Conclusions
L’EER, malgré son caractère opérateur dépendant, est moins coûteuse, plus rapide d’exécution que la RMNER et ses résultats sont plus précis que la TDM sauf pour les T4 et les tumeurs sténosantes. L’EER reste une aide à la décision thérapeutique malgré ses insuffisances… La contribution réelle d’une imagerie endorectale quelle qu’en soit la méthode, serait de pouvoir prédire la marge circonférentielle au nievau du mésorectum pour optimiser l’aide à la décision d’un traitement néoadjuvant et de ses modalités.
Conclusion
Despite its operator-dependent nature, TRUS is less expensive and more rapid than ERNMR. Results are more precise than with computed tomography excepting stenosing and T4 tumors. TRUS remains an important therapeutic decision-making tool despite its drawbacks. The real contribution of an endorectal imaging technique, irrespective of the method used, is its capacity to predict the circumference margin of the mesorectum in order to optimize neoadjuvant therapy and its modalities.
