Preoperative treatment impact for ultralow rectal carcinoma sphincter preservation

摘要

Sphincter preservation for low rectal carcinoma must be evaluated with a plurifactoriel approach. Multicentric randomised studies are unable to demonstrate a relationship between complete tumoral response and conservative sphincteric rate. Intersphincteric resection technique is becoming a main factor to transform conservative indication. Complete tumoral response should not be the only purpose of future trials.
