| Research Abstract |
Reference values of anorectal examinations and endoanal ultrasonography have been obtained for Japanese population, which are categorized by gender and each decade of age between 20 and 90 years old. The anal canal is longer and both of the maximum resting pressure and the incremental voluntary squeeze pressure are higher in men than in women. Only the maximum resting pressure decreases with aging. Regarding the rectal balloon sensory examinations, no definite difference is observed depending on gender and age, whilst there is some tendency that the rectum is more sensitive in women than in men and that the sensation deteriorates with aging. The internal anal sphincter is thinner in men than in women, and thickens with aging, while there is no difference in its length depending on gender or age.
