[EPILEPSY SURGERY IN CHILDREN: A SUMMARY OF A DECADE AT THE SOURASKY TEL AVIV MEDICAL CENTER].

INTRODUCTION: Drug-resistant epilepsy in children is associated with morbidity, developmental regression and mortality. Over recent years, there is an increase in awareness regarding the role of surgery in the treatment of refractory epilepsy, both in the diagnostic phase and for treatment, reducing the number and magnitude of seizures. Technological advancements have enabled a minimalization of surgery, with reduction in surgical associated morbidity. METHODS: In this retrospective study, we review our experience with cranial surgery for epilepsy between the years 2011-2020. Collected data included information regarding the epileptic disorder, surgery, surgical-related complications and epilepsy outcome. RESULTS: A total of 93 children underwent 110 cranial surgeries over a decade. The main etiologies included cortical dysplasia (29), Rasmussen encephalitis (10), genetic disorders (9), tumors (7) and tuberous sclerosis (7). The main surgeries included lobectomies (32), focal resections (26), hemispherotomies (25), and callosotomies (16). Two children underwent MRI-guided laser interstitial thermal treatment (LITT). The most significant improvements following surgery were following hemispherotomy or tumor resection (100% of children, each). Following resections for cortical dysplasia led to a significant improvement in 70%. In 83% of children undergoing callosotomy, there were no additional drop seizures; 14% of the entire group underwent additional epilepsy surgery; 23% of children had an unexpected complication, in the vast majority with no permanent sequela. There was not mortality. CONCLUSIONS: Epilepsy surgery may lead to significant improvement and even cure of epilepsy. There is a wide span of epilepsy surgical procedures. Ealy referral of children with refractory epilepsy for surgical evaluation may significantly reduce the developmental injury, and improve functional outcomes.
