Dyssynergic defecation, a common cause of chronic constipation, involves poor rectoanal coordination. Diagnosis uses clinical evaluation and physiologic tests, with neuromuscular conditioning and biofeedback therapy showing treatment promise.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Pelvic Floor Dysfunction

Background:

  • Dyssynergic defecation affects 50% of patients with chronic constipation.
  • Significant overlap exists between dyssynergic defecation and slow transit constipation.
  • The primary mechanism is a failure of rectoanal coordination.

Purpose of the Study:

  • To outline diagnostic methods for dyssynergic defecation.
  • To discuss current and potential therapeutic strategies.
  • To highlight the need for refined diagnostic criteria and rehabilitation programs.

Main Methods:

  • Diagnosis relies on patient history and prospective stool diaries.
  • Detailed clinical evaluation is essential.
  • Anorectal physiologic tests aid in identifying the condition.

Main Results:

  • Dyssynergic defecation can be diagnosed using a combination of clinical and physiologic assessments.
  • Biofeedback therapy is a promising treatment, with controlled trials ongoing.
  • Neuromuscular conditioning and biofeedback therapy can manage most patients.

Conclusions:

  • Accurate diagnosis of dyssynergic defecation is achievable through comprehensive evaluation.
  • Neuromuscular conditioning and biofeedback therapy offer effective management options.
  • Further research into diagnostic criteria and therapy refinement is warranted for improved patient outcomes.
