantation remains an important problem. It results in patient death or retransplantation, resulting in lower survival rates. METHODS A series of 157 transplantations in 120 children was analyzed. Graft loss was categorized as early (within 1 month) and late (after 1 month). Risk factors were identified by analyzing recipient, donor, and transplantation variables. RESULTS Kaplan-Meier 1-month and 1-, 3-, and 5-year patient survival rates were 85%, 82%, 77%, and 71%, respectively. Graft survival rates were 71%, 64%, 59%, and 53%, respectively. Seventy-one of 157 grafts (45%) were lost: 18 (25%) by death of patients with functioning grafts and 53 (75%) by graft-related complications. Forty-five grafts (63%) were lost early after transplantation. Main causes of early loss were vascular complications, primary nonfunction, and patient death. Main cause of late graft loss was fibrosis/cirrhosis, mainly as a result of biliary complications or unknown causes. Child-Pugh score, anhepatic phase, and urgent transplantation were risk factors for early loss. Donor age, donor/recipient weight ratio, blood loss, and technical-variant liver grafts were risk factors for late loss. CONCLUSIONS To prevent graft loss after pediatric liver transplantation, potential recipients should be referred early so they can be transplanted in an earlier phase of their disease. Technical-variant liver grafts are risk factors for graft survival. The logistics of the operation need to be optimized to minimize the length of the anhepatic phase.

Abstract
Liver transplantation (LTx) in children currently offers long-term survival rates of more than 80%. Many causes for Tx failure have been identified. However, the incidence and impact of multi-organ system failure (MOSF) are, to date, unknown. Therefore, in this study the role of MOSF after LTx in children was investigated with regard to outcome. The data of 114 children (53 girls, 61 boys; median age 4.3 yr) after first LTx were evaluated retrospectively. The definition of MOSF, as used by Wilkinson et al. [Crit Care Med 1986: 14: 271-274], was modified with regard to age-adjusted values. The influence of MOSF on patient survival was investigated by Kaplan-Meier analysis and multivariate regression analysis. Thirty-one of 114 children with orthotopic LTx developed MOSF (involving two or more organs). In total, 18 children died (15.8%) during the hospitalization; 16 of these had MOSF. Mortality related to two-organ failure was 29.4% (n = 5), to three-organ failure 78% (n = 7), and to four-organ failure 80% (n = 4). The highest mortality rates were observed in children with central nervous system (CNS) and cardiovascular failure, leading to a decreased probability of survival of 0.40 (p < 0.0001). Multi-variate analysis showed that CNS and cardiovascular failure were the most important risk factors for survival (p < 0.0001 and 0.056, respectively). Respiratory and renal failure, in univariate analysis, were significant contributors to poor survival, but had no statistically significant influence on outcome in multivariate analysis. Bone marrow insufficiency was found to have no influence on survival in either analysis. In multivariate analysis, the risk of development of MOSF was significantly increased by high numbers of transfused units of fresh-frozen plasma (FFP), the absence of rejection episodes, or a high bilirubin level prior to Tx. Hence, MOSF is a major factor contributing to the death of children early after LTx. CNS and cardiovascular failure carried the highest risk for a poor outcome. Other risk factors associated with the development of MOSF were: numbers of transfused units of FFP, absence of rejection episodes, and a high pre-Tx bilirubin level.

Abstract
Alagille syndrome is characterized by a paucity of bile ducts in the liver. The syndrome is associated with some or all the features of chronic cholestasis, cardiac disease, skeletal abnormalities, ocular defects and a distinctive facial appearance. The most common finding is chronic cholestasis, which causes intractable pruritus, xanthoma, deficiency of certain metabolic nutrients and growth retardation. Cardiac abnormalities are the most common cause of death in these patients. It is unusual to see the clinical picture of hepatic failure resulting in cirrhosis and requiring transplantation, but liver transplantation is indicated in Alagille syndrome patients who have chronic cholestasis. If the disease is diagnosed in childhood, transplantation can improve significantly the patient's prognosis and the quality of life. In recent years, auxiliary liver transplantation has gained popularity for treating both acute and chronic liver disease. Heterotopic segmental liver transplantation is an alternative treatment modality for patients who do not require native liver removal. Individuals with Alagille syndrome are good candidates for this type of treatment. J Pediatr Surg 36:667-671.

Abstract
Extrahepatic biliary atresia (EHBA) is an uncommon condition presenting in the first few weeks of life. It has an incidence of 0. 5-1 per 10 000 live births and is the end result of a destructive inflammatory process involving the extrahepatic biliary system of unknown aetiology occurring in utero. The net result is neonatal jaundice due to bile stasis, with subsequent hepatocellular damage and cirrhosis. In the untreated, patient death is inevitable within 2 years. Precise diagnosis (or exclusion) of EHBA in the persistently jaundiced infant must be made urgently and major surgery (hepatic portoenterostomy: Kasai procedure) carried out as soon as possible, preferably before 6-8 weeks of age. This review is concerned with anaesthesia for correction of EHBA in 50 consecutive patients and also outlines the experience gained in the largest European centre for correction of EHBA where the number of cases now approaches 500.

Abstract
BACKGROUND In this report, we compare the long-term outcome of pediatric liver transplantation (LTx) patients maintained with tacrolimus-based and with cyclosporine (CsA)-based immunosuppressive therapy. We examine long-term patient and graft survival, the incidence of rejection, and immunosuppression-related complications. METHOD There were 233 consecutive primary LTx in children (ages <18 years) performed between October 1989 and December 1994 with tacrolimus-based immunosuppressive therapy (Group I). These were compared with 120 consecutive primary LTx performed with CsA-based immunosuppressive therapy between January 1988 and October 1989(Group II). Children in both groups were followed until July 1999. Mean follow-up was 91.41+/-17.7 months (range 55.6-117.8) for Group I, and 128+/-6.1 months (range 116.7-138.6) for Group II. RESULTS At 9 years of follow-up, actuarial patient and graft survival were significantly improved (patient survival 85.41% in Group I vs. 63.8% in Group II, P=0.0001; graft survival Group I 78.9% vs. 60.8% Group II, P=0.0003) and the rate of re -transplantation was significantly lower among patients in Group I (12% in Group I vs. 22.5% in Group II P=0.01). Children in Group I also experienced a significantly reduced incidence of acute rejection (0.97 per patient Group I vs. 1.5 per patient Group II P=0.002) and significantly less steroid resistant acute rejection episodes (3.1% in Group I vs. 8.6% in Group II P=0.0001). The mean steroid dose was significantly lower in Group I compared with Group II at all time points (P=0.0001) after LTx. Freedom from steroid was also significantly higher in Group I compared with Group II at all time points after LTx (ranging from 78% to 84% in Group I and 9% to 32% in Group II during a 1- to 7-year posttransplant period P=0.0001). The rate of hypertension was significantly lower in Group I than Group II (P=0.0001), and the severity of hypertension (need for more than one anti-hypertensive medication) was also significantly lower in Group I than Group II (P=0.0001). Although the rate of posttransplant lymphoproliferative disorder (PTLD) was not significantly different (13.7% Group I vs.8.3% Group II, P=0.13), the survival after PTLD was significantly better for Group I at 81.2% than for Group II at 50% after 5 years (P=0.034). Conclusion. The results suggest that tacrolimus-based therapy provides significant long-term benefit to pediatric LTx patients, evidenced by significantly improved patient and graft survival, reduced rate of rejection, and hypertension with lower steroid doses.

Abstract
OBJECTIVE To summarize the long-term efficacy and safety of tacrolimus in orthotopic liver transplant (OLT) recipients, as well as to examine the factors that influence long-term morbidity and mortality rates. BACKGROUND Tacrolimus (FK506, Prograf) was introduced as primary immunosuppression for primary liver transplantation in 1989; many subsequent trials have verified the association of tacrolimus with decreased rates of acute rejection and steroid-resistant rejection after OLT. Cumulative experience with tacrolimus has also defined its short- and intermediate-term toxicity. METHODS One thousand consecutive patients undergoing primary OLT at a single center from August 1989 to December 1992, under tacrolimus immunosuppression, were followed until January 1999. Patients were categorized by age. Mean follow-up was 93.4+/-11 months after OLT. Patient survival, graft survival (with corresponding causes of death and retransplantation), and rejection rates (and corresponding doses of immunosuppression) were examined as efficacy parameters. Hypertension, renal function, incidence of malignancies, incidence of diabetes, and other toxicities were examined as safety parameters. RESULTS Actual 6-year overall patient survival rate was 68.1% and graft survival rate was 62.5%, with significant differences in the patterns of survival among the different age groups. After the first post-OLT year, infection, recurrence of disease, de novo malignancies, and cardiovascular events were the main causes of graft loss and death during the long-term follow-up. Graft loss related to either acute or chronic rejection was rare. The rate of acute rejection beyond 2 years was approximately 3% per year, and most were steroid-responsive. Approximately 70% of the patients were receiving tacrolimus monotherapy beyond year 1; at the latest follow-up, 74.2% were maintained on tacrolimus alone. In 6.1% of the survivors, end-stage renal disease developed during the follow-up period, requiring either dialysis or kidney transplantation. Hyperkalemia and hypertension was observed in approximately one third of the patients. Insulin-dependent diabetes mellitus (including patients who had diabetes before the transplant) was observed in 14% in year 1, dropping to 11% in year 7. In 82 patients, de novo malignancies developed; in 41 patients, lymphoproliferative disorders developed during the entire follow-up period. CONCLUSIONS Long-term patient and graft survival rates are excellent under tacrolimus immunosuppression. Pediatric patients have a better long-term outcome than adults, in part because of the limited recurrence of the original disease, which was the most common cause of late graft loss (other than patient death, most commonly the result of late de novo malignancies and cardiovascular events). Graft loss from late rejection was rare.

Abstract
We have studied 92 patients with Alagille syndrome (AGS) to determine the frequency of clinical manifestations and to correlate the clinical findings with outcome. Liver biopsy specimens showed paucity of the interlobular ducts in 85% of patients. Cholestasis was seen in 96%, cardiac murmur in 97%, butterfly vertebrae in 51%, posterior embryotoxon in 78%, and characteristic facies in 96% of patients. Renal disease was present in 40% and intracranial bleeding or stroke occurred in 14% of patients. The presence of intracardiac congenital heart disease was the only clinical feature statistically associated with increased mortality (P <.001). Initial measures of hepatic function in infancy including absence of scintiscan excretion were not predictive of risk for transplantation or increased mortality. The hepatic histology of these AGS patients showed a significant increase in the prevalence of bile duct paucity (P =.002) and fibrosis (P <.001) with increasing age. Liver transplantation for hepatic decompensation was necessary in 21% (19 of 92) of patients with 79% survival 1-year posttransplantation. Current mortality is 17% (16 of 92). The factors that contributed significantly to mortality were complex congenital heart disease (15%), intracranial bleeding (25%), and hepatic disease or hepatic transplantation (25%). The 20-year predicted life expectancy is 75% for all patients, 80% for those not requiring liver transplantation, and 60% for those who required liver transplantation.

Abstract
BACKGROUND/PURPOSE A successful Kasai procedure is effective in creating biliary drainage and radically altering the natural history of infants with biliary atresia (BA). Since its introduction in the 1950s, long-term follow-up would appear to show that only 30% to 50% of patients have a good long-term prognosis despite initially good surgical outcome. The authors reviewed their experience in treating BA from 1968 to 1997 to assess long-term outcome. MATERIALS AND METHODS The records of 163 patients treated surgically for BA from 1968 to 1997 were reviewed. Forty-eight (29%) were alive at the end of 1997, of whom, 14 had received liver transplants (LT). Surviving patients who had not undergone transplantation were divided into two groups according to clinical condition: group A, normal liver function without cholangitis (CG) and portal hypertension (PH) and group B, liver dysfunction with CG or PH. The study period was divided arbitrarily into three periods, 1968 to 1975 (period I, n = 34); 1976 to 1985 (period II, n = 81); 1986 to 1997 (period III, n = 48). RESULTS Thirty-four patients were alive without LT at the end of 1997. There were eight patients (mean age, 16.3+/-4.8 years) in group A, and 26 patients (mean age, 14.3+/-7.6 years) in group B. Recently, four group A patients (mean age, 19.3+/-1.9 years) shifted to group B because of sudden deterioration in condition involving severe CG with multiple bile lakes (n = 2), uncontrollable intestinal bleeding (n = 1), and liver atrophy (n = 1). Survival deteriorated with length of follow-up. There were three survivors from 34 patients treated in period I, 16 survivors from 81 patients treated in period II (three had LT), and 29 survivors from 48 patients treated in period III (11 had LT). CONCLUSIONS Although satisfactory bile drainage can be obtained with portoenterostomy, our data suggest that liver function can deteriorate progressively, with a possible turning point in late adolescence, indicating that as the length of follow-up increases, clinical assessment should be regular and comprehensive. The timing of LT in postoperative BA patients with deteriorating liver function is a vital management issue.

Abstract
Liver transplantation continues to be successful and effective treatment for acute and chronic liver failure, and many important lessons have been learned. The development of innovative operative techniques has much reduced the waiting list mortality rate and has extended transplantation to younger and sicker children and to those with functionally normal livers who may benefit from auxiliary liver transplantation. The incidence and range of postoperative complications have improved with increased medical and surgical expertise. As information on long-term outcome for liver transplantation is gained, it is clear that many children will benefit from early elective liver transplantation before the development of significant growth or psychosocial retardation. Early transplantation is also indicated in children with cirrhosis and intrapulmonary shunting or cystic fibrosis with moderate lung disease. During the same period, evolving medical therapy has altered the natural history, patient selection, and timing of transplantation in children with tyrosinaemia type I, primary bile acid disorders, neonatal haemochromatosis, and potentially, cystic fibrosis. It is now clear that children with significant multisystem disease, such as mitochondrial disorders or severe systemic oxalosis, are no longer suitable candidates for liver transplantation. The successful development of liver transplantation has brought good quality life to many children and their families. There are still many lessons to learn and there are future challenges such as the ever-increasing problems of donor scarcity and the search for potent but less toxic immunosuppressive agents.

Abstract
UNLABELLED The survival experience of 338 infants born with biliary atresia between January 1973 and December 1995 was analyzed. All the infants had their initial surgery at a single UK centre. These infants were divided into three groups based on year of birth; group 1 (1970s, n = 38); group 2 (1980s, n = 182), and group 3 (1990s, n = 118). The data from group 1 were incomplete and selected, and comparisons with the remaining groups were therefore restricted. However, all infants who had been treated since 1980 underwent portoenterostomy or hepaticojejunostomy and were included. RESULTS In the whole cohort there were 89 deaths (26%), 79 children (23%) who underwent liver transplantation and 170 children (50%) who were alive at last follow-up. The 5- and 10-year actuarial survival for group 2 was 50% and 41%, respectively and the 5-year actuarial survival for group 3 was 60%. Overall, 57 children have survived to 10 years after surgery for biliary atresia. There has been a progressive fall in the age at surgery from a median of 77 days in group 1, through 69 days in group 2 to 56 days in group 3 (P < .0001). However, there was no significant difference in outcome to 5 years between the age cohorts (< 40 days, 41 to 60 days, 61 to 99 days, and > or = 100 days; P > .1) for the infants treated since 1980 (n = 200). CONCLUSIONS Portoenterostomy is an effective long-term procedure for biliary atresia in about 40% to 50% of infants. The remaining 50% to 60% will require transplantation mostly within 2 years of age, although there is also a continuing need beyond 5 and 10 years. The age at surgery has limited usefulness as a predictor of survival after portoenterostomy and certainly should not be used to dictate primary treatment.
