ABSTRACT
PURPOSE:
To evaluate the accuracy of expert estimations of achieving seizure freedom after epilepsy surgery in the context of presurgical patient counseling.METHOD:
The retrospective study comprised a random sample of 200 patients who underwent any type of resective epilepsy surgery at the University of Bonn Epilepsy Center and the routine 1-year postoperative control visit in the years from 2008-2016. The prediction by a team of epileptologists and the actual seizure outcome were extracted from the pre- and postsurgical medical files, respectively. A deviation of >10% was a priori defined as a relevant discrepancy.RESULTS:
Estimated chances of achieving seizure freedom ranged from 30 to 90% (mean 67%). The actual seizure freedom rate was 66% (Engel Ia/ ILAE 1a). Nine of 12 estimation categories showed a tolerable deviation of ≤10%, none of these with a worse than expected outcome. Two estimation categories (40-50%, and 80%) showed a worse actual seizure outcome with deviations of -40% (nâ¯=â¯3); and -17% (nâ¯=â¯30), respectively. All in all, for 83% of the patients a correct prediction was provided.CONCLUSIONS:
For the vast majority of surgical patients, the expert prediction of postsurgical seizure freedom at the 1-year follow-up was accurate despite the heterogeneity of patients and surgical procedures.Palavras-chave
