Insights
Epilepsy surgery can improve seizure control and cognitive function in children with intractable epileptic encephalopathy (EE), including Lennox-Gastaut syndrome (LGS). This surgical intervention offers significant benefits for managing severe childhood epilepsy.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Epileptology
Background:
- Intractable epileptic encephalopathy (EE) presents significant challenges in pediatric populations.
- Epilepsy surgery is an established treatment modality for refractory epilepsy.
Purpose of the Study:
- To evaluate the efficacy and role of epilepsy surgery in children diagnosed with intractable epileptic encephalopathy (EE).
- To assess seizure control and cognitive outcomes following surgical intervention for EE.
Main Methods:
- A retrospective analysis of 95 children with intractable EE who underwent epilepsy surgery between 2003 and 2008.
- Surgical procedures included lobar resection, hemispherotomy, and corpus callosotomy (CC).
- Patients were categorized into Lennox-Gastaut syndrome (LGS) (n=76) and West syndrome (n=19).
Main Results:
- Engel's class I outcomes (seizure freedom) were achieved in 61.5% of LGS patients and 60.0% of West syndrome patients undergoing specific resections.
- Postoperative cognitive function improved in 19 of 27 LGS patients.
- Malformations of cortical development were observed in 73.5% of cases.
Conclusions:
- Epilepsy surgery is a viable treatment option for children with intractable EE, offering potential for seizure and cognitive improvements.
- Consideration of surgical intervention is warranted even for challenging cases like Lennox-Gastaut syndrome.
- Shorter epilepsy duration and successful seizure control correlate with better intellectual outcomes.
Purpose:
to evaluate the outcomes and role of epilepsy surgery in children with intractable epileptic encephalopathy (EE).
Methods:
ninety-five children (64 boys, 31 girls) with intractable EE were treated by epilepsy surgery at Severance Children's Hospital from 2003 to 2008. Surgical treatments included lobar resection, hemispherotomy and corpus callosotomy (CC). Seventy-six children were Lennox-Gastaut syndrome (LGS), and 19 had West syndrome.
Results:
of the 76 patients with LGS, CC was performed in 37 patients (48.7%), lobar resection in 29 (38.2%) and hemispherotomy in 10 (13.2%). Of the 19 patients with West syndrome, respective surgery was performed in 15 patients (78.9%) and CC in 4 (21.1%). Of the patients receiving respective surgery, Engel's class I outcomes were achieved for 24 of 39 (61.5%) of LGS patients, and for 9 of 15 (60.0%) of West syndrome. Malformations of cortical development were commonly observed, appearing in 73.5% (36/49). In neuropsychiatric tests, 19 of 27 with LGS demonstrated improvement in postoperative cognitive function. More significant intellectual improvement correlated well with shorter epilepsy duration, good seizure outcomes, and decreased number of antiepileptic drugs.
Conclusions:
epilepsy surgery should be considered in treating childhood intractable EE with expectation of improvement of both seizure and cognitive outcomes, even in cases of LGS.
