Abstract
Background: Constipation is a prevalent condition in the general population that may be split into three categories: slow-transit constipation, normal-transit constipation, and defecatory disorders.
Objective: To research the function of dynamic MRI defecography in the identification of instances with blocked defecation and to separate patients who can undergo surgery from those who cannot.
Patients and Methods: There were 70 individuals with anorectal dysfunction in this prospective trial. Out of 70 patients, seven patients could not tolerate the examination and could not defecate during the dynamic scans. 63 participants were evaluated by study. Colonoscopy was done to exclude causes of obstruction.
Results: Regarding dynamic MRI defecography (MRD) finding, there were 48 patients (76.2%) had rectal descent where 2 patients (3.2%) were mild, 39 patients (61.9%) moderate and 7 patients (11.1%) were severe. Anterior rectocele was found in 32 patients (50.8%) where one patient (1.6%) was mild, 30 patients (47.6%) were moderate, and one patient (1.6%) was severe. Cystocele was diagnosed in 31 (49.2%) patients where 24 patients (38.1%) were mild, 7 patients (11.1%) were moderate and none of patient had severe cystocele. Rectal intussusception was found in 24 patients (38.1%). Puborectalis contraction (spasm) was recorded in 20 patients (31.7%). We found 5 patients (7.9%) didn’t recorded any abnormalities.
Conclusion: MRD has the ability in diagnosing subtle structural and functional abnormalities that could be overlooked during clinical examination which make it a reliable method of functional imaging of the pelvic floor dysfunction in general and anorectal dysfunction in particular.
