RATIONALE: Surgical treatmnt is an effevtive method for intractable epilepsy patients, but recurrent epilepsy after the first operation occures with some patients.We are trying to find the reasons that caused the unsatisfactory outcomes, and trying to find some better ways to solve the problems.
METHODS: 27 cases with recurrent epilepsy, 11 cases firstly treated with gamma-knife and X-knife, 2 cases with stereotactic lesion destroyes, 14 cases with crani-octomy and surgical invasive treatments, all patiens had a re-operation based on the first surgical experiences and the pre-reoperation comprehensive evaluation. The epileptogenic foci, having a relationship with the first operation, had been found with EcoG monitoring during the second operation. The re-operations were mainly to eliminata or to resecte the epileptogenic areas, when these areas located in the functional cortexes, the bipolar coagulation technique could be used, the out-put power is 4U, the duration 1-2 s at interval 5mm apart (the bipolar coagulator is made in SWEDEN).
RESULTS: The early effects of the re-operation are well followed by only 3-5monthes, all paients had a lesser seizure attacks than pre-operation, and the later effects are uncertain.
CONCLUSIONS: The surgical treatments for the patients with refractory epilepsy are not only to resect the epileptic foci, but also to eliminate the epileptogenic areas completely.
