L\u2019\u00e9cho-endoscopie des voies a\u00e9riennes (EBUS) est un examen qui permet de r\u00e9aliser une ponction de ganglions m\u00e9diastinaux (situ\u00e9s dans le m\u00e9diastin, entre les 2 poumons).<\/strong> L\u2019examen n\u2019est pas douloureux. Il comporte certains risques tr\u00e8s rares et g\u00e9n\u00e9ralement sans gravit\u00e9 : r\u00e9action allergique \u00e0 la xyloca\u00efne (utilis\u00e9e pour l\u2019anesth\u00e9sie locale), saignements minimes, majoration de la difficult\u00e9 \u00e0 respirer, pneumothorax.<\/p>\n\n\n\n Le patient est hospitalis\u00e9 le matin de l\u2019examen en hospitalisation de jour. L\u2019examen dure entre 20 et 60 minutes et est r\u00e9alis\u00e9 par un pneumologue. Il se fait sous anesth\u00e9sie locale par xyloca\u00efne\u00ae, avec un masque permettant de respirer un gaz anesth\u00e9siant (le Kalinox\u00ae), apr\u00e8s une pr\u00e9m\u00e9dication administr\u00e9e par voie intra-veineuse 30 \u00e0 60 minutes avant l\u2019examen afin d\u2019\u00eatre d\u00e9tendu lors de la proc\u00e9dure . Dans des cas particuliers (anxi\u00e9t\u00e9 majeure et irr\u00e9ductible), il est possible de pr\u00e9voir une anesth\u00e9sie g\u00e9n\u00e9rale.<\/p>\n\n\n\n Durant l\u2019examen, il est possible de ressentir une impression d\u00e9sagr\u00e9able lorsque le tube passera au niveau des cordes vocales. Celle-ci n\u2019est que passag\u00e8re. Les biopsies ganglionnaires sont indolores. Le jeun est n\u00e9cessaire 1h30 apr\u00e8s la fin de l\u2019examen en raison de l\u2019anesth\u00e9sie locale.<\/p>\n\n\n\n Apr\u00e8s l\u2019examen, le patient b\u00e9n\u00e9ficie d\u2019une surveillance de quelques heures en hospitalisation de jour. Parfois une radiographie de thorax de contr\u00f4le s\u2019av\u00e8re n\u00e9cessaire. Les constatations faites par le pneumologue sont donn\u00e9es \u00e0 la fin de l\u2019examen.

C\u2019est actuellement l\u2019un des examens de r\u00e9f\u00e9rence pour connaitre la nature de ganglions du m\u00e9diastin.
Il permet \u00e9galement d\u2019effectuer des pr\u00e9l\u00e8vements afin de faciliter le diagnostic : aspiration des s\u00e9cr\u00e9tions bronchiques, et exploration proximale des voies a\u00e9riennes (trach\u00e9e et bronches).
L\u2019exploration se fait habituellement sous anesth\u00e9sie locale et pr\u00e9m\u00e9dication, avec un vid\u00e9o \u00e9cho endoscope (tube optique flexible coupl\u00e9e \u00e0 un \u00e9chographe permettant de rep\u00e9rer les ganglions) introduit par la bouche.<\/p>\n\n\n\nQue faut-il savoir ?<\/h3>\n\n\n\n
Comment \u00e7a se passe ?<\/h3>\n\n\n\n
Le patient doit \u00eatre \u00e0 jeun depuis 4 \u00e0 6 heures avant l\u2019examen et ne pas fumer 48 heures avant l\u2019exploration.<\/p>\n\n\n\n
La sortie de l\u2019h\u00f4pital de jour est autoris\u00e9e par le Pneumologue qui r\u00e9examine le patient quelques heures apr\u00e8s l\u2019examen au terme de la surveillance.<\/p>\n\n\n\nQuand aurai-je les r\u00e9sultats ?<\/h3>\n\n\n\n
Une premi\u00e8re lecture (examen extemporan\u00e9) des pr\u00e9l\u00e8vements est parfois r\u00e9alis\u00e9e lors du d\u00e9roulement de l\u2019examen par un m\u00e9decin anatomopathologique et peut donner des indications.
Les r\u00e9sultats d\u00e9finitifs des pr\u00e9l\u00e8vements seront communiqu\u00e9s entre 2 et 5 jours. Un compte-rendu d\u00e9taill\u00e9 est adress\u00e9 au m\u00e9decin traitant et peut \u00eatre adress\u00e9 \u00e9galement au patient.<\/p>\n","protected":false},"excerpt":{"rendered":"
