Refractory epilepsy represents between 17-25% of all epilepsies in different series. Surgical management has become a useful treatment in some selected cases. This trial describes the surgical management and outcome of patients with a refractory epilepsy and atonic seizures treated with callosotomy. Patients and methods: it is a revision trial of a group of patients with refractory atonic epilepsy and a clinical correlation before and after callosotomy up today. The data were obtained in retrospective by charts and demographic variables were analyzed, it showed a good outcome according to Engel's Scale. Results: the total of patient's management with callosotomy between march 1998 and november 2002 were five. The indication for surgery was: refractory atonic seizures. We report a good outcome in all patients according to Engel's Scale, with no statistical significance, (Spearman of R = 0.57 with a p = 0.30) (Wilcoxon p = 0.06). We found less medication consumption after surgery (Wilcoxon p =0.043). Discussion: considering the number of patients with refractory epilepsy, it is necessary to apply an epilepsy surgical protocol that is developing in our hospital. Conclusion: the callosotomy has shown to be a safe and useful surgical procedure in the management of patients with refractory epilepsy of atonic type as is showed in the present trial.
