Abstract
A 19-year-old man underwent resection at the S1–S2 interspace with sacrifice of bilateral sacral nerves below S2 for a sacral tumor. The postoperative anorectal function was evaluated periodically for one year using manometry and subjective findings. The rectoanal inhibitory reflex was intact, whereas a disturbance of anorectal sensation, a loss of anal squeeze pressure, a decrease of anal canal resting pressure, urinary incontinence, and impotency were apparent. These findings suggest that sacrifice of bilateral sacral nerves below S2 leads to a feeble anal canal basal tone with the rectoanal inhibitory reflex, and that a significant impairment of anorectal function is inevitable.
