[Redo surgery in children with epilepsy]

Area of Science:

• Neurosurgery
• Pediatric Neurology
• Epileptology

Background:

• Drug-resistant epilepsy in children often necessitates surgical intervention.
• Recurrent seizures after initial surgery indicate the need to evaluate redo procedures.

Purpose of the Study:

• To analyze the reasons for ineffective primary epilepsy surgeries.
• To evaluate the outcomes of redo surgery in pediatric patients with recurrent seizures.

Main Methods:

• Retrospective analysis of 41 children undergoing redo epilepsy surgery.
• Review of surgical histories, including temporal resection, extratemporal resection, multifocal resection, callosotomy, and stereotactic destruction.
• Assessment of outcomes using the Engel scale.

Main Results:

• Incomplete resection (56.1%) and inaccurate focus identification (36.6%) were primary causes of failure.
• Redo surgery typically involved extended resection (82.9%).
• Engel I outcome was achieved in 41.1% of patients at 3 years, decreasing to 36.4% at 10 years.

Conclusions:

• Redo surgery is an effective and minimally invasive option for children with recurrent epilepsy post-surgery.
• Patients with persistent seizures after initial interventions should be considered for repeat operations.
