Preoperative evaluation of rectal cancer
2001
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.
