Abstract
BACKGROUND Currently, graft options for pediatric liver transplantation (PLT) include whole (WL) and partial (P) grafts, in the form of either deceased donor transplantation (DD) or living donor liver transplantation (LD). WL transplants from LD are commonly referred to as domino LT. The objective of this manuscript is to compare the outcomes of PLT performed with each of the available graft options. METHODS Retrospective cohort study from Jan. 2010 to Dec. 2022. The variables included data on the recipients' preoperative clinical status, intraoperative technical aspects, post-operative complications, and survival studies. There were 4 groups: SPLIT (17), DD-WL (55), LD-WL (824), and LD-P (22). RESULTS The median age and BW of the recipients was smaller in SPLIT, LD-P, and LD-WL compared to DDT-WL groups. HVOO (HR 15.87, 95% CI 1.89-133.06, P = 0.01), retransplantation (HR 7.94, 95% CI 2.63-24.02, P < 0.01), and malignancies (HR 3.08, 95% CI 1.29-7.37, P = 0.01) were independently associated with decreased patient survival. HAT (HR 27.54, 95% CI 10.44-72.68, P < 0.01) and malignancies (HR 2.42, 95% CI 1.10-5.34, P = 0.03) increased the risk of graft loss. The overall survival in this series was 91.4% (mean follow-up of 74.3 months). Patient and graft survival were not different among groups. CONCLUSION HAT and malignancies were associated with reduced graft survival. Whole liver from living donors with MSUD presented 100% patient survival at 120 months. Even without statistical differences in survival among the studied groups, LD-P and LD-WL recipients presented a trend towards better outcomes. LEVEL OF EVIDENCE LEVEL III.

Abstract
BACKGROUND The techniques involved in neonatal and infantile transplantation require approaches that can sculpt a left lateral segment (LLS) to the right shape and size and avoid large-for-size syndrome. The aim of this article is to describe the anterior hepatic resection (AHR) of the LLS in pediatric LDLT. METHODS A retrospective anatomical study of preoperative image studies, description of the technique for AHR, and short-term results. RESULTS The AHR was performed in eight cases. All donors were male, with average age, BW, and BMI of 28.3 ± 5.9 years, 74.2 ± 9.3 kg, and 24.3 ± 2.6 kg/m2, respectively. Donors were discharged at an average of 3.6 ± 0.8 days. The median recipient age and BW at transplantation were 6.9 (2.7 to 11) months and 5.9 (3.9 to 8) kg, respectively, and the recipient-to-donor body weight ratio (RDBW) was <0.1 in all but one case. The mean percentage reduction in graft weight and in the antero-posterior diameter were 33.2% ± 5.5% and 38.3% ± 12.6%, respectively. The average (SD) GRWR was 4.8% ± 1.7% before all the resections and 3.5% ± 1.0% after the procedures. Seven patients were primarily closed. CONCLUSION After LLS resection, a nonanatomical anterior resection of the LLS was accomplished without hilar vascular dissection to segments II/III. The final liver graft allowed primary abdominal wall closure in all but one patient, with meaningful adjustments in GRWR. AHR proved to be simple, safe, reproducible, and effective in the presented case series.

Abstract
BACKGROUND infants who require liver transplantation represent a treatment challenge because chronic liver disease at this early age affects the child's growth and development during a critical phase. The aim is to compare demographics, operative data, and long-term outcomes according to recipient weight at the time of LDLT. METHODS This retrospective study included primary LDLT analyzed in 2 groups: BW ≤ 7 kg (n = 322) and BW > 7 kg (n = 756). A historical comparison between periods was also investigated. RESULTS BW ≤ 7 kg had significantly lower height/age and weight/age z-scores, with median PELD score of 19. Transfusion rates were higher in the BW ≤ 7 kg group (30.9 ml/kg versus 15.5 ml/kg, P < 0.001). Higher frequencies of PV complications were seen in the BW ≤ 7 kg cohort. HAT and retransplantation rates were similar. Those with BW ≤ 7 kg required longer ICU and hospital stays. Patient and graft survival were similar. Patient survival in BW≤ 7 kg was significantly better in the most recent period. CONCLUSION Malnutrition and advanced liver disease were more frequent in BW ≤ 7 kg. Despite increased rates of PVT and longer hospital stay, patient and graft long-term survival were similar between groups.

Abstract
Pediatric living donor liver transplantation (PLDLT) is a successful therapeutic option for children with chronic and acute liver disease. After early transplant results, many technical advancements were introduced in the field to reduce the rate of complications and improve survival. The aim of this study is to present the outcomes of 975 primary PLDLTs in 3 periods: initial practice (period 1, 29 patients, January 1995 to December 1999), second period (period 2, 331 patients, January 2000 to December 2009), and third period (period 3 [P3], 615 patients, January 2010 to September 2019). Among the technical refinements introduced in P3 are the use of hyperreduced left lateral segment grafts, abdominal wall prosthetic mesh closure, double hepatic artery anastomosis, and increased use of vascular grafts for portal vein reconstruction. The outcomes included significant reductions of hepatic artery thrombosis (HAT), early portal vein thrombosis (EPVT), and retransplantation, with better patient and graft survival in P3. Additional analyses showed that the factors independently associated with worse 90-day patient survival were HAT, EPVT, and increasing Pediatric End-Stage Liver Disease score. In conclusion, the introduction of technical refinements in P3, in addition to improvements in patient care, determined a reduction in EPVT, HAT, and retransplantation. Consequently, patient and graft survival rates increased in all time points studied.

Abstract
Background The microorganism present in breast milk, added to other factors, determine the colonization of infants. The objective of the present study is to evaluate the safety, tolerance and effects of the consumption of a milk formula during the first year of life that is supplemented with L. fermentum CECT5716 or Bifidobacterium breve CECT7263, two strains originally isolated from breast milk. Methods A randomized, double blind, controlled, parallel group study including healthy, formula-fed infants was conducted. Two hundred and thirty-six 1-month-old infants were selected and randomly divided into three study groups according to a randomization list. Infants in the control group received a standard powdered infant formula until 12 months of age. Infants in the probiotic groups received the same infant formula but supplemented with L. fermentum CECT5716 Lc40 or B. breve CECT7263. Main outcome was weigh-gain of infants as safety marker. Results One hundred and eighty-nine infants completed the eleven months of intervention (61 in control group, 65 in Lf group and 63 in Bb group). The growth of infants in the three groups was consistent with standards. No significant differences were observed in the main outcome, weight-gain (Control group: 5.77 Kg ± 0.95, Lf group: 5.77 Kg ± 1.31, Bb group: 5.58 Kg ± 1.10; p = 0.527). The three milk formulae were well tolerated, and no adverse effects were related to the consumption of any of the formula. Infants receiving B. breve CECT7263 had a 1.7 times lower risk of crying than the control group (OR = 0.569, CI 95% 0.568–0.571; p = 0.001). On the other hand, the incidence of diarrhoea in infants receiving the formula supplemented with L. fermentum CECT5716 was a 44% lower than in infants receiving the control formula (p = 0.014). The consumption of this Lactobacillus strain also reduced the duration of diarrhoea by 2.5 days versus control group (p = 0.044). Conclusions The addition of L. fermentum CECT5716 Lc40 or B. breve CECT7263, two probiotic strains naturally found in breast milk, to infant formulae is safe and induces beneficial effects on the health of infants. Trial registration The trial was retrospectively registered in the US Library of Medicine (www.clinicaltrial.gov) with the number NCT03204630. Registered 11 August 2016.

Abstract
CMV infection plays an important role in the postoperative course following solid organ transplantation. We present the case of an 11-year-old male patient who underwent LDLT due to severe hepatopulmonary syndrome and biliary cirrhosis. Four weeks after LDLT, he developed persistent GI bleeding and was subjected to repeated endoscopic treatment and radiological arterial embolization to stop the bleeding from duodenal ulcers. Diagnostic workup was negative for CMV disease. Because the bleeding persisted, surgical treatment was indicated, and a pancreas-preserving duodenectomy was performed. Immunohistochemical staining of the surgical specimen demonstrated diffuse endothelial infiltration by CMV. Despite ganciclovir treatment, the patient developed new erosions in the jejunal mucosa and melena; ganciclovir was discontinued, and foscarnet was started, resulting in clinical improvement and the cessation of bleeding. This case highlights the technical aspects of performing a complex upper GI resection in a patient recently subjected to LDLT, taking care to avoid injury to the previous liver graft anastomosis and restore GI continuity. Moreover, CMV tissue-invasive disease compartmentalized in the GI tract may be difficult to diagnose, as indicated by the negative results of antigenemia and PCR assays and endoscopic superficial mucosal biopsies.

Abstract
Although rare, ALF caused by disseminated HSV infection is associated with high mortality in the neonatal population. This condition is often diagnosed relatively late due to the absence of specific signs. We present a case involving a neonate with ALF submitted to living donor liver transplantation without a prior diagnosis. The patient had no skin or mucosal lesions, and IgM serology was negative for HSV-1 and HSV-2. Immunohistochemical staining of the liver explant was positive for herpes virus infection, and the patient subsequently received antiviral drug treatment, with a good outcome. Due to organ shortages and the rarity of the aforementioned condition, LT has seldom been reported for the treatment of ALF caused by herpes virus infection; however, LT may be the only option for neonates with fulminant hepatitis. The use of living donors in an urgent scenario is well established in Eastern countries and safely applicable for pediatric patients with ALF.

Abstract
BACKGROUND Hepatic artery thrombosis (HAT) increases morbidity and mortality after liver transplantation (LT). The identification of risk factors for HAT may aid transplant teams in the development of strategies aimed at reducing HAT. This article describes the risk factors for HAT and outcomes after LT. METHODS This report describes a retrospective study (1995 to 2015) of primary pediatric living donor LT (LDLT). Pretransplant and technical variables were included in the study. Binary logistic regression was used for data analysis. RESULTS This study included 656 primary LDLT. The median age, body weight, and pediatric end-stage liver disease score at the time of transplant were 13 months, 8.4 kg and 15, respectively. Twenty-one (3.2%) patients developed HAT. Intraoperative HAT (odds ratio, 62.63; 95% confidence interval, 12.64-310.19; P < 0.001) and the use of liver grafts with a graft-to-recipient weight ratio less than 1.1% (odds ratio, 24.46; 95% confidence interval, 4.55-131.56; P < 0.001) retained statistical significance in the multivariate model. Patient and graft survivals were significantly worse in cases with HAT. The overtime trend analysis revealed a decrease in the incidence of HAT (P = 0.008) and an increase in the use of 2-arterial anastomosis (P < 0.001). CONCLUSIONS A graft-to-recipient weight ratio of 1.1% or less and intraoperative HAT were independently associated with HAT. Trend analysis further revealed a significant reduction in the incidence of HAT over time, as well as the increased use of 2 hepatic arteries for anastomosis during graft implantation. The double artery anastomosis may represent an extra protection to pediatric recipients undergoing LDLT.

Abstract
The association between LT and gastrectomy is not common. Only two studies reported the gastrectomy/LT association in children. Here, we report three children who underwent LT who required a concomitant or sequential gastrectomy for different reasons. Patient 1, a 16-yr-old boy, during the LT, underwent a partial gastrectomy due to extensive injury to the duodenum. He had a previous and unusual portoenterostomy performed in the duodenum. Bowel reconstruction was performed using an intestinal loop that was first used for the bilio-enteric anastomosis and then connected to the gastric stump. Patient 2, a 22-month-old female child, underwent a partial gastrectomy with a Roux-en-Y reconstruction during a retransplantation. She had a large perforated gastric ulcer blocked by the allograft liver. Patient 3, a 26-month-old male child, five yr after living donor LT, was submitted to a partial gastrectomy because of gastric outlet obstruction. The histopathology was compatible with eosinophilic gastritis. The association between LT and gastrectomy in the pediatric population is extremely rare. Appropriate knowledge of the previous transplantation technique is very important. Further studies are required to assess the outcomes of the different types of gastric reconstruction in pediatric recipients.

Abstract
Re-LT is the only recourse for patients with liver graft failure. However, survival rates after re-LT are lower than those of primary transplants. Few reports are available regarding re-LT with LDs in children. The objective of this study was to describe our cohort of patients retransplanted with LD and emphasize the technical aspects of a re-LT with LD. This is a retrospective report of a series of 18 children (<18 yr old) submitted to 20 re-LT from January 1997 to December 2013 at Hospital Sirio-Libanes and Hospital AC Camargo Cancer Center. The one- and five-yr survival for patients retransplanted with LD was 70.6% and 58.6%. Little technical modifications from a regular LD primary transplant were needed in patients retransplanted with LD. Seven (38.8%) patients presented vascular complications following re-LT and three presented biliary complications (16.6%). In conclusion, a re-LT with LD is an acceptable alternative for children who experience liver graft failure and it does not compromise the donor pool. Further experience with re-LT with LD may support this therapy.

Abstract
Biliary atresia (BA) is the main diagnosis leading to liver transplantation (LT) in children. When diagnosed early in life, a Kasai portoenterostomy (Kasai-PE) can prevent or postpone LT. Instances of previous operations can result in difficulties during the LT. We hypothesized that a previous Kasai-PE could affect LT outcomes. A retrospective cohort study of 347 BA patients submitted to LT between 1995 and 2013 at Hospital Sírio-Libanês and A. C. Camargo Cancer Center was conducted. Patients were divided into those with a previous Kasai portoenterostomy early failure (K-EF), Kasai portoenterostomy late failure (K-LF), and those with no Kasai portoenterostomy (No-K). Primary outcomes were patient and graft survival. A total of 94 (27.1%) patients had a K-EF, 115 (33.1%) had a K-LF, and 138 (39.8%) had No-K before LT. Children in the K-LF group were older and had lower Pediatric End-Stage Liver Disease (PELD) scores. Patients in both K-EF and K-LF groups had more post-LT biliary complications. After Cox-multivariate analysis adjusting for confounding factors to determine the influence of Kasai-PE on patient and graft survival, the K-LF group had an 84% less probability of dying and a 55% less chance to undergo retransplantation. The K-LF group had a protective effect on posttransplant patient and graft survival. When properly performed, the Kasai procedure can postpone LT and positively affect outcomes. Having a K-EF and having not performed a Kasai-PE had the same effect in patient and graft survival; however, a previous Kasai-PE can increase post-LT complications as biliary complications and bowel perforations.

Abstract
The technique of vascular reconstruction plays a major role in the outcome of living donor liver transplantation (LDLT). An increased use of vascular grafts (VGs) as replacements for sclerotic portal veins has become a standard technique for our group. The aim of this study was to analyze the factors associated with portal vein thrombosis (PVT) in pediatric LDLT. We performed a retrospective analysis of 486 primary pediatric LDLT procedures performed between October 1995 and May 2013. VGs used for portal reconstruction included living donor inferior mesenteric veins, living donor ovarian veins, recipient internal jugular veins, deceased donor iliac arteries, and deceased donor iliac veins. Thirty-four patients (7.0%) developed PVT. The incidence of PVT dropped from 10.1% to 2%; the overall utilization of VGs increased from 3.5% to 37.1%. In a multivariate analysis, only the use of VGs remained an independent risk factor for the occurrence of PVT (hazard ratio = 7.2, 95% confidence interval = 2.8-18.7, P < 0.001). There was no difference in survival rates between patients with PVT and patients without PVT. No patient with PVT underwent retransplantation. In conclusion, the use of VGs was independently associated with the development of PVT. Over time, there was a reduction in the incidence of early PVT in this cohort, and there was a trend toward a reduction in total PVT. The occurrence of isolated PVT in this study was not associated with decreased patient or graft survival.

Abstract
The increasing number of transplants performed each year has led to the identification of unusual diseases in liver grafts from asymptomatic donors that were unrecognized before liver transplantation. Here we report our experience with patients who received liver grafts infected with schistosomiasis. From September 1991 to August 2010, 482 pediatric liver transplants were performed at A. C. Camargo Hospital/Sírio-Libanês Hospital (São Paulo, Brazil). For the identification of Schistosoma mansoni infections, pathology slides for the recipients were reviewed; these included postreperfusion and follow-up liver biopsy samples. We were able to identify 6 cases of schistosomiasis transmitted through infected grafts (5 of these grafts were from living donors). All living donors were confirmed to have normal liver chemistries, negative fecal tests for parasitic diseases, and normal abdominal ultrasound findings. Liver biopsy was not performed before transplantation. In all cases, features of schistosomiasis were absent in the liver explants. The living donors were treated with praziquantel and were taught to avoid risk factors for reinfection. No specific treatment for schistosomiasis was given to the recipients. There were no perioperative deaths, but 2 recipients died after living donor liver transplantation (LDLT) because of Kaposi's sarcoma and non-Hodgkin's lymphoma. In conclusion, using liver grafts infected with S. mansoni eggs did not compromise the results of LDLT in this pediatric cohort. Because of the parasite's life cycle and the therapeutic target of praziquantel, only donors should be treated for the infection. Three years of follow-up showed an uneventful recovery for the living donors.
