Defecography effectively identifies rectal outlet obstruction in multiple sclerosis (MS) patients with constipation. The study found frequent puborectalis and anal sphincter muscle relaxation failure in these individuals.

Area of Science:

  • Gastroenterology
  • Neurology
  • Radiology

Background:

  • Intractable constipation is a common and debilitating symptom in patients with multiple sclerosis (MS).
  • Understanding the underlying anorectal dysfunction is crucial for effective management.

Purpose of the Study:

  • To assess the utility of defecography in evaluating anorectal function in MS patients experiencing severe constipation.
  • To identify specific defecographic findings associated with constipation in this population.

Main Methods:

  • Eleven patients with MS and constipation underwent defecography.
  • Barium contrast was used to visualize rectal and anal structures during defecation.
  • Video and static radiographic images were captured for analysis.

Main Results:

  • A significant proportion of patients exhibited inadequate puborectalis muscle effacement during defecation.
  • Complete or incomplete rectal emptying was observed in all participants.
  • Abnormalities such as intussusception and posterolateral pouch were noted in some patients.

Conclusions:

  • Defecography is a valuable tool for diagnosing rectal outlet obstruction in MS patients with constipation.
  • Failure of puborectalis and anal sphincter muscle relaxation is a common finding in this patient group.
  • These findings highlight the role of defecography in guiding treatment strategies for constipation in multiple sclerosis.
