Purpose: Resective epilepsy surgery in early childhood has become an important treatment option for selected infants and children with epilepsy. We describe experience and clinical outcomes of children under 3 years undergoing epilepsy surgery at Great Ormond Street Hospital (GOSH). Methods: All children under 36 months of age who had resective surgery for the purpose of treating epilepsy within the GOSH epilepsy surgery programme were ascertained using a departmental database. Aetiology, post-operative seizure frequency, pre and post-operative cognitive function, long-term complications and re-operation rates were analysed by retrospective examination of clinical records. Results: Forty-two children were included in our cohort with a median age at surgery of 20 months (range 3-36 months). Surgical procedures comprised 25 functional hemispherectomies, two anatomical hemispherectomies, four multilobar resections, seven lobar resections and four focal resections. 7/42 (17%, 95% CI 8-31%) children underwent re-operation. 20/42 (48%, 95% CI 33-62%) children achieved seizure freedom. 18/42 (43%, 95% CI 29-58) demonstrated an improvement in seizure frequency and no children had an increase in seizure frequency. Post-operative complications included subsequent shunt procedure in 5/25 (20%, 95% CI 9-39%) children undergoing hemispherectomy. There were no mortalities. In 23 children pre- and post-operative DQ or IQ was determinable allowing longitudinal comparison. Five children had a decrease in DQ/IQ >15 and two children had an increase DQ/IQ >15. Discussion: Epilepsy surgery in children under 3 years of age offers suitable candidates a good chance of significantly improved seizure outcome which compares with rates in older cohorts.
