Multi-Institutional Review From the Pediatric Colorectal and Pelvic Learning Consortium of Minor Spinal Cord Dysraphism in the Setting of Anorectal Malformations: Diagnosis, Treatment, and Outcomes.

BACKGROUND/RATIONALE: Anorectal malformations (ARM) are associated with congenital anomalies of the spine, but the impact of a minor spinal cord dysraphism (mSCD) on fecal continence in the setting of ARM remains unclear. MATERIALS/METHODS: A retrospective review was performed utilizing data from the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) registry. The patient cohort was reviewed for ARM type, mSCD screening/incidence/neurosurgical intervention and age-based BMP utilization. RESULTS: 987 patients with ARM were categorized into mild (38%), moderate (32%) or complex (19%). 694 (70%) had normal spinal (NS) status. 271 (27.5%) patients had mSCD. MRI alone (49%) was the most common screening test for mSCD. US screening had a positive predictive value of 86.3% and a negative predictive value of 67.1%. Surgical intervention rates for mSCD ranged between 13% and 77% at a median age of 0.6-5.2 years. 726 (73.6%) patients were prescribed BMP (74.4% NS, 77.5% mSCD). Laxatives were most utilized BMP in all groups <5yo. ≥5yo, enema utilization increased with ARM complexity independent of spine status (with or without neurosurgical intervention). Neurosurgical intervention did not affect BMP utilization at any age or with any ARM when mSCD was identified. CONCLUSIONS: MSCD influence on bowel function in the setting ARM remains unclear. No significant impact of mSCD was noted on ARM patient bowel management program utilization. Variability exists within PCPLC site with screening and intervention for mSCD in patients with ARM. Future studies with standardized care may be needed to elucidate the true impact of mSCD on long term patient outcomes in ARM patients. TYPE OF STUDY: Retrospective Comparative Study. LEVEL OF EVIDENCE: III.

Spinal cord anomalies in patients with anorectal malformations without severe sacral abnormalities or meningomyelocele: outcomes after expectant, conservative management.

OBJECTIVE The goal of this study was to determine the significance of spinal cord anomalies (SCAs) in patients with anorectal malformations (ARMs) by comparing the outcomes for bowel function, lower urinary tract symptoms (LUTS), and lower-limb neurological abnormalities to these outcomes in patients with similar ARMs and a normal spinal cord. METHODS The spinal cord MRI records of female patients treated for vestibular and perineal fistula (VF/PF) and male patients with rectourethral fistula (RUF) at a single center between 1983 and 2006 were reviewed. Bowel function and LUTS were assessed by questionnaire. Patients with extensive sacral anomalies or meningomyelocele were excluded. RESULTS Of 89 patients (median age 15 years, range 5-29 years), MRI was available in 90% (n = 80; 40 male patients with RUF), and 80% of patients returned the questionnaire (n = 64; 31 male patients with RUF). Spinal cord anomalies were found in 34%, comprising a filum terminale lipoma in 30%, low conus medullaris in 10%, and thoracolumbar syrinx in 6%. Bowel functional outcomes between patients with SCAs (n = 23) and those with a normal spinal cord (n = 41) were not significantly different for soiling (70% vs 63%), fecal accidents (43% vs 34%), and constipation (57% vs 39%; p = not significant for all). The LUTS, including urge (65% vs 54%), urge incontinence (39% vs 24%), stress incontinence (17% vs 22%), and straining (32% vs 29%) were also comparable between groups (p = not significant for all). No patients developed lower-limb neurological abnormalities. CONCLUSIONS The results suggest that the long-term functional outcomes for patients with SCAs who had VF/PF and RUF may not differ significantly from patients with the same type of ARMs and a normal spinal cord. The results favor a conservative approach to their management in the absence of abnormal neurological findings in the lower limbs.

Spinal cord malformations.

Malformations of the spinal cord are one of the most frequent malformations. They should be clearly divided into two completely different families of malformations: open dysraphisms and occult dysraphisms. Open dysraphism mostly consists in myelomeningocele (MMC). Its incidence is 1/1000 live births with a wide variation. Folic acid supplementation has been shown to reduce its risk. In most cases, the diagnosis is done prenatally by serum screening and ultrasound and may lead to termination of pregnancy. In case of decision to continue pregnancy, surgical treatment must be achieved during the first days of life, and in 50 to 90% of cases, a ventricular shunt must be installed. The follow-up of these children must be continued throughout life looking for late complications (Chiari II and syringomyelia, vertebral problems, neuropathic bladder, tethered cord). Occult dysraphisms are a heterogeneous group of malformations. Lipomas (filum and conus) are the most frequent and their treatment remains controversial. Diastematomyelia, neurenteric cysts, dermal sinus, and more complex forms (Currarino syndrome) belong to this group. Most of them can and must be diagnosed prenatally or at birth by careful examination of the lower back for the cutaneous stigmata of the disease to decrease the risk of neurological, urological, or orthopedic permanent handicap.

Evaluation of anorectal function in patients with tethered cord syndrome: saline enema test and fecoflowmetry.

OBJECT: Disturbance in anorectal function is a major factor restricting the activities of daily living in patients with spinal cord disorders. To detect changes in anorectal motilities due to a tethered spinal cord, anorectal functions were evaluated using a saline enema test and fecoflowmetry before and after patients underwent untethering surgery. METHODS: The bowel functions in five patients with a tethered cord syndrome (TCS) were evaluated by performing a saline enema test and fecoflowmetry. The contractile activity of the rectum, the volume of infused saline tolerated in the rectum, anal canal pressure, and the ability to evacuate rectal content were examined. The characteristic findings in anorectal motility studies conducted in patients with TCS were a hyperactive rectum, diminished rectal saline-retention ability, and diminished maximal flow in saline evacuation. A hyperactive rectum was considered to be a major contributing factor to fecal incontinence. In one asymptomatic patient diminished anal squeezing pressure was exhibited and was incontinent to liquid preoperatively, but recovered after surgery. Two patients who underwent surgery for myeloschisis as infants complained of progressive fecal incontinence when they became adolescents. In one patient fecal incontinence improved but in another patient no improvement was observed after untethering surgery. CONCLUSIONS: Fecodynamic studies allow the detection of neurogenic disturbances of the anorectum in symptomatic and also in asymptomatic patients with TCS. More attention should be paid to the anorectal functions of patients with TCS.

[Laser reflexotherapy in the combined treatment of neurogenic bladder dysfunction in children with caudal regression syndrome]. / Lazerorefleksoterapiia v kompleksnom lechenii neirogennoi disfunktsii mochevogo puzyria u detei s sindromom kaudalnoi regressii.

The authors propose to introduce low-energy laser reflexotherapy to the complex of rehabilitative therapy for children with neurogenic dysfunction of the urinary bladder. The laser causes no pain, which enables the procedure to be used in infants, eliminates unretarded contractions of a detrusor rather effectively. A continuous reproduction of this therapeutic complex can be achieved by a relatively long-term stabilization of urination in a third of the children.

The role of the psychiatrist in myelodysplasia.

Management of the myelodysplasia patient and his family is best performed in the multidisciplinary setting of a comprehensive care clinic. Careful initial evaluation by each subspecialist on the team followed by family counseling provides the basis for selection of patients for treatment. Subsequently each subspecialist contributes up-to-date assessment and on-going medical care. Prevention of progressive orthopedic deformity through the use of plaster casts may minimize the need for surgical treatment. Severe deformities may require muscle balancing procedures. Aggressive surgical intervention is indicated in cases of progressive scoliosis and lordoscoliosis. Minimal urologic evaluation and surveillance guidelines have been developed, and prevention of irreversible renal damage is possible. Chemotherapy, adequate bladder drainage, and sophisticated techniques including sphincter and bladder electromyography and the use of artificial urinary sphincters and bladder pacemakers contribute to improved urologic management. The emotional needs of the patient and his family are complex, and support by the psychiatrist and the social worker as well as all other team members is necessary for adequate development of a well adjusted child in the face of physical handicaps.

Electronic bladder stimulation in spinal cord paralysis.

Authors performed electronic stimulation of the paralysed bladder that was attributed to various innervation troubles. For this purpose, they implanted 10 patients with stimulator Model PMS-3, each with 8 electrodes. In three cases, outside factors (like endocarditis, pyelonephritis aposthematosa, and progress of paralysis in the limbs) forced them to remove the stimulator. The other cases can be declared as successful, for complete bladder emptying has been obtained. The authors want to emphasize that patients with an implanted stimulator can dispense with an indwelling catheter thereby avoiding vesicoureteral reflux. The absence of recurrent pyelonephritis results in prolonged health. This new technique seems to be appropriate, especially in peripheric paralysis, while central paralysis connected with fibrosis of the bladder neck often requires additional surgical intervention, e.g. transurethral resection.
