[Anal sphincter replacement].

Presently, deep rectal carcinoma is usually treated by deep anterior rectal resection and colonal anastomosis. Abdominoperineal resection is needed only for the very few patients whose tumors infiltrate the pelvic base or sphincter musculature. This means the loss of normal anal function and thus of normal defecation. Many patients find the idea of a stoma unacceptable. In our experience, the construction of a functional neoanus after abdominoperineal rectal resection is a suitable option for patients in good general health and who are highly motivated.
