[Current status of epilepsy surgery in Spain. Compendium and awareness]

Drug-resistant epilepsy affects between a third and a quarter of patients with epilepsy. Within this group, with a poorer quality of life and high healthcare costs, there is a considerable proportion of patients with potentially surgical causes of epilepsy, and epilepsy surgery is a proven therapeutic option. In Spain, we do not know the actual number of patients who are treated in relation to the total number of cases of refractory epilepsy that could benefit from surgical treatment.

To analyse the number of epilepsy surgical interventions performed and published in relation to the potential cases of refractory epilepsy who are candidates for surgery in our country.

A review was carried out through a literature search in PubMed and Cochrane of articles published between 1990 and 2020, combining the following words and Boolean operators: 'epilepsy surgery IN Spain'. The evidence and recommendations were classified according to the prognostic criteria of the Oxford Centre for Evidence Based Medicine (2001) and of Neurological Societies (2004) for therapeutic actions.

The majority (75.6%) of the publications came from the autonomous communities of Madrid and Catalonia and 46.4% of the articles published were short series. We counted 2,113 surgical interventions (resections, palliative interventions, implantation of deep electrodes and implantation of neurostimulators), which represents 8.7% of the estimated population with refractory epilepsy.

Epilepsy surgery in our country is an underused therapeutic indication that is not offered or administered to the majority of potential beneficiaries.
