Rectal prolapse and fecal incontinence are problems with enormous social, functional, and economic significance to hundreds of thousands of people every year. Through a knowledgeable approach and careful diagnostic studies, many people can be cured or helped.
OBJECTIVE: To determine whether 3D ultrasound examination of pelvic floor anatomy after vaginal delivery allows detection of childbirth trauma. STUDY DESIGN: Pelvic floor anatomy was examined in 16 women during the puerperium with a 3D transrectal ultrasound probe. Images were acquired via the vaginal route for the assessment of anal morphology and the transrectal route to determine paravaginal fixation. Images of the anterior pelvic floor were calculated from the information stored in the volume block. Paravaginal defect is defined as a descent of the lateral vaginal wall below the suburethral vagina, whereas sphincter defects are characterised as thinning, or as gap formation of the anterior part of the internal anal sphincter. RESULTS: This new approach allowed the examination of a horizontal plane through the urethra and the periurethral tissue which is inaccessible with 2D ultrasound techniques. Morphology of the normal and traumatised anal sphincter could be demonstrated using reference planes perpendicular to the anal canal. CONCLUSIONS: Whereas in the past, defects of the vaginal attachment to the pelvic side wall could not be examined sonographically, 3D ultrasound can now be used to examine pelvic floor anatomy and to detect changes associated with trauma to the pelvic floor following vaginal delivery.
OBJECTIVE AND IMPORTANCE: Idiopathic spinal cord herniation (ISCH) is a rare condition, reported in only 25 patients thus far, in which the thoracic cord is prolapsed through an anterior dural defect. It typically presents in middle age as either Brown-Sequard syndrome or spastic paraparesis. CLINICAL PRESENTATION: A 55-year-old woman initially presented at the age of 41 years with Brown-Sequard syndrome at the T8 disc space level on the left side. Investigations, including primitive magnetic resonance imaging, were deemed negative at that time. After a stepwise deterioration over 14 years, she presented again with spastic paraparesis and double incontinence, in addition to her previous spinothalamic dysfunction. Magnetic resonance imaging at this stage suggested either ISCH or a dorsal arachnoid cyst. INTERVENTION: Through a T7-T8 laminectomy, a left-of-midline ISCH was identified and easily reduced by gentle cord traction. No dorsal arachnoid cyst was identified. The anterior dural defect was repaired with a XenoDerm patch (LifeCell Corp., Woodlands, TX). After surgery, there was improved motor and sphincter function. However, there was continued sensory disturbance. CONCLUSION: ISCH is rare cause of thoracic cord dysfunction. Despite prolonged diagnostic delay, significant clinical improvement may be obtained with ISCH reduction and anterior dural repair.
