Abstract
Objectives To analyse the efficacy of epilepsy surgery in reducing the burden of seizures in a paediatric population – a single centre 10 year experience.
Design Single centre retrospective review of medical records.
Subjects 74 consecutive paediatric patients who underwent epilepsy surgery between 2008–2017 by one neurosurgeon at a single centre.
Methods Seizure history, pre-operative investigations, surgical interventions, seizure outcomes, complications and long term anti-epileptic drug (AED) use were evaluated. Seizure outcomes at 1 year post surgery to the last available follow up (up to 5 years) were documented and classified using the Engel System. Engel I and II were classified as a good seizure outcome and Engel III and IV were classified as a poor seizure outcome.
Results The mean duration of follow up was 41 months. 62.2% of patients achieved seizure freedom (Engel I) at their latest follow up, with 82.4% of patients achieving a good seizure outcome (Engel I/II). 13.5% of patients achieved worthwhile improvement (Engel III) and only 4.1% of patients had no worthwhile improvement in seizure burden (Engel IV). More favourable outcomes were observed in children with temporal lobe epilepsy. Post-surgery AED use was reduced or discontinued in 41.4% of all patients; 41.4% of the 29 patients with AED data at their 5 year follow up were completely free of AEDs.
Conclusions Epilepsy surgery is an efficacious treatment with low morbidity and no mortality that is underutilised in children with medically intractable seizures.
