Contrary to conventional wisdom, the epilepsy surgery rate among adults in North America has remained stagnant according to a recent analysis of data from the Centers for Medicare and Medicaid Services Part B National Summary Data File and the American College of Surgeons National Surgical Quality Improvement Program. A review of 6200 surgeries performed from 2000 to 2013 revealed that temporal lobectomy, the most common operation, was done in 59% of patients, but surgical rates for temporal and extra-temporal surgery did not change significantly during the study period. The researchers concluded that the findings in this study contrasted with previously published reports that suggested a dramatic decline in temporal lobectomy rates at high volume epilepsy centers in recent years. However, investigators did find that surgical adverse effects were higher when statistics from low and high volume centers were combined.
