Abstract

DELGADO VILLARREAL, Andrés et al. Update of high-resolution anorectal manometry interpretation using the London classification. Rev Col Gastroenterol [online]. 2019, vol.34, n.4, pp.411-415. ISSN 0120-9957.  https://doi.org/10.22516/25007440.484.

High resolution anorectal manometry is a diagnostic test, used for anorectal motor and sensory disorders. It consists of measurement of basal tone, anal contraction and squeeze, the rectoanal inhibitory reflex (RAIR), and rectal sensory parameters. The conventional interpretation of anorectal manometry focuses on describing the dysfunctional anatomical region in isolation. However, the London classification seeks to standardize the report of these results, grouping them into major, minor and inconclusive findings in a manner similar to the Chicago classification for esophageal motor disorders.

Keywords : Anorectal manometry; anorectal functional disorders; anorectal physiology; London classification.
