Anal Sphincter Manometry and Electromyography

  • H. Blessing


According to Felt-Bersma et al. [15], “digital palpation is helpful in anorectal function investigation, but to establish exact anal pressures, anal manometry is mandatory.” Anal sphincter manometry, although not always necessary in proctological practice, has retained its significance mainly in the following clinical settings [11,14,16,20,29]:
  1. 1.

    Assessment of a potential high anal pressure situation in patients with hemorrhoids or anal fissures

  2. 2.

    Evaluation of anal sphincter incontinence

  3. 3.

    Sphincter reflex studies

  4. 4.
    Quality control
    1. a)

      After reconstructive anal sphincter surgery

    2. b)

      After biofeedback training of anal sphincter muscles
