Anal sphincter manometry provides an objective assessment of one aspect of the anorectal sphincter mechanism. It provides a far more reliable indicator of anal sphincter tone than can be achieved by digital examination. The relative contribution of the voluntary and involuntary components can be assessed, and the integrity of reflex inhibition to rectal distention can be evaluated. Anal sphincter manometry may provide direct evidence of the underlying problem as in Hirschsprung's disease or anal sphincter hypertonia. Radial cross-sectional analysis can provide identification of surgically repairable segmental defects as in the case of traumatic injury. On the other hand, the finding of a normal anal sphincter profile may serve to redirect one's investigational efforts to other components of the sphincter apparatus.
肛门括约肌测压可对肛门直肠括约肌机制的一个方面进行客观评估。与指诊相比，它能提供更可靠的肛门括约肌张力指标。可评估随意和不随意成分的相对作用，并能评价对直肠扩张的反射抑制的完整性。肛门括约肌测压可为诸如先天性巨结肠或肛门括约肌张力亢进等潜在问题提供直接证据。如在创伤性损伤的情况下，径向横截面分析可识别可手术修复的节段性缺损。另一方面，肛门括约肌形态正常的结果可能有助于将研究工作转向括约肌装置的其他组成部分。
