Résumé
Le choix du traitement optimal du cancer du rectum nécessite d’établir précisément le degré d’infiltration pariétale, le statut ganglionnaire et la présence de métastases à distance. Le bilan préopératoire permet de déterminer l’intérêt d’un traitement néoadjuvant et de choisir la technique chirurgicale, notamment en évaluant les possibilités d’exérèse locale. Les techniques d’imagerie les plus utiles dans ce contexte sont l’échoendoscopie endorectale, l’imagerie par résonance magnétique (IRM) et la tomodensitométrie.
Abstract
Information concerning the depth of tumour infiltration of the rectal wall and lymph nodes, and the presence of distant metastasis is crucial when planning a curative rectal cancer resection. Preoperative staging is used to determine if neoadjuvant therapy is indicated, as well as whether local excision or radical tumour resection will provide optimal surgical outcome. The most common imaging modalities currently used in the preoperative staging of rectal cancer are endorectal ultrasound, CT scan, and MRI.
