Summary

Biofeedback retraining for anismus can fail, particularly in patients with a long history of dyschezia. Pre-treatment testing for associated pelvic disorders is not essential for predicting biofeedback success.

Area of Science:

  • Gastroenterology
  • Pelvic Floor Disorders
  • Biofeedback Therapy

Background:

  • Biofeedback is a primary treatment for anismus-induced dyschezia.
  • Treatment failure in anismus can stem from co-occurring pelvic floor disorders.
  • Identifying predictors of biofeedback failure is crucial for optimizing patient outcomes.

Purpose of the Study:

  • To identify indicators of biofeedback failure in patients undergoing treatment for anismus.
  • To determine if associated pelvirectal disorders predict biofeedback retraining outcomes.

Main Methods:

  • Twenty-seven patients with anismus and dyschezia unresponsive to laxatives underwent biofeedback retraining.
  • Diagnostic assessments included proctologic examination, anal manometry, and defecography.

  • Patient data were analyzed to compare characteristics between those who responded and those who did not respond to biofeedback.

    • Main Results:

    • Biofeedback retraining failed to resolve dyschezia in 48% of patients (13 out of 27).
    • Associated pelvirectal disorders and specific past medical histories did not significantly predict treatment failure.
    • A significantly longer duration of symptoms prior to treatment (81 months vs. 33 months) was observed in patients unresponsive to biofeedback (P < 0.01).

    Conclusions:

    • Extensive pre-treatment investigations like defecography and manometry are not mandatory for predicting biofeedback failure in anismus.
    • A prolonged history of dyschezia appears to be a key indicator of potential biofeedback retraining failure.
    • The findings suggest focusing on symptom duration rather than associated disorders for predicting treatment outcomes.
