Opinions of Dutch liver transplant recipients on anonymity of organ donation and direct contact with the donors family.

Background: In the Netherlands, anonymity of organ donation, which is currently protected by legislation, has come under discussion. In the Dutch society, a tendency to allow direct contact between transplant recipients and their donor's family is noticeable. As little is known about the opinion of Dutch liver transplant recipients on anonymity of organ donation and direct contact with the donor's family, this study examines their opinions.

Early elevated serum gamma glutamyl transpeptidase after liver transplantation is associated with better survival.

Background: Gamma glutamyl transpeptidase (GGT) is a membrane bound enzyme that plays a key role in the synthesis of the antioxidant glutathione. Epidemiological studies have linked high GGT with an increased risk of morbidity and cardiovascular mortality. In contrast, GGT is usually elevated in liver transplant recipients that experience good outcomes.

[The armed forces health service and its nurses in the Great War].

The First World War was characterised by the multitude of battlefields as well as by the alternating cycles of offensive phases followed by periods of trench warfare. The reality of the fighting, far removed from initial expectations, had major repercussions on the organisation of healthcare services. Nurses played a central role in the healthcare provided during this conflict.

Management of coagulation abnormalities in liver disease.

Liver disease is characterized by changes in all phases of hemostasis. These hemostatic alterations were long considered to predispose patients with liver disease towards a bleeding tendency, as they are associated with prolonged conventional coagulation tests. However, these patients may also suffer from thrombotic complications, and we now know that the hemostatic system in patient with liver disease is, in fact, in a rebalanced state.

Shared decision making in transplantation: how patients see their role in the decision process of accepting a donor liver.

At the time of the organ offer for transplantation, donor-related risks such as disease transmission and graft failure are weighed against the patient's risk of remaining on the waiting list. The patient's commonly inactive role in decision making and the timing and extent of donor-specific risk information have been discussed in the medical literature. This is the first study revealing the opinions of liver patients on these issues.

The quest for Luschka's duct: an eponym leading a life of its own?

Background: The German anatomist Hubert von Luschka gave name to several structures in the human body. One of great discussion is the duct of Luschka, part of the biliary system. There are different descriptions of the duct of Luschka.

Subnormothermic machine perfusion for ex vivo preservation and recovery of the human liver for transplantation.

To reduce widespread shortages, attempts are made to use more marginal livers for transplantation. Many of these grafts are discarded for fear of inferior survival rates or biliary complications. Recent advances in organ preservation have shown that ex vivo subnormothermic machine perfusion has the potential to improve preservation and recover marginal livers pretransplantation.

Biliary complications after orthotopic liver transplantation.

Purpose Of Review: The incidence, pathogenesis and management of the most common biliary complications are summarized, with an emphasis on nonanastomotic biliary strictures (NAS) and potential strategies to prevent NAS after liver transplantation.

Recent Findings: NAS have variable presentations in time and localization, suggesting various underlying pathogeneses. Early-onset NAS (presentation within 1 year) have shown to be largely related to ischemia-induced bile duct injury, whereas late-onset NAS [>1 year after orthotopic liver transplantation (OLT)] have more immune-mediated causes.

Hemostasis in liver disease: implications of new concepts for perioperative management.

The hemostatic profile of patients with liver diseases is frequently profoundly different from that of healthy individuals. These complex alterations lead to abnormal results from routine laboratory tests, but because of the nature of these assays, they fail to accurately represent the patient's hemostatic state. Nevertheless, based on abnormal laboratory coagulation values, it has long been assumed that patients with liver disease have a natural bleeding tendency and are protected from thrombosis.

Staging laparoscopy in patients scheduled for pancreaticoduodenectomy minimizes hospitalization in the remaining life time when metastatic carcinoma is found.

Objective: To compare the burden of total hospitalization as a ratio of survival of staging laparoscopy versus prophylactic bypass surgery in patients with unresectable periampullary adenocarcinoma.

Background: Periampullary adenocarcinoma is an aggressive cancer with up to 35% of the patients at surgery found to be unresectable. Palliative prophylactic surgical bypass versus endoscopic stenting has been addressed by randomized controlled trials, but none reported on the burden of hospitalization.

Activation of Type 3 innate lymphoid cells and interleukin 22 secretion in the lungs during Streptococcus pneumoniae infection.

Mucosal sites are continuously exposed to pathogenic microorganisms and are therefore equipped to control respiratory infections. Type 3 innate lymphoid cells (ILC3) are key players in antimicrobial defense in intestinal mucosa, through interleukin 17 and interleukin 22 (IL-22) production. The present study aimed at analyzing the distribution and function of ILC3 in the respiratory tract.

Injury to peribiliary glands and vascular plexus before liver transplantation predicts formation of non-anastomotic biliary strictures.

Background & Aims: The peribiliary glands of large bile ducts have been identified as a niche of progenitor cells that contribute to regeneration of biliary epithelium after injury. We aimed to determine whether injury to the peribiliary glands of donor livers is a risk factor for development of non-anastomotic biliary strictures (NAS) after liver transplantation.

Methods: In 128 liver transplant procedures, biopsies were taken from the donor bile duct and injury was assessed using an established histological grading system.

Hypothermic oxygenated machine perfusion prevents arteriolonecrosis of the peribiliary plexus in pig livers donated after circulatory death.

Background: Livers derived from donation after circulatory death (DCD) are increasingly accepted for transplantation. However, DCD livers suffer additional donor warm ischemia, leading to biliary injury and more biliary complications after transplantation. It is unknown whether oxygenated machine perfusion results in better preservation of biliary epithelium and the peribiliary vasculature.

Differential in vitro inhibition of thrombin generation by anticoagulant drugs in plasma from patients with cirrhosis.

Background: Treatment and prevention of thrombotic complications is frequently required in patients with cirrhosis. However anticoagulant therapy is often withheld from these patients, because of the perceived bleeding diathesis. As a result of the limited clinical experience, the anticoagulant of choice for the various indications is still not known.

Duct-to-duct reconstruction in liver transplantation for primary sclerosing cholangitis is associated with fewer biliary complications in comparison with hepaticojejunostomy.

There is no consensus on the preferred type of biliary reconstruction for patients undergoing orthotopic liver transplantation (OLT) for primary sclerosing cholangitis (PSC). The aim of this study was to compare long-term outcomes after OLT for PSC using either duct-to-duct anastomosis or Roux-en-Y hepaticojejunostomy for biliary reconstruction. In a consecutive series of 98 adult patients undergoing OLT for PSC, 45 underwent duct-to-duct reconstruction, and 53 underwent Roux-en-Y biliary reconstruction.

Routine coagulation assays underestimate levels of antithrombin-dependent drugs but not of direct anticoagulant drugs in plasma from patients with cirrhosis.

There is increasing recognition that thrombotic complications may occur in patients with cirrhosis, and literature on antithrombotic treatment in these patients is rapidly emerging. Due to extensive haemostatic changes in patients with cirrhosis, careful monitoring of anticoagulant therapy may be required. Recent data suggest that plasma levels of low molecular weight heparin (LMWH) are substantially underestimated by the anti-activated factor X (anti-Xa) assay in patients with cirrhosis.

Influence of preoperative chemotherapy on CT volumetric liver regeneration following right hemihepatectomy.

Background: An increasing number of patients undergo major liver resection following preoperative chemotherapy. Liver regeneration may be impaired in these patients, predisposing them to postoperative liver dysfunction. The aim of the present study was to evaluate the effects of preoperative chemotherapy on liver regeneration after partial liver resection.

In vitro effects of proteases in human pancreatic juice on stability of liquid and carrier-bound fibrin sealants.

Background: Fibrin sealants are used in pancreatic surgery to prevent leakage of pancreatic fluid and reduce associated complications. The efficacy of this approach is unclear.

Methods: Fibrin clots were generated in vitro from two commercially available liquid fibrin sealants (Tissucol Duo® and Evicel®) and the carrier-bound fibrin sealant Tachosil®, and exposed to normal saline or human pancreatic fluid.

Recipient's genetic R702W NOD2 variant is associated with an increased risk of bacterial infections after orthotopic liver transplantation.

Introduction: Orthotopic liver transplantation (OLT) is accompanied by a significant postoperative infection risk. Immunosuppression to prevent rejection increases the susceptibility to infections, mainly by impairing the adaptive immune system. Genetic polymorphisms in the lectin complement pathway of the donor have recently been identified as important risk determinants of clinically significant bacterial infection (CSI) after OLT.
