[Preoperative evaluation of rectal cancer].
For a patient with a rectal tumor, the preoperative staging should answer four questions: Is the rectal tumor unique? Is the patient operable? Are there distal metastases? What is the loco-regional extension? The loco-regional extension is well evaluated by the echo-endoscopy while the involvement of the surrounding organs is better assessed by CT-scan or resonance magnetic imaging.
