Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF). Recurrence after resection of colorectal liver metastases (CRLMs), presumably caused by VEGF-mediated outgrowth of micrometastases, might decrease when VEGF is inhibited. This study examines the efficacy and safety of adding bevacizumab to an adjuvant regimen of CAPOX in patients undergoing radical resection for their CRLMs. Patients with resected CRLMs were randomized after surgery to receive CAPOX and bevacizumab (arm A) or CAPOX alone (arm B) as adjuvant treatment...

Adenosquamous carcinoma of the liver is a rare variant of cholangiocarcinoma. It is known to be a highly aggressive tumor with a poor prognosis, but its pathogenesis remains unclear owing to limited data in the literature. We report a case of 56-year-old woman who presented with a 1-week history of epigastric pain. Magnetic resonance imaging revealed a 6.5-cm ill-defined mass with low signal intensity in the left lobe of the liver, which was suspicious of cholangiocarcinoma. The patient underwent left hemihepatectomy...

A 15-year-old boy first presented with severe lung lesions and hypoxia and he was considered as a lung transplant candidate. Upon evaluation, hepatopulmonary syndrome, multiple nodular liver lesions, and Abernethy type 1b malformation were diagnosed. The patient underwent successful right lobe live donor liver transplantation, and all of the symptoms disappeared soon after the transplant. He is currently alive and well with excellent liver and lung functions 4 years after surgery.

Liver cancer is one of the leading causes of cancer-related mortality worldwide. Magnetic resonance imaging (MRI) is a non-invasive imaging technique that is often used by radiologists for diagnosis and surgical planning. Analysis of a large amount of liver MRI data for each patient limits the radiologist's efficiency and may lead to misdiagnoses. The redundant MRI data, especially from dynamic contrast enhanced (DCE) sequences, is also a bottleneck in transmitting the images via the internet or PACS for remote consultancy in a reasonable amount of time...

HCC represents the sixth most common cancer worldwide and the second leading cause of cancer-related death. Despite the high incidence, treatment options for advanced HCC remain limited and unsuccessful, resulting in a poor prognosis. Despite the major advances achieved in the diagnostic management of HCC, only one third of the newly diagnosed patients are presently eligible for curative treatments. Advances in technology and an increased understanding of HCC biology have led to the discovery of novel biomarkers...

Humanized mice are a powerful tool for the study of human hematopoiesis and immune function in vivo. However, the existing models cannot support robust adaptive immune responses, especially the generation of class-switched, antigen-specific antibody responses. Here we describe a new mouse strain, in which human IL6 gene encoding the cytokine that is important for B and T cell differentiation was knocked into its respective mouse locus. The provision of human IL6 not only enhanced thymopoiesis and periphery T-cell engraftment, but also significantly increased class switched memory B cells and serum IgG...

Background: Obesity is an epidemic and chronic disease that can bring other comorbidities to the patient. Non-alcoholic fatty liver disease is present in up to 90% of these patients and can progress to hepatitis and hepatocarcinoma. The relationship of this liver disease and obesity is already well known; however, it is possible that some parameters of the comorbidities are more related than others in the pathophysiology of the disease. Aim: Was analyzed the relationship between non-alcoholic fatty liver disease (NAFLD) and the comorbidities of metabolic syndrome in morbidly obese patients...

Background: Surgical strategy to increase the number of liver transplants in the pediatric population is the ex-situ liver transection (reduction or split). However, it is associated with complications such as hemorrhage and leaks. The human fibrinogen and thrombin sponge is useful for improving hemostasis in liver surgery. Aim: Compare pediatric liver transplants with ex-situ liver transection (reduction or split) with or without the human fibrinogen and thrombin sponge...

Many patients under oral anticoagulation therapy need percutaneous or surgical interventions/operations. For vitamin K antagonists (VKA), there are recommendations regarding preoperative or postoperative administration. Management of the new oral anticoagulants (NOAC) was supposed to be easier - but some aspects must be considered. Due to the different pharmacokinetic profiles of substances such as dabigatran, rivaroxaban, apixaban, and edoxaban, different recommendations are given.Upon periprocedural management, thromboembolic risk has to be considered in patients treated with NOACs...

We conducted a multicenter prospective study to clarify the efficacy and safety of surgery and imatinib for liver oligometastasis of gastrointestinal stromal tumors. Eligible gastrointestinal stromal tumor patients were enrolled in the surgery trial or the imatinib trial. Primary endpoints were recurrence-free survival and progression-free survival, respectively. The trials were prematurely terminated due to amendment of guidelines for adjuvant imatinib therapy and low patient accrual. In the surgery trial, all the six patients showed hepatic recurrence: median recurrence-free survival was 145 days (range: 62-1366 days)...

BACKGROUND: Only a limited number of centers have performed laparoscopic living donor hepatectomy to date. In particular, laparoscopic right hepatectomy is rarely performed because the procedure can only be performed by surgeons with significant experience in both laparoscopic liver surgery and liver transplantation with living donor liver grafts. METHODS: Between November 2014 and February 2015, in a pure laparoscopic approach program for living right lobe donors at Asan Medical Center, 92 living donors underwent right hepatectomy for adult living donor liver transplantation (LDLT)...

RATIONALE: Ectopic variceal bleeding is a rare (2-5%) but fatal gastrointestinal bleed in patients with portal hypertension. Patients with ectopic variceal bleeding manifest melena, hematochezia, or hematemesis, which require urgent managements. Definitive therapeutic modalities of ectopic varices are not yet standardized because of low incidence. Various therapeutic modalities have been applied on the basis of the experiences of experts or availability of facilities, with varying results...

Prosthetic grafts and patches are commonly used in cardiovascular surgery, however neointimal hyperplasia remains a significant concern, especially under low flow conditions. We hypothesized that delivery of rapamycin from nanoparticles (NP) covalently attached to patches allows sustained site-specific delivery of therapeutic agents targeted to inhibit localized neointimal hyperplasia. NP were covalently linked to pericardial patches using EDC/NHS chemistry and could deliver at least 360 ng rapamycin per patch without detectable rapamycin in serum; nanoparticles were detectable in the liver, kidney and spleen but no other sites within 24 hours...

A 61-year-old man presented with accumulation of ascites secondary to alcoholic liver disease. He had an ascitic drain sited and 24 hours later he developed acute colonic pseudo-obstruction (ACPO). This is a rare condition previously associated with major surgery and severe sepsis. The patient did well with conservative management, and avoided the need for endoscopic decompression or surgical intervention. We believe that this is the first report of ACPO secondary to abdominal paracentesis.
