[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.

[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.

New concept using Passive Infrared (PIR) technology for a contactless detection of breathing movement: a pilot study involving a cohort of 169 adult patients.

A pilot study has been conducted to validate the Breath Motion Detecting System (BMDS), a new concept using Passive Infrared (PIR) technology for a contactless detection of respiratory movements. The primary objective of the study was to show if movements detected during sleep by the BMDS were indeed related to breathing. This medical device is not intended to measure the respiratory rate, but in a second step, it will be able to detect pathological central apnea in adults. One hundred and sixty-nine adult patients underwent a full polysomnography in which each respiratory movement was recorded concomitantly through the BMDS. Curves obtained by the BMDS were compared to those of thoracic movements recorded by classical piezoelectric belts and of pressure obtained with nasal cannula. The correlations between the PIR sensors were highly indicative of respiratory movement detection. Since PIR sensors are sensitive only to the exemplification of the rib cage, they did not detect obstructive apnea. Unfortunately, only a few patients in the studied population had a central apnea. Moreover as our sleep laboratory was equipped only with piezoelectric bands, the central apnea respiratory effort data are not a validated signal to be used during sleep recordings. The data recorded by the BMDS demonstrate the ability of the PIR technology to detect respiratory movements in adults. The concept is practical, inexpensive and safe for the patient. Further studies with respiratory inductive plethysmography are needed to investigate the potential of BMDS to detect central apneas.

[Clinical case of the month. Liver transplantation for hepatic epithelioid hemangioendothelioma]. / Transplantation hépatique pour un hémangio-endothéliome épithélioïde du foie.

The epithelioid hemangioendothelioma is a rare malignant vascular lesion that may occur within the liver. In the hepatic multifocal and bilobar forms, liver transplantation is indicated as the curative management. In this case report, the authors describe the diagnosis and the management of a 52-year-old woman who was diagnosed with hepatic epithelioid hemangioendothelioma and who underwent successful liver transplantation.

[Paradox: when a prothrombotic disorder is responsible for an upper gastrointestinal bleeding. Case report of hepatoportal sclerosis]. / Paradoxe: lorsqu'un état prothrombotique est responsable d'une hémorragie digestive. Observation d'un cas de sclérose hépatoportale.

Variceal bleeding is frequently the initial presentation of a previously unknown cirrhosis. Portal hypertension and its complications without liver cirrhosis should raise the possibility of presinusoidal portal hypertension, and the diagnosis of hepatoportal sclerosis. These patients need to be investigated for coagulation disorders. A hypercoagulable state is often associated. Risks and benefits of anticoagulation should be further investigated in these patients.

The prevalence of colonic polyps in acromegaly: a colonoscopic and pathological study in 103 patients.

Patients with acromegaly are reported to be at risk of developing adenomatous colonic polyps, which are considered to be preneoplastic lesions. This assumption is, however, usually drawn from results obtained in rather small series of patients or without a control group. We, therefore, undertook a prospective colonoscopic and pathological study comprising 103 acromegalic patients and 138 nonacromegalic control subjects referred for irritable bowel syndrome. The prevalence of adenomatous colonic polyps was significantly increased in acromegalic patients compared to that in control subjects (22.3% vs. 8.0%; P = 0.0024). The significance was similarly present in male acromegalic patients (28.6% vs. 5.5% in male control subjects; P = 0.0026), but was absent in female acromegalic patients. The prevalence of colonic polyps was also significantly increased in the group of acromegalic patients under 55 yr of age (20.0% vs. 3.0% in the control group of the same age; P = 0.0026). Other characteristics of adenomatous colonic polyps in acromegaly were the multiplicity and the presence proximal to the splenic flexure. No difference in the duration of acromegaly was found between patients with or without adenomatous polyps. The prevalence of hyperplastic colonic polyps was also significantly increased to 24.3% in acromegalic patients vs 4.4% in control subjects (P < 0.001). In conclusion, in view of the increased incidence of adenomatous colonic polyps, colonoscopy should be part of the follow-up examination in acromegaly.
