INTRODUCTION: Portal vein embolization or ligation (PVE/PVL) is part of most multi-stage liver procedures in the case of low future liver remnant volume (FLRV). PVE initiates compensatory hypertrophy of non-occluded liver parenchyma. This hypertrophy is stimulated by an increased volume of portal blood in the non-occluded veins. PVE results in adequate FLRV growth necessary for resection only in 63-96% patients. The aim of this publication is to summarize the possibilities of influencing liver regeneration after PVE/PVL in an experiment using cytokines (TNF-α, IL-6), a monoclonal antibody against TGF-β1 (MAB TGF-β1) and mesenchymal stem cells (MSC)...

INTRODUCTION: Sinusoidal obstruction syndrome (SOS) is a disease which is caused by toxic injury to hepatic sinusoids. This syndrome is most frequently caused by myeloablative radiochemotherapy in patients before hematopoietic stem cells transplantation and also by oxaliplatin mainly in patients with colorectal liver metastases. The aim of this study was to establish a large animal model of SOS, which would enable further study of this disease and facilitate translation of experimental outcomes into human medicine...

Intrahepatic duct (IHD) stone is the presence of calculi within the intrahepatic bile duct specifically located proximal to the confluence of the left and right hepatic ducts. This stone is characterized by its intractable nature and frequent recurrence, requiring multiple therapeutic interventions. Without proper treatment, biliary strictures and retained stones can lead to repeated episodes of cholangitis, liver abscesses, secondary biliary cirrhosis, portal hypertension, and death from sepsis or hepatic failure...

BACKGROUND: X-linked hypophosphatemia is characterized by increased secretion of fibroblast growth factor 23 (FGF-23), which leads to hypophosphatemia and consequently rickets, osteomalacia, and skeletal deformities. We investigated burosumab, a monoclonal antibody that targets FGF-23, in patients with X-linked hypophosphatemia. METHODS: In an open-label, phase 2 trial, we randomly assigned 52 children with X-linked hypophosphatemia, in a 1:1 ratio, to receive subcutaneous burosumab either every 2 weeks or every 4 weeks; the dose was adjusted to achieve a serum phosphorus level at the low end of the normal range...

There have been many innovations in the field of ACL-reconstruction over the years, including the FlipCutter® and TightRope® system (both from Arthrex Inc.). The FlipCutter® is a combined guide pin and reamer that allows minimally invasive socket-creation from the inside out, especially in difficult-to-reach areas. The TightRope® is a further development of the well-known Endobutton™ (Smith & Nephew plc) that consists of a four-point knotless locking system. Its main advantage is its adjustability, which makes it possible to fill the entire bone socket with the graft without any empty space...

The tremendous advances in endoscopic skull base surgery added new a set of intricate less invasive approaches to the neurosurgical armamentarium. The new generations of neurosurgeons face the challenge of adopting the ever-changing technology and quickly learning modern surgical techniques beyond the traditional neurosurgery comfort zone. The future skull base surgeon must be well trained and knowledgeable in all surgical portals to the skull base in order to select the safest least invasive, most direct approach that offers the optimum exposure to handle a complex skull base pathology...

Hereditary pancreatitis (HP) is a progressive disease that can manifest in childhood with debilitating, relapsing pain. A total pancreatectomy and islet autotransplant (TPIAT) is a surgical option to relieve chronic pain while preserving the available beta-cell mass. The clinical course of HP is fraught with pancreatitis-related sequelae that can both necessitate and complicate a TPIAT. We describe a child with HP who developed a pancreatic pseudocyst-portal vein (PV) fistula. Active hemorrhage of the perforated PV into the pseudocyst and PV thrombosis complicated the planned TPIAT procedure and, preoperatively, required urgent image-guided stenting...

Histoplasma capsulatum is one of the most common pathogenic dimorphic fungi in Thailand. Its usual clinical syndrome is progressive disseminated histoplasmosis, whereas isolated hepatic histoplasmosis is extremely rare. Here, we report the world's first reported case of hepatic histoplasmosis with pylephlebitis in a 45-year-old Thai male who underwent orthotopic liver transplantation due to hepatitis B cirrhosis. Histopathology of the recipient's liver showed infiltration of fungal organisms in portal vein and hepatic granulomas...

Objective: Medical privacy policies, which are clear-cut for adults and young children, become ambiguous during adolescence. Yet medical organizations must establish unambiguous rules about patient and parental access to electronic patient portals. We conducted a national interview study to characterize the diversity in adolescent portal policies across a range of institutions and determine the factors influencing decisions about these policies. Methods: Within a sampling framework that ensured diversity of geography and medical organization type, we used purposive and snowball sampling to identify key informants...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) represents a spectrum of fat-related conditions ranging from simple fatty liver, to non-alcoholic steatohepatitis (NASH), fibrosis and cirrhosis. There is growing evidence that NAFLD is a multisystem disease, affecting several extra-hepatic organs and regulatory pathways. Furthermore, since the gut and liver are linked anatomically via the portal vein, disturbances of the gut microbiota (dysbiosis) can affect the liver. OBJECTIVES: In patients with NAFLD, we are testing the effects of a synbiotic which is the combination of a prebiotic (fructooligosaccharides; 4 g/day) and a probiotic (Bifidobacterium animalis subsp...

BACKGROUND: Islet grafts are transplanted into the liver via a portal vein in 90% of the clinical islet transplantations. However, the portal vein is far from being the ideal infusion site due to its unique drawbacks. These issues necessitated the exploration of an alternatively optimized site for clinical islet transplantation. With the widespread clinical application of percutaneous transhepatic puncture technique, we envisioned the possibility of islet transplantation into the hepatic sinus-tract (HST)...

Liver CT perfusion (CTP) is used in the detection, staging, and treatment response analysis of hepatic diseases. Unfortunately, CTP radiation exposures is significant, limiting more widespread use. Traditional CTP data processing reconstructs individual temporal samples, ignoring a large amount of shared anatomical information between temporal samples, suggesting opportunities for improved data processing. We adopt a prior-image-based reconstruction approach called Reconstruction of Difference (RoD) to enable low-exposure CTP acquisition...

Hepatitis B (HBV)-related fibrosis can be reversed after effective antiviral therapy. However, detailed changes of collagen characteristics during fibrosis regression remain unclear. Paired biopsy samples obtained from chronic hepatitis B patients were imaged with second harmonic generation/two photon excitation fluorescence (SHG/TPEF)-based microscopy to identify and quantify collagen features in portal, septal, and fibrillar areas. According to the changes of Ishak stage and qFibrosis score, a total of 117 patients with paired liver biopsy appeared to have four different outcomes after 78-week antiviral therapy: fast reverse (9%), reverse (63%), stable (15%), or progress (13%) on fibrosis...

BACKGROUND/OBJECTIVES: Acute pancreatitis (AP) progresses to necrotizing pancreatitis in 15% of cases. An important pathophysiological mechanism in AP is third spacing of fluids, which leads to intravascular volume depletion. This results in a reduced splanchnic circulation and reduced venous return. Non-visualisation of the portal and splenic vein on early computed tomography (CT) scan, which might be the result of smaller vein diameter due to decreased venous flow, is associated with infected necrosis and mortality in AP...
