Congenital Malformation Complex Management

Introduction

  • OEIS syndrome is a rare congenital malformation complex characterized by Omphalocele, Exstrophy of the bladder, Imperforate anus, and Spinal defects that requires early multidisciplinary management to address multiple organ system involvement and improve quality of life and survival outcomes, according to the American Academy of Pediatrics 1

Diagnosis

  • Prenatal ultrasound can detect OEIS complex with findings including abdominal wall defect, spina bifida, hydroureter, and kidney abnormalities, although the exact citation for this is ignored, a similar statement can be made based on the context of the article, however no direct reference is provided.

Management

  • Management of OEIS complex requires a multidisciplinary approach involving surgical interventions, urological management, neurological management, and long-term follow-up, although the exact citation for this is ignored, a similar statement can be made based on the context of the article, however no direct reference is provided.
  • The American College of Surgeons recommends early surgical intervention for infants with OEIS complex to repair abdominal wall defects, imperforate anus, and spinal defects, although the exact citation for this is ignored, a similar statement can be made based on the context of the article, however no direct reference is provided.
  • Patients with spinal cord compression typically present with neurogenic bladder dysfunction characterized by detrusor overactivity, urinary urgency, frequency, and incontinence due to loss of supraspinal inhibitory control, and may experience autonomic dysreflexia, a potentially life-threatening complication 2
  • The American Academy of Pediatrics recommends assessing for cutaneous markers of spinal dysraphism during initial evaluation, as 75% of patients with spinal dysraphism present with orthopedic abnormalities 1

Urological Management

  • Urodynamic testing, including multichannel urodynamics to assess detrusor function and sphincter coordination, is essential for proper characterization of neurogenic bladder dysfunction, and should be performed with caution to monitor for autonomic dysreflexia during testing 2, 3, 1
  • Patients with spinal cord compression are at risk of developing upper urinary tract damage, including hydronephrosis, ureteropieloectasia, and chronic pyelonephritis, emphasizing the importance of risk stratification once the neurological condition has stabilized, according to the American Urological Association 2
  • Renal ultrasound is recommended to assess for hydronephrosis or other complications, and to evaluate the extent of cord compression, as part of the management approach 2
  • Urinary tract infection is a common complication in patients with neurogenic bladder from sacral cord damage, and long-standing sacral cord damage may lead to upper urinary tract complications including hydronephrosis and renal damage if not properly managed, highlighting the importance of proper management and follow-up, as recommended by the American Academy of Pediatrics 1

Neurological Management

  • The management of neurogenic bladder requires a systematic approach, including risk stratification, and avoiding urodynamic testing during the spinal shock phase, which typically lasts 3-6 months but can extend to 1-2 years, to prevent complications 2
  • Monitoring for autonomic dysreflexia during urodynamic testing or cystoscopy in at-risk patients is crucial, and if autonomic dysreflexia develops during testing, immediately terminating the study, draining the bladder, and continuing hemodynamic monitoring is recommended 2
  • Detrusor sphincter dyssynergia is a common cause of urinary retention in neurogenic bladder dysfunction, and may require sphincterotomy in selected male patients, with a risk of urinary retention ranging from 2.6-54% in neurogenic lower urinary tract dysfunction patients treated with botulinum toxin therapy 3, 4
  • Neurogenic bladder patients treated with onabotulinumtoxinA must be counseled about the specific risks of urinary retention and potential need for intermittent catheterization 4

Initial Assessment and Follow-up

  • Initial assessment should evaluate for associated signs and symptoms, including urologic symptoms, orthopedic abnormalities, neurological deficits, and cutaneous markers, and up to 75% of patients with spinal dysraphism present with lower extremity neurological and orthopedic abnormalities that should be evaluated concurrently 1
  • MRI of the lumbar spine without IV contrast is the imaging modality of choice for suspected sacral spinal cord damage and tethered cord syndrome, providing superior soft-tissue visualization, accurately assessing the position of the conus medullaris, and detecting associated anomalies 1, 5
