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...

NEC is an idiopathic intestinal mucosal injury that may progress to transmural bowel necrosis without mesenteric ischemia. NEC usually affects 7- to 10-day-old neonates following enteral feeding. A 10-month-old girl with no history of laparotomy underwent LDLT for acute liver failure. After starting enteral feeding on postoperative day 5, she developed abdominal distention. Diffuse PVG and PI were detected by radiologic modalities. Exploratory laparotomy revealed patchy necrosis of the intestine without perforation...

Neonatal liver disease is an important source of morbidity in the pediatric population. The manifestation of liver disease in young infants may be different than in older patients, and there are a number of diagnoses that are unique to this age group. Familiarity with these entities is important as imaging plays a key role in the diagnostic workup, and prompt diagnosis is necessary to prevent complications. This article reviews the spectrum of liver pathologies that can manifest in the first 6 months of life and is intended to educate the general radiologist who may be faced with interpretation of neonatal liver imaging...

Cytomegalovirus (CMV) duodenitis is a rare occurrence, especially in pediatric patients. A thirteen-month-old female presented to the Emergency Department for a febrile seizure. She was incidentally admitted for severe malnutrition with an initial workup remarkable for only a slight elevation in her ALT at 48. The patient was found to have an oral aversion requiring nasogastric tube feeds for adequate caloric intake. She continued to fail to gain weight and underwent an EGD that demonstrated a duodenal ulcer...

PURPOSE: Pediatric patients with intestinal failure need long-term parenteral nutrition (PN), but this nutritional support causes liver dysfunction, such as intestinal failure-associated liver disease (IFALD). Several studies have shown that the lipid emulsion produced by soybean oil (SO) is associated with the occurrence of IFALD. In this study, we evaluated the effect of SO and fish oil (FO) lipid emulsion on hepatic steatosis. METHODS: Sprague-Dawley rats underwent jugular vein catheterization and were divided into three groups: sham operation with normal chow (Sham group), 80% small bowel resection (80% SBR) + TPN with SO lipid emulsion (SO group), and 80% SBR + TPN with FO lipid emulsion (FO group)...

BACKGROUND: Technetium-99m-hydrazinonicotinamide-Tyr(3)-octreotide ((99m)Tc-HYNIC-TOC) is recognized as a promising radiopharmaceutical for diagnosing neuroendocrine tumors (NETs). However, (99m)Tc-HYNIC-TOC dosimetry has been investigated only for adults. As pediatric radionuclide therapies become increasingly common, similar dosimetric studies for children are urgently needed. The aim of this study is to report personalized image-based biodistributions and dosimetry evaluations for children studies performed using (99m)Tc-HYNIC-TOC and to compare them with those from adult subjects...

BACKGROUND: Orthotopic liver transplantation (OLT) is considered the standard for children with hepatoblastoma (HB) in whom complete surgical resection is not possible. However, OLT is not always available or feasible. OBJECTIVE: To describe the outcome of children with HB who were initially deemed unresectable and underwent complex hepatectomy with planned close margins, and ultimately avoided OLT. METHODS: Demographic data, surgical and pathologic details, and survival information were collected from children treated for HB between January 2010 to December 2015...

BACKGROUND AND OBJECTIVES: Biliary atresia (BA) is a pediatric liver disease characterized by fibro-obliteration and obstruction of the extrahepatic biliary system, that invariably leads to cirrhosis and even death, if left untreated for extended time. However, its pathology and etiology still remained unknown. In this study, we tested the expression of adducin 3 (ADD3), the gene identified as a susceptibility gene in BA by GWAS, and uncovered its upstream regulatory microRNA in the pathogenesis of BA...

OBJECTIVE: Endoscopic retrograde cholangiopancreatography (ERCP) is used to manage biliary pathology in pediatric patients. Plastic biliary stents have been utilized in this population for obstructive lesions and bile leaks, however they are sometimes not effective due to migration, occlusion, or ineffective sealing. Fully covered self-expanding metal stents (FCSEMS) have larger diameters making them more suitable for some situations. However, their use in pediatrics has not been defined...

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by excessive activation of the immune system, resulting in overproduction of inflammatory cytokines. Patients usually present with high fever, cytopenias, hyperferritinemia, and hepatosplenomegaly, and their disease process ranges from mild to fatal multiorgan failure. HLH is a heterogeneous group of disorders that can be triggered by infections, neoplasms, or autoimmune diseases. The HLH diagnosis can be difficult to confidently confirm in critically ill patients while waiting for pathology or reference laboratory results to return, delaying the diagnosis with significantly worsened outcomes...

BACKGROUND: Minimally invasive surgery has been validated to be a new standard in living donor hepatectomy for adult-to-pediatric transplantation with less morbidity [1]. Laparoscopic donor hepatectomy can reduce the major concerns about pain and morbidity associated with open surgery and a slow return to daily activities of donors [2]. Herein, we present one case of totally laparoscopic living donor left hepatectomy including the middle hepatic vein (MHV). DONOR AND METHOD: A 37-year-old mother volunteered to donate to her 3-year-old son with biliary atresia (PELD score 7)...

Extragonadal teratoma originating from the retroperitoneum represents less than 5% of all teratomas and accounts for less than 10% of all pediatric retroperitoneal neoplasms. To date, there has been no report of teratoma managed with LT. This study reports an infant aged 3 months with retroperitoneal immature teratoma involving the hepatic hilum, refractory to chemotherapy and treated with LT. The patient was referred to our hospital for management of a growing abdominal mass. Histopathology of a fine needle biopsy of the lesion suggested the possibility of a hepatoblastoma with teratoid features...

Background: Liver resection (LR) is the treatment of choice for most benign and malignant focal liver lesions, as well as in selected patients with liver trauma. Few other therapies can compete with LR in selected cases, such as liver transplantation in hepatocellular carcinoma (HCC) and ablative therapies in small HCCs or liver metastases. The present paper analyses a single center experience in LR, reviewing the indications of LR, the operative techniques and their short-term results. MATERIAL AND METHOD: Between January 2000 and December 2016, in "œDan Setlacec" Center of General Surgery and Liver Transplantation were performed 3165 LRs in 3016 patients, for pathologic conditions of the liver...
