Impact of hemispherotomy on quality of life and burden of caregivers in children and adolescents: a retrospective observational study.

Abstract Purpose: To evaluate QOL and caregiver burden of children and teenagers submitted to hemispherotomy for pharmacoresistant epilepsy, by comparing pre and post surgical intervention data. Materials and methods: Retrospective analysis of pediatric patients submitted to surgical hemispherotomy before intervention (preOP) and their follow-up at 6 months (6M PO) and 2 years (2Y PO) after surgery. QOL was evaluated through the Quality of Life in Childhood Epilepsy (QVCE-50) questionnaire and caregiver burden, through the Zarit Burden Interview (ZBI) tool. Results: Twenty-two patients were included in the study. Sixteen patients (72%) were classified as Engel I at 2Y PO follow-up. QVCE-50 scale showed improvement of total QOL at 2Y PO. In relation to QVCE-50 specific domains, there was an improvement in the physical domain and in the cognitive-education; a decrease in psychological and a stabilization in social/familiar domain scores. The majority of caregivers classified their burden as mild to moderate, with no PO improvement. Conclusions: Hemispherotomy represents an effective seizure control treatment, as well as it contributes to improvement of QOL, particularly in the physical domain and in spite of children's physical and cognitive limitations. However, no improvement in caregiver burden was observed, probably due to the chronic condition of these patients, which might be worsened by social issues.
