Cauda equina syndrome: outcome and implications for management.

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Urology

Background:

• Cauda equina syndrome (CES) is a surgical emergency often caused by herniated lumbar discs.
• Timely surgical decompression is crucial for preserving neurological function and preventing long-term sequelae.

Purpose of the Study:

• To evaluate the impact of emergency versus delayed decompressive surgery on urological outcomes and quality of life in patients with CES.
• To compare outcomes between patients undergoing immediate surgery and those operated on the next available list.

Main Methods:

• Retrospective review of 20 patients (10 male, 10 female) with CES due to herniated lumbar disc treated between 1996 and 1999.
• Diagnosis confirmed by MRI (19 cases) or CT (1 case).
• Patients underwent laminectomy and discectomy, with surgery timing categorized as emergency (within 5 hours) or delayed (within 24 hours).

Main Results:

• No significant difference in urological outcomes or quality of life (assessed via questionnaire at mean 16 months post-surgery) between emergency and delayed surgery groups.
• Nine patients had emergency surgery; 11 had surgery on the next available list.
• A control group (laminectomy/discectomy without CES) showed 20% incidence of new postoperative urological symptoms.

Conclusions:

• Emergency decompressive surgery for CES did not significantly improve outcomes compared to a delayed approach.
• Surgical timing may not be the sole determinant of functional recovery in CES.
• Further research is needed to identify factors influencing CES outcomes.
