RESUMO

INTRODUCTION: Kidney transplantation (KTx) necessarily conveys an ischemia/reperfusion (I/R) process, which impacts on allograft outcomes. Delayed graft function (DGF) is defined as a non-decrease of serum creatinine by at least 10% daily on 3 consecutive days during the first 7 days post-KTx. DGF significantly conditions both short- and long-term graft outcomes. Still there is a lack of DGF predictive biomarkers. OBJECTIVES: This study aimed to explore the potential of kidney graft perfusate metabolomics to predict DGF occurrence. METHODS: 49 human perfusates from grafts categorized upon donor type [donation after brain death (DBD)/donation after circulatory death (DCD)] and DGF occurrence and 19 perfusates from a murine model classified upon death type (DBD/DCD) were collected and analyzed by NMR-based metabolomics. RESULTS: The multivariate analysis of the murine data highlighted significant differences between perfusate metabolomes of DBD versus DCD. These differences were similarly observed in the human perfusates. After correcting for the type of donor, multivariate analysis of human data demonstrated a metabolomics signature that could be correlated with DGF occurrence. CONCLUSIONS: The metabolome of kidney grafts is influenced by the donor's type in both human and pre-clinical studies and could be correlated with DGF in the human DBD cohort. Thus, metabolomic analysis of perfusate applied prior to KTx may represent a new predictive tool for clinicians in a more personalized management of DGF. Moreover, our data paves the way to better understand the impact of donor's types on the biochemical events occurring between death and the hypothermic storage.

RESUMO

Renal allograft rejection involves many mechanisms of innate and adaptive immunity, responsible for parenchymal inflammatory lesions that negatively impact the long-term outcomes of the renal allograft. The heterogeneous presentations of rejections in terms of clinical, biological and histological aspects make them difficult to manage in daily clinical practice. Indeed, current therapeutic strategies are disappointing in term of long-term outcomes, including graft survival. In this article, we will discuss the main effector mechanisms of rejection and their histological classification, as well as the existing treatments and those currently under evaluation.


: Le rejet du greffon rénal fait intervenir de nombreux mécanismes de l'immunité innée et adaptative, responsables de lésions inflammatoires parenchymateuses impactant négativement le devenir au long cours du greffon rénal. La grande hétérogénéité dans la présentation clinique, biologique et histologique des rejets de greffe en fait des entités difficiles à prendre en charge en pratique clinique quotidienne. En effet, les stratégies thérapeutiques actuelles montrent des résultats assez décevants pour le traitement des rejets, ce qui a comme conséquence une diminution significative de la survie des greffons. Nous aborderons dans cet article les principaux mécanismes effecteurs des rejets, leur classification histologique ainsi que les traitements existants et en cours de validation.

RESUMO

Cellular immunotherapy consists in using the cells of the immune system as a therapeutic weapon. In this constantly evolving field, the therapeutic strategies developed at the University Hospital of Liege are hematopoietic stem cell transplantation, mesenchymal stromal cells and targeted therapy with CAR-T cells (Chimeric Antigen Receptor T cells). The first two modalities represent a form of non-targeted cell therapy that has been developed over the past decades. While hematopoietic stem cell transplantation is established as the reference treatment for many hematological diseases, mesenchymal stromal cells are still under investigation in various pathologies (notably Crohn's disease, organ transplantation, COVID-19 and pulmonary fibrosis). By contrast, CAR-T cells represent a recently developed and extremely promising targeted immunotherapy. This therapeutic approach has already revolutionized the treatment of B-cell lymphopathies, and has the potential to do the same for many other diseases in the near future.


L'immunothérapie cellulaire consiste en l'utilisation de cellules du système immunitaire comme arme thérapeutique. Dans ce domaine en évolution constante, les stratégies thérapeutiques développées au CHU de Liège sont la greffe de cellules souches hématopoïétiques, les cellules stromales mésenchymateuses et la thérapie ciblée par cellules CAR-T («Chimeric Antigen Receptor T cells¼). Les deux premières approches représentent une forme de thérapie cellulaire non ciblée, développées depuis de nombreuses années. Si la greffe de cellules souches hématopoïétiques est établie comme le traitement de référence de nombreuses hémopathies, les cellules stromales mésenchymateuses sont, quant à elles, toujours à l'étude dans diverses pathologies (notamment maladie de Crohn, transplantation d'organes, COVID-19 et fibrose pulmonaire). À l'opposé, les cellules CAR-T représentent une immunothérapie ciblée, développée récemment et extrêmement prometteuse. Cette modalité thérapeutique a déjà révolutionné le traitement des lymphopathies B, et elle possède le potentiel d'en faire de même pour de nombreuses autres pathologies dans un avenir proche.

RESUMO

BACKGROUND: The extent of liver resection for tumours is limited by the expected functional reserve of the future liver remnant (FRL), so hypertrophy may be induced by portal vein embolization (PVE), taking 6 weeks or longer for growth. This study assessed the hypothesis that simultaneous embolization of portal and hepatic veins (PVE/HVE) accelerates hypertrophy and improves resectability. METHODS: All centres of the international DRAGON trials study collaborative were asked to provide data on patients who had PVE/HVE or PVE on 2016-2019 (more than 5 PVE/HVE procedures was a requirement). Liver volumetry was performed using OsiriX MD software. Multivariable analysis was performed for the endpoints of resectability rate, FLR hypertrophy and major complications using receiver operating characteristic (ROC) statistics, regression, and Kaplan-Meier analysis. RESULTS: In total, 39 patients had undergone PVE/HVE and 160 had PVE alone. The PVE/HVE group had better hypertrophy than the PVE group (59 versus 48 per cent respectively; P = 0.020) and resectability (90 versus 68 per cent; P = 0.007). Major complications (26 versus 34 per cent; P = 0.550) and 90-day mortality (3 versus 16 per cent respectively, P = 0.065) were comparable. Multivariable analysis confirmed that these effects were independent of confounders. CONCLUSION: PVE/HVE achieved better FLR hypertrophy and resectability than PVE in this collaborative experience.

RESUMO

Cystic hepatic lesions are frequent and sometimes large. They are generally asymptomatic and discovered by chance. The differential diagnosis of these lesions includes congenital, post-traumatic, benign or malignant tumors, as well as infectious pathologies. Conventional or contrast ultrasonography, abdominal computed tomography and magnetic resonance imaging can be used to characterize them. Therapeutic abstention with or without iconographic monitoring constitutes the optimal management of many benign liver cysts without clinical repercussions. Treatments for symptomatic or potentially aggressive lesions may include fenestration, puncture with sclerotherapy, or surgical resection. In this article, the authors discuss how to diagnose and treat the various hepatic cystic lesions.


Les lésions kystiques hépatiques sont fréquentes et parfois volumineuses. Elles sont généralement asymptomatiques et de découverte fortuite. Le diagnostic différentiel de ces lésions inclut des pathologies congénitales, post-traumatiques, tumorales bénignes ou malignes ainsi qu'infectieuses. L'échographie conventionnelle ou avec contraste, le scanner abdominal et la résonance magnétique nucléaire peuvent être utilisés pour les caractériser. L'abstention thérapeutique, avec ou sans surveillance iconographique, constitue la prise en charge optimale de nombreux kystes bénins sans répercussion clinique. Les traitements des lésions symptomatiques ou potentiellement agressives peuvent inclure la fenestration, la ponction avec sclérothérapie ou la résection chirurgicale. Dans cet article, les auteurs discutent des modalités de diagnostic et de traitement des diverses lésions kystiques hépatiques.

RESUMO

The authors report the case of a 41-year-old patient originating from Algeria who developed obstructive cholangitis caused by the membrane of a ruptured hydatid cyst leading to the diagnosis of cystic echinococcosis. Cystic echinococcosis can be asymptomatic for several years until a complication occurs, such as in this case an obstruction of the common bile duct, or cholangio-hydatidosis. This cause of jaundice is uncommon in Western Europe whereas it is more frequent in endemic areas. Identification and treatment of ruptured cysts are mandatory because of the mortality rate of these complications if left untreated. In this particular case, the treatment by endoscopic retrograde cholangiopancreatography was successful.


Les auteurs rapportent le cas d'un patient de 41 ans, originaire d'Algérie, chez qui un diagnostic d'échinococcose a été posé à la suite d'une cholangite obstructive sur rupture d'un kyste hydatique. L'échinococcose kystique peut être asymptomatique pendant plusieurs années jusqu'à ce qu'une complication ne survienne, comme une obstruction du canal cholédoque commun appelée également cholangio-hydatidose. Cette cause d'ictère est rare en Europe occidentale alors qu'elle est plus fréquente dans les zones endémiques. L'identification et le traitement des kystes rompus sont nécessaires en raison du taux de mortalité de ces complications lorsqu'elles ne sont pas traitées de manière adéquate. Dans ce cas particulier, le traitement par cholangio-pancréatographie rétrograde endoscopique s'est révélé efficace.

RESUMO

Hepato-pulmonary syndrome (HPS) is a pulmonary vascular complication of cirrhosis quite frequent but often under-diagnosed, and characterized by intra-pulmonary capillary and pre-capillary vascular dilatations that may lead to severe hypoxemia. HPS is often asymptomatic but may induce a progressive dyspnea. HPS diagnosis is based on arterial gasometry that proves the hypoxemia and contrast-enhanced echo-cardiography revealing the vascular dilatations. Screening of HPS is recommended in every cirrhotic patient complaining of dyspnea or in every liver transplantation candidate. Indeed, the only effective treatment of HPS is liver transplantation; HPS patients receive exception-points in the MELD (Model for End-Stage Liver Disease) liver allocation score. The authors report herein the case of a 39-year-old male patient with a cirrhosis of unknown origin complicated by HPS which appeared as a disabling dyspnea. This patient underwent liver transplantation a year after HPS diagnosis and recovered completely.


Le syndrome hépatopulmonaire est une complication vasculaire pulmonaire de la cirrhose relativement fréquente et sous-diagnostiquée, caractérisée par des vasodilatations capillaires et pré-capillaires intrapulmonaires pouvant entraîner une hypoxémie sévère. Souvent asymptomatique, ce syndrome se révèle le plus souvent par une dyspnée d'apparition progressive. Le diagnostic est réalisé par une gazométrie artérielle prouvant l'hypoxémie et une échographie cardiaque de contraste démontrant l'existence de vasodilatations intrapulmonaires. Le dépistage du syndrome hépatopulmonaire est préconisé chez tout patient atteint de cirrhose présentant de la dyspnée et chez tout patient candidat à une greffe hépatique. En effet, le seul traitement efficace est la transplantation hépatique, et ces patients bénéficient d'ailleurs de points d'exception dans le calcul du score de MELD («Model for End-Stage Liver Disease¼). Nous rapportons ici le cas d'un patient de 39 ans atteint d'une cirrhose d'origine indéterminée compliquée d'un syndrome hépatopulmonaire qui s'est révélé par une dyspnée devenue rapidement invalidante. Ce patient a pu bénéficier d'une transplantation hépatique un an après le diagnostic de syndrome hépatopulmonaire, permettant ainsi une guérison complète tant sur plan hépatique que pulmonaire.

RESUMO

The «Severe Acute Respiratory Syndrome coronavirus 2¼ (SARS-CoV-2) pandemic has disrupted medical care and intra-hospital organization during 2020, both in Belgium and throughout the world. Solid organ transplantation was not spared and in Belgium, the number of organ donors and transplants overall decreased by 20 % for livers and by 33 % for hearts between 2019 and 2020. The aim of this article is to summarize the experience acquired in 2020 and 2021 on the organizational and medical implications of the coronavirus disease 2019 (COVID-19) pandemic with regard to the care of patients transplanted or awaiting for organ transplants, and to draw conclusions both for the aftermath of COVID-19 but also for future pandemics. Vaccination against SARS-CoV-2 is highly recommended and particularly important in organ transplant recipients, even if the response rate is lower than in the non-transplanted population. A third injection is now advised in immunosuppressed patients.


La pandémie de «Severe Acute Respiratory Syndrome coronavirus 2¼ (SARS-CoV-2) a bouleversé les soins médicaux et l'organisation intra-hospitalière durant l'année 2020 en Belgique et dans le monde. La transplantation d'organes ne fut pas épargnée. En Belgique, le nombre de donneurs d'organes et de transplantations a globalement diminué de 20 % pour les foies et de 33 % pour les cœurs entre 2019 et 2020. Le but de cet article est de résumer l'expérience acquise en 2020 et 2021 sur les implications organisationnelles et médicales de la pandémie de «coronavirus disease 2019¼ (COVID-19) quant à la prise en charge des patients transplantés ou en attente de greffe d'organes, et d'en tirer les conclusions à la fois pour les suites de la COVID-19, mais aussi pour les éventuelles futures pandémies. La vaccination anti-SARS-CoV-2 est recommandée et particulièrement importante chez les patients transplantés d'organe, même si le taux de réponse est inférieur à la population non transplantée. Une troisième injection est conseillée chez les patients immunodéprimés.

RESUMO

In Belgium and around the world, the incidence of primary malignant liver tumours is increasing, both for hepatocarcinoma and cholangiocarcinoma. Their curative treatment is based on multidisciplinary and specialized care, of which surgery (including liver transplantation) remains the cornerstone, often associated with other logoregional treatments, as radioembolisation, radiofrequency ablation, and chemoembolisation. For advanced cases, the prognosis remains poor, in particular due to a certain chemoresistance of these tumours. New treatments include targeted therapies (including various tyrosine kinase inhibitors) and immunotherapy. A specialized multidisciplinary discussion is therefore necessary to define the best therapeutic management, individualized to each patient. In this article, the authors review the most recent data relating to the treatment of hepatocarcinoma and cholangiocarcinoma.


En Belgique et dans le monde, l'incidence des tumeurs malignes primitives du foie augmente, tant pour l'hépatocarcinome que le cholangiocarcinome. Leur traitement curatif repose sur une prise en charge multidisciplinaire et spécialisée, dont la chirurgie (incluant la transplantation hépatique) reste la pièce angulaire, souvent associée à d'autres traitements logo-régionaux (radioembolisation, radiofréquence, chimio-embolisation). Pour les cas avancés, le pronostic reste sombre, notamment en raison d'une certaine chimiorésistance de ces tumeurs. Les nouvelles prises en charge incluent des thérapies ciblées (notamment, divers inhibiteurs de tyrosine kinase) et de l'immunothérapie. Une discussion pluridisciplinaire spécialisée est donc nécessaire pour définir la meilleure prise en charge thérapeutique, individualisée pour chaque patient. Dans cet article, les auteurs revoient les données récentes relatives au traitement de l'hépatocarcinome et du cholangiocarcinome.

RESUMO

The success of solid organ transplantation induced an increased need for grafts and the necessary registration of transplant candidates on long waiting lists. Many patients die while waiting for transplantation, even in Belgium where the donation rates have been high these last years. In order to fight this lack of donor organs, the transplant centers widened donation criteria for brain dead donors, including older age and potential transmissible diseases. In addition, programs of donation after circulation death have been developed, first for kidneys, then for livers and recently for the hearts. Organ donation after euthanasia is also regularly performed in Belgium. All these policies lead to the fact that organ donation rates stay high in Belgium, and particularly in the Liege region, but efforts are still ahead if we aim to reduce waiting list mortalities.


Le succès des transplantations a entraîné un besoin important en organes et la nécessité d'inscrire les patients candidats à la greffe sur de longues listes d'attente. De trop nombreux patients meurent avant d'avoir pu bénéficier de la transplantation, malgré le fait que la Belgique soit un des pays du monde où le taux de prélèvement est, proportionnellement, le plus élevé. Afin de lutter contre ce manque d'organes, les centres de transplantation ont élargi les critères de prélèvement des donneurs en mort cérébrale, tant au niveau de leur âge qu'au niveau de certaines maladies potentiellement transmissibles. De plus, des programmes de prélèvement à partir de donneurs en mort circulatoire ont également été développés avec succès, d'abord pour les reins et le foie, plus récemment pour le coeur. Les prélèvements d'organes sont également réalisables après euthanasie. L'ensemble de ces politiques fait que le taux de prélèvement d'organes après décès reste élevé en Belgique, et particulièrement dans la région liégeoise, mais des efforts doivent encore être réalisés si l'on veut encore réduire la mortalité en liste d'attente.

RESUMO

During the last decade minimal invasive approach progressed in all sectors of abdominal surgery. Technological improvements allowed to perform more complex procedures laparoscopically with increased safety. The implementation of pre-, per- and postoperative protocols with an adaptation of surgical, anesthetic and analgesia methods and the patient's involvement in the healing process led to enhanced recovery after surgery. The centralization of complex esophageal and pancreatic surgery established the CHU of Liège as a tertiary referral institution for complex oncological surgery thanks to a large cooperation with regional hospitals.


La dernière décennie a vu progresser l'approche mini-invasive dans tous les domaines de la chirurgie abdominale. Les améliorations technologiques permettent de réaliser des interventions toujours plus complexes en laparoscopie avec une sécurité accrue. La systématisation de la prise en charge pré-, per- et postopératoire, avec une adaptation des techniques de chirurgie, d'anesthésie et d'analgésie, et une implication du patient dans ce processus ont abouti à une réhabilitation accélérée. La centralisation de la chirurgie complexe de l'oesophage et du pancréas a permis de créer une structure de référence en chirurgie oncologique complexe au CHU de Liège grâce à une large collaboration interhospitalière régionale.

RESUMO

In Belgium as in many other countries, alcohol is one of the leading causes of adult liver transplantation. Liver transplantation for terminal liver failure due to excessive alcohol intake raises clear ethical issues concerning the use of grafts to save patients suffering from a self-inflecting affection. Alcoholic liver disease is one of the best indications for liver transplantation, with excellent results in terms of length of survival and post transplantation quality of life, if this transplantation is proposed by a multidisciplinary team in a patient able to and helped by a supporting family and social environment.


En Belgique, comme dans beaucoup d'autres pays, la maladie alcoolique constitue une des causes les plus fréquentes menant à la transplantation hépatique chez l'adulte. Or la transplantation hépatique chez des patients alcooliques pose de claires questions éthiques concernant l'utilisation de greffons pour soigner des patients souffrant d'une maladie trop souvent considérée comme étant auto-infligée. La maladie alcoolique du foie est une des meilleures indications de greffe hépatique, avec d'excellents résultats en termes de durée de survie et de qualité de vie après transplantation. Le pré-requis est que cette transplantation soit proposée par une équipe multidisciplinaire, chez un patient capable de se prendre en charge et soutenu par un environnement familial et social favorable.

RESUMO

Alcoholic hepatitis is a syndrome defined primarily by the clinical onset of jaundice in patients with a concomitant heavy consumption of alcoholic beverages. This pathology is managed by alcohol withdrawal with a 30-day survival rate of 90 %. For patients with severe alcoholic hepatitis, with a Maddrey score greater than 32 (taking into account bilirubin and prothrombin time), treatment with corticosteroids is discussed provided that a possible infection can be sufficiently excluded or adequately managed. The administration of corticosteroids is continued for 28 days if the Lille score, calculated after 7 days of treatment, is favourable (inferior to 0.45), leading to a survival rate of 80-90 %. However, if the Lille score is unfavourable (superior to 0.45), the prognosis is bad, with a survival of only 25-30 % at 6 months. Special attention needs to be paid to assure a sufficient caloric intake during the treatment period for a successful management. Liver transplantation, previously prohibited for this indication, can be discussed under certain circumstances. However, the success of treatment is contingent upon the alcohol withdrawal. Innovative drugs are currently under investigation to improve the prognosis of this condition.


: L'hépatite alcoolique aiguë (HAA) se définit selon des paramètres essentiellement cliniques (ictère d'apparition récente chez un patient avec une consommation abusive d'alcool). L'HAA peu sévère est prise en charge par un sevrage éthylique, avec un espoir de survie de 90 % à un mois. Pour les patients atteints d'HAA sévère (évaluée par le score de Maddrey sup�rieur a 32, tenant compte de la bilirubine et du temps de prothrombine), un traitement par corticoïdes se discute, pour autant qu'une éventuelle infection ait pu être exclue ou jugulée. Le traitement par corticoïdes est poursuivi 28 jours si le score de Lille, calculé après 7 jours de corticoïdes, est favorable (inf�rieur a 0,45), avec un espoir de survie de 80-90 %. Par contre, si le score de Lille est défavorable (sup�rieur a 0,45), le pronostic est nettement plus péjoratif avec une survie de 25-30 % à 6 mois. Dans la prise en charge, on apportera une attention toute particulière à la nutrition avec un apport calorique suffisant. La transplantation hépatique, autrefois non autorisée dans cette indication, peut actuellement être discutée dans certaines circonstances particulières. La clé de la réussite résidera, de toute façon, dans le sevrage. Des médicaments novateurs sont actuellement en cours d'étude pour améliorer le pronostic de cette affection.

RESUMO

Acute mesenteric ischemia is a real life-threatening emergency. Mode of presentation is severe abdominal pain with sudden onset. The etiology is most of the time embolus coming from the heart or thrombosis of atherosclerotic vessel wall concerning the superior mesenteric artery. The best investigation is computed tomography with intravenous contrast media injection. Treatment consists of revascularization by open surgery or endovascular approach. Bowel resection may be necessary, as well as delayed second look surgery. This paper aims to review etiologies and therapeutics options for acute mesenteric ischemia.


L'ischémie mésentérique aiguë est une réelle urgence vitale. Elle se manifeste par une douleur abdominale sévère d'apparition brutale. Elle est, le plus souvent, provoquée par une embolie d'origine cardiaque ou une thrombose sur terrain athéroscléreux au niveau de l'artère mésentérique supérieure. Le meilleur examen complémentaire est la tomodensitométrie avec injection intraveineuse de produit de contraste. Le traitement consiste en une revascularisation par chirurgie ouverte ou technique endovasculaire. Une résection intestinale est ensuite parfois nécessaire, ainsi qu'une chirurgie différée de second look. Cet article a pour but de revoir les causes et les possibilités thérapeutiques de l'ischémie mésentérique aiguë.

RESUMO

Cystic echinococcosis or hydatidosis, is a zoonosis caused by larval stages of Echinococcus granulosus that can be encountered in Belgium in patients originating from endemic countries. The liver is the most commonly affected organ. In this paper, the authors describe the multidisciplinary management of this pathology based on the clinical case of a patient suffering from a 28 cm cystic echinococcosis treated by combination of albendazole and liver resection. Several treatment options are described in the literature although there is currently no clear consensus on the management of this condition.


L'échinococcose cystique, appelée aussi hydatidose, est une zoonose causée par le développement chez l'homme de la larve d'un ténia échinocoque de type Echinococcus granulosus. Il s'agit d'une pathologie cosmopolite qui peut être rencontrée en Belgique chez des patients originaires de pays endémiques et qui atteint, le plus souvent, le foie. Dans cet article, les auteurs discutent la prise en charge multidisciplinaire de cette pathologie en partant du cas d'un patient souffrant d'un kyste échinococcique hépatique de 28 cm traité par albendazole et résection hépatique. Plusieurs options de traitement de l'échinococcose cystique sont décrites dans la littérature bien qu'il n'existe pas, à l'heure actuelle, de consensus clair concernant la prise en charge de cette pathologie.

RESUMO

Alveolar echinococcosis is a zoonotic disease due to the tapeworm Echinococcus multilocularis. The definitive host is the red fox. Until recently, Belgium was considered a country at very low risk for alveolar echinococcosis. However, recent studies carried out in southern Belgium have revealed, through post-mortem examination, high prevalences (up to 62 %) in foxes. Cats and dogs can act as definitive hosts. Human are accidentally infected by ingestion of food contaminated by the feces. After a long incubation period, invasive hepatic lesions may appear, as well as extra-hepatic lesions. The disease may be fatal. The diagnosis is based on imaging techniques, serology and nucleic acid detection in tissues. Early diagnosis may allow surgical removal of the lesion associated with at least 2 years of albendazole postoperative treatment. In case of contraindication to surgery, a long term treatment with albendazole is necessary. Liver transplantation is sometimes necessary. This article presents the epidemiologic, clinical, diagnostic and therapeutics features of this zoonotic disease.


L'échinococcose alvéolaire est une zoonose due à Echinococcus multilocaris, un cestode, dont l'hôte définitif est le renard roux (Vulpes vulpes). Jusqu'il y a peu, la Belgique était un pays considéré comme à très faible risque pour cette parasitose, mais de récentes autopsies de renards ont montré des prévalences élevées chez ceux-ci (pouvant dépasser les 60 %). Les chiens et les chats peuvent également être des hôtes définitifs. La transmission humaine (hôte accidentel) se fait principalement via la consommation d'aliments souillés par les déjections animales contaminées donnant, après une longue période d'incubation, des lésions hépatiques infiltrantes et, éventuellement, des atteintes extra-hépatiques pouvant être mortelles. Le diagnostic est fondé sur l'imagerie médicale couplée à des tests sérologiques et la PCR sur des tissus. La prise en charge curative est chirurgicale, lorsque la résection complète est possible. Elle est associée à un traitement de deux ans post-opératoire à base d'albendazole. En cas d'impossibilité de résection complète, un traitement au long cours par de l'albendazole est préconisé. Enfin, dans certains cas, une transplantation hépatique peut être envisagée. En raison de l'augmentation des cas autochtones rencontrés en Wallonie, un groupe spécialisé dans la prise en charge de l'échinococcose a été créé au sein de l'université de Liège. Cet article illustre les caractéristiques épidémiologiques, cliniques, diagnostiques et thérapeutiques de cette zoonose.

RESUMO

BACKGROUND: Results of donation after circulatory death (DCD) liver transplantation are impaired by graft loss, resulting mainly from non-anastomotic biliary stricture. Donor age is a risk factor in deceased donor liver transplantation, and particularly in DCD liver transplantation. At the authors' institute, age is not an absolute exclusion criterion for discarding DCD liver grafts, DCD donors receive comfort therapy before withdrawal, and cold ischaemia is minimized. METHODS: All consecutive DCD liver transplantations performed from 2003 to 2012 were studied retrospectively. Three age groups were compared in terms of donor and recipient demographics, procurement and transplantation conditions, peak laboratory values during the first post-transplant 72 h, and results at 1 and 3 years. RESULTS: A total of 70 DCD liver transplants were performed, including 32 liver grafts from donors aged 55 years or less, 20 aged 56-69 years, and 18 aged 70 years or more. The overall graft survival rate at 1 month, 1 and 3 years was 99, 91 and 72 per cent respectively, with no graft lost secondary to non-anastomotic stricture. No difference other than age was noted between the three groups for donor or recipient characteristics, or procurement conditions. No primary non-function occurred, but one patient needed retransplantation for artery thrombosis. Biliary complications were similar in the three groups. Graft and patient survival rates were no different at 1 and 3 years between the three groups (P = 0.605). CONCLUSION: Results for DCD liver transplantation from younger and older donors were similar. Donor age above 50 years should not be a contraindication to DCD liver transplantation if other donor risk factors (such as warm and cold ischaemia time) are minimized.

RESUMO

Mesenchymal stromal cells (MSC) are multipotent and self-renewing cells. MSC are studied for their in vivo and in vitro immunomodulatory effects, in the prevention or the treatment of isehemic injury, and for their potential properties of tissue or organ reconstruction. Over the last few years, the potential role of MSC in organ transplantation has been studied both in vitro and in vivo, and their properties make them an ideal potential cell therapy after solid organ transplantation. A prospective, controlled, phase 1-2 study has been initiated at the CHU of Liege, Belgium. This study assesses the potential risks and benefits of MSC infusion after liver or kidney transplantation. Even if the preliminary results of this study look promising, solely a prospective, randomized, large scale, phase 3 study will allow the clinical confirmation of the theoretical benefits of MSC in solid organ transplantation.

RESUMO

BACKGROUND: Ileal conduit parastomal hernias (ICPHs) are frequent after radical cystectomy with ileal conduit urinary diversion, but their management is debated. This study aimed to review the results of ICPH repair according to Sugarbaker or Sandwich techniques, with special interest in ICPH recurrence and urological complications. METHODS: The authors reviewed a consecutive series of patients undergoing ICPH repair between January 2014 and December 2020. Primary endpoints were ICPH recurrences at clinical exam and cross-sectional abdominal computed tomography (CT) scans. Secondary endpoints were any other complications possibly related to the ICPH repair. RESULTS: Twenty-three patients underwent ICPH repair surgery (16 Sugarbaker and 7 Sandwich techniques) during the study period. Sixteen patients underwent a primary laparoscopic approach. All but one patient underwent at least one abdominal CT during the follow-up. Median clinical and CT scan follow-up times were 57 and 50.5 months, respectively. Clinical and CT ICPH recurrence rates were 4.5% and 13% at 5 years, respectively. Eighteen patients (78%) suffered no urological complications during the follow-up period, but three patients (13%) needed redo surgery on the urinary ileal conduit. CONCLUSION: The modified Sugarbaker or Sandwich techniques might be considered as promising techniques for ICPH repair with a low rate of recurrence. The urological complications, and particularly the ileal conduit-related issues, need to be evaluated in further studies. Controlled and prospective data are required to compare the Sugarbaker and Sandwich techniques to the Keyhole approach for ICPH repairs.

RESUMO

STUDY PURPOSE: The DRAGON 1 trial aims to assess training, implementation, safety and feasibility of combined portal- and hepatic-vein embolization (PVE/HVE) to accelerate future liver remnant (FLR) hypertrophy in patients with borderline resectable colorectal cancer liver metastases. METHODS: The DRAGON 1 trial is a worldwide multicenter prospective single arm trial. The primary endpoint is a composite of the safety of PVE/HVE, 90-day mortality, and one year accrual monitoring of each participating center. Secondary endpoints include: feasibility of resection, the used PVE and HVE techniques, FLR-hypertrophy, liver function (subset of centers), overall survival, and disease-free survival. All complications after the PVE/HVE procedure are documented. Liver volumes will be measured at week 1 and if applicable at week 3 and 6 after PVE/HVE and follow-up visits will be held at 1, 3, 6, and 12 months after the resection. RESULTS: Not applicable. CONCLUSION: DRAGON 1 is a prospective trial to assess the safety and feasibility of PVE/HVE. Participating study centers will be trained, and procedures standardized using Work Instructions (WI) to prepare for the DRAGON 2 randomized controlled trial. Outcomes should reveal the accrual potential of centers, safety profile of combined PVE/HVE and the effect of FLR-hypertrophy induction by PVE/HVE in patients with CRLM and a small FLR.
