Chirurgiczne leczenie epilepsji u dzieci: globalne badanie dotyczące kierowania pacjentów i praktyk przygotowania do zabiegu
Pediatric epilepsy surgery: Global survey of referral and presurgical evaluation practices
W skrócie
Badanie obejmowało 2427 dzieci z całego świata, które przeszły zabiegi chirurgiczne na mózgu z powodu epilepsji. Średni wiek pacjentów to około 9 lat, a epilepsja trwała u nich średnio ponad 5 lat przed operacją. Badacze stwierdzili, że różne regiony świata stosują różne metody przygotowania pacjenta do zabiegu - na przykład w Stanach Zjednoczonych częściej wykonuje się zaawansowane badania obrazowania mózgu, a w niektórych rejonach wcześniej wykonuje się powtórne operacje.

OBJECTIVE: Pediatric epilepsy surgery is well established, but contemporary global data on referral and presurgical evaluation practices are lacking. This International League Against Epilepsy (ILAE) Pediatric Epilepsy Surgery Task Force study provides an updated overview of current trends and regional differences. METHODS: Group-level data were collected from 61 epilepsy surgery programs (49 pediatric-only) across 29 countries and six continents, identified through ILAE networks, and included all children and adolescents treated in 2023 who underwent presurgical evaluation/epilepsy surgery. RESULTS: Group-level data were available for 2427 patients. Mean age at surgery was 9.1 ± 4.9 years; mean epilepsy duration was 5.3. At surgery, 3.2% were <1 year old (highest in Oceania: 5.1%), and 6.1% were nonpharmacoresistant (highest in Europe: 15.0%). Prior neurosurgery was reported in 14.2% (highest in North America: 28.8%), including 8.0% resections (6.1% for epilepsy, 1.5% for tumors; highest in Oceania: 16.5%), 2.3% disconnections (1.3% corpus callosotomy; highest in South America: 4.7%), and 4.2% neuromodulation (3.7% vagal nerve stimulation, .2% responsive neurostimulation, one deep brain stimulation; highest in North America: 12.2%). Developmental and epileptic encephalopathies (DEEs) at surgery included Lennox-Gastaut syndrome (7.4%), infantile epileptic spasms syndrome (5.1%), and DEE with spike-wave activation in sleep (1.5%). Presurgical investigations included fluorodeoxyglucose positron emission tomography (52.6%; highest in Oceania: 79.7%), genetic testing (46.8%; highest in Asia: 54.3%), magnetic resonance imaging (MRI) postprocessing (32.4%; highest in South America: 53.0%), functional MRI (fMRI; 15.2%; highest in North America: 40.3%), magnetoencephalography (11.9%; highest in North America: 39.3%), single photon emission computed tomography (9.6%; highest in North America: 22.2%), high-density electroencephalography (EEG; 1.9%; highest in Europe: 4.7%), source localization (1.6%; highest in Oceania: 7.6%), Wada test (1.2%; highest in North America: 3.5%), and EEG-fMRI (.5%; highest in Europe: 1.1%). SIGNIFICANCE: Despite some early surgeries, including in infancy and before pharmacoresistance, mean epilepsy duration before surgery remains >5 years. Reoperations are common, with resection more frequent than neuromodulation. Genetic testing in nearly half of patients reflects its growing relevance, and the high rate of DEEs underscores the complexity of surgical candidates.
