Abstract
To identify variables independently associated with a meaningful improvement in QOL long after surgical treatment of drug-resistant MTLE-HS patients. We prospectively evaluated 72 consecutive MTLE-HS surgically treated patients and analyzed pre and post-surgical variables independently associated with a meaningful improvement in QOL evaluated by the Quality of Life in Epilepsy-31 (QOLIE-31) overall score, and its domain scores determined at follow-up after 36 to 131months (mean 93months) after surgery. The mean overall QOLIE-31 score and its subdomain scores improved significantly after surgery (p<0.01), and 55 patients (76.4%) had a meaningful QOL improvement. Being seizure-free (Engel IA) after surgery showed a non-significant association (OR 2.63, CI 95% 0.53 to 13.05, p=0.23) and lower depressive symptoms a significant association (OR 4.15, CI 95% 1.19 to 14.53, p=0.03) with meaningful improvement of QOL. Patients with MTLE-HS who underwent epilepsy surgery show a sustained, meaningful improvement in their QOL. Pre-surgical variables do not predict long-term QOL improvement after surgery. Lower levels of depressive symptoms at postoperative evaluation are associated with meaningful QOL improvement.
