Study of the role of dynamic pelvic mri defecography in evaluation of patients with chronic constipation

Background: Patients with obstructed defecation syndrome (ODS) form an important subset of patients with chronic constipation. Evaluation of these patients has traditionally been difficult. Magnetic resonance defecography (MRD) is a very useful tool for the evaluation of these patients. Patients and Methods: 30 patients with chronic idiopathic constipation (according to Rome III) wereselected, (17 males, 13 females) with mean age 37 years.Conventional clinical diagnosis, Ileo-colonoscopy and laboratory investigation focus on excluding all potential organic causes of patient symptoms, Agachan constipation score questionnaire were completed and Dynamic MRI defecography was performed. The different pelvic floor morphology was recorded. Results: The dynamic pelvic MRI defecography showed 26 patients with pelvic floor descent, 14 Rectal prolapse,17 anterior rectocele , 8peritoneocele , 4 uterine prolapse, and 3 dyskinetic puborectalis muscle and the mean value of total Agachan score was 16. Conclusions: Magnetic resonance defecography is an effective method for evaluation of pelvic floor weakness and anorectal dysfunction. With no ionizing radiation, less than 30 minutes of imaging, and complete anatomic and functional details.
