Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Epilepsy Treatment

Background:

  • Endoscopic epilepsy surgery is an emerging minimally invasive alternative to traditional open surgery.
  • This approach aims to reduce bone and brain resection, thereby lowering surgical morbidity.
  • It represents a significant advancement in the surgical management of epilepsy.

Purpose of the Study:

  • To systematically review and meta-analyze the favorable outcomes of seizure improvement in patients undergoing endoscopic epilepsy surgery.
  • To evaluate the efficacy of this minimally invasive technique compared to open surgery.
  • To identify patient populations that benefit most from endoscopic epilepsy surgery.

Main Methods:

  • A systematic literature search was conducted on PubMed and Web of Science until January 2023.
  • Two independent researchers extracted data on clinical profiles and outcomes from eligible studies.
  • Fifteen studies involving 340 patients (293 undergoing endoscopic surgery) were included in the review and meta-analysis.

Main Results:

  • A pooled seizure freedom rate of 58% was observed following endoscopic epilepsy surgery.
  • Pediatric populations showed higher positive outcomes (73.27%) compared to mixed-age groups (48%).
  • Patients with hypothalamic hamartomas (HH) demonstrated a favorable outcome proportion of 61.71%.

Conclusions:

  • Endoscopic epilepsy surgery is effective, especially in pediatric patients and those with hypothalamic hamartomas.
  • Patient demographics and disease characteristics are crucial for clinical decision-making.
  • Further prospective trials are needed to establish class I evidence comparing endoscopic to open surgical techniques.
