that are made based on manometry findings. for example, under part 2 (disorders of anal tone and contractility), listed manometric diagnoses include: anal hypotension, anal hypertension, anal hypercontractility and combined anal hypertension and hypercontractility. findings are also divided into: major findings, minor findings and inconclusive findings. major findings are findings that are not present in healthy patient such as rectoanal areflexia, minor findings are findings that are more commonly found in patients with anorectal disease compared to healthy patients, while inconclusive findings are findings that may be present in both groups. limitations centers rely on published data sets from healthy volunteers to evaluate test findings. however, the lack of standardization in equipment usage and procedural protocol, can in certain cases, impact the ability to determine what may be considered normal or abnormal values. this is further complicated by the limited amount of data on the 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.
