Accurate differentiation of dyssynergic defecation patients from normal subjects based on abnormal
anorectal angle in MR defecography
We aimed to study the differences between the dynamic indices of the pelvic floor, i.e. anorectal angle and perineal descent,
in dyssynergic defecation patients in comparison with healthy controls, based on MR Defecography. 22 constipated
patients with dyssynergic defecation and 14 healthy asymptomatic subjects were included in the study. 4 MR Defecography
dynamic indices, including paradox (abnormal anorectal angle change), perineal descent during straining, perineal ascent
and narrowing of anorectal angle at squeeze were measured in patients and healthy subjects. Paradox index had the highest
sensitivity (95.45%) and specificity (92.86%) for detection of dyssynergic defecation, with an R2 value of near 1 (0.902). The
sensitivity and specificity of other indices were not high; therefore, no significant improvement could be achieved using
other indices along with paradox index. Negative predictive value (92.85%) and Positive predictive value (95.45%) were only
high in paradox index. Paradox index was indicated to be the best finding of MR Defecography for identifying dyssynergic
defecation patients from healthy controls. Hence, MR Defecography could be exploited as a reliable tool to show the patients
the paradoxical function of their pelvic floor muscles, which could enhance their imagination of the correct defecation pattern
during their therapy.
