[Management of complicated Barrett's esophagus. Observational study carried out in a regional hospital]. / Prise en charge de l'œsophage de Barrett compliqué. Étude observationnelle réalisée dans un centre hospitalier régional.

The incidence of Barrett's esophagus, complication of gastroesophageal reflux disease, is rising in western countries. It is the same for esophageal adenocarcinoma, of which it is the main contributing factor. This retrospective study seeks to report the incidence of these pathologies observed in a regional hospital center and to describe their management. In 5 years, 354 Barrett's esophagus are detected and 34 of them are complicated by high-grade dysplasia or adenocarcinoma. Endoscopic resection is performed in 24 of these patients. The histological analysis of which leads to the conclusion of adenocarcinoma in 20 patients and high-grade dysplasia in the 14 others. The complications of endoscopic and surgical resections are detailed. Their frequency and severity remain low, comparable to data in the literature.

L'incidence de l'œsophage de Barrett, complication du reflux gastro-œsophagien, est en croissance dans les pays occidentaux. Il en est de même de l'adénocarcinome œsophagien dont il est le principal facteur favorisant. Cette étude rétrospective s'attache à rapporter l'incidence de ces pathologies, observées dans un centre hospitalier régional, et à détailler leur prise en charge. En 5 ans, 354 œsophages de Barrett sont détectés et 34 d'entre eux sont compliqués de dysplasie de haut grade ou d'adénocarcinome. Une résection endoscopique est réalisée chez 24 de ces malades. Les analyses histologiques permettent de conclure à un adénocarcinome chez 20 malades et une dysplasie de haut grade chez les 14 restants. Les complications des résections endoscopiques et chirurgicales sont détaillées. Leur fréquence et leur gravité restent faibles, comparables aux données de la littérature.

[Efficacy of macro-clips for perforations and fistulas following endoscopic or surgical procedures. Retrospective analysis of 25 consecutive cases]. / Les macro-clips utilisés dans la suture endoscopique des perforations et fistules compliquant des procédures chirurgicales et endoscopiques Résultats d'une étude monocentrique, rétrospective des 25 premiers cas.

OBJECTIVE: The aim of our retrospective study is to analyse the results of endoscopic macro-clips used for closing intestinal breaches in the real life. Post-endoscopic, spontaneous perforations and surgical fistulas are included. Our results are compared with principal published series. METHODS: Between 2010 and 2015, 25 consecutive patients underwent an endoscopic suture with macro-clips to seal a breach resulting from endoscopic perforation, surgical fistula, invasive medical procedure or spontaneous perforation. RESULTS: The endoscopic efficacy was immediate for all patients whose perforation was of endoscopic aetiology. None of them required surgery. Secondary complementary endoscopic treatment was only used in 6/25 patients. All of them had non-endoscopic aetiology for their perforation. The survival at 1 month was 84 % and at 3 months of 76 %. CONCLUSION: Our results confirm the high efficiency of macro-clips in the treatment of endoscopic breaches in a regional hospital center. The use of macro-clips seems less convincing for the closure of some postoperative fistula. The suture with macro-clips associated with endoscopic and medical treatments allowed to avoid surgical redo in some cases.

Objectifs : Le but de notre étude est d'analyser rétrospectivement les résultats obtenus en utilisant les macro-clips pour réaliser des sutures endoscopiques dans la vie réelle. Les perforations spontanées, postendoscopiques et post-chirurgicales sont incluses. Nos résultats sont comparés à ceux des principales séries publiées. Méthodes : Entre 2010 et 2015, 25 patients consécutifs ont bénéficié d'une suture endoscopique à l'aide de macro-clips utilisés pour fermer des larges brèches transmurales apparues après procédures endoscopiques, procédures chirurgicales ou invasives et, également, lors d'une perforation spontanée. Résultats : La fermeture endoscopique a été immédiate chez tous les patients dont la perforation avait pour origine une procédure endoscopique. Aucun de ces patients n'a requis d'intervention chirurgicale. Un second traitement endoscopique, complémentaire, a été réalisé chez 6/25 patients pour lesquels l'origine de la perforation n'était pas endoscopique. La survie globale à 1 mois était de 84 % et à 3 mois de 76 %. Conclusion : Nos résultats confirment l'efficacité remarquable des macro-clips dans le traitement des perforations endoscopiques rencontrées dans un centre hospitalier régional. Leurs résultats sont moins convaincants lorsqu'ils sont utilisés dans la fermeture des fistules post-chirurgicales. Ces macro-clips, utilisés dans une stratégie associant des traitements médicaux, radiologiques et endoscopiques complémentaires, permettent de réduire le recours à la reprise chirurgicale à de très rares cas.

[Acute cytomegalovirus proctitis in a immunocompetent patient]. / Rectite aiguë à cytomégalovirus chez un patient immunocompétent.

Cases of CMV proctitis are frequently reported in immunocompromised patients. However, some cases of CMV proctitis are linked to a CMV primary infection and to unprotected anal intercourse in immunocompetent patients. The most common symptom is bloody diarrhea (hemorrhagic colitis). The endoscopic exam can present in distincts forms. The diagnostic is based on a set of clinical, biological, endoscopic and histological arguments. The prognosis of the disease is favorable. The treatment is supportive. A research on other sexually transmitted diseases must be conducted.

Des cas de rectite à cytomégalovirus (CMV) sont fréquemment rapportés chez des patients immunodéprimés. Cependant, certains cas de rectite à CMV sont associés à une primo-infection à CMV et des rapports anaux non protégés chez une personne immunocompétente. La diarrhée hémorragique est le symptôme le plus fréquent. La présentation endoscopique est variée. Le diagnostic repose sur un faisceau d'arguments cliniques, biologiques, endoscopiques et histologiques. Le pronostic de l'affection est favorable. Le traitement est simplement supportif. Une recherche d'autres maladies sexuellement transmissibles doit être réalisée.

The Belgian national registry on chronic pancreatitis: A prospective multi-centre study covering more than 800 patients in one year.

BACKGROUND/OBJECTIVES: The epidemiology, natural history, complications, and therapeutic management of chronic pancreatitis (CP) are not well described at the national level. This multi-centre prospective observational study involving eight Belgian hospitals aimed to improve the understanding of these aspects of CP in Belgium. METHODS: All patients with a diagnosis of CP based on imaging were eligible for this study. Data were gathered regarding epidemiology, etiology, CP complications, and treatment modalities. RESULTS: A total of 809 patients were included between 1/9/2014 and 31/8/2015. Most patients (794) were adults ≥16-years old, 74% were male, the median age at symptom onset was 47 (38-57) years, the median disease duration was 7 (3-13) years, and the median Izbicki pain score (IPS) was 96 (0-195). The main etiological risk factors according to the TIGAR-O classification were alcohol and tobacco (67%). Current drinkers had lower body mass index (BMI) (21.4 kg/m2 vs 24.1 kg/m2), higher IPS (110 vs 56), and longer inability to work than non-drinkers. Current smokers had lower BMI (21.5 kg/m2 vs 25 kg/m2) and higher IPS (120 vs 30) than non-smokers. Endocrine insufficiency and/or clinical steatorrhea was recorded in 41% and 36% of patients, respectively. The highest IPS was reported in patients with ongoing endotherapy (166 vs 50 for patients who completed endoscopy). CONCLUSION: This multicentric study on CP patients showed that current alcohol drinking and smoking are associated with pain and malnutrition. Pain scores were higher in patients with ongoing endotherapy, independently of surgery.

[Incidence and treatment of complications observed after endoscopic mucosal resection of superficial digestive tumours in a regional general hospital]. / Incidence et traitement des complications observées après résections endoscopiques muqueuses des tumeurs digestives superficielles dans un Centre Hospitalier Régional.

Superficial digestive tumours resection by endoscopic mucosal resection and sub-mucosal dissection causes very few complications according to the results obtained in expert centers. This work reports the rate of complications observed in a regional hospital, also comparing the results of their therapeutic management. The first 100 patients treated by endoscopic mucosal resection and sub-mucosal dissection, conducted by conventional techniques, were studied. The usual complications (stenosis, bleeding, perforation) were identified and details of their treatment reported. The overall complication rate was 16 %. Symptomatic stenoses are observed in 4 % of patients. Secondary bleeding occurs in 5 % of cases. Endoscopic management of these complications is effective in all cases, when it is attempted. Perforations complicate 7 % of the procedures. Two patients were assigned to surgery, successfully, the other 5 patients were treated by endoscopic sutures without damage. The complication rates observed in our department are comparable with results reported by the reference western centers. Their endoscopic management is usually successful and rescue surgery is unfrequent.

La résection par mucosectomie et dissection sous-muqueuse des tumeurs digestives superficielles n'entraîne que très peu de complications selon les résultats obtenus dans les centres experts. Ce travail rapporte le taux de complications observé dans un centre hospitalier régional, comparant également les résultats de leur prise en charge. Les 100 premiers patients ayant été traités par mucosectomie et dissection sous-muqueuse, effectuées selon les techniques classiques, ont été étudiés. Les complications habituelles (sténoses, hémorragies et perforations) ont été répertoriées ainsi que les détails de leur traitement. Le taux global de complications est de 16 %. Les sténoses symptomatiques affectent 4 % des patients. Les hémorragies secondaires surviennent dans 5 % des cas. La prise en charge endoscopique de ces complications est efficace dans tous les cas, lorsqu'elle est tentée. Les perforations compliquent 7 % des procédures. Deux patients ont été confiés à la chirurgie, avec succès, les 5 autres patients ont été traités par sutures endoscopiques sans séquelle. Le taux de complications observé dans notre service est comparable aux résultats rapportés par les centres occidentaux de référence. Leur prise en charge endoscopique est régulièrement efficace et le recours à la chirurgie est peu fréquent.

[Hypercalcemia and acute renal failure: a case report of vitamin D intoxication]. / Le cas clinique du mois. Hypercalcémie et insuffisance rénale aiguë: un cas clinique d'intoxication à la vitamine D.

Vitamin D (VTD) deficiency has become a topical issue leading to screening with frequent supplementation. The latter can be dangerous and exceptionally causes overdoses. We report the case of a 20 year old patient with abdominal pain in the setting of hypercalcemia due to intoxication by VTD. This case offers the opportunity to describe the differential diagnosis of hypercalcemia and to brownse through the literature in search of clinical practice recommendations for VTD supplementation.

Pancreatic ectopia: a case report.

Pancreas ectopia / Ectopic pancreas (EP) is a rare congenital disease, most typically diagnosed in asymptomatic patients by incidental detection during surgery or at autopsy. It is defined by the presence of pancreatic tissue localized in various places drifting from the foregut or mesentery. It is subject to the same various inflammatory or neoplastic disorders that may affect the orthotopic pancreas, e.g. pancreatitis or pancreatic tumours. Upper GI endosonography is a key examination (tool) in detecting and defining gastroduodenal ectopic pancreas. However its diagnosis remains difficult. The final diagnosis relies on histopathologic analysis of the resected tumor required to confirm the diagnosis. Its treatment is based on patients' condition and symptoms as well as the kind of surgery depending on the location of the ectopic pancreatic tissue.

Rapid improvement of bone metabolism after infliximab treatment in Crohn's disease.

BACKGROUND: Crohn's disease is associated with low bone mineral density and altered bone metabolism. AIM: To assess the evolution of bone metabolism in Crohn's disease patients treated with infliximab. METHODS: We studied 71 Crohn's disease patients treated for the first time with infliximab for refractory Crohn's disease. Biochemical markers of bone formation (type-I procollagen N-terminal propeptide, bone-specific alkaline phosphatase, osteocalcin) and of bone resorption (C-telopeptide of type-I collagen) were measured in the serum before and 8 weeks after infliximab therapy and compared with values in a matched healthy control group. RESULTS: Eight weeks after treatment with infliximab, a normalization of bone markers was observed with a median increase in formation markers of 14-51% according to marker and a lower but significant decrease in resorption marker (median 11%). A clinically relevant increase in bone formation markers was present in 30-61% of patients according to the marker. A clinically relevant decrease in C-telopeptide of type-I collagen was present in 38% of patients. No association was found with any tested demographic or clinical parameter. CONCLUSION: Infliximab therapy in Crohn's disease may rapidly influence bone metabolism by acting either on bone formation or bone resorption. This improvement seems to be independent of clinical response to infliximab.

Hepatitis C of genotype 2: the role of medical invasive exams.

BACKGROUND AND AIM: Hepatitis C virus genotype 2 is the third in order of frequency in Belgium. The aim of this study was to better define the genotype 2 carriers' epidemiology characteristics. METHODS: In a database comprising 1726 viremic hepatitis C virus patient from the south part of Belgium, the files of 98 genotype 2 carriers were reviewed. RESULTS: There was a strong association between genotype 2 and the mode of transmission. The rate of contamination by invasive medical exams was very high (23%), and statistically different from the one of the others genotypes. Eligibility for antiviral therapies and the rate of sustained viral response were high. CONCLUSION: HCV genotype 2 was highly associated with transmission by invasive medical exams.
