Sinusoidal obstruction syndrome (SOS) is a potentially fatal complication of hematopoietic stem cell transplantation (HSCT). Traditional ultrasound (US) has poor sensitivity and specificity. US shear wave elastography (SWE) is a newer technology that measures liver stiffness. This is a single-institution, prospective cohort study evaluating SWE in patients younger than 21 years who received HSCT from December 2015 through June 2017. SOS was defined using the modified Seattle criteria. Subjects had US with SWE at three scheduled time points...

The liver's capacity to grow in response to metabolic need is well known. However, long-term growth of liver allografts in pediatric recipients has not been characterized. A retrospective review of pediatric recipients at a single institution identified patients who had cross-sectional imaging at 1, 5, and 10 years post-transplant. Using volumetric calculations, liver allograft size was calculated and percent SLV were compared across the different time points; 18 patients ranging from 0.3 to 17.7 years old were identified that had imaging at 2 or more time points...

BACKGROUND: An atretic or hypoplastic portal vein (PV) represents a challenge for PV reconstruction in pediatric living donor liver transplantation (LDLT). Several PV venoplastic techniques have been developed. However, we still seek improved venoplastic techniques with better efficacy and compatibility. METHOD: From June 2016 to July 2017, 271 LDLT procedures were performed at the Department of Liver Surgery, Ren Ji Hospital. A total of 16 consecutive children with atretic and sclerotic PVs underwent a novel technique - the autogenous PV patch plastic technique...

The overall survival of children with solid tumors has shown a substantial increase in the past decades due to progress in all of the disciplines involved in the treatment. The poor prognosis for advanced stages of disease and the morbidity related to therapeutic procedures are still a challenge. Innovations in the surgical treatment of solid tumors can contribute to increase the survival rate of affected children and to decrease the treatment-related morbidity. Considering these aspects, the successful implementation of innovations is described based on four examples...

BACKGROUND: Early extubation immediately following liver transplantation is increasingly common in adult practice. Some pediatric institutions have begun to adopt this strategy. Careful patient selection is essential in minimizing risk. METHODS: This retrospective cohort study evaluated infants and children who underwent liver transplantation between July 2011 and December 2014. Our primary objective was to determine early extubation rate. Secondary objectives were to identify clinical factors associated with successful early extubation compared with delayed extubation and to examine significant postoperative complications, intensive care unit length of stay, and hospital length of stay...

Iron overload is a potential long-term complication among cancer survivors who received transfusions during treatment. Although there are screening guidelines for iron overload in pediatric survivors of hematopoietic stem cell transplant, these do not call for screening of other pediatric oncology patients. In our practice we incidentally discovered 3 patients in a population of 168 cancer survivors over the span of 17 years who were treated for cancer without hematopoietic stem cell transplant who had iron overload...

BACKGROUND AND AIM: Prognostic scoring systems (PSS) have not been validated in children with chronic Budd-Chiari syndrome (BCS). We aimed to analyse the long-term outcome of radiological intervention (RI) and validate the PSS in children. METHODS: Chronic BCS children were analysed in four subgroups: SI: successful intervention (primary or secondary stent patency) b) PO: poor outcome (refractory stent block or requirement of liver transplantation), c) NU: naïve unintervened (awaiting RI) and d) DBI: died before intervention...

The incidence of acute kidney injury (AKI) and its impact on chronic kidney disease (CKD) following pediatric non-kidney solid organ transplantation is unknown. We aimed to determine the incidence of AKI and CKD and examine their relationship among children who received a heart, lung, liver or multi-organ transplant at the Hospital for Sick Children between 2002 and 2011. AKI was assessed in the first year post-transplant. Among 303 children, perioperative AKI (within the first week) occurred in 67% of children, and AKI after the first week occurred in 36%, with the highest incidence among lung and multi-organ recipients...

BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Currently, liver transplantation (LT) for HCC is the only hope for cure from the tumor and from end-stage liver disease (ESLD). The organ pool shortage in deceased donor LT and the donor-related ethical concerns in living-donor LT necessitate the use of rigorous criteria for LT for HCC. In this respect, two main criteria for LT for HCC were implemented with good outcome, namely, the Milan and the University of California San Francisco criteria...

Diagnosis of de novo autoimmune hepatitis (AIH) after orthotopic liver transplantation (OLT) is challenging especially in the absence of hyper-γ-globulinemia. Circulating autoantibodies are not sensitive nor specific in de novo AIH but when positive increase the diagnostic probability. We report the discovery of novel liver microsomal (LM) autoantibodies against CYP-2C19 in a 9-year-old boy with "de novo" AIH developed 7 years after OLT. Graft dysfunction presented with hypertransaminasemia (up to 400 IU/L), while serum γ-globulins remained within the normal range for age...

A spectrum of vascular complications can be seen in pediatric liver transplant patients, including occlusion and hemodynamically significant narrowing of the vessels that provide inflow to or outflow from the graft. Intraoperative Doppler ultrasound (US) has the potential benefit of identifying vascular complications in pediatric liver transplant patients prior to abdominal closure. Importantly, intraoperative Doppler US can be used as a problem-solving tool in situations such as position-dependent kinking of the portal or hepatic veins, or in suspected vasospasm of the hepatic artery...

AIM: To investigate the rates of pretransplantation fetal-maternal microchimerism (MC) and its effect on rejection in children receiving maternal liver grafts. METHODS: DNA or blood samples before liver transplantation (LT) were available in 45 pediatric patients and their mothers. The presence of pretransplantation MC to non-inherited maternal antigens (NIMAs) (NIMA-MC) in the peripheral blood was tested using nested PCR-single-strand conformation polymorphism analysis for the human leukocyte antigen (HLA)-DRB1 alleles...

Undifferentiated embryonal sarcoma of the liver (UESL) is a malignancy of mesenchymal origin observed predominantly in the pediatric population and very rarely in adults. We describe the case of a 21-year-old male who presented with acute onset of right upper quadrant pain and distention. Physical examination of the patient revealed right upper quadrant tenderness with the lower border of the liver palpable, 4 cm below the right costal margin. Laboratory tests performed on admission showed that the patient's liver function tests, urinalysis, complete blood count, and basic metabolic panel were within reference range...
