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.

The incidence of pancreatic cancer has doubled during the past three decades. Pancreatic cancer is projected to become the second leading cause of cancer-related death by 2030. Overall 5-year survival is less than 10 %. It is thus of paramount importance to identify patients at risk to develop pancreatic cancer. The "pancreatic emergency route" and the weekly-organized complex surgery consultations are essential for fast and coordinated investigations for patients diagnosed of a pancreatic lesion. Pancreatic surgery, often preceded by neoadjuvant therapy, remains the only curative treatment if applicable. Implemented to decrease surgical morbidity and mortality, current centralization limits pancreatic resection surgery to a restricted numbers of expert centres in Belgium. Thanks to a close collaboration with the CHR of Liège, the CHR of Huy, the CHR of Bois de l'Abbaye, the Clinique André Renard and Vivalia, the reference centre of the CHU of Liège offers surgical, intensive, anaesthetic, oncological, gastroenterological, radiological and paramedical cares as part of a multidisciplinary approach characterized by expertise in the treatment of adenocarcinoma of the pancreas, 24 hours a day and 7 days a week.
L'incidence de l'adénocarcinome pancréatique a doublé lors des trois dernières décennies. Il devrait devenir la deuxième cause de mortalité par cancer en 2030. La survie globale est inférieure à 10 %. Il est essentiel d'identifier les patients à risque. La route «Urgences Pancréas¼ et les réunions hebdomadaires de concertation de chirurgie complexe assurent une prise en charge rapide et coordonnée pour les patients chez qui une lésion pancréatique suspecte est découverte. La chirurgie pancréatique, généralement précédée d'un traitement néoadjuvant, est la seule option à visée curative. Afin de diminuer la morbi-mortalité liée à cette chirurgie complexe, une convention de centralisation a été imposée par l'INAMI. Grâce à une étroite collaboration médico-chirurgicale regroupant le CHR de Liège, le CHR de Huy, le Centre Hospitalier du Bois de l'Abbaye, la Clinique André Renard et l'association intercommunale Vivalia, le centre de référence du CHU de Liège offre des soins chirurgicaux, intensifs, anesthésiologiques, oncologiques, radiothérapeutiques, gastro-entérologiques, radiologiques, infirmiers et paramédicaux de qualité et ce, dans le cadre d'une approche multidisciplinaire caractérisée par une expertise en matière du traitement de l'adénocarcinome du pancréas, 24 heures sur 24 et 7 jours sur 7.

Esophageal cancer is the 19th most common cancer in the European Union. Its prognosis remains poor with a 5-year survival rate estimated between 15 % and 25 %. Accurate diagnosis and pre-therapeutic assessment are essential and should allow a rapid start of therapy. Current treatment is based on multimodal management of which surgery remains the cornerstone. Since 2019, Belgium has started an agreement to centralize esophageal surgery in order to improve surgical outcomes. One year after implementation of centralization, our centre shows a low rate of severe complications (Clavien-Dindo classification IIIb-V) of 20 % and a 0 % mortality rate at 30 and 90 postoperative days. Our patients have benefited from a full minimally invasive or hybrid surgical procedure, contributing to those positive results. In the future, all our efforts must be done to improve collaboration between hospitals in order to provide best medical and surgical treatments.
Le cancer de l'oesophage est le 19ème cancer le plus fréquent dans l'Union Européenne. Son pronostic reste sombre avec un taux de survie à 5 ans estimé entre 15 % et 25 %. La précocité du diagnostic et la qualité du bilan pré-thérapeutique sont essentielles et doivent permettre d'initier un traitement rapide. Le traitement repose sur une prise en charge multidisciplinaire et multimodale dont la chirurgie reste la pierre angulaire. En Belgique, le taux de mortalité à 30 et 90 jours post-opératoires étaient de 4,1 % et 9,5 %, respectivement, pour la période allant de 2008 à 2016. Dans une perspective d'amélioration de cette prise en charge, depuis 2019, la Belgique a concentré la chirurgie de l'oesophage dans 10 centres de référence, incluant le CHU de Liège. Un an après centralisation, notre centre présente un taux de complications sévères selon Clavien-Dindo (IIIb-V) de 20 % et des taux de mortalité à 30 et 90 jours de 0 %. Le bilan d'évaluation initial de chaque patient est discuté en concertation multidisciplinaire. Une prise en charge nutritionnelle est discutée avant l'instauration du traitement. Tous nos patients bénéficient d'une approche systématique totalement mini-invasive ou hybride, participant à l'amélioration des résultats sur la morbidité et la mortalité. Une collaboration croissante avec nos hôpitaux partenaires permet d'harmoniser les mises au point et les plans de traitement oncologiques pour le bénéfice des patients.

Cystic lymphangioma is a rare and benign lymphatic malformation found most often in the first two years of life. Clinical manifestations are diverse and depend on size and site of the lesion. The most frequently affected sites are cervicofacial and axillary areas. The retroperitoneal form is rare. Diagnosis requires imaging but can only be confirmed on the basis of an anatomopathological examination. The treatment of choice is complete surgical removal. However, this is not always feasible due to proximity of vital structures. Some alternative therapies like sclerotic injection and oral drugs like immunosuppressive treatment or sildenafil are described. We report the case of a 62-year-old patient with retroperitoneal cystic lymphangioma successfully treated with sildenafil.
Le lymphangiome kystique est une malformation lymphatique rare et bénigne, découverte le plus souvent durant les deux premières années de vie. Les manifestations cliniques sont diverses et dépendent de la taille et de la localisation de la lésion. Les localisations les plus fréquentes sont cervicofaciale et axillaire. La forme rétropéritonéale est rare. Le diagnostic nécessite un bilan d'imagerie, mais ne peut être confirmé que sur base d'un examen anatomopathologique. Le traitement de choix est l'exérèse chirurgicale complète. Toutefois, celle-ci n'est pas toujours réalisable en raison de la proximité de structures vitales. Certains traitements alternatifs comme la sclérothérapie ou l'administration de traitements oraux tels qu'immunosuppresseurs ou sildénafil sont décrits. Nous rapportons le cas d'un patient âgé de 62 ans avec lymphangiome kystique rétropéritonéal traité avec succès par sildénafil.

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.

INTRODUCTION: Potassium abnormalities are frequent in intensive care but their incidence in the emergency department is unknown. AIM: We describe the spectrum of potassium abnormalities in our tertiary-level pediatric emergency department. METHODS: Retrospective case-control study of all the patients admitted to a single-center tertiary emergency department over a 2.5-year period. We compared patients with hypokalemia (<3.0mEq/L) and patients with hyperkalemia (>6.0mEq/L) against a normal randomized population recruited on a 3:1 ratio with potassium levels between 3.5 and 5mEq/L. RESULTS: Between January 1, 2013 and August 31, 2016 we admitted 108,209 patients to our emergency department. A total of 9342 blood samples were tested and the following potassium measurements were found: 60 cases of hypokalemia (2.8±0.2mEq/L) and 55 cases of hyperkalemia (6.4±0.6mEq/L). In total, 200 patients with normokalemia were recruited (4.1±0.3mEq/L). The main causes of the disorders were non-specific: lower respiratory tract infection (23%) and fracture (15%) for hypokalemia, lower respiratory tract (21.8%) and ear-nose-throat infections (20.0%) for hyperkalemia. Patients with hyperkalemia had an elevated creatinine level (0.72±1.6 vs. 0.40±0.16mg/dL, P<0.0001) with lower bicarbonate (19.4±3.8 vs. 21.8±2.8mmol/L, P=0.0001) and higher phosphorus levels (1.95±0.6 vs. 1.42±0.27mg/dL, P=0.0001). Patients with hypokalemia had an elevated creatinine level (0.66±0.71 vs. 0.40±0.16mg/dL, P<0.0001) and a lower phosphorus level (1.12±0.31 vs. 1.42±0.27mg/dL, P=0.0001). We did not observe significant differences in pH, PCO2, base excess and lactate, or in the mean duration of hospitalization in general wards and pediatric intensive care units according to the PIM and PRISM scores. DISCUSSION: Dyskalemia is rare in emergency department patients: 0.64% for hypokalemia and 0.58% for hyperkalemia. This condition could be explained by a degree of renal failure due to transient volume disturbance. The main mechanism is dehydration due to digestive losses, polypnea in young patients, and poor intake. In the case of hypokalemia, poor intake and digestive losses could be the main explanation. These disorders resolve easily with feeding or perfusion and do not impair development. CONCLUSION: Dyskalemia is rare in emergency department patients and is easily resolved with feeding or perfusion. A plausible etiological mechanism is a transient volume disturbance. Dyskalemia is not predictive of poor development in the emergency pediatric population.

Ever since the initial description of the Milan criteria, used for selecting patients with hepatocellular carcinoma (HCC) for liver transplantation (LT), there has been a clear need to go further than solely morphological criteria. Tumours exceeding the Milan criteria, but presenting favourable biological behaviour, might still allow for comparable overall- and disease-free survivals after LT. As it is well established that the presence of microvascular invasion is a major factor that influences HCC recurrence after LT, several serum and tissue biomarkers in addition to imaging studies are attracting wider attention as more refined tools for selecting HCC patients for LT. A thorough review of the recent literature on the subject was conducted. In the future a combination of systemic inflammation markers, biomarkers and morphological criteria may be key to more accurate prediction of HCC recurrence after LT. This may allow LT in patients whose HCC tumours exceed the Milan criteria but have favourable biological behaviour. Further prospective studies are required in order to improve patient selection for transplantation in HCC and these could help a move towards more transparent and improved management.

Hereditary diffuse gastric cancer is a form of gastric cancer associated, in about 40 % of cases, with a germline mutation of the CDH1 gene. The management of patients with a pathogenic mutation of this gene is based on total prophylactic gastrectomy because, until proven otherwise, endoscopic monitoring is insufficient. We report a series of eight patients with pathogenic CDH1 mutation who underwent total prophylactic gastrectomy in our centre.
Le cancer gastrique diffus héréditaire est une forme de cancer gastrique associé, dans 40 % des cas environ, à une mutation germinale du gène CDH1. La prise en charge des patients porteurs d'une mutation pathogène de ce gène repose sur la gastrectomie totale prophylactique car, jusqu'à preuve du contraire, la surveillance endoscopique est insuffisante. Nous rapportons une série de huit patients porteurs d'une mutation pathogène de CDH1 ayant bénéficié d'une gastrectomie totale prophylactique dans notre centre.

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.

BACKGROUND: Acute kidney injury (AKI) in the intensive care unit is associated with significant mortality and morbidity. OBJECTIVES: To determine and update previous recommendations for the prevention of AKI, specifically the role of fluids, diuretics, inotropes, vasopressors/vasodilators, hormonal and nutritional interventions, sedatives, statins, remote ischaemic preconditioning and care bundles. METHOD: A systematic search of the literature was performed for studies published between 1966 and March 2017 using these potential protective strategies in adult patients at risk of AKI. The following clinical conditions were considered: major surgery, critical illness, sepsis, shock, exposure to potentially nephrotoxic drugs and radiocontrast. Clinical endpoints included incidence or grade of AKI, the need for renal replacement therapy and mortality. Studies were graded according to the international GRADE system. RESULTS: We formulated 12 recommendations, 13 suggestions and seven best practice statements. The few strong recommendations with high-level evidence are mostly against the intervention in question (starches, low-dose dopamine, statins in cardiac surgery). Strong recommendations with lower-level evidence include controlled fluid resuscitation with crystalloids, avoiding fluid overload, titration of norepinephrine to a target MAP of 65-70 mmHg (unless chronic hypertension) and not using diuretics or levosimendan for kidney protection solely. CONCLUSION: The results of recent randomised controlled trials have allowed the formulation of new recommendations and/or increase the strength of previous recommendations. On the other hand, in many domains the available evidence remains insufficient, resulting from the limited quality of the clinical trials and the poor reporting of kidney outcomes.

In recent years, the treatment of esophagus cancer has been completely changed, thus competing the dogma of surgery as the cornerstone treatment. Multimodality treatments as radio-chemotherapy directly followed by surgery, or delayed surgery, significantly improve patient survival compared to surgery alone. Neoadjuvant radiochemotherapy is associated with a higher complete pathologic response rate and improved survival compared to chemotherapy alone. Immediate surgery after radio-chemotherapy is challenged for patients who present a complete clinical response, especially in case of squamous cell carcinoma. Indeed, systematic resection is associated with a significant postoperative mortality rate and has not proven any survival advantage in complete clinical responders as opposed to delayed resection in case of locally persistent or recurrent disease. In squamous cell carcinoma, this could lead to organ preservation, thus avoiding the mortality and durable functional impairment of esophagectomy. This review will discuss the positioning of the multimodality treatment strategy with neoadjuvant radiochemotherapy and chemotherapy and also the strategy of organ preservation.
Depuis quelques années, le traitement du cancer de l'Åsophage est en pleine mutation, bousculant ainsi le grand dogme de la chirurgie comme pierre angulaire du traitement. Par rapport à la chirurgie seule, les traitements multimodaux de radiochimiothérapie suivis, directement ou de façon différée, par la chirurgie améliorent significativement les chances de survie prolongée des patients. Comparée à la chimiothérapie néodjuvante, la radiochimiothérapie néoadjuvante démontre un taux de réponse pathologique complet plus élevé qui résulte en une survie prolongée. Chez les très bons répondeurs cliniques, la question de la place de la résection chirurgicale d'emblée est remise en question, surtout pour les carcinomes épidermoïdes. Chez ces patients, la résection systématique par rapport à un acte différé n'offre pas d'avantage en survie, expose le patient à un risque de mortalité significatif alors qu'un certain nombre de patients n'auront jamais à être opérés. Le seul bénéfice actuellement démontré de la résection est une amélioration du contrôle local; or, le devenir du patient est principalement lié à la récidive métastatique. Dans cette revue, nous positionnons et discutons la place des différents traitements multimodaux, chimiothérapie et radiochimiothérapie néoadjuvantes, ainsi que la place de la préservation d'organe par rapport à une chirurgie d'emblée après une radiochimiothérapie.

Esophageal cancers represent a highly heterogeneous entity mixing two different tumour types : AdenoCarcinoma (ADC) and Squamous Cell Carcinoma (SSC). Developing in the same organ, they are very often considered as a unique pathology and, consequently, the same therapeutic strategy is indiscriminately applied. Esophageal cancer treatments are particularly complex and require a multidisciplinary approach. Despite impressive advances in the tumour statidifaction, surgery, radiotherapy and chemotherapy, the overall prognosis remains grim even at an early stage of the disease. In order to improve the treatment of esophageal cancers and the patientâ™s survival, we need to consider that ADC and SCC represent two different pathologies requiring specific therapeutic strategies. This review in two parts will present recent data from clinical trials under the scope of tumour histology to set up dedicated therapeutic strategies. In this first part, we explain the restricted role of surgical resection, the prognostic factors and the results of exclusive combined chemotherapy and radiation in localized esophageal cancer.
Les cancers de l'Åsophage concernent deux entités d'histologie et de pathogenèse différentes : les carcinomes épidermoïdes (CE) et les adénocarcinomes (ADC). Ils se développent dans un même organe et sont souvent considérés comme une seule et unique maladie avec, comme conséquence, une stratégie thérapeutique identique. Leur traitement est complexe et requiert une prise en charge multidisciplinaire. Bien que les techniques de mise au point de la pathologie, de traitement par chirurgie, de radiothérapie et de chimiothérapie se soient améliorées, le pronostic de la maladie reste péjoratif, même à un stade précoce. L'amélioration de la prise en charge et de la survie des patients nécessite de considérer les CE et les ADC comme deux pathologies distinctes, impliquant des approches thérapeutiques qui leur soient spécifiquement dédiées. Cette revue en deux parties analyse les différents aspects thérapeutiques des cancers de l'Åsophage sous l'angle de l'histologie et permet de dégager des stratégies spécifiques. Cette première partie est consacrée aux limites de la résection chirurgicale, aux facteurs pronostiques et aux résultats des traitements par radio-chimiothérapie exclusive des cancers localisés.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is increasingly used in patients with severe respiratory failure. Indirect calorimetry (IC) is a safe and non-invasive method for measuring resting energy expenditure (REE). No data exist on the use of IC in ECMO-treated patients as oxygen uptake and carbon dioxide elimination are divided between mechanical ventilation and the artificial lung. We report our preliminary clinical experience with a theoretical model that derives REE from IC measurements obtained separately on the ventilator and on the artificial lung. METHODS: A patient undergoing veno-venous ECMO for acute respiratory failure due to bilateral pneumonia was studied. The calorimeter was first connected to the ventilator and oxygen consumption (VO2 ) and carbon dioxide transport (VCO2 ) were measured until steady state was reached. Subsequently, the IC was connected to the membrane oxygenator and similar gas analysis was performed. VO2 and VCO2 values at the native and artificial lung were summed and incorporated in the Weir equation to obtain a REEcomposite . RESULTS: At the ventilator level, VO2 and VCO2 were 29.5 ml/min and 16 ml/min. VO2 and VCO2 at the artificial lung level were 213 ml/min and 187 ml/min. Based on these values, a REEcomposite of 1703 kcal/day was obtained. The Faisy-Fagon and Harris-Benedict equations calculated a REE of 1373 and 1563 kcal/day. CONCLUSION: We present IC-acquired gas analysis in ECMO patients. We propose to insert individually obtained IC measurements at the native and the artificial lung in the Weir equation for retrieving a measured REEcomposite .

BACKGROUND: Solid pseudopapillary tumor of the pancreas (SPTP) is a rare pancreatic neoplasm. The aim of this study was to discuss the clinical presentation, management, and outcome of patients with this kind of tumor. MATERIALS AND METHODS: A retrospective review was performed in 6 patients with SPTP surgically treated between January 2004 and September 2011 in our hospital. RESULTS: All the 6 patients were female. The mean age of the patients was 39 years (range, 18 to 67 years). The main clinical presentation was abdominal pain or discomfort, however a third of the patients were asymptomatic. The mean size of the tumor was 9.7 cm (range, 2.5 to 18 cm). Three tumors had a well defined capsule, 3 tumors extended in the pancreas. Four of the 6 tumors had a cystic component, and calcifications were observed in one tumor. No lymph node involvement, no lymphatic invasion and no nerve invasion were observed. One tumor showed an infiltration of the splenic vein, and another patient had a liver metastasis with complete resection. Distal pancreatectomy (n = 3), local resection (n = 1), cephalic duodenopancreatectomy (n = 1), and distal pancreatectomy associated with a right hepatectomy (n = 1) were performed. The main postoperative complication in the short-term was bleeding (n = 1), and long-term the development of an insulin-requiring diabetes (n = 2). No patient received adjuvant therapy. Overall mortality rate was 0%. All patients were still alive without recurrent disease with a median follow up of 36.2 months. CONCLUSION: Patients with SPTP have an excellent prognosis after its complete removal, even if it is a minimized resection.

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.

Anti-N-methyl-D-aspartate receptor (NMDA-R) encephalitis is a severe form of encephalitis that has been identified within the context of acute neuropsychiatric manifestations. We report the case of an 18-year-old adolescent referred for a first episode of acute psychosis. The clinical picture rapidly deteriorated to a state of catatonia, decreased consciousness and autonomic instability. Detection of highly positive anti-NMDA-R antibodies confirmed the diagnosis of anti-NMDA-R encephalitis. Immunosuppressive treatment and repeated plasma exchange resulted in slow recovery. The literature on diagnosis and treatment of this specific type of encephalitis is reviewed.

PURPOSE: The purpose of this study was to evaluate short and long term results after esophageal cancer resection in patients older than 75. METHODS: We retrospectively analyzed the database of esophageal cancer surgically treated in our department between January 2003 and December 2009 to identify patients older than 75. The preoperative, operative, postoperative and long term characteristics were analyzed. RESULTS: Among 137 patient, 23 were older than 75. The histological subtype was adenocarcinoma in 100%. The surgical techniques were a "Lewis-Santy" procedure in 43%, a trans-hiatal resection in 22%, a "Sweet" procedure in 13%, a stripping in 13% and a McKeown procedure in 9%. The in-hospital postoperative mortality was 13%. The in-hospital postoperative morbidity (Dindo-Clavien Grade >2, deceased patients included) was 26%. In univariate analysis, no statistically significant risk factor of morbidity was found. A Charlson Comorbidity Index >2 was, in univariate analysis, the sole risk factor of postoperative mortality (p = 0.0362). The mean hospital stay was 22 +/- 12 days. The median survival was 24.2 months. The 5-year overall survival was 39% and the 5-year disease free survival was 26%.57% of long-term deaths were not cancer related. CONCLUSION: Esophageal surgery performed in selected patients older than 75 has an acceptable morbidity and mortality but when a severe complication occurs, it leads to death in half of the cases. Surgery enables a long term survival benefit. This study confirmed our attitude of not considering age as a contra-indication for esophageal surgery but rather considering general status, self-reliance and associated comorbidities for patients' selection.

INTRODUCTION: End-stage renal disease is a major public health problem in Viet Nam. A cooperative project between the University of Liège, Belgium, and the University of Medicine Pham Ngoc Thach, Ho Chi Minh City, Viet Nam, has permitted the establishment of an autonomous program of renal transplantation from living-related donors at the Peoples' Hospital No 115. The aim of this paper was to report the primary results of the project and to draw conclusions for the future. PATIENTS AND METHODS: From January 2004 to July 2008, we performed 33 living-related renal transplantations. Mean ages of donors and recipients were 31.8 ± 9.5 and 41.6 ± 13.5 years, respectively. Laparoscopic nephrectomy was performed in 6 donors. The immunosuppressive regimen consisted of three drugs associated with induction therapy using anti-interleukin-2 receptor monoclonal antibody. RESULTS: The 33 donors are in good health at follow-up. Four developed major intra- or postoperative hemorrhage necessitating transfusion, with a surgical re-exploration in 1 donor. Wound infection occurred in 2 donors. Posttransplant recipient and graft survivals at 1 versus 3 years were 82% and 73% versus 82% and 65%, respectively. Eight recipients presented 13 biopsy-proven acute rejection episodes that were reversible in 7, but 1 patient lost his graft due to an irreversible rejection. Two recipients developed cancer. CONCLUSIONS: These initial results have encouraged us to continue the program of renal transplantation from living-related donors. However, they also pointed out the need to develop other donor sources.

Cystic lymphangioma of the mesentery is a benign condition, probably of malformative origin, and frequently appearing in infancy. Its symptomatology can be very polymorphic. Its diagnosis is suspected by ultrasonography and computed tomography, and definitely confirmed by pathology. About a recent case of cystic lymphangioma of the mesentery diagnosed and operated on at the university hospital of Liège in an adult patient, the authors review its classification and its therapeutic strategy. Surgical resection is indicated in symptomatic cystic lymphangioma.

Fatigue is today the most common and incapacitating side effect in patients treated with cytotoxic drugs. Fatigue affects both physical and psychosocial function and reduces the patients' quality of life. The symptom severity is dependent on cancer type, cytotoxic drugs given and doses, comorbidity and the presence and severity of other symptoms like pain, insomnia, depression, anxiety, diarrhea. Risk factors also include female gender and young age. The mechanisms explaining fatigue is still mostly unknown and there is no general treatment to alleviate the symptoms, although effective treatment of coexisting symptoms and easy exercise will make some benefit. The present survey discusses the pathophysiology and epidemiology of fatigue as well as gives information on its biochemical mechanisms. This also opens up for new targets for treatment.
