Prevalence of sexual dysfunction in male cancer patients treated with rectal excision and coloanal anastomosis.

Impotency due to parasympathetic nerve injury is one of the most feared consequences of rectal cancer surgery. Sexual relationships make a significant contribution to the quality of life for almost everybody. Rectal excision and coloanal anastomosis (CAA) is a new surgical procedure for low rectal tumor with little data regarding the prevalence of sexual impairment as yet. We have examined the sexual life of 21 male patients who have undergone CAA by means a self-administered questionnaire. Only two patients reported reactive impotency. On the other hand 17 out of 21 patients had no ejaculation after undergoing surgery. According to our data it appears that CAA results in surgery a low degree of sexual impairment (impotency). Both sexual dysfunction and quality of life investigations should be integrated with oncological results when reporting data about colorectal surgery.
