, L'objectif de cette étude rétrospective monocentrique était d'évaluer l'apport diagnostique du coloscanner, en complément des résultats de l'IRM, chez des patientes ayant une suspicion clinique et/ou IRM d'atteinte digestive par endométriose

E. Mai, 92 patientes ont passé un coloscanner pour suspicion d'endométriose digestive, après une IRM réalisée dans le même centre ou dans un centre externe. Toutes les imageries des patientes incluses étaient relues en double aveugle par un radiologue sénior et un radiologue junior, afin de déterminer la présence d'une atteinte digestive transmurale ou non, et le cas échéant, sa localisation, ses dimensions et son éventuelle caractère sténosant ou multifocal, La sensibilité et spécificité de l'IRM et du coloscanner ont été calculées pour un sous-groupe de patientes opérées, 2017.

, La concordance inter-observateur était élevée en IRM et presque parfaite en coloscanner

, Cinquante-sept atteintes digestives « vraies », soit transmurales, ont été mises en évidence en IRM et la quasi-totalité d'entre elles (N=54, 94,7%) ont été confirmées en coloscanner

, Concernant les atteintes incertaines, c'est-à-dire qualifiées d' « indéterminées

. De-«-séreuses,

. Enfin, 34 lésions sténosantes ont été diagnostiquées en coloscanner avec une concordance inter-observateur presque parfaite

, Le coloscanner semble apporter une valeur ajoutée diagnostique sur le caractère transmural ou non de l'atteinte digestive endométriosique, notamment en ce qui concerne les cas douteux en IRM. Il semble également plus sensible pour le diagnostic de lésions multiples, notamment sigmoïdiennes et haut-situées ; et pour la détermination du caractère sténosant de la lésion. Néanmoins, ces résultats doivent être corrélés
