Résumé
Les mini-sondes représentent une nouvelle voie en échoendoscopie digestive. De coût réduit, elles sont utilisables à volonté au cours de l’endoscopie diagnostique ou thérapeutique, puisqu’elles passent par les canaux opérateurs des endoscopes. Elles ont donné des résultats discordants dans l’exploration des sténoses tumorales du tube digestif, mais sont plus prometteuses pour l’étude des petits cancers en permettant la distinction entre cancer muqueux et cancer sous-muqueux. Dans les voies bilio-pancréatiques, les données de la littérature sont plus limitées. Elles paraissent d’un apport original dans l’évaluation des tumeurs ampullaires. L’exploration des sténoses de la voie biliaire principale, des cholangiocarcinomes ou de la pathologie du Wirsung est intéressante mais encore à confirmer.
Nul doute que la simplicité d’utilisation des mini-sondes, leur fiabilité croissante font prévoir un développement de cette méthode. L’adjonction de l’imagerie tridimensionnelle peut encore dans un futur proche renforcer son intérêt.
Summary
Miniprobes are a new way to perform digestive endoluminal sonography. Their cost is relatively low. They can be used during diagnostic or therapeutic endoscopy, as they can be passed through the operative channel of endoscopes. They gave discordant results for the staging of large stenosing carcinoma. They look more promising for the evaluation of «small cancer» allowing the distinction between mucosal and submucosal cancer. In the bilio-pancreatic ducts, scientific data are scarce. The method could be of great value in staging ampulloma. Exploration of stenosis of the bile duct, of cholangiocarcinomas or diseases of the pancreatic duct looks promising but has to be confirmed and its practical value has to be described.
No doubt however that the simplicity of use of miniprobes, their increasing fiability will boost this method in a near future. Tridimensional imaging capacities could increase even more the interest of this technique.
