Summary

This review found no evidence on subpial transection for refractory epilepsy. More randomized controlled trials are needed to determine its benefits and risks for seizure control.

Area of Science:

  • Neurosurgery
  • Epileptology
  • Clinical Neurology

Background:

  • Refractory epilepsy affects nearly 30% of patients despite antiepileptic drug (AED) regimens.
  • Medically refractory epilepsy is defined as failure to respond to at least two AEDs.
  • Early surgical intervention may improve outcomes in children with uncontrolled epilepsy.

Purpose of the Study:

  • To evaluate the benefits and adverse effects of subpial transection surgery.
  • To assess subpial transection for partial-onset and generalized tonic-clonic seizures.
  • To include both pediatric and adult populations in the analysis.

Main Methods:

  • Searched Cochrane Epilepsy Group Register, CENTRAL, and MEDLINE up to August 2013.
  • Included randomized and quasi-randomized parallel group studies (blinded or non-blinded).

  • Two independent reviewers screened studies and planned data extraction and verification.
  • Main Results:

    • No relevant studies were identified for inclusion in this review.
    • The search yielded no randomized controlled trials or quasi-randomized studies on subpial transection for epilepsy.

    Conclusions:

    • There is currently insufficient evidence to support or refute subpial transection for medically refractory epilepsy.
    • High-quality randomized controlled trials are essential to guide future clinical practice.
    • Further research is needed to establish the efficacy and safety of this surgical procedure.
