De nouvelles stratégies d’analyse endoscopique ont été développées pour explorer la paroi digestive bien au-delà de l’exploration endoscopique standard superficielle de la muqueuse. Parmi les techniques évaluées chez l’homme, les plus prometteuses sont l’optical frequency domain imaging et l’endomicroscopie confocale. Elles permettent une exploration mini-invasive du tube digestif en temps réel à l’échelon micro-scopique. Les outils ainsi développés, soit sous forme de capsules ingérables, soit de fibres passant par l’endoscope, ont pour but d’obtenir une véritable « histologie in vivo » morphologique et fonctionnelle. Au cours de cette revue, nous résumerons les principaux résultats obtenus dans différentes pathologies digestives telles que des maladies précancéreuses, inflammatoires et neuromusculaires.
Abstract
Novel endoscopic techniques for the analysis of the digestive wall have recently been developed to allow investigating digestive diseases beyond standard “white-light” macroscopic imaging of the mucosal surface. Among innovative techniques under clinical evaluation, confocal endomicroscopy and optical frequency domain imaging (OFDI) are the most promising. Indeed, these techniques allow performing in vivo microscopy with different levels in terms of depths and magnification, as well as functional assessment of structures. Some of these techniques, such as capsule-based OFDI, are also less invasive than traditional endoscopy and might help screening large groups of patients for specific disorders, for instance oesophageal precancerous diseases. In this review, we will focus on the results obtained with these techniques in precancerous, inflammatory and neuromuscular disorders.
