Objective To present a surgical series of patients with low grade temporal gliomas causing intractable epilepsy, focusing on long-term seizure outcome.Method A retrospective study was conducted with patients with temporal low-grade gliomas (LGG).Results Sixty five patients with were operated in our institution. Males were more affected than females and the mean age at surgery was 32.3 ± 8.4 (9-68 years). The mean age at seizure onset was 25.7 ± 9.2 (11-66 years). Seizure outcome was classified according with Engel classification. After one year of follow up, forty two patients (64.6%) were Engel I; seventeen (26.2%) Engel II; four (6.2%) Engel III and two (3.1%) Engel IV. Statistically significant difference in seizure outcome was obtained when comparing the extension of resection. Engel I was observed in 39 patients (69.6%) with total resection and in only 3 (33.3%) patients with partial resection.Conclusion Gross-total resection of temporal LGGs is a critically important factor in achieving seizure-freedom.
Objective To investigate the surgical outcomes of temporal lobe epilepsy associated with hippocampal sclerosis (TLE-HS) and neurocysticercosis (NCC). Methods A retrospective investigation of patients with TLE-HS was conducted in a tertiary center. Results Seventy-nine (62.2%), 37 (29.1%), 6 (4.7%), and 5 (3.9%) patients were Engel class I, II, III, and IV, respectively. Fifty-two (71.2%) patients with epilepsy durations ≤ 10 years prior to surgery were seizure-free 1 year after the operation compared to 27 (50.0%) patients with epilepsy durations > 10 years (p = 0.0121). Forty-three (72.9%) patients with three or fewer lobes affected by NCC were seizure-free one year after the operation, and 36 (52.9%) patients with more than three involved lobes were seizure-free after surgery (p = 0.0163). Conclusions Longer epilepsy durations and multiple lobe involvement predicted worse seizure outcomes in TLE-HS plus NCC patients.
Introduction Refractory epilepsy is a debilitating and challenging condition to manage. Corpus callosotomy (CC) seems to be an effective treatment option for patients with seizures not amenable to focal resection. The aim of the present study is to compare seizure outcome of pediatric patients following anterior CC, compared with complete CC. Method The authors performed a systematic review and meta-analysis of the English literature involving comparative studies. Results The present investigation includes four retrospective case-controlled studies and authors perform a pooled analysis of the surgical results. Seizure outcome presented favorable results in patients who underwent complete CC (Odds Ratio, M-H, Fixed, 95% CI: 3.02 [1. 43,6.387], p-value: 0.005). Clinical and neurological complications occurred independently when a complete or anterior CC was performed. Conclusion Complete CC seems to be the most effective treatment option to control intractable seizure in children not amenable to focal resection.
In order to identify the most appropriate candidates for ATL, it is very important to consider the prognostic factors associated with a favorable outcome for counseling patients in daily practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
