Background:
Few studies have investigated the constipation or obstructed defecation symptoms identified by using imaging, as dynamic three-dimensional ultrasound and correlate vaginal delivery, parity, and age.
Objective:
The aim of this study was to assess the prevalence of pelvic floor dysfunctions in female patients with obstructed defection symptoms and to determine whether specific pelvic floor dysfunctions identified by dynamic three-dimensional ultrasonography (echodefecography) are correlated with vaginal delivery, parity, and age. The secondary goal is to report the prevalence of coexisting pelvic floor dysfunctions.
Methods:
This is a retrospective cohort study including patients with obstructed defecation symptoms underwent echodefecographyto evaluate pelvic floor dysfunctions in the posterior compartment and correlate with vaginal delivery, parity, and age.
Results:
Of 889 female: 552 (62%) had had vaginal delivery and 337 (38%) were nulliparous. The prevalence of dysfunctions identified by echodefecography (rectocele, intussusception, enterocele/sigmoidocele, and dyssynergia) was similar between the two groups and was not associated with number of deliveriesor age. However, the prevalence of sphincter defects showed higher rates in women with vaginal delivery and increased with the parity. Up to 33% of patients had coexisting dysfunctions.
Conclusion:
The prevalence of dysfunctions such as rectocele, intussusception, dyssynergia, and enterocele/sigmoidocele assessed by echodefecography in patients with obstructed defecation symptoms are found similar regardless of vaginal delivery, number of deliveries or stratified-age. In vaginal delivery, number of deliveries does impact on detection of sphincter defects and liability to fecal incontinence.
