Abstract
INTRODUCTION Adjusting immunosuppression to minimal levels post-adult liver transplantation (LT) is critical; however, graft rejection has been reported in LT recipients with normal liver function evaluated by liver biopsy (LBx). Continual protocol liver biopsy (PLB) is performed regularly in LT recipients with normal liver function in some centers; however, its usefulness remains inadequately evaluated. This study aimed to assess retrospectively the usefulness of late PLB after adult LT. METHODS LBx evaluations of LT recipients with normal liver function and hepatitis B and C virus seronegativity were defined as PLB. The cases requiring immunosuppressive therapy for rejection findings based on Banff criteria were extracted from the PLBs, and pathological data collected before and after immunosuppressive dosage adjustment (based on modified histological activity index [HAI] score) were compared. RESULTS Among 548 LBx cases, 213 LBx in 110 recipients fulfilled the inclusion criteria for PLB. Immunosuppressive therapy after PLB was intensified in 14 LBx (6.6%) recipients (12.7%); of these, nine had late-onset acute rejection, three had isolated perivenular inflammation, one had plasma cell-rich rejection, and one had early chronic rejection. Follow-up LBx after immunosuppressive dose adjustment showed improvement in the modified HAI score grading in 10 of 14 cases (71.4%). No clinical background and blood examination data, including those from the post-LT period, immunosuppressant trough level, or examination for de novo DSA, predicted rejection in PLB. Complications of PLB were found in only three cases. CONCLUSION PLB is useful in the management of seemingly stable LT recipients, to discover subclinical rejection and allow for appropriate immunosuppressant dose adjustment.

Transplantation: Incidence, Time of Detection, and Positive Predictive
Value. Ultrasound Int Open 2022; 8:E36-E42. [PMID: 36408371 PMCID: PMC9668490 DOI: 10.1055/a-1961-9100] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 10/13/2022] [Indexed: 11/18/2022] Open
Abstract
Purpose
Doppler ultrasound (DUS) is widely used to detect vascular
complications after pediatric liver transplantation (LT). This study aimed to
assess the moment of first detection of vascular complications with DUS, and to
determine the positive predictive value (PPV) of DUS.
Materials and Methods
Patients aged 0–18 years who underwent LT
between 2015 and 2019 were retrospectively included. 92 LTs in 83 patients were
included (median age: 3.9 years, interquartile range: 0.7–10.5).
Patients underwent perioperative (intra-operative and immediately postoperative)
and daily DUS surveillance during the first postoperative week, and at 1, 3, and
12 months. Vascular complications were categorized for the hepatic artery,
portal vein, and hepatic veins. DUS findings were compared to surgical or
radiological findings during the 1-year follow-up.
Results
52 vascular complications were diagnosed by DUS in 35/92
LTs (38%). 15 out of 52 (28.8%) were diagnosed perioperatively,
29/52 (55.8%) were diagnosed on postoperative days 1–7,
and 8/52 (15.4%) after day 7. The PPV for all vascular
complications diagnosed with DUS was 92.3%. During the 1-year follow-up,
18/19 (94.7%) hepatic artery complications, 19/26
(73.1%) portal vein complications, and 7/7 (100%)
hepatic vein complications were diagnosed perioperatively or during the first
week.
Conclusion
The majority of vascular complications during the first year
after pediatric LT were diagnosed by DUS perioperatively or during the first
week, with a high PPV. Our findings provide important information regarding when
to expect different types of vascular complications on DUS, which might improve
DUS post-LT surveillance protocols.

Abstract
Background Nowadays, pediatric liver transplantation (PLT) has become an effective strategy for treating various acute or chronic end-stage liver diseases and inherited metabolic diseases. Many experts have already concluded the current challenges and future directions of PLT. However, no detailed analysis of the publication landscape has substantiated these proposed opinions. Methods This study presents a bibliometric review of the articles related to PLT between 1997 and 2020. A total of 3,084 publications were analyzed mainly by CiteSpace and VOSviewer. Results The field of PLT has evolved gradually in the past two decades. Articles increased at an average rate of 97 articles every 4 years. University of Pittsburgh (PITT) is the most prolific institution. The three most productive regions are North America, Europe, and East Asia. Currently, interdisciplinary studies on PLT are scarce. The main goal of PLT has shifted from survival rates to long-term outcome. The quality of life, living donor liver transplantation (LDLT), immunological biomarkers, perioperative hemodynamic management, expanding the indications of PLT, etc. are parts of the emerging research fronts. In the past two decades, articles that contain potentials that may lead to transformative discoveries are scarce, and obvious deficits can be seen in the field of new therapies. Conclusions Long-term outcome and good quality of life represent the principal direction of work concerning PLT. Deficits in new therapies align with the shortage of intellectual milestones, which indicate possible subsequent intellectual milestones may occur as innovations in therapies such as new immunosuppression therapies or liver cell transplantation.

Two-Dimensional Shear Wave Elastography Evaluation of Post-transplantation Complications in Pediatric Receipt: A Retrospective Cohort. Front Pediatr 2022; 10:918145.

Abstract
BACKGROUND The 20-year survival rate in pediatric patients after liver transplantation (LT) was no more than 70%. Hepatic fibrosis is one of the principal factors affecting the long-term prognosis. Imaging evaluation was the first-line examination for pediatric liver graft assessment. However, the sensitivity and specificity were insufficient. Thus, two-dimensional shear wave elastography (2D-SWE) was performed to evaluate liver graft stiffness and complication in post-transplant pediatric receipt. MATERIALS AND METHODS In this retrospective cohort, 343 pediatric recipients who underwent liver graft biopsy in our tertiary LT center were recruited between June 2018 and December 2020. The 2D-SWE evaluation, laboratory examination, routine post-transplant biopsy, and hepatic pathological assessment were performed. RESULTS Ninety-eight of the 343 pediatric patients were included according to the protocol. The Liver Stiffness Measurements (LSM) value of 2D-SWE was significantly elevated in post-transplant fibrosis (p < 0.0001). The LSM value of patients with post-transplant biliary complications (p < 0.0001) and biopsy-proven rejection (BPR, p = 0.0016) also rose compared to regular recovery patients. Concerning the sensitivity and specificity of 2D-SWE in diagnosing liver graft fibrosis, the area under the ROC curve (AUC) was 88%, and the optimal cutoff value was 10.3 kPa. CONCLUSION Pediatric LSM by 2D-SWE was efficient. Routine 2D-SWE evaluation could be optimal to predict significant liver graft fibrosis.

Recipient-Specific Risk Factors Impairing Patient and Graft Outcome after Pediatric Liver Transplantation-Analysis of 858 Transplantations in 38 Years. CHILDREN-BASEL 2021; 8:children8080641. [PMID: 34438532 PMCID: PMC8393592 DOI: 10.3390/children8080641] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 07/19/2021] [Accepted: 07/22/2021] [Indexed: 12/19/2022]
Abstract
(1) Background and Aim: Despite excellent long-term results in pediatric liver transplantation (pLTx), mortality and graft loss still are to be diminished. We aim to describe time-dependent changes and long-term outcome of a large single-center pLTx cohort and to identify independent recipient-related risk factors impairing patient and graft survival. (2) Methods: This is a retrospective single-center study analyzing all pediatric liver transplants from 1983–2020. Risk factors for mortality and graft loss were identified by univariable and multi-linear regression analysis. (3) Results: We analyzed 858 liver transplantations in 705 pediatric patients. Five-year patient/graft survival increased from 60.9%/48.0% (1983–1992) to 97.5%/86.5% (OR = 12.5; p < 0.0001/OR = 6.5; p < 0.0001) (2014–2020). Indications changed significantly over time, with a higher proportion of patients being transplanted for malignancies and metabolic disease and indications of PFIC and α1AT-deficiency declining. The era of transplantation (log7.378/9.657; p < 0.0001) and indication of acute liver failure (log = 1.944/2.667; HR = 2.015/1.772; p = 0.0114/0.002) impairs patient/graft survival significantly in the multivariate analysis. Furthermore, patient survival is worsened by re-transplantation (log = 1.755; HR = 1.744; p = 0.0176) and prolonged waiting times in high-urgency status (log = 2.588; HR = 1.073; p = 0.0026), whereas the indication of biliary atresia improved outcome (log = 1.502; HR = 0.575; p = 0.0315). Graft survival was additionally impaired by pre-existing portal vein thrombosis (log = 1.482; HR = 2.016; p = 0.0330). (4) Conclusions: Despite more complex indications, patient and graft survival after pLTx continue to improve.. Acute liver failure remains the indication with poorest outcome, and listing for high urgency liver transplantation should be considered carefully and early to keep waiting time on HU list short. Furthermore, pre-transplant portal vein thrombosis should be prevented whenever possible to improve graft survival.

Abstract
We aimed to assess executive functioning in children after liver transplantation compared with healthy controls and in relation to real-life school performance using the PedsQLTM Cognitive Functioning Scale (CogPedsQL) and the Childrens’ Color Trail Test (CCTT). One hundred and fifty five children (78f, median age 10.4 (1.2–18.3) years) underwent testing with CogPedsQL and/or CCTT 4.9 (0.1–17.0) years after transplantation. Results were compared to those of 296 healthy children (165f, median age 10.0 (2.0–18.0) years). Liver transplanted children displayed significantly reduced scores for cogPedsQL and CCTT1&2 compared to healthy controls. Overall, school performance was lower in patients compared to controls. In both patients and controls, results of CCTT2 and CogPedsQL correlated strongly with school performance. In contrast to controls, school performance in patients correlated with the level of maternal but not paternal primary education degree (r = −0.21, p = 0.03). None of the patient CCTT or CogPedsQL test results correlated with parental school education. Conclusion: CogPedsQL and CCTT 1&2 were easily applicable in children after OLT and revealed reduced executive functioning compared to controls. Results reflect real life school performance. The association of parental education with school performance is reduced in transplanted children, which possibly indicates the overriding impact of transplant-associated morbidity on cognitive outcomes.

Low-dose steroids do make a difference: Independent risk factors for impaired linear growth after pediatric liver transplantation. Pediatr Transplant 2021; 25:e13989.

Abstract
Growth failure persists after pediatric liver transplantation and impairs pediatric development and quality of life. Steroid dose minimization attempts to prevent growth impairment, yet long-term assessment in pediatric liver recipients is lacking. We identified risk factors for impaired linear growth after pediatric liver transplantation, with a special focus on low-dose steroid therapy. This is a single-center retrospective analysis of height development in pediatric liver recipients up to 5 years after transplantation. Risk factors for impaired linear growth (height Z-scores≤-2) at transplantation, after two (n = 347) and five years (n = 210) were identified by univariate and multivariate logistic regression. At transplantation, growth retardation was found in 52.2%, predominantly younger children. Height Z-scores improved from -2.23 to -1.40 (SE 0.11; 95%CI 0.74-1.16; p < .001) two years and -1.19 (SE 0.07;0.08-0.34; p = .017) five years post-transplant. Multivariate analysis showed previous growth impairment (OR=1.484; 95%-CI=1.107-1.988; p = .004), graft loss (49.006;2.232-1076; p = .006), and prolonged cold ischemic time (1.034;1.007-1.061; p = .011) as main long-term risk factors; steroid use was a significant predictor of 2-year but not 5-year growth impairment. In univariate analysis, impaired growth after 2 and 5 years was associated with continuous low-dose (2.5 mg/m2 BSA) steroid therapy (OR=3.323;1.578-6.996; p < .001/OR=8.352;1.089-64.07; p = .006)and graft loss (OR=2.513;1.395-4.525; p = .003/OR=3.378;1.815-7.576; p < .001). Furthermore, indication and era of transplantation affected growth. Our results show significant catch-up growth after pediatric liver transplantation, yet growth failure strongly affects particularly young liver recipients. The main influenceable long-term risk factor is pre-existing growth failure, emphasizing the importance of early aggressive nutritional therapy. Moreover, low-dose steroid therapy might impair growth and should therefore be critically questioned in long-term immunosuppression.

Abstract
Liver transplantation is the standard treatment for children with end-stage liver disease, primary hepatic neoplasms, or liver-localized metabolic defects. Perioperative mortality is almost absent, and long-term survival exceeds 90%. Organ shortage is managed thanks to advances in organ retrieval techniques; living donation and partial liver transplantation almost eliminated waiting list mortality, thus leading to expanding indications for transplantation. The success of pediatric liver transplantation depends on the prompt and early referral of patients to transplant Centers and on the close and integrated multidisciplinary collaboration between pediatricians, hepatologists, surgeons, intensivists, oncologists, pathologists, coordinating nurses, psychologists, and social workers.

Abstract
Genetic alterations in PEX genes lead to peroxisome biogenesis disorder. In humans, they are associated with Zellweger spectrum disorders (ZSD). No validated treatment has been shown to modify the dismal natural history of ZSD. Liver transplantation (LT) improved clinical and biochemical outcomes in mild ZSD patients. Hepatocyte transplantation (HT), developed to overcome LT limitations, was performed in a mild ZSD 4-year-old child with encouraging short-term results. Here, we evaluated low dose (12.5 million hepatocytes/kg) and high dose (50 million hepatocytes/kg) syngeneic male HT via intrasplenic infusion in the Pex1-G844D NMRI mouse model which recapitulates a mild ZSD phenotype. HT was feasible and safe in growth retarded ZSD mice. Clinical (weight and food intake) and biochemical parameters (very long-chain fatty acids, abnormal bile acids, etc.) were in accordance with ZSD phenotype but they were not robustly modified by HT. As expected, one third of the infused cells were detected in the liver 24 h post-HT. No liver nor spleen microchimerism was detected after 7, 14 and 30 days. Future optimizations are required to improve hepatocyte engraftment in Pex1-G844D NMRI mouse liver. The mouse model exhibited the robustness required for ZSD liver-targeted therapies evaluation.

Abstract
Liver transplantation has become the standard of care for children with end-stage liver disease. In Australia and New Zealand, there are four paediatric liver transplant units, in Sydney, Melbourne, Brisbane and Auckland. Over the past 30 years, there have been significant changes to indications for transplant, as well as medical and surgical advances. In this paper, using retrospective data from the Australia and New Zealand Liver Transplant Registry, we review 977 children (less than 16 years of age) who underwent liver transplant from 1985 to 2018. The most common indication was biliary atresia (54%), although there has been an increase in other indications, including inborn errors of metabolism, fulminant hepatic failure and malignant liver tumours. Over the past 3 decades, areas of change and innovation include: the use of 'split grafts' to enable an adult and a child to receive the same donor liver, live donation, improvements in immunosuppressive regimens and infectious prophylaxis protocols and innovative surgical techniques allowing transplantation in smaller infants. The outcomes for children who undergo liver transplant in ANZ are excellent, with current 10-year patient survival rates of 95%, comparable to other larger centres around the world.

Abstract
Background: This retrospective study aimed to evaluate overall survival and the risk factors for mortality among Korean pediatric liver transplantation (LT) patients using data from two national registries: the Korean Network Organ Sharing (KONOS) of the Korea Centers for Disease Control and Prevention and the Korean Organ Transplantation Registry (KOTRY). Methods: Prospectively collected data of 755 pediatric patients who underwent primary LT (KONOS, February 2000 to December 2015; KOTRY, May 2014 to December 2017) were retrospectively reviewed. Results: The 1-, 5-, 10-, and 15-year survival rates were 90.6%, 86.7%, 85.8%, and 85.5%, respectively, in KONOS, and the 1-month, 3-month, 1-year, and 2-year survival rates were 92.1%, 89.4%, 89.4%, and 87.2%, respectively, in KOTRY. There was no significant difference in survival between the two registries. Multivariate analysis identified that body weight ≥6 kg (p <0.001), biliary atresia as underlying liver disease (p = 0.001), and high-volume center (p < 0.001) were associated with better survival according to the KONOS database, while hepatic artery complication (p < 0.001) was associated with poorer overall survival rates according to the KOTRY database. Conclusion: Long-term pediatric patient survival after LT was satisfactory in this Korean national registry analysis. However, children with risk factors for poor outcomes should be carefully managed after LT.

Abstract
BACKGROUND Pediatric living donor liver transplantation (LDLT) has become the gold standard for patients with end-stage liver disease. With improvements in organ preservation, immunosuppression, surgical and anesthesia techniques, the survival rates and long-term outcomes of patients after LDLT have significantly improved worldwide. However, data on anesthetic management and postoperative survival rate of pediatric LDLT in China are rare.
AIM To review the status of pediatric LDLT in Shanghai and investigate the factors related to anesthetic management and survival rate in pediatric LDLT.
METHODS We conducted a retrospective observational study to investigate the status of pediatric LDLT in Shanghai by reviewing 544 records of patients who underwent pediatric LDLT since the first operation on October 21, 2006 until August 10, 2016 at Renji Hospital and Huashan Hospital.
RESULTS The 30-d, 90-d, 1-year, and 2-year survival rates were 95.22%, 93.38%, 91.36%, and 89.34%, respectively. The 2-year patient survival rate after January 1, 2011 significantly improved compared with the previous period (74.47% vs 90.74%; hazard ratio: 2.92; 95% confidence interval (CI): 2.16–14.14; P = 0.0004). Median duration of mechanical ventilation in the intensive care unit (ICU) was 18 h [interquartile range (IQR), 15.25–20.25], median ICU length of stay was 6 d (IQR: 4.80–9.00), and median postoperative length of stay was 24 d (IQR: 18.00–34.00). Forty-seven (8.60%) of 544 patients did not receive red blood cell transfusion during the operation.
CONCLUSION Pediatric end-stage liver disease (PELD) score, anesthesia duration, operation duration, intraoperative blood loss, and ICU length of stay were independent predictive factors of in-hospital patient survival. Pediatric end-stage liver disease score, operation duration, and ICU length of stay were independent predictive factors of 1-year and 3-year patient survival.

Abstract
BACKGROUND Observed long-term outcomes no longer reflect the survival trajectory facing pediatric liver transplant (LT) recipients today. We aimed to use national registry data and parametric models to project 20- and 30-year post-transplant outcomes for recently transplanted pediatric LT recipients. METHODS We conducted a retrospective cohort study of 13,442 first-time pediatric (age <18) LT recipients using 1987 to 2018 Scientific Registry of Transplant Recipients data. We validated the proposed method (ie, to project long-term patient and graft survival using parametric survival models and short-term data) in 2 historic cohorts (1987-1996 and 1997-2006) and estimated long-term projections among patients transplanted between 2007 and 2018. Projections were stratified by raft type, recipient age, and indication for transplant. RESULTS Parsimonious parametric models with Weibull distribution can be applied to post-transplant data and used to project long-term outcomes for pediatric LT recipients beyond observed data. Projected 20-year patient survival for pediatric LT recipients transplanted in 2007 to 2018 was 84.0% (95% confidence interval 81.5-85.8), compared to observed 20-year survival of 72.8% and 63.6% among those transplanted in 1997 to 2006 and 1987 to 1996, respectively. Projected 30-year survival for pediatric LT recipients in 2007 to 2018 was 80.1% (75.2-82.7), compared to projected 30-year survival of 68.6% (66.1-70.9) in the 1997 to 2006 cohort and observed 30-year survival of 57.5% in the 1987 to 1996 cohort. Twenty- and 30-year patient and graft survival varied slightly by recipient age, graft type, and indication for transplant. CONCLUSIONS Projected long-term outcomes for recently transplanted pediatric LT recipients are excellent, reflective of substantial improvements in medical care, and informative for physician-patient education and decision making in the current era.

Abstract
Tacrolimus is the cornerstone in pediatric liver transplant immunosuppression. Despite close monitoring, fluctuations in tacrolimus blood levels affect safety and efficacy of immunosuppressive treatments. Identifying the factors related to the variability in tacrolimus exposure may be helpful in tailoring the dose. The aim of the present study was to characterize the clinical, pharmacological, and genetic variables associated with systemic tacrolimus exposure in pediatric liver transplant patients. De novo transplant patients with a survival of more than 1 month were considered for inclusion and were genotyped for cytochrome P450 3A5 (CYP3A5). Peritransplant clinical factors and laboratory covariates were recorded retrospectively between 1 month and 2 years after transplant, including alanine aminotransferase (ALT), aspartate aminotransferase, hematocrit, and tacrolimus predose steady-state blood concentrations collected 12 hours after tacrolimus dosing. A linear mixed effect (LME) model was used to assess the association of these factors and the log-transformed tacrolimus dose-normalized trough concentration (logC0/D) levels. Bootstrapping was used to internally validate the final model. External validation was performed in an independent group of patients who matched the original population. The developed LME model described that logC0/D increases with increases in time after transplant (β = 0.019, 95% confidence interval [CI], 0.010-0.028) and ALT values (β = 0.00030, 95% CI, 0.00002-0.00056), whereas logC0/D is significantly lower in graft CYP3A5 expressers compared with nonexpressers (β = -0.349, 95% CI, -0.631 to -0.062). In conclusion, donor CYP3A5 genotype, time after transplant, and ALT values are associated with tacrolimus disposition between 1 month and 2 years after transplant. A better understanding of tacrolimus exposure is essential to minimize the occurrence of an out-of-range therapeutic window that may lead to adverse drug reactions or acute rejection.

Abstract
Indications for liver transplantation have expanded over the past few decades owing to improved outcomes and better understanding of underlying pathologies. In particular, there has been a growing interest in the field of transplant oncology in recent years that has led to considerable developments which have pushed the boundaries of malignant indications for liver transplantation beyond hepatocellular carcinoma (HCC). In this article, we review and summarise the published evidence for liver transplantation in non-HCC primary and metastatic liver malignancies and highlight ongoing clinical trials that address unresolved questions therein. We also examine the current technical, immunological and oncological challenges that face liver transplantation in this growing field and explore potential approaches to overcome these barriers.

Abstract
Background Neurocognitive dysfunction commonly occurs after solid organ transplantation and affects 15–30% of liver transplant recipients. The aim of this study was to evaluate the neurocognitive changes pre- and post-operation and the relative factors affecting those changes. Material/Methods Children with biliary atresia who underwent pediatric living donor-related liver transplantation before the age of 2 years were given Bayley Scale of Infant Development-II test (BSID-II), including Mental Development Index (MDI) and Psychomotor Development Index (PDI) the week before and again half a year after transplantation to assess the effect of transplantation on neurocognition. According to the test outcome, the children were divided into a normal group and an abnormal group. The association of clinical data with neurocognitive development between the 2 groups was analyzed by logistic regression analysis. Results There was a certain degree of improvement in neurocognition half a year after surgery compared with preoperative. The BSID-II subscales were significantly lower than expected before and after transplantation. Preoperative blood ammonia and bilirubin levels were independent risk factors for MDI half a year after transplantation, and preoperative albumin and bilirubin levels were risk factors for PDI. Conclusions Liver transplantation clearly improves children’s neurocognitive function. The postoperative neurocognition is closely related to pre-operation nutritional development.

Abstract
The aim of the study was to investigate the occurrence of fatigue in 100 pediatric liver transplant recipients aged 2-18 years and its impact on their health-related quality of life (HRQL). HRQL and fatigue were measured using the PedsQL 4.0 Inventory and the PedsQL Multidimensional Fatigue Scale, which encompasses three subscales: general fatigue, sleep/rest fatigue, and cognitive fatigue. The impact of the different domains of fatigue and of clinical and sociodemographic factors on the HRQL was identified with stepwise multiple regression analyses. Parent proxy-reports were available for all 100 participants (2-18 years), and child self-reports were available for 71 patients (8-18 years). Across all domains, participants and their parents reported significantly more fatigue than healthy peers in a large PedsQL validation study. Thirty-seven percent of patients and 57% of parents scored clinically relevant levels of fatigue. In the multiple regression analyses, none of the clinical and sociodemographic factors contributed to the HRQL for child self-report. Only general and cognitive fatigue were significant predictors of patients' HRQL, explaining 66% of the variance in the PedsQL total score. For parent proxy-report, general and cognitive fatigue also significantly predicted child's HRQL. Further predictors were child's age and family income. The regression model explained 65% of the variance. These findings demonstrate the importance of assessing fatigue during regular follow-up examinations. Further research is urgently needed to better understand the underlying mechanisms of fatigue. Improvement of fatigue symptoms is essential for better HRQL, for cognitive functioning, and for school achievement.

Abstract
Vascular complications are a major cause of patient and graft loss after LTs. The aim of this study was to evaluate the effect of a multimodal perioperative strategy aimed at reducing the incidence of vascular complications. A total of 126 first isolated LTs-performed between November 2008 and December 2015-were retrospectively analyzed. A minimum follow-up period of 24 months was analyzable for 124/126 patients (98.4%). The aggressive preemptive strategy consisted of identifying and immediately managing any problem and any abnormality in the vascular flow, in any of the hepatic vessels, and at any time after the liver graft revascularization. As a result, with a median follow-up of 57 months (3-112 months), not a single graft has been lost from vascular or biliary problems. The actuarial 8-year graft survival is 96.5%. These results have shown that a combination of technical attention, medical prevention, an early diagnosis, and rapid interventions reduced the negative impact of vascular problems on the outcome of both grafts and patients.

Abstract
Liver transplant is considered to be the last-resort treatment approach for pediatric patients with end-stage liver disease. Despite the remarkable advance in survival rates, liver transplant remains an intricate surgery with significant morbidity and mortality. Early diagnosis of complications is crucial for patient survival but is challenging given the lack of specificity in clinical presentation. Knowledge of the liver and vascular anatomy of the donor and the recipient or recipients before surgery is also important to avoid complications. In this framework, radiologists play a pivotal role on the multidisciplinary team in both pre- and postoperative scenarios by providing a road map to guide the surgery and by assisting in diagnosis of complications. The most common complications after liver transplant are (a) vascular, including the hepatic artery, portal vein, hepatic veins, and inferior vena cava; (b) biliary; (c) parenchymal; (d) perihepatic; and (e) neoplastic. The authors review surgical techniques, the role of each imaging modality, normal posttransplant imaging features, types of complications after liver transplant, and information required in the radiology report that is critical to patient care. They present an algorithm for an imaging approach for pediatric patients after liver transplant and describe key points that should be included in radiologic reports in the pre- and postoperative settings.

Abstract
The published paediatric experience with endoscopic retrograde cholangio-pancreatography (ERCP) in the diagnosis and management of biliary complications following liver transplantation (LT) is limited. We describe our experience with ERCP in the management of children following LT who presented with biliary complications, over a 20-year period (1995-2014). The retrospectively reviewed data are summarized descriptively. Of 94 children (47 boys) who received 102 liver transplants at our centre, seven children (five boys, two girls) underwent ERCP after liver transplantation. In total, 25 ERCP procedures were carried out in these patients. The median age at liver transplantation was 10.7 (3.9-16.2) years. The median interval between LT and the first ERCP was 28 days (12 days-6.8 years). All patients were on standard calcineurin-inhibitor-based immunosuppression regimens. Six of the seven patients underwent ERCP on more than one occasion [median number of ERCP sessions per patient- 4, (1-6)]. Seventeen procedures were carried out under conscious sedation, remaining eight under general anaesthesia. Sedation was achieved employing a standard regimen (Midazolam 5 mg with Pethidine 50 mg) and occasionally Fentanyl. ERCP is an effective and safe intervention from both diagnostic and therapeutic point of view, in the management of post-LT biliary complications in children.

Pediatric Surgery remains the only true General Surgery. Porto Biomed J 2017; 2:143-144.

Abstract
This article states that Pediatric Surgery remains probably the only remaining General Surgery because it is not about organs and systems but rather the whole Surgery from fetal life until completion of growth and maturation. Pediatric surgeons are currently involved in prenatal treatments for fetal diseases, they take in charge the surgery of congenital malformations, acquired neonatal diseases, common conditions like hernias, undescended testes and appendicitis, but also of the more complex gastrointestinal, broncho-pulmonary or genitourinary conditions, tumors, trauma and solid organ transplantation. For this, like other surgical specialists, they use open, endoscopic and minimally invasive techniques. The broad spectrum of diseases, many of them scarcely prevalent, makes training long and hard, but this challenge accounts for the greatness of this specialty. Pediatric surgeons also carry out research work in their field because they are aware that understanding of why the conditions treated by them occur is mandatory. In summary, Pediatric Surgery is a lively, exciting, difficult specialty that offers an attractive alternative to young doctors interested in surgery.

Abstract
AEs during immunosuppressive treatment with tacrolimus are very common. We retrospectively evaluated FK safety and efficacy in a large pediatric liver transplant cohort in Latin America. During 2-year follow-up, we analyzed data from patients who underwent liver transplantation over the period 2010-2012 and recorded FK exposure, AEs, and AR episodes. AEs were classified according causality and severity. Tacrolimus exposure before and during AE was compared using Wilcoxon matched-pairs test. Kaplan-Meier curves were used for survival analysis. In total, 46 patients (out of 72 patients) experienced 69 AEs, such as hypomagnesemia (49%), PTLD (6%), hypertension (6%), and/or nephrotoxicity (22%). 43% of AEs were classified as moderate or serious, and 89% were assigned as probable or definitive. Patients who had one or more AR episodes accounted for 65%. The 12-month acute rejection-free survival was 41% (95% CI, 30.1%-53.1%). A significant difference was observed in FK trough concentrations before and during hypomagnesemia and nephrotoxicity (P<.05). This study is the first report of FK safety in a large group of pediatric liver transplant patients in Latin America. Children experience AEs, even in protocols with low FK doses. Therapeutic monitoring is an important tool to manage immunosuppressive schemes containing tacrolimus in vulnerable populations.
