Precision Resection of the Epileptogenic Zone Using Intraoperative Submillimeter Micro-Electrocorticography (Epi-PRECISE): A Single-Arm Trial With an External Historical Control Cohort
What's the clinical value of high-density flexible microelectrocorticography (μECoG) for guiding the resection of epileptogenic zone (EZ) in epilepsy surgery?
Inclusion: Age 3 to 60 years; Diagnosis of drug-resistant epilepsy, defined as persistent seizures despite treatment with two or more appropriately selected, adequately dosed and adequately tried antiseizure medications; Diagnosis of focal epilepsy after standard presurgical evaluation and considered suitable for resective epilepsy surgery; Preoperative cognitive or developmental status sufficient to participate in study assessments, as judged by the investigator and assessed using age-appropriate validated instruments. For participants aged 3 to 6 years, developmental status must be within the normal range according to the Griffiths Mental Development Scales. For participants aged 6 to 16 years, cognitive function must be within the normal range according to the Wechsler Intelligence Scale for Children. For participants older than 16 years, a Mini-Mental State Examination score of 24 or higher will be required; Written informed consent provided by the participant or, when applicable, by a legal guardian.
Exclusion: History of any previous neurosurgical craniotomy before epilepsy surgery; Contraindication to surgery; Suspected mesial temporal lobe epilepsy after multidisciplinary presurgical evaluation; Severe psychiatric, cognitive, or psychological disorder that prevents participation in the study or completion of follow-up.
