Study Overview
Brief Summary
The goal of the real-world study is to evaluate the long-term seizure control outcomes, postoperative complications, long term impact on cognitive, memory function outcomes, quality-of-life measures, and healthcare resource utilization of magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) on patients with drug-resistant epilepsy (DRE).
Detailed Description
Epilepsy, a complex neurological disorder characterized by recurrent seizures, affects millions of individuals worldwide, challenging both patients and healthcare providers. The main indication for the epilepsy surgery is the drug resistance as per the consensus from the Task Force of the International League Against Epilepsy (ILAE). Traditional open surgery is an established treatment for drug-resistant epilepsy (DRE), but has limitations such as invasiveness and long recovery times. With the significant advancements of technology, the minimally invasive therapeutic approaches have emerged, among which Magnetic Resonance-guided Laser Interstitial Thermal Therapy (MRgLITT) stands out as a promising intervention. It provides targeted ablation of epileptogenic tissue while preserving healthy brain regions. Understanding MRgLITT's comprehensive value for DRE is of increasing interest.
This real-world study aims to comprehensively evaluate the clinical outcomes, safety profiles, and cost-effectiveness of MRgLITT in patients with DRE. The results of this clinical trial protocol are expected to serve as a comprehensive guide for researchers, clinicians, and stakeholders interested in the treatment of DRE using MRgLITT. We believe this study can influence future treatment strategies, leading to improved outcomes and enhanced quality of life for individuals with epilepsy.
