impact of different epidemiological characteristics (such as age or gender) on said values. For an individual patient, findings on anorectal manometry, alone, does not dictate management. In addition to correlating manometry findings with clinical findings, as part of a diagnostic or evaluatory workup, the use of anorectal manometry may be complemented with other diagnostic tests such as endoanal ultrasound, defecography or gut transit studies. High resolution anorectal manometry also experiences pressure drift, variable linear changes in pressure readings over time, that could impact the clinical value of manometry findings in some specific situations.
