Abstract OBJECTIVE Pediatric epilepsy surgery candidates with unilateral congenital or early-acquired brain lesions may present with refractory seizures and generalized electroencephalographic features such as electrical status epilepticus in sleep (ESES). The purpose of our study was to review the clinical presentation, neuroimaging findings, and outcome in a series of children with unilateral brain lesions and ESES undergoing resective surgery for refractory epilepsy. METHODS A total of 415 consecutive patients younger than 18 years of age undergoing video electroencephalographic evaluation and epilepsy surgery at Cleveland Clinic were reviewed for ESES, an underlying pathological lesion, and outcome after surgery. RESULTS Eight patients were included. All patients presented with medically refractory epilepsy, hemiparesis, and developmental delay. The pathogenesis was perinatal infarction in 7 patients and malformation of cortical development in 1 patient. Preoperative electroencephalography demonstrated generalized interictal spikes, electroencephalographic seizures, and ESES in all cases. Age at the time of surgery ranged from 3 to 14 years. Six patients underwent hemispherectomy, and 2 patients underwent focal resection. Six patients became seizure-free after resection. Two patients with functional hemispherectomy continued to have rare seizures, but were much improved. These patients also had perinatal infarctions in the hemisphere contralateral to the resection, possibly indicating a less beneficial outcome. Postoperative electroencephalography demonstrated resolution of generalized interictal discharges and ESES in all. Formal pre- and postoperative neuropsychological testing showed overall improvement of age-equivalent scores. CONCLUSION Children with unilateral brain lesions and seizures may become seizure-free after epilepsy surgery, even if the preoperative electroencephalogram shows generalized ESES. The lesion occurring early in life and the location of the lesion may play a role in the development of ESES. Cognitive impairment may be aggravated by the persistence of ESES. Preliminary developmental data in this small sample suggest that termination of seizures and possibly of ESES by epilepsy surgery may have developmental benefits.

OBJECTIVERecent trials for temporal lobe epilepsy (TLE) highlight the challenges of investigating surgical outcomes using randomized controlled trials (RCTs). Although several reviews have examined seizure-freedom outcomes from existing data, there is a need for an overall seizure-freedom rate estimated from level I data as investigators consider other methods besides RCTs to study outcomes related to new surgical interventions.METHODSThe authors performed a systematic review and meta-analysis of the 3 RCTs of TLE in adults and report an overall surgical seizure-freedom rate (Engel class I) composed of level I data. An overall seizure-freedom rate was also collected from level II data (prospective cohort studies) for validation. Eligible studies were identified by filtering a published Cochrane meta-analysis of epilepsy surgery for RCTs and prospective studies, and supplemented by searching indexed terms in MEDLINE (January 1, 2012–April 1, 2018). Retrospective studies were excluded to minimize heterogeneity in patient selection and reporting bias. Data extraction was independently reverified and pooled using a fixed-effects model. The primary outcome was overall seizure freedom following surgery. The historical benchmark was applied in a noninferiority study design to compare its power to a single-study cohort.RESULTSThe overall rate of seizure freedom from level I data was 72.4% (55/76 patients, 3 RCTs), which was nearly identical to the overall seizure-freedom rate of 71.7% (1325/1849 patients, 18 studies) from prospective cohorts (z = 0.134, p = 0.89; z-test). Seizure-freedom rates from level I and II studies were consistent over the years of publication (R2< 0.01, p = 0.73). Surgery resulted in markedly improved seizure-free outcomes compared to medical management (RR 10.82, 95% CI 3.93–29.84, p < 0.01; 2 RCTs). Noninferiority study designs in which the historical benchmark was used had significantly higher power at all difference margins compared to using a single cohort alone (p < 0.001, Bonferroni’s multiple comparison test).CONCLUSIONSThe overall rate of seizure freedom for temporal lobe surgery is approximately 70% for medically refractory epilepsy. The small sample size of the RCT cohort underscores the need to move beyond standard RCTs for epilepsy surgery. This historical seizure-freedom rate may serve as a useful benchmark to guide future study designs for new surgical treatments for refractory TLE.

Abstract INTRODUCTION Pediatric refractory epilepsy affects quality of life, clinical disability, and healthcare costs for patients and families. We aimed to show the impact of surgical treatment for pediatric epilepsy on healthcare utilization compared to medically treated pediatric epilepsy over 5 yr. METHODS The Pediatric Health Information System database was used to study hospitalized children with epilepsy using five published algorithms. Refractory epilepsy (RE) patients treated with either antiepileptic medications (AEDs) only or AEDs plus epilepsy surgery (ES) between 1/1/2008 and 12/31/2014 were included. Patients with a history of ES before 1/1/2008 or a vagus nerve stimulation implantation surgery were excluded. ICD-9-CM codes were used to identify ES. Healthcare utilization following the index date at 2- and 5-yr including inpatient, emergency department (ED), and all epilepsy-related visits were evaluated. The propensity scores (PS) method was used to match surgically and medically treated patients. Covariates associated with the probability of receiving surgical treatment were chosen in the logistic regression model for calculating PS. SAS 9.4 and Stata 14.0 were used for data management and statistical analysis. RESULTS A total of 2106 (17.1%) and 10186 (82.9%) were surgically and medically treated, respectively. A total of 4050 matched cases, 2025 per each treated group, were included. Overall survival rates of matched cases were 98.07% and 99.58% at 2-yr and 96.66% and 98.99% at 5-yr for medically and surgically treated patients, respectively. Within 5-yr follow-up, seizure-associated healthcare utilization was lower for the surgically treated group: number of inpatient visits were 3.9 vs 2.5 and ED visits were 3.2 vs 1.7 for medically and surgically treated patients, respectively. The number of AEDs at 1-yr follow-up was significantly lower for the surgically treated group (3.22 decreased to 2.59: surgical group, 3.24 decreased to 3.06: medical group). CONCLUSION We found a significant decrease in inpatient and ED visits and number of antiepileptic drug prescriptions, as well as higher survival rates, at 2- and 5-yr follow-up in the surgically treated group compared to the medically treated group for pediatric patients with refractory epilepsy. Pediatric epilepsy surgery can provide beneficial outcomes, favorable long-term effectiveness, and reduced healthcare utilization compared to medical management.

The Impact

Abstract Objectives: There is a high rate of psychiatric comorbidity in patients with epilepsy. However, the impact of surgical treatment of refractory epilepsy on psychopathology remains under investigation. We aimed to examine the impact of epilepsy surgery on psychopathology and quality of life at 1-year post-surgery in a population of patients with epilepsy refractory to medication. Methods: This study initially assessed 48 patients with refractory epilepsy using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), the Hospital Anxiety and Depression Scale (HADS) and the Quality of Life in Epilepsy Inventory 89 (QOLIE-89) on admission to an Epilepsy Monitoring Unit (EMU) as part of their pre-surgical assessment. These patients were again assessed using the SCID-I, QOLIE-89 and HADS at 1-year follow-up post-surgery. Results: There was a significant reduction in psychopathology, particularly psychosis, following surgery at 1-year follow-up (p < 0.021). There were no new cases of de novo psychosis and surgery was also associated with a significant improvement in the quality of life scores (p < 0.001). Conclusions: This study demonstrates the impact of epilepsy surgery on psychopathology and quality of life in a patient population with refractory surgery. The presence of a psychiatric illness should not be a barrier to access surgical treatment.
