A comparison of the usage of anal verge and dentate line in measuring distances within the rectum

Highlights • We use a vector subtraction approach to measure anorectal distances. • The majority of study subjects have three rectal valves. • Rectal valve topography is consistent across age and gender. • Measurements using anal verge and dentate line are comparable.
