Actualización con la clasificación de Londres en la interpretación de la manometría anorrectal de alta resolución

High resolution anorectal manometry is a diagnostic tool, used for anorectal motor and sensory disorders. It consists of a measurement of basal tone and anal contraction, it also performs the push maneuver, rectoanal inhibitory reflex (RAIR) and rectal sensory parameters. The conventional interpretation of anorectal manometry focuses on describing in isolation the dysfunctional anatomical region. However, with the London classification It`s sought to standardize the report of these results, grouping them into major, minor disorders and inconclusive findings, like to the Chicago`s classification for esophageal motor disorders.
