title: AES 2009 Annual Course: Reoperation for medically refractory epilepsy.
abstract: A significant percentage of patients undergoing resective surgery for medically refractory epilepsy have persistent or recurrent disabling seizures. In these patients, the objective of seizure freedom justifies the consideration of repeat resective surgery. In this report, the available published experience with repeat resective surgery is analyzed. The reoperated patients are subdivided into three categories: patients with residual medial temporal structures, patients with an unresected or partially resected structural/mass (non-glioma) lesion and patients with non-lesional neocortical epilepsy. This analysis indicates that the chance of achieving seizure freedom is significant, although lower than with the initial surgery. The chance of significant morbidity (particularly significant neurologic deficit) is low, although higher than with the initial surgery. A proper evaluation can identify appropriate candidates for a resective reoperation. Palliative surgical options should be strongly considered for all patients, especially for those with lower chance of seizure freedom and/or elevated risk of morbidity.
