Postoperative outcomes of acute-on-chronic liver failure in infants and children with biliary atresia. Pediatr Transplant 2024; 28:e14736. [PMID: 38602219 DOI: 10.1111/petr.14736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 02/02/2024] [Accepted: 02/20/2024] [Indexed: 04/12/2024]
Abstract
INTRODUCTION Acute-on-chronic liver failure (ACLF) is associated with increased mortality and morbidity in patients with biliary atresia (BA). Data on impact of ACLF on postoperative outcomes, however, are sparse. METHOD We performed a retrospective analysis of patients with BA aged <18 years who underwent LT between 2011 and 2021 at our institution. ACLF was defined using the pediatric ACLF criteria: ≥1 extra-hepatic organ failure in children with decompensated cirrhosis. RESULTS Of 107 patients (65% female; median age 14 [9-31] months) who received a LT, 13 (12%) had ACLF during the index admission prior to LT. Two (15%) had Grade 1; 4 (30%) had Grade 2; and 7 (55%) had Grade ≥3 ACLF. ACLF cohort was younger at time of listing (5 [4-8] vs. 9 [6-24] months; p < .001) and at LT (8 [8-11] vs. 16 [10-40] months, p < .001) compared to no-ACLF group. Intraoperatively, ACLF patients had higher blood loss (40 [20-53] vs. 10 [6-19] mL/kg; p < .001) and blood transfusion requirements (33 [21-69] vs. 18 [7-25] mL/kg; p = .004). Postoperatively, they needed higher vasopressor support (31% vs. 10.6%; p = .04) and had higher total hospital length of stay (106 [45-151] vs. 13 [7-30] days; p = .023). Rate of return to the operating room, hospital readmission rates, and 1-year post-LT survival rates were comparable between the groups. CONCLUSION Despite higher perioperative complications, survival outcomes for ACLF in BA after LT are favorable and comparable to those without ACLF. These encouraging data reiterate prioritization during organ allocation of these critically ill children for LT.

Abstract
BACKGROUND Liver transplantation is the main treatment for cholestatic liver disease and some metabolic liver diseases in children. However, no accurate prediction model to determine the survival probability of grafts prior to surgery exists. This study aimed to develop an effective prognostic model for allograft survival after pediatric liver transplantation. METHODS This retrospective cohort study included 2032 patients who underwent pediatric liver transplantation between January 1, 2006, and January 1, 2020. A nomogram was developed using Cox regression and validated based on bootstrap sampling. Predictive and discriminatory accuracies were determined using the concordance index and visualized using calibration curves; net benefits were calculated for model comparison. An online Shiny application was developed for easy access to the model. RESULTS Multivariable analysis demonstrated that preoperative diagnosis, recipient age, body weight, graft type, preoperative total bilirubin, interleukin-1β, portal venous blood flow direction, spleen thickness, and the presence of heart disease and cholangitis were independent factors for survival, all of which were selected in the nomogram. Calibration of the nomogram indicated that the 1-, 3-, and 5-year predicted survival rates agreed with the actual survival rate. The concordance indices for graft survival at 1, 3, and 5 years were 0.776, 0.757, and 0.753, respectively, which were significantly higher than those of the Pediatric End-Stage Liver Disease and Child-Pugh scoring systems. The allograft dysfunction risk of a recipient could be easily predicted using the following URL: https://aspelt.shinyapps.io/ASPELT/ / CONCLUSION: The allograft survival after pediatric liver transplantation (ASPELT) score model can effectively predict the graft survival rate after liver transplantation in children, providing a simple and convenient evaluation method for clinicians and patients.

Abstract
INTRODUCTION Liver transplantation (LT) has emerged as a lifesaving modality for many liver diseases in children. Pediatric LT is an established treatment in the Western world but is relatively a new procedure in resource-limited countries like Pakistan. The study aims to highlight the outcomes and survival of pediatric recipients from the first pediatric liver transplant center in Pakistan. METHOD A retrospective analysis of pediatric LT was done from 2012 to 2019. The study was conducted in the Hepatobiliary and liver transplant department of Shifa International Hospital (SIH), Islamabad. A detailed analysis for indications for pediatric LT, survival, and complications was done. RESULTS Forty-five patients under 18 years of age underwent Living donor liver transplant (LDLT) in SIH. Median age was 9 years and M:F of 2:1. Cryptogenic liver disease followed by Wilson disease were the two most common indications of LT. The majority of patients had chronic liver disease 34 (75%) while 11 (24%) had acute liver failure. The right lobe graft was the most common type of graft 19 (42.2%). Thirty days, 1-year, 3-year, and 5-year survival was 77.8%, 75.6%, 73.3%, and 60.6% respectively. Mortality was highest in patients with biliary atresia 4 (33%). Causes of death included pulmonary embolism, sepsis, surgical complications, and acute kidney injury. Mean survival was 88.850 months (±7.899) (CI 73.369-104.331). CONCLUSION Pediatric LDLT has offered disease-free survival for patients. Survival can improve further with nutritional rehabilitation and anticipation and management of post-operative complications.

Abstract
Low skeletal muscle mass may develop in children with end-stage liver disease, affecting postoperative outcomes. We retrospectively investigated whether preoperative low muscle mass was associated with early postoperative outcomes in pediatric patients undergoing living donor liver transplantation (LDLT). Electronic medical records of children (age below 12 y) who underwent LDLT between February 1, 2007, and January 31, 2018, were reviewed. The cross-sectional areas of psoas, quadratus lumborum, and erector spinae muscles at the level of fourth-fifth lumbar intervertebral disks were measured using abdominal CT images, divided by the square of the height and were added to obtain the total skeletal muscle index (TSMI). The patients were divided into two groups according to the median TSMI in the second quintile (1859.1 mm 2 /m 2 ). Complications in the early postoperative period (within 30 d after surgery) classified as Clavien-Dindo grade 3 or higher were considered major complications. Logistic regression analyses were performed to determine the association between preoperative low muscle mass and early postoperative outcomes. In the study population of 123 patients (median age, 14 mo; range, 8-38 mo) who underwent LDLT, 29% and 71% were classified in the low (mean TSMI, 1642.5 ± 187.0 mm 2 /m 2 ) and high (mean TSMI 2188.1 ± 273.5 mm 2 /m 2 ) muscle mass groups, respectively. The rates of major complications, mechanical ventilation >96 hours, intensive care unit stay >14 days, hospital stay >30 days, and in-hospital mortality were not significantly different between the 2 groups. Additionally, adverse outcomes according to pediatric end-stage liver disease scores and sex were not significantly different between the 2 groups. In conclusion, preoperative low muscle mass defined by TSMI was not associated with early postoperative outcomes in pediatric patients undergoing LDLT.

Cost-effectiveness analysis of liver transplantation in biliary atresia according to the severity of end-stage liver disease. BMC Pediatr 2023; 23:439. [PMID: 37660000 PMCID: PMC10474723 DOI: 10.1186/s12887-023-04270-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 08/24/2023] [Indexed: 09/04/2023] Open
Abstract
BACKGROUND Timing for liver transplantation (LT) in biliary atresia (BA) children with end-stage liver disease (ESLD) is associated with all-cause mortality. The cut-off value of pediatric end-stage liver disease (PELD) score for LT consideration varies across institutions. We aimed to determine the cost-effectiveness of LT to prevent death among BA children registered on the waiting list with different severities of ESLD. METHODS Subjects were BA children aged < 12 years at a transplant center between 2010 and 2021. A decision tree was developed for cost-effectiveness analysis from a hospital perspective to compare all-cause death between patients initially registered with a low PELD score (< 15) and a high PELD score (≥ 15). Each patient's direct medical cost was retrieved from the beginning of registration until 5 years after LT, adjusted with an inflation rate to 2022 Thai Baht (THB). RESULTS Among 176 children, 138 (78.4%) were initially registered with the high PELD score. The cost and mortality rate of the low PELD score group (THB1,413,424 or USD41,904 per patient and 31.6% mortality) were less than the high PELD score group (THB1,781,180 or USD52,807 per patient and 47.9% mortality), demonstrating the incremental cost-effectiveness ratio (ICER) of THB2,259,717 or USD66,994 per death prevented. The cost of early post-operative admission had the highest effect on the ICER. Considering the break-even analysis, cost among children initially registered at the low PELD score was also less expensive over time. CONCLUSIONS Registration for LT at PELD score < 15 was more cost-effective to prevent death among BA children with ESLD.

Abstract
BACKGROUND Vitamin D deficiency in patients with cholestasis is due to impaired intestinal vitamin D absorption, which results from decreased intestinal bile acid concentration. Patients with cholestasis usually do not achieve optimal vitamin D status when a treatment regimen for children without cholestasis is used. However, data on high-dose vitamin D treatment in patients with cholestasis are limited. METHODS This study is a prospective study that included pediatric patients with cholestasis (serum direct bilirubin > 1 mg/dL) who had vitamin D deficiency (serum 25-hydroxyvitamin D, 25-OHD, < 20 ng/mL). In Phase 1, single-day oral loading of 300,000 IU (or 600,000 IU if weight ≥ 20 kg) of vitamin D2 was administered, followed by an additional loading if serum 25-OHD < 30 ng/mL, and 4-week continuation of treatment using a vitamin D2 dose calculated based on the increment of 25-OHD after first loading. In Phase 2, oral vitamin D2 (200,000 IU/day) was administered for 12 days, followed by 400,000 IU/day of vitamin D2 orally for another 8 weeks if serum 25-OHD < 30 ng/mL. RESULTS Phase 1: Seven patients were enrolled. Three out of seven patients had a moderate increase in serum 25-OHD after loading (up to 20.3-27.2 ng/mL). These patients had conditions with partially preserved bile flow. The remaining four patients, who had biliary atresia with failed or no Kasai operation, had low increments of serum 25-OHD. Phase 2: Eleven patients were enrolled. Eight out of 11 patients had a moderate increase in serum 25-OHD after 200,000 IU/day of vitamin D2 for 12 days. Serum 25-OHD continued increasing after administering 400,000 IU/day of vitamin D2 for another 8 weeks, with maximal serum 25-OHD of 15.7-22.8 ng/mL. CONCLUSION Very high doses of vitamin D2 (200,000 and 400,000 IU/day) partly overcame poor intestinal vitamin D absorption and resulted in moderate increases in serum 25-OHD in pediatric patients with cholestasis, particularly when cholestasis was caused by uncorrectable bile duct obstruction.

Abstract
OBJECTIVES We aimed to determine which characteristics and management approaches were associated with postoperative invasive mechanical ventilation (IMV) and with a prolonged course of IMV in children post liver transplant as well as describing the utilization of critical care resources. DESIGN Retrospective, multicenter, cohort study of children who underwent an isolated liver transplantation between January 2017 and December 2018. SETTING Twelve U.S., pediatric, liver transplant centers. PATIENTS Three hundred thirty children post liver transplant admitted to the ICU. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Six patients died in our cohort. The median length of PICU stay was 4.5 days (interquartile range [IQR], 2.9-8.2 d). Most patients were initially monitored with arterial catheters (96%), central venous pressures (95%), and liver ultrasound (93%). Anticoagulation (80%), blood product administration (52.4%), and vasoactive agents (23.0%) were commonly used therapies in the first 7 days. In multivariable logistic regression analysis, age (adjusted odds ratio [aOR] 0.9 [0.86-0.95]), open fascia (aOR 7.0 [95% CI, 2.6-18.9]), large center size (aOR 4.3 [95% CI 2.2-8.3]), and higher Model for End-Stage Liver Disease/Pediatric End-Stage Liver Disease scores (aOR 1.04 [95% CI, 1.01-1.06]) were associated with postoperative IMV. In multivariable logistic regression analysis, postoperative day 0 peak inspiratory pressure (PIP) (aOR 1.2 [95% CI, 1.1-1.3]), large center size (aOR 2.9 [95% CI, 1.6-5.4]), and age (aOR 0.89 [95% CI, 0.85-0.95]) were associated with length of IMV greater than 24 hours. Length of IMV greater than 24 hours was associated with bleeding complications ( p = 0.03), infections ( p = 0.03), graft loss ( p = 0.02), and reoperation ( p = 0.03). CONCLUSIONS Younger age, preoperative hospitalization, large center size, and open fascia are associated with use of IMV, and younger age, large center size, and postoperative day 0 PIP are associated with prolonged IMV on multivariable analysis. Longer IMV is associated with negative outcomes, making it an important clinical marker.

Abstract
BACKGROUND Preoperative conditions in pediatric liver transplant recipients are understandably complex. Compared with adults, children have lesser compensatory abilities and demand greater precision during procedural executions. In the setting of end-stage liver disease, the heightened perioperative risk of coexistent cardiovascular pathology may impact graft survival as well. Requirements for anesthesia and perioperative management are thus more rigorous, calling for individualized treatments that reflect specific cardiovascular constraints and proposed surgical plans.
CASE SUMMARY Reports of perioperative anesthesia management and liver transplant prognostication in pediatric patients with concurrent atrial septal defects are scarce. Herein, we detail the course of liver transplantation in a child with dual afflictions, focusing on perioperative anesthesia management and the important contributions of the anesthesiologist (pre- and perioperatively) to a positive therapeutic outcome, despite the clinical hurdles imposed.
CONCLUSION Children with atrial septal defects bear substantially more than customary perioperative risk during orthotopic liver transplants, given their compromised cardiopulmonary reserves and functional states. Comprehensive preoperative cardiovascular assessments, including use of agitated-saline contrast echocardiography (to characterize intracardiac shunting) and multidisciplinary deliberation, may offer insights into structural cardiac pathophysiologic effects and transplant-related hemodynamic changes that impact new grafts. At the same time, active and effective monitoring and other measures should be taken to maintain hemodynamic stability in the perioperative period, avoid entry of bubbles into the circulation, and ease congestion in newly grafted livers. Such efforts are crucial for transplantation success and graft survival.

Abstract
BackgroundThe incidence of hepatic artery thrombosis in pediatric living donor liver transplantation (LDLT) is significantly higher than that in adults, and is closely related to the surgeon’s experience with hepatic artery anastomosis. However, there are few studies on the learning curve of hepatic artery anastomosis among surgeons.MethodsWe collected data related to 75 patients who underwent pediatric LDLT and hepatic artery anastomosis independently by the same surgeon. Cumulative sum method (CUSUM) was used to analyse the duration of hepatic artery anastomosis and determine the cut-off value. Patients were divided into two phases according to CUSUM. We analysed the intraoperative and postoperative data and survival outcomes of the included patients.ResultsTotal anastomosis duration decreased with an increased number of completed procedures, and the average duration was 42.4 ± 2.20 min. A cut-off value and two phases were identified: 1–43 cases and 44–75 cases. Intraoperative blood loss was significantly lower in phase 2 than in phase 1. The immediate functional changes of total bilirubin (TBIL) and direct bilirubin (DBIL) were significantly also lower in phase 2 than in phase 1. Other functional outcomes, postoperative complications, and the long-term survival rate were not significantly different between the two phases.ConclusionsTechnical competence in pediatric LDLT hepatic artery anastomosis may be achieved after completing 43 cases. It is a safe procedure with a surgical loupe that can be systematized and adopted by pediatric surgeons with sufficient experience via a relatively long learning curve.

Recent Improvement in Survival Outcomes and Reappraisal of Prognostic Factors in Pediatric Living Donor Liver Transplantation. Liver Transpl 2022; 28:1011-1023. [PMID: 34536963 DOI: 10.1002/lt.26308] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 09/02/2021] [Accepted: 09/10/2021] [Indexed: 12/16/2022]
Abstract
Living donor liver transplantation (LDLT) is a significant advancement for the treatment of children with end-stage liver disease given the shortage of deceased donors. The ultimate goal of pediatric LDLT is to achieve complete donor safety and zero recipient mortality. We conducted a retrospective, single-center assessment of the outcomes as well as the clinical factors that may influence graft and patient survival after primary LDLTs performed between 1994 and 2020. A Cox proportional hazards model was used for multivariate analyses. The trends for independent prognostic factors were analyzed according to the following treatment eras: 1, 1994 to 2002; 2, 2003 to 2011; and 3, 2012 to 2020. Primary LDLTs were performed on 287 children during the study period. Biliary atresia (BA; 52%), acute liver failure (ALF; 26%), and monogenic liver disease (11%) were the leading indications. There were 45 graft losses (16%) and 27 patient deaths (7%) in this population during the study period. During era 1 (n = 81), the cumulative survival rates at 1 and 5 years after LDLT were 90.1% and 81.5% for patients and 86.4% and 77.8% for grafts, respectively. During era 2 (n = 113), the corresponding rates were 92.9% and 92% for patients and 89.4% and 86.7% for grafts, respectively. During era 3 (n = 93), the corresponding rates were 100% and 98.6% for patients and 98.9% and 95.4% for grafts, respectively. In the multivariate analyses, primary diagnosis ALF, bloodstream infection, posttransplant lymphoproliferative disease, and chronic rejection were found to be negative prognostic indicators for patient survival. Based on generalized care guidelines and center-oriented experiences, comprehensive advances in appropriate donor selection, refinement of surgical techniques, and meticulous medical management may eventually realize a zero-mortality rate in pediatric LDLT.

Hepatic artery reconstruction using an operating microscope in pediatric liver transplantation-Is it worth the effort? Pediatr Transplant 2022; 26:e14188. [PMID: 34719848 DOI: 10.1111/petr.14188] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 10/19/2021] [Accepted: 10/23/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION In pediatric liver transplantation (pLT), hepatic artery thrombosis (HAT) is associated with inferior transplant outcome. Hepatic artery reconstruction (HAR) using an operating microscope (OM) is considered to reduce the incidence of HAT. METHODS HAR using an OM was compared to a historic cohort using surgical loupes (SL) in pLT performed between 2009 and 2020. Primary endpoint was the occurrence of HAT. Secondary endpoints were 1-year patient and graft survival determined by Kaplan-Meier analysis and complications. Multivariate analysis was used to identify independent risk factors for HAT and adverse events. RESULTS A total of 79 pLTs were performed [30 (38.0%) living donations; 49 (62.0%) postmortem donations] divided into 23 (29.1%) segment 2/3, 32 (40.5%) left lobe, 4 (5.1%) extended right lobe, and 20 (25.3%) full-size grafts. One-year patient and graft survival were both 95.2% in the OM group versus 86.2% and 77.8% in the SL group (p = .276 and p = .077). HAT rate was 0% in the OM group versus 24.1% in the SL group (p = .013). One-year patient and graft survival were 64.3% and 35.7% in patient with HAT, compared to 93.9% and 92.8% in patients with no HAT (both p < .001). Multivariate analysis revealed HAR with SL (p = .022) and deceased donor liver transplantation (DDLT) (p = .014) as independent risk factors for HAT. The occurrence of HAT was independently associated with the need for retransplantation (p < .001) and biliary leakage (p = .045). CONCLUSION In pLT, the use of an OM is significantly associated to reduce HAT rate, biliary complications, and graft loss and outweighs the disadvantages of delayed arterial perfusion and prolonged warm ischemia time (WIT).

Abstract
BACKGROUND Ischemic-type biliary lesions (ITBL) are accepted as the most incomprehensible biliary complications after living-donor liver transplantation (LDLT). Early predicting the development of ITBL in pediatric patients permits more preventive strategies. However, few studies have focused on the early prediction of ITBL. OBJECTIVE This study aimed to establish a nomogram including ultrasound-based multimodal imaging to predict ITBL in children with biliary atresia (BA) within 2 years after receiving LDLT. METHODS The records of 94 BA children with at least one year of follow-up after LDLT were reviewed retrospectively. They were randomly divided into a training cohort for constructing a nomogram (n=64) and a validation cohort (n=30). In the training cohort, patients diagnosed as ITBL were included in the ITBL group and those without any vascular and biliary complication were included in the non-ITBL group. Multivariate Cox regression was used for the establishment of the nomogram in predicting the risk of ITBL within 2 years post-LDLT. The discrimination and calibration of the nomogram were internally and externally validated. The performances of the nomogram and the individual components were compared by the area under the curve (AUC) of receiver operating characteristic (ROC) curve. RESULTS In the training cohort, 18 BA children were included in the ITBL group and 46 were in the non-ITBL group. Last pediatric end-stage liver disease (PELD) score, gamma-glutamyl transpeptidase (GGT), resistive index (RI), and liver stiffness measurement (LSM) were the independent predictors for the development of ITBL within 2 years post-LDLT. The nomogram incorporating these independent predictors showed good discrimination and calibration by the internal and external validation. Its performance was better than any individual component in predicting the prognosis (P < 0.05). CONCLUSION The established nomogram may be used to predict the risk of ITBL within 2 years post-LDLT in BA children.

Abstract
BACKGROUND Biliary atresia is a progressive obliterative cholangiopathy affecting both extrahepatic and intrahepatic biliary trees, resulting in fibrous obliteration of the biliary tract and subsequent development of cirrhosis. OBJECTIVE The aim of this study was to find noninvasive indices to predict the status of hepatic fibrosis in children with biliary atresia. MATERIALS AND METHODS We retrospectively measured the volume of the hepatic lobes and spleen from MR images, obtained biochemical data and analyzed the relationship between the imaging and biochemical indices, and the pathological status of hepatic fibrosis in 35 children with biliary atresia. RESULTS A combined index was obtained by logistic regression: logit (likelihood of cirrhosis) = 0.00043 x age at MR examination + 1.67 x aspartate aminotransferase and platelet ratio index (APRI) + 0.0029 x body-surface-area-adjusted left liver lobe volume (BSA adLLV) - 6.57 (log-likelihood chi-square P<0.05, pseudo-R2=0.59). The area under the receiver operator characteristic curve of age at MR examination, APRI, BSA adLLV and the combined index for prediction of cirrhosis were 0.91, 0.86, 0.83 and 0.94, respectively. The optimal cut-off value (sensitivity and specificity) of age at MR examination, APRI, BSA adLLV and combined index were 132 (86% and 92%), 1.3 (91% and 85%), 855.5 (96% and 62%) and 0.689 (91% and 92%). The accuracy of age at MR examination, APRI, BSA adLLV and combined index were 89%, 89%, 83% and 91%, respectively. CONCLUSION A combined noninvasive index of age, aspartate aminotransferase and platelet ratio index, and the body-surface-area-adjusted left liver lobe volume measured from MR images is a potential marker of liver cirrhosis in children with biliary atresia.

Abstract
Introduction: Surgical treatment of biliary atresia (BA) is still based on sequential strategy with Kasai hepatoportoenterostomy (KP) followed by liver transplantation (LT), in case of complicated secondary biliary cirrhosis. Concerns have been expressed regarding the risks of LT related to previous KP, suggesting primary LT as an exclusive treatment of BA. Methods: Single-center retrospective analysis including 393 pediatric patients who underwent LT for BA from 1993 to 2018, categorized into two groups: with (KP) or without (NoKP) previous KP. Pre-LT clinical condition was estimated considering age at LT, time on waiting list, pediatric end-stage liver disease score (PELD), and presence of portal vein hypoplasia. Post-LT outcome was evaluated considering patient and graft survival rates, and need for early reoperation due to abdominal or graft-related complications (<45 days after LT). Results: Two-hundred ninety-six patients (75.3%) were categorized in the KP group, and 97 (24.7%) in the NoKP group. Median age at LT was 1.14 years in the KP group and 0.85 years in the NoKP group (p < 0.0001). PELD score was significantly less severe in KP patients (p < 0.05). One-year patient survival rates were 96.9 and 96.8% in the KP and NoKP groups, respectively (p = 0.43), and the corresponding graft survival was 92.5 and 94.8% (p = 0.97). The need for early reoperation was more frequent in the KP group (29.8%) vs. NoKP group (12.4%, p = 0.01). The rate of bowel perforation was non-significantly higher in the KP group (8.1%) vs. NoKP group (3.1%, p = 0.11). Conclusions: The sequential strategy including KP and LT allowed performing LT in patients with significant older age and better clinical conditions, when compared to those transplanted without previous KP. Patient and graft survivals were not impacted by previous KP. Although previous KP was associated with an increased rate of post-LT surgical complications, bowel perforation and bleeding did not occur significantly more frequently. Such results support the current strategy based on sequential treatment.

Abstract
OBJECTIVES Liver transplant in pediatric patients with body weight < 10 kg poses a challenge to the entire liver transplant team. Many reports have considered 10 kg to be a cutoff pointfor body weightforfavorable posttransplant outcomes. With evolving surgical techniques and postoperative management, there is potential to improve outcomes in this subset of recipients. We compared the outcomes in pediatric patients with body weight < 10 kg with those > 10 kg; also, we studied the factors of influence. MATERIALS AND METHODS We performed a retrospective analysis to evaluate the outcomes of liver transplants in pediatric patients with < 10 kg body weight. The cohort consisted of 90 children subdivided into the following 2 subgroups: group A (n = 35) with > 10 kg body weight at liver transplant and group B (n = 55) with < 10 kg body weight at liver transplant. We compared the following pretransplant characteristics between the groups: graft weight, graft-to-recipient weightratio, cold ischemia time, warm ischemia times, and liver transplant outcomes. RESULTS Pediatric End-stage Liver Disease score was significantly higher in group B (score of 24) versus group A (score of 18). Group B had significantly higher graft-to-recipient weight ratio (2.8 in group B vs 1.7 in group A). Graft function showed no significant difference between the 2 groups. Portal vein thrombosis was seen only in group B, whereas biliary leaks were observed among 5 patients in group B and 1 patientin group A. Patient survivalrate was higherin group B (86%) than in group A (77%). CONCLUSIONS Pediatric patients weighing < 10 kg have similarif not better survivalrates after liver transplant compared with patients > 10 kg. Advancements in surgical techniques and a careful monitoring for complications and timely intervention are important to facilitate these outcomes.

Abstract
BACKGROUND Infections still represent the main factors influencing morbidity and mortality following liver transplantation. This study aimed to evaluate the incidence and risk factors for infection and survival after liver transplantation. METHODS We retrospectively examined medical records in 210 liver recipients who underwent liver transplantation between April 2015 and October 2017 in our hospital. Clinical manifestations and results of pathogen detection test were used to define infection. We analyzed the prevalence, risk factors and prognosis of patients with infection. RESULTS The median follow-up was 214 days; the incidence of infection after liver transplantation was 46.7% (n = 98) which included pneumonia (43.4%), biliary tract infection (21.9%), peritonitis (21.4%) and bloodstream infection (7.6%). Among the pathogens in pneumonia, the most frequently isolated was Acinetobacter baumanii (23.5%) and Klebsiella pneumoniae (21.2%). Model for end-stage liver disease (MELD) score (OR = 1.083, 95% CI: 1.045-1.123; P < 0.001), biliary complication (OR = 4.725, 95% CI: 1.119-19.947; P = 0.035) and duration of drainage tube (OR = 1.040, 95% CI: 1.007-1.074; P = 0.017) were independent risk factors for posttransplant infection. All-cause mortality was 11.0% (n = 23). The prognostic factors for postoperative infection in liver recipients were prior-transplant infection, especially pneumonia within 2 weeks before transplantation. Kaplan-Meier curves of survival showed that recipients within 2 weeks prior infection had a significantly lower cumulative survival rate compared with those without infection (65.2% vs. 90.0%; hazard ratio: 4.480; P < 0.001). CONCLUSIONS Infection, especially pneumonia within 2 weeks before transplantation, complication with impaired renal function and MELD score after 7 days of transplantation was an independent prognostic factor for postoperative infection in liver transplant recipients.

Abstract
BACKGROUND Living donor liver transplantation (LDLT) in children has achieved promising outcomes during the past few decades. However, it still poses various challenges. This study aimed to analyze perioperative risk factors for postoperative death in pediatric LDLT. METHODS We retrospectively analyzed medical records of pediatric patients who underwent LDLT surgery from January 1, 2014, to December 31, 2016, in our hospital. Predictors of mortality following LDLT were analyzed in 430 children. Cox regression and Kaplan-Meier curve analysis were used for covariates selection. A nomogram was developed to estimate overall survival probability. The performance of the nomogram was assessed using calibration curve, decision curve analysis, and time-dependent receiver operating characteristic curve. RESULTS Among the 430 patients in this cohort (median [interquartile range] age, 7 [6.10] mo; 189 [43.9%] female; 391 [90.9%] biliary atresia), the overall survival was 91.4% (95% confidence interval, 89.2-94.4), and most of the death events (36/37) happened within 6 months after the surgery. Multivariate analysis indicated that the Pediatric End-stage Liver Disease score, neutrophil lymphocyte ratio, graft-to-recipient weight ratio, and intraoperative norepinephrine infusion were independent prognostic factors. A novel nomogram was developed based on these prognostic factors. The C index for the final model was 0.764 (95% confidence interval, 0.701-0.819). Decision curve analysis and time-dependent receiver operating characteristic curve suggested that this novel nomogram performed well at predicting mortality of pediatric LDLT. CONCLUSIONS We identified several perioperative risk factors for mortality of pediatric LDLT. And the newly developed nomogram can be a convenient individualized tool in estimating the prognosis of pediatric LDLT.

Short- and Long-Term Outcomes After Live-Donor Transplantation with Hyper-Reduced Liver Grafts in Low-Weight Pediatric Recipients. J Gastrointest Surg 2019; 23:2411-2420. [PMID: 30887299 DOI: 10.1007/s11605-019-04188-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Accepted: 02/26/2019] [Indexed: 01/31/2023]
Abstract
OBJECTIVE To evaluate short- and long-term outcomes after live-donor liver transplantation (LT) with hyper-reduced grafts in low-weight pediatric recipients. LT is an established curative therapy for children with end-stage chronic liver disease or acute liver failure. A major problem in pediatric LT has been the lack of size-matched donor organs. The disadvantage of the use of large-for-size grafts is the insufficient tissue oxygenation and graft compression, which result in poor outcomes. The shortage of suitable donors is most notable in children under 10 kg. To overcome such obstacle, in situ hyper-reduced live-donor liver grafts have been introduced. Available articles in the literature are based on small samples and are deficient in long-term follow-up. METHODS A single-cohort, retrospective analysis was conducted including 59 pediatric patients under 10 kg who underwent hyper-reduced (in situ "a la carte" left lateral segment reduction) live-donor LT (LDLT) between February 1994 and February 2018. RESULTS The most frequent cause of liver failure was biliary atresia (70%). Median recipient weight was 8 kg. Vascular complications were confirmed in 15% of the sample, while 45% presented biliary complications. Median follow-up time was 40.3 months. Ten-year overall survival rate was 74%. Pediatric end-stage liver disease score > 23 was associated with a higher risk of post-operative complications. CONCLUSION LDLT can be undertaken in children with body weight < 10 kg achieving good results in high-volume centers by experienced surgeons.

Abstract
OBJECTIVES Wilson's disease (WD) is a metabolic disorder leading to hepatic and extrahepatic copper deposition. Several studies have reported that besides copper (Cu), iron (Fe) and zinc (Zn) are also accumulated at varying levels in various tissues in WD. However, there is not an adequate number of studies investigating the effects of Fe and Zn status on WD presentation and prognosis. We aimed to evaluate serum levels of ferritin (SFr), copper (SCu), and zinc (SZn) in WD and determine their role in disease presentation and prognosis. MATERIALS-METHOD We retrospectively reviewed the medical records of 97 pediatric patients with WD who were diagnosed and followed at İnönü University Pediatric Gastroenterology, Hepatology and Nutrition Department between January 2006 and May 2017. Serum Cu and Zn levels were analyzed by using flame atomic absorption spectrophotometer. Ferritin was analyzed by chemiluminescence immunoassay method. RESULTS Analysis of serum levels of the elements according to the type of presentation, there was no significant difference between the groups for ceruloplasmin. However, SCU, FSCu, SFr and 24 h urinary copper levels were significantly higher (p = 0.002, p = 0.003, p = 0.023 and p < 0.001, respectively) and SZn and CSZn levels were significantly lower (fulminant WD). p < 0.001, p < 0.001). There was a positive correlation between SFr, SCu serum levels and mortality scores (respectively, r: 0.501, 0.564 for PELD, r:0.490, 0.504 for MELD, r: 0.345, 0.374 for Dhwan), and a negative correlation between SZn level and mortality scores. (r:-0.650 for PELD, r:-0.703 for MELD, r:-0.642 for Dhwan) We used the ROC curves to determine the worst prognosis for fulminant Wilson disease. According to these limit values, we found that the sensitivity and specificity of FWD development was significantly higher. (for SZn sensitivity of 91.5%, a specificity of 100%, p=<0,001, for SCu predicted FWD development with a sensitivity of 100%, a specificity of 73.7%, p=<0,001, for SFr predicted FWD development with a sensitivity of 92.9%, a specificity of 66.2%, p < 0,001) CONCLUSION: Our study suggests that SFr, SCu, SZn levels might have prognostic importance for WD.

Abstract
Objective To overcome the shortage of appropriate-sized whole liver grafts for children, technical variant liver transplantation has been practiced for decades. We perform a meta-analysis to compare the survival rates and incidence of surgical complications between pediatric whole liver transplantation and technical variant liver transplantation. Methods To identify relevant studies up to January 2014, we searched PubMed/Medline, Embase, and Cochrane library databases. The primary outcomes measured were patient and graft survival rates, and the secondary outcomes were the incidence of surgical complications. The outcomes were pooled using a fixed-effects model or random-effects model. Results The one-year, three-year, five-year patient survival rates and one-year, three-year graft survival rates were significantly higher in whole liver transplantation than technical variant liver transplantation (OR = 1.62, 1.90, 1.65, 1.78, and 1.62, respectively, p<0.05). There was no significant difference in five-year graft survival rate between the two groups (OR = 1.47, p = 0.10). The incidence of portal vein thrombosis and biliary complications were significantly lower in the whole liver transplantation group (OR = 0.45 and 0.42, both p<0.05). The incidence of hepatic artery thrombosis was comparable between the two groups (OR = 1.21, p = 0.61). Conclusions Pediatric whole liver transplantation is associated with better outcomes than technical variant liver transplantation. Continuing efforts should be made to minimize surgical complications to improve the outcomes of technical variant liver transplantation.

A comparison of two validated scores for estimating risk of mortality of children with intestinal failure associated liver disease and those with liver disease awaiting transplantation. Clin Res Hepatol Gastroenterol 2014; 38:32-9. [PMID: 23856636 DOI: 10.1016/j.clinre.2013.06.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2013] [Revised: 06/05/2013] [Accepted: 06/19/2013] [Indexed: 02/04/2023]
Abstract
BACKGROUND AND AIMS To evaluate risk of mortality in children with intestinal failure associated liver disease (IFALD) compared with other liver disease using two validated scores. METHODS Sixty-seven children listed for transplant were studied: cholestatic liver disease (CLDn23); liver disease secondary to other processes (LDsec n11); (IFALDn22), acute liver failure (ALFn11). Paediatric Hepatology Score (PHD) score and Pediatric end-stage liver disease score (PELD) were evaluated by Receiver Operating Curves (ROC), proportional hazards regression. RESULTS The highest PHD and PELD scores were found in ALF; the lowest in LDsec. Both scores correlated well in identifying waiting list (WL) mortality in patients with CLD and ALF, but not in those with IFALD where PELD scores were lower. Cox proportional hazard regression of time spent on the waiting list prior to death or transplant/delisting showed significant associations with PHD (P=0.006) and PELD (P=0.008). WL mortality was strongly predicted by disease group (6/8 deaths in IFALD). ROC analysis of all data showed that a PHD score greater than 15.5 had sensitivity of 87.5% and specificity of 81% for waiting list mortality (P<0.001); PELD greater than 8 had a sensitivity of 87.5% and specificity of 40%. Neither PHD nor PELD scores correlated with post-transplant mortality. CONCLUSION PHD and PELD scores had the same sensitivity for identifying risk of WL mortality in all patients, but PELD failed to identify the sickest children with IFALD, lowering its specificity. The PHD score has the added advantage for European centres of being in SI units, not requiring a computer application to calculate and was simpler to use at bedside.

Abstract
OBJECTIVE Adrenal insufficiency in patients with liver failure, referred to as hepatoadrenal syndrome, is well characterized in adult patients but has not yet been described in children. We present 22 pediatric subjects with end-stage liver disease and adrenal insufficiency, diagnosed using the cosyntropin stimulation test. DESIGN AND SETTING A retrospective chart review using inpatient records from a pediatric intensive care unit in an academic medical center with a busy pediatric transplant program. PATIENTS Most were infants with anatomical short gut and severe, total parenteral nutrition-induced liver failure awaiting liver transplantation. Many were critically ill; 68% required mechanical ventilation and 59% required vasopressors. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS All patients had low baseline cortisol levels and ten also had an abnormal cosyntropin stimulation test. Cortisol levels at baseline and increments of serum cortisol at 30 and 60 mins post cosyntropin were 9.3 ± 5 μg/dL, 9.3 ± 4 μg/dL, and 10.7 ± 6 μg/dL, respectively, compared to these values in five patients with liver failure and normal adrenal function (21.3 ± 3 μg/dL, 10.5 ± 5 μg/dL, and 12.7 ± 3 μg/dL, respectively). Baseline cortisol levels were higher in patients who required vasopressors (11.1 ± 5 μg/dL) compared to those who did not (6.6 ± 4.3 μg/dL, p = .04), and 60-min increment cortisol levels were lower in nonsurvivors compared to survivors (8.6 ± 4.8 μg/dL vs. 15.1 ± 5.1 μg/dL, p = .002). The severity of adrenal insufficiency did not correlate with the degree of hepatic decompensation. Clinical characteristics, including serum electrolytes and vasopressor requirements, were similar in patients with hepatoadrenal syndrome and patients with liver failure and normal adrenal function. Twelve (55%) of the patients died in the hospital, 11 without receiving a transplant. Hydrocortisone therapy permitted rapid weaning of vasopressor therapy but did not affect survival. CONCLUSIONS Children with end-stage liver disease are at risk for hepatoadrenal syndrome and should have their cortisol levels monitored since clinical manifestations may not be diagnostic.

Abstract
OBJECTIVE The purpose of this study was to identify significant, independent factors that predicted 6 month patient and graft survival after pediatric liver transplantation. SUMMARY BACKGROUND DATA The Studies of Pediatric Liver Transplantation (SPLIT) is a multicenter database established in 1995, of currently more than 4000 US and Canadian children undergoing liver transplantation. Previous published analyses from this data have examined specific factors influencing outcome. This study analyzes a comprehensive range of factors that may influence outcome from the time of listing through the peri- and postoperative period. METHODS A total of 42 pre-, peri- and posttransplant variables evaluated in 2982 pediatric recipients of a first liver transplant registered in SPLIT significant at the univariate level were included in multivariate models. RESULTS In the final model combining all baseline and posttransplant events, posttransplant complications had the highest relative risk of death or graft loss. Reoperation for any cause increased the risk for both patient and graft loss by 11 fold and reoperation exclusive of specific complications by 4 fold. Vascular thromboses, bowel perforation, septicemia, and retransplantation, each independently increased the risk of patient and graft loss by 3 to 4 fold. The only baseline factor with a similarly high relative risk for patient and graft loss was recipient in the intensive care unit (ICU) intubated at transplant. A significant center effect was also found but did not change the impact of the highly significant factors already identified. CONCLUSIONS We conclude that the most significant factors predicting patient and graft loss at 6 months in children listed for transplant are posttransplant surgical complications.

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

Abstract
Survival following pediatric re-transplant is inferior to that following primary transplant. We analyzed UNOS data (1987-2007) to identify factors associated with poor outcomes following re-transplant in both the pre-PELD and PELD eras. There may be a combination of factors associated with a futile pediatric liver re-transplant. Identification of these factors may improve allograft allocation and survival following re-transplantation. Abstract: Survival following pediatric liver re-transplant is distinctly inferior to that following primary transplant. The purpose of this study was to determine factors associated with futile pediatric liver re-transplants before and after introduction of the PELD criteria in February 2002. We analyzed the UNOS database (1987-2008) and identified pediatric patients requiring liver re-transplants before and after PELD criteria. Descriptive characteristics were evaluated and survival analyzed with Cox proportional hazards method. Analysis of 1248 children identified re-transplant survival in the PELD era was significantly better than the pre-PELD era. Multivariable analysis in the pre-PELD era identified number of re-transplants, African American race, ICU pretransplant, recipient weight, creatinine and bilirubin levels, donor age, and cold ischemia time to be significantly associated with poor survival. In the PELD era, ICU hospitalization, weight, and very high bilirubin levels were associated with poor survival. Kaplan-Meier analysis by risk groups demonstrated a significant difference in survival, with the highest risk group experiencing 40-50% one-yr survival. Survival following pediatric liver re-transplantation varies significantly by era and associated risk factors. There may be a combination of factors that predict a futile re-transplant. Pre-operative identification of these factors may improve allograft allocation and recipient survival following re-transplantation.

Abstract
Biliary atresia is a rare, serious and challenging disease in newborn children. Its aetiology remains unknown. Optimal management at specialist centres with resultant better overall outcomes is achieved through a multidisciplinary team approach. The Kasai portoenterostomy performed early in life remains the only surgical repair procedure. Two thirds of patients will clear their jaundice after a Kasai procedure, but only about one third will retain their livers after the first decade of life. Failure of this procedure leaves liver transplantation as the only chance for survival, and this disease is the commonest indication for liver transplantation in children. With modern medical care and refinements in surgical techniques, survival after either or both of these procedures is about 90%. Early referral to specialist centres and long-term specialist care remains the key to successful treatment of this condition.

Abstract
AIM The study aimed to assess the outcome of live-donor liver transplantation for pediatric patients in a region with limited access to deceased donors. PATIENTS AND METHODS From September 1993 to September 2008, 78 pediatric patients aged between 73 days and 17 years (mean, 40 months) received 83 liver transplants. Sixty-two were living-related liver transplantations (LRLTs), and 21 were deceased-donor liver transplantations (DDLTs). The mean follow-up period was 6.5 years. The prospectively collected data of these patients were analyzed retrospectively. RESULTS The 1-, 2-, and 5-year survival rates of patients and grafts were 91%, 90%, 88% and 87%, 86%, 83%, respectively. The survival rates of LRLT patients and DDLT patients were 89%, 89%, 87%, and 90%, 86%, 86%, respectively (P = .58). The survival rates of patients aged 12 months or younger and patients older than 12 months were 95%, 92%, 90% and 90%, 90%, 87%, respectively (P = .65). One live donor developed temporary peroneal palsy, and another developed lung collapse (3%, 2/62). All live donors resumed their normal activities with no difficulty. CONCLUSION With meticulous surgical techniques and postoperative care, it is justifiable to accept donated livers from voluntary live donors for transplantation to save pediatric patients in a place with scarce deceased donors.

Abstract
OBJECTIVE(S) Death occurs in half of all children with fulminant hepatic failure (FHF). Although liver transplantation (LT) is potentially life-saving, there are only a few published series with limited experience. The aim was to examine predictors of survival after LT for FHF. METHODS Between 1984 and 2008, all LT for FHF performed in recipients less than or equal to 18 years of age were analyzed from a prospectively maintained database using 35 demographic, laboratory, and operative variables. Unique calculated variables included creatinine clearance (cCrCl) and Pediatric End-Stage Liver Disease score (PELD). Study end-points were patient and death censored graft survival. Median follow-up was 98 months. Statistical analysis involved the log-rank test and Cox proportional hazards model. RESULTS A total of 122 children underwent 159 LTx. Cryptogenic was the primary etiology (70%) and the median age was 53 months. The significant (P < 0.05) univariate predictors of worse graft survival were: recipient age <24 months, cCrCl <60 mL/min/1.73m, PELD >25 points, and warm ischemia time >60 minutes. The significant (P < 0.05) univariate predictors of worse patient survival were: recipient African-American and Asian race, recipient age <24 months, cCrCl <60 mL/min/1.73m, and time from onset jaundice to encephalopathy <7 days. On multivariate analysis, survival was significantly impacted by 4 variables: cCrCl <60 mL/min/1.73m (GRAFT and PATIENT), PELD >25 points (GRAFT), recipient age <24 months (GRAFT), and time from onset jaundice to encephalopathy <7 days (PATIENT). While overall 5- and 10-year survival was 73% and 72% (GRAFT) and 77% and 73% (PATIENT), these were significantly worse when a combination of multivariate risk-factors were present. CONCLUSIONS This data from a large, single-center experience demonstrates that LT is the treatment of choice for FHF and results in durable survival. Analysis revealed 4 novel outcome predictors. Young children with rapid onset acute liver failure are a high-risk subpopulation. Unique to this study, cCrCl and PELD accurately predicted the end-points. This analysis identifies patient subpopulations requiring early aggressive intervention with LT.

Abstract
In previous decades, pediatric liver transplantation has become a state-of-the-art operation with excellent success and limited mortality. Graft and patient survival have continued to improve as a result of improvements in medical, surgical and anesthetic management, organ availability, immunosuppression, and identification and treatment of postoperative complications. The utilization of split-liver grafts and living-related donors has provided more organs for pediatric patients. Newer immunosuppression regimens, including induction therapy, have had a significant impact on graft and patient survival. Future developments of pediatric liver transplantation will deal with long-term follow-up, with prevention of immunosuppression-related complications and promotion of as normal growth as possible. This review describes the state-of-the-art in pediatric liver transplantation.

Abstract
BACKGROUND Kasai portoenterostomy (KP) remains the initial surgical therapy for biliary atresia (BA). Liver transplantation (LTx) is offered after a failed KP or if KP is not feasible. The timing of LTx in these children is not well established. We attempted to define factors that may help choose the optimal timing for LTx in children with BA managed by a multidisciplinary team including a pediatric surgeon, hepatologist, and liver transplant surgeon. METHODS Records of children who underwent LTx for BA at our institution between January 1998 and December 2006 were reviewed. Clinical data such as pre-LTx pediatric end-stage liver disease (PELD) score, location of KP, and outcome were evaluated. RESULTS Seventy one children underwent 77 liver transplants for BA at an average age of 25 months (range, 3-216 months). Sixty-one had a previous KP, 30 at our institution. Ten had LTx without KP. The overall patient survival was 94.4% and overall graft survival was 87% at median follow-up of 58 months (range, 6-111 months). Four patients died, 1 because of vascular thrombosis despite repeat LTx, 1 because of fungal infection after LTx, and 2 because of causes unrelated to LTx. Six children required retransplantation. Living donor liver transplantation was performed in 32 of these children with 91% patient and graft survival. Fifty-three children had a PELD score of 10 or higher with patient and graft survivals of 92% and 86%, respectively. Eighteen children had a PELD score of less than 10 with patient and graft survivals of 100%. For the 30 children who underwent KP at our institution, the median age at LTx was 9 months (range, 3-168 months), and patient and graft survival were both 93%. CONCLUSIONS Outcome of LTx for BA is excellent. Children with higher PELD scores (>/=10) at LTx may have worse outcome. Children with a PELD score of less than 10 survived with their original grafts. In children with BA, the PELD score should be monitored and may help stratify patients for eventual LTx. When a child with BA is deemed a candidate for LTx, the PELD score should be determined. A PELD score that approaches 10 should trigger discussion of LTx and living donor liver transplantation with the family.

Abstract
As the field of Liver Transplantation has matured, survival alone is no longer an acceptable single metric of success. This chapter explores the impact of the PELD system for donor organ allocation, surgical modification of donor organs, living donation, and long-term transplant-related complications on overall quality of life and outcome. Strategies to improve survival, overall outcome, and health-related quality of life in long-term recipients are outlined.

Abstract
BACKGROUND Pediatric liver transplantation (PLTx) is the standard of care for treatment of liver failure in children. Unfortunately, there are few studies with substantial numbers of patients that identify outcomes predictors. The goal of this study was to determine factors that influence outcomes in a large, single-center cohort of PLTx. STUDY DESIGN This retrospective review between 1984 to 2006 included all recipients 18 years of age and younger undergoing PLTx. Multiorgan graft recipients were excluded (n = 48). Data sources included transplantation center database and hospital medical records. Outcomes measures were overall patient and graft survival. Demographic, laboratory, and perioperative variables were analyzed. Univariate and multivariate statistical analysis was undertaken using log-rank test and Cox's proportional hazards model. A p value < 0.05 was considered significant at the multivariate level. RESULTS Eight hundred fifty-two PLTx were performed in 657 children; 55% were girls, 45% were Hispanic, and median age was 29.5 months. Biliary atresia and acute liver failure were the most common causes of liver disease. Fifty-two percent were hospitalized before PLTx. Graft types were whole (75%) and segmental (25%). Indications for re-PLTx (n = 195) included graft nonfunction (22%), immunologic (34%), and vascular complications (35%). Overall 1-, 5-, and 10-year survival rates were 85%, 81%, and 78% (patient), and 78%, 72%, and 67% (graft). Independent significant predictors of worse patient survival were renal function, pretransplantation ventilator dependence, and causes of liver disease. Independent significant predictors of worse graft survival were renal function and warm ischemia time. CONCLUSIONS As one of the largest, single-center analyses of PLTx, this study enables accurate statistical analysis and demonstrates excellent longterm outcomes. Independent prognosticators of graft survival were renal function and warm ischemia time, and those for patient survival were renal function, mechanical ventilation, and causes of liver disease. These factors can aid in the medical decision making required for optimal use of scarce donor organs.

Abstract
Timely access to a living donor (LD) reduced pretransplant mortality in pediatric liver transplantation (LT). We hypothesized that this strategy may provide better posttransplant outcome. Between July 1993 and April 2002, 235 children received a primary LT from a LD (n = 100) or a deceased donor (DD) (n = 135). Demographic, surgical and immunological variables were compared, and respective impact on posttransplant complications was studied using a multivariate analysis. Five-year patient survival rates were 92% and 85% for groups LD and DD, respectively (p = 0.181), the corresponding graft survival rates being 89% and 77% (p = 0.033). At multivariate analysis: (1) type of donor (DD) was correlated with higher rate of artery thrombosis (p < 0.012); (2) biliary complication rate at 5 years was 29% and 23% for groups LD and DD, respectively (p = 0.451); (3) lower acute rejection incidence could be correlated with type of donor (DD) (p = 0.001), and immunosuppressive therapy (tacrolimus) (p < 0.001). We conclude that (1) according to the multivariate analysis, LT with LD provided similar patient and graft outcome, when compared to DD; (2) a higher rate of artery thrombosis and a lower rate of rejection were observed in group DD; (3) this study confirms the efficacy of tacrolimus for immunoprophylaxis, whatever the type of organ donor is.

Abstract
The pediatric end-stage liver disease score (PELD) was devised and validated as a tool for predicting mortality and morbidity in children with chronic liver disease waiting for a liver transplant (LT). It has become a useful guide for prioritizing organ allocation in the United States. The hepatic artery resistance index (HARI) also predicts waiting list mortality in children with biliary atresia. Does the PELD score or HARI predict outcome after LT for biliary atresia? Twenty consecutive children who underwent LT for biliary atresia between 2001 and 2005 were reviewed. Their PELD score was calculated periodically between listing and transplantation and HARI was measured at listing. Outcome variables were operative blood transfusion requirements, ICU stay and postoperative stay. Median age at LT was 8 (2-204) months. After allowing for the type of graft, the PELD score and the change in PELD score between listing and LT (deltaPELD) showed no significant correlation with blood transfusion requirements, but both the PELD score at listing and deltaPELD showed a trend toward a statistically significant positive correlation with overall hospital stay. Pre-transplant HARI showed a statistically significant positive correlation with the PELD score at listing (r = 0.46, p = 0.05) but did not correlate significantly with hospital stay. In this relatively small but homogeneous group of children undergoing LT for biliary atresia, PELD, and deltaPELD scores showed a trend toward a statistically significant positive correlation with overall hospital stay. However, neither PELD scores nor the pre-transplant HARI showed a definite correlation with outcome. Post-transplant complications are probably more important factors determining ICU and hospital stay in children currently transplanted for biliary atresia.

Abstract
Liver transplantation has become the accepted standard of care in the treatment of a child with a failing liver. Advances in the management of critical care and immunosuppression along with the development of innovative operative procedures have improved outcome such that 5-year survival rates of 80% to 90% are expected following liver transplantation. Organ allocation schemes have evolved in an effort to better stratify recipient risk thereby more appropriately distributing deceased donor grafts. A persistent shortage of appropriate donors continues to contribute to patient mortality. The consequences of long-term immunosuppression have become increasingly apparent such that health care providers need to be aware of the side effects of chronic immunosuppression. New strategies need to be defined to minimize the need of continuous immunosuppression. The continued success of pediatric liver transplantation will require multi-disciplinary health care teams comprised of general pediatricians, pediatric hepatologists, transplant surgeons, and transplant coordinators who focus on the complex needs of the transplant recipient.

Abstract
Biliary atresia (BA) is a rare disease characterised by a biliary obstruction of unknown origin that presents in the neonatal period. It is the most frequent surgical cause of cholestatic jaundice in this age group. BA occurs in approximately 1/18,000 live births in Western Europe. In the world, the reported incidence varies from 5/100,000 to 32/100,000 live births, and is highest in Asia and the Pacific region. Females are affected slightly more often than males. The common histopathological picture is one of inflammatory damage to the intra- and extrahepatic bile ducts with sclerosis and narrowing or even obliteration of the biliary tree. Untreated, this condition leads to cirrhosis and death within the first years of life. BA is not known to be a hereditary condition. No primary medical treatment is relevant for the management of BA. Once BA suspected, surgical intervention (Kasai portoenterostomy) should be performed as soon as possible as operations performed early in life is more likely to be successful. Liver transplantation may be needed later if the Kasai operation fails to restore the biliary flow or if cirrhotic complications occur. At present, approximately 90% of BA patients survive and the majority have normal quality of life.

Abstract
In the past two decades, pediatric liver transplantation has become the state-of-the-art operation with anticipated success and limited mortality. The future success of pediatric liver transplantation will require thoughtful solutions to the delicate balance of risk to donors and recipients, the complex needs of the acute postoperative patient, and the long-term challenges of chronic immunosuppression in these previously unsalvageable patients.
