Summary

Physiologic testing aided diagnosis in half of severe constipation patients. History and symptoms did not predict which patients benefited most from these diagnostic studies.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Pelvic Floor Disorders

Background:

  • Severe constipation management often involves complex physiologic testing.
  • Understanding the diagnostic utility of these tests is crucial for patient care.

Purpose of the Study:

  • To evaluate the role of physiologic testing in diagnosing and directing treatment for severe constipation.
  • To assess the diagnostic accuracy and impact of various tests.

Main Methods:

  • Prospective review of 104 patients with severe idiopathic constipation who underwent physiologic testing.
  • Analysis of pretesting impressions, test results, and historical features.
  • Evaluation of diagnostic accuracy and impact on treatment plans.

Main Results:

  • Physiologic testing provided significant diagnostic information in 47% of patients with uncertain initial impressions.
  • Defecography and colonic transit times were identified as the most useful tests.
  • Prior hysterectomy, urinary incontinence, and pelvic outlet obstruction symptoms correlated with rectocele incidence.

Conclusions:

  • Physiologic testing is valuable, aiding specific diagnoses in approximately half of severe constipation cases.
  • Pretesting clinical information was insufficient to predict which patients would benefit most from these studies.
