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

Introduction: 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.

Safety and effectiveness of surgery for epilepsy in children. Experience of a tertiary hospital in Ecuador.

Introduction: There is sufficient evidence on the usefulness of surgery as a therapeutic alternative for patients with drug-resistant epilepsy; however this treatment is underutilized, especially in developing countries.

Methods: We describe the outcomes of epilepsy surgery in 27 paediatric patients at Hospital Baca Ortiz in Quito, Ecuador. Our analysis considered the following variables: reduction in seizure frequency, surgery outcome according to the Engel classification, improvement in quality of life, and serious complications due to surgery.

[Neuronavigation in the surgical planning of callosotomy].

Objective: To describe the usefulness of 3D computer-assisted preoperative neuronavigation for stereoscopic location of the venous sinuses, arterial branches, and corpus callosum, to extrapolate anatomical landmarks on the surgical field and make decisions before the intervention.

Methods: A prospective analysis was performed on patients with refractory epilepsy who underwent neuronavigation-assisted callosotomy (BRAIN LAB Dual).

Results: A total of 10 neuronavigation-assisted callosotomies were performed in the year 2014.
