Low inserted median arcuate ligament may cause extrinsic coeliac trunk compression and median arcuate ligament syndrome (association of post-prandial epigastric pain, weight loss and nausea or vomiting). In liver transplantation, liver graft arterial supply depends on the recipient's hepatic artery, as the gastro-duodenal artery has generally been ligated. A decreased graft arterial flow caused by coeliac trunk stenosis might induce hepatic artery thrombosis leading to graft loss. In this short report the authors describe a liver transplant procedure during which recipient's hepatic artery pressure was dramatically decreased after ligature of the gastro-duodenal artery. Dissection and division of the median arcuate ligament allowed to restore an excellent blood flow through the hepatic artery. This report reminds how important it is to be able to recognize and how to manage a stenosing median arcuate ligament in liver transplantation. [less ▲]

INTRODUCTION: Small bowel obstruction (SBO) is a common presentation to emergency abdominal surgery. The most frequent causes of SBO are congenital, postoperative adhesions, abdominal wall hernia, internal hernia and malignancy. PATIENTS: A 27-year-old woman was hospitalized because of acute abdominal pain, blockage of gases and stools associated with vomiting. Abdominal computed tomography showed an acute small bowel obstruction without any obvious etiology. In view of important abdominal pain and the lack of clear diagnosis, an explorative laparoscopy was performed. Diagnostic of pelvic inflammatory disease was established and was comforted by positive PCR for Chlamydia Trachomatis. RESULTS: Acute small bowel obstruction resulting from acute pelvic inflammatory disease, emerging early after infection, without any clinical or X-ray obvious signs was not described in the literature yet. This infrequent acute SBO etiology but must be searched especially when there is no other evident cause of obstruction in female patients. Early laparoscopy is mostly advised when there are some worrying clinical or CT scan signs. [less ▲]

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. [less ▲]

Introduction: Until now, Belgium has been considered as a low-risk country for alveolar echinococcosis (AE). However it was recently demonstrated by necropsy series that up to 51% of the red foxes (Vulpes vulpes) may be infected by E. multilocaris in some parts of Southern Belgium. The first local Belgian human AE cases were described in the early 2000's. Aim: The aim of this study was to report the experience of a tertiary university hospital of Southern Belgium with AE management. Methods: The authors retrospectively collected data from the parasitology laboratory (serologies), the hospital pharmacy in charge of supplying albendazole, and by searching through patient’s files with medico-economic information service of a tertiary university hospital. The medical files were retrospectively reviewed. Results: Twenty-one cases (66% male) of local AE have been recorded from 1999 to 2016. All patients were Belgian citizens with more than 30 years of life in Southern Belgium (Liege province: 10 cases (47.4%), Luxembourg province: 8 cases (36.8%), Namur Province: 3 cases (15.8 %)). Mean age of diagnosis was 66 years (ranges: (35-85y). Eighteen patients had hepatic involvement: 14 underwent surgical resection and 5 had unresectable liver lesions and underwent albendazole palliative therapy until death. During the same period, the faculty of veterinary medicine observed an increased rate of lethal hepatic AE in dogs, another indication of high AE incidence. Conclusions: AE appears to be spreading in Belgium and has actually an uneven geographical distribution with endemicity in areas of Southern and Eastern Belgium. However, it is probable that local AE cases will be diagnosed in the whole country, considering that there is no reason that infected foxes remain in Southern Belgium and also the fact that some people from Northern Belgium might spend long period in Southern Belgium, with or without their dogs. The liver is the most frequently involved organ and the only cure can be achieved by complete R0 resection of all AE lesions. In reaction to this experience, the authors created a multidisciplinary group for AE diagnosis and management, including hepatologists, infectiologists, microbiologists, pathologists, radiologists, nuclear medicine specialists, surgeons and veterinarians. The authorities should be aware of this medical issue and should facilitate the access to Albendazole for AE patients. A complete national survey should be encouraged, and BASL might have an important role in this study. [less ▲]

Positron emission tomography computed tomography (PET-CT) using 18-Fluoro-deoxyglucose (18FDG) is an imaging modality that reflects cellular glucose metabolism. Most cancers show an uptake of 18FDG and benign tumors do not usually behave in such a way. The authors report herein the case of a 38-year-old female patient with a past medical history of cervical intraepithelial neoplasia and pheochromocytoma, in whom a liver lesion had been detected with PET-CT. The tumor was laparoscopically resected and the diagnosis of inflammatory hepatic adenoma was confirmed. This is the first description of an inflammatory hepatic adenoma with an 18FDG up-take.

Kidney transplantation (KTx) represents the best available treatment for patients with end-stage renal disease. Still, the full benefits of KTx are undermined by acute rejection (AR). The diagnosis of AR ultimately relies on transplant needle biopsy. However, such an invasive procedure is associated with a significant risk of complications and is limited by sampling error and interobserver variability. In the present review, we summarize the current literature about non-invasive approaches for the diagnosis of AR in kidney transplant recipients (KTRs), including in vivo imaging, gene-expression profiling and omics analyses of blood and urine samples. Most imaging techniques, such as contrast-enhanced ultrasound and magnetic resonance, exploit the fact that blood flow is significantly lowered in case of AR-induced inflammation. In addition, AR-associated recruitment of activated leucocytes may be detectable by 18F-fluorodeoxyglucose positron emission tomography. In parallel, urine biomarkers, including CXCL9/CXCL10 or a three-gene signature of CD3ε, CXCL10 and 18S RNA levels, have been identified. None of these approaches has yet been adopted in the clinical follow-up of KTRs, but standardization of analysis procedures may help assess reproducibility and comparative diagnostic yield in large, prospective, multicentre trials.

Crohn's disease is a chronic inflammatory condition characterized by recurrent and/or chronic lesions, leading to cumulative structural bowel damage. It is established that the correlation between symptoms and intestinal lesions is weak. Therefore, monitoring by frequent cross-sectional imaging is proposed to assess the disease activity. There is no consensus about the preferred imaging option. Priority is given to non-radiating modalities, such as ultrasonography and MRI. Tomodensitometry will be reserved for emergency cases. Ultrasonography can be useful, in emergency as well as for the monitoring of lesions of known topography. Entero-MRI is henceforth considered the standard imaging technique for the diagnosis and follow-up of Crohn's disease. Its high contrast resolution allows an accurate assessment of disease activity, therapeutic efficacy, cumulative structural bowel damage and complications. [less ▲]

Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited disease characterised by the progressive development of multiple and bilateral cysts in kidneys and other organs. Most patients with ADPKD will develop, sooner or later, end-stage renal disease (ESRD). The morbidity and mortality associated with ESRD prompt physicians to identify early ADPKD patients considered as «rapid progressors», who have the greatest risk to rapidly develop ESRD. The rate of progression can be assessed by clinical - especially with the «predicting renal outcome in polycystic kidney disease score» (PROPKD-Score) -, biological (a decline of the glomerular filtration rate (GFR) of 4,4 - 5,9 ml/min/year and/or the doubling of serum creatinine within a 36-month period), or radiological criteria (total kidney volume (TKV) adjusted for the size > 600 cc/m and/or TKV annual growth rate > 5 %). Nowadays, there is no curative treatment for ADPKD. However, vasopressin-2 receptor antagonists, such as tolvaptan, appear to slow down the growth of renal cysts and the slope of GFR decline. The current management of ADPKD patients is mostly based on correcting the risk factors for progression, i.e. encouraging (over)-hydration, normalizing blood pressure, stimulating smoking cessation.

Crohn's disease (CD) is a chronic inflammatory bowel disease which mainly affects young people. This disease evolves in successive steps and is often complicated by strictures which express characteristic signs of occlusive syndrome, more often in case of ileal than colonic involvement. The nature and localisation of strictures should be precisely defined by different techniques like endoscopy, entero-(colo)-scanner or entero-(colo)-MRI. This work-up is essential to best adapt the therapeutic care. Indeed, the fibrosing evolution of inflammatory strictures causes medical treatment's failure which may lead to endoscopic dilatation or surgical resection. To avoid this negative evolution, it is mandatory to adopt early therapeutic strategy to control inflammation. [less ▲]

To date, the mutational status of EGFR and PTEN has been shown as relevant for favoring pro- or anti-tumor functions of STAT3 in human glioblastoma multiforme (GBM). We have screened genomic data from 154 patients and have identified a strong positive correlation between STAT3 and HDAC7 expression. In the current work we show the existence of a subpopulation of patients overexpressing HDAC7 and STAT3 that has particularly poor clinical outcome. Surprisingly, the somatic mutation rate of both STAT3 and HDAC7 was insignificant in GBM comparing with EGFR, PTEN or TP53. Depletion of HDAC7 in a range of GBM cells induced the expression of tyrosine kinase JAK1 and the tumor suppressor AKAP12. Both proteins synergistically sustained the activity of STAT3 by inducing its phosphorylation (JAK1) and protein expression (AKAP12). In absence of HDAC7, activated STAT3 was responsible for significant imbalance of secreted pro-/anti-angiogenic factors. This inhibited the migration and sprouting of endothelial cells in paracrine fashion in vitro as well as angiogenesis in vivo. In a murine model of GBM, induced HDAC7-silencing decreased the tumor burden by threefold. The current data show for the first time that silencing HDAC7 can reset the tumor suppressor activity of STAT3, independently of the EGFR/PTEN/TP53 background of the GBM. This effect could be exploited to overcome tumor heterogeneity and provide a new rationale behind the development of specific HDAC7 inhibitors for clinical use. [less ▲]

AIM: To evaluate the prognostic value of pretreatment FDG positron emission tomography computed tomography (PET-CT) in patients with hepatocarcinoma treated by liver transplantation (LT). METHODS: The authors retrospectively analyzed the data of 27 patients (mean age 58 +/- 9 years) who underwent FDG PET-CT before LT for hepatocarcinoma. Mean follow-up was 26 +/- 18 mo. The FDG PET/CT was performed according to a standard clinical protocol: 4 MBqFDG/kg body weight, uptake 60 min, low-dose non-enhanced CT. The authors measured the SUVmax and SUVmean of the tumor and the normal liver. The tumor/liver activity ratios (RSUVmax and RSUVmean) were tested as prognostic factors and compared to the following conventional prognostic factors: MILAN, CLIP, OKUDA, TNM stage, alphafoetoprotein level, portal thrombosis, size of the largest nodule, tumor differentiation, microvascular invasion, underlying cirrhosis and liver function. RESULTS: Overall and recurrence free survivals were 80.7% and 67.4% at 3 years, and 70.6% and 67.4% at 5 years, respectively. According to a multivariate Cox model, only FDG PET/CT RSUVmax predicted recurrence free survival. Even though the MILAN criteria alone were not predictive, it is worth noting that none of the patients outside the MILAN criteria and with RSUVmax < 1.15 relapsed. CONCLUSION: FDG PET/CT with an RSUVmax cut-off value of 1.15 is a strong prognostic factor for recurrence and death in patients with HCC treated by LT in this retrospective series. Further prospective studies should test whether this metabolic index should be systematically included in the preoperative assessment. [less ▲]

INTRODUCTION: Deep remission including clinical remission and tissue healing has been advocated as the therapeutic target in Crohn's disease. Yet, the definition of deep remission remains unclear. The aim of this study was to assess the persisting lesions at magnetic resonance enterocolonography (MREC) in clinically quiescent Crohn's disease as well as their relapse predictive value. METHODS: we performed a prospective monocentre cohort study. We included patients with clinical remission. At baseline, these patients had blood tests, the measurement of fecal calprotectin and underwent a MREC. They were then followed up clinically for a minimum of 1 year. A relapse was defined by a HBI > 4 with an increase of at least 3 points. Correlations between clinical, demographic, biological parameters and MREC signs were assessed as well as the time-to-relapse predictive value of the studied variables. RESULTS: Twenty seven patients were recruited. Fourteen out of 27 had persisting disease activity at MREC. MREC signs only partly correlated with biomarkers. Ten out of 27 patients relapsed over a median follow up of 25 months. In univariate analysis, relative contrast enhancement of the most affected segment (HR: 2.56; P = 0.046), ulcers (HR: 12.5; P = 0.039), fistulas (HR: 14.1; P = 0.009) and target sign (HR: 3.63; P = 0.049) were associated with relapse. In multivariate analysis, fistula was the only one. CONCLUSIONS: Half of the patients with clinically quiescent Crohn's disease had persisting signs of disease activity at MREC. These signs predicted time-to-relapse. [less ▲]

Pancreatic ductal adenocarcinoma is characterized by a high rate of early metastatic relapse. Surgical resection is still recognized as the cornerstone upfront therapy. However, reported 5 years survival rates are inferior to 20-25% even when surgery is followed by chemotherapy. Margins involvement on the surgical specimen (50 to 85%) and lymph node involvement (around 70%) both strongly impact survival. Median survivals are close to those of locally advanced diseases treated by chemotherapy or chemoradiotherapy, 15 to 16 months. This review focuses on adverse prognostic factors, post-operative outcomes and their impact on multimodality therapy completion rates and survivals in patients undergoing upfront surgery. Current data and emerging results from neoadjuvant series could lead to a change in the therapeutic strategy. [less ▲]
