Evaluation of obstructed defecation syndrome (ODS) using magnetic resonance defecography (MRD)

Abstract Background Obstructed defecation syndrome is associated with varying combinations of a host of ano-rectal abnormalities, and no physical examination can demonstrate these abnormalities. The present study was aimed to evaluate the spectrum of various pelvic floor abnormalities in obstructed defecation syndrome (ODS). Results Of the total 302 patients imaged with age range of 18–72 years (mean age 54 years), 218 were females, and 84 were males. Ano-rectal junction descent was the commonest abnormality observed in 273 (90.3%) patients followed by rectocele (232) (76.8%), rectal intussusception (93) (30.7%), and cystocele (92) (30.4%). Cervical descent was observed in 78 (35.7%) of female patients. Spastic perineum was seen in 27 (8.9%) patients. Conclusion MRD serves as single stop shop for demonstrating and grading a gamut of pelvic organ abnormalities underpinning ODS which in turn helps in choosing the best treatment plan for the patient.
