ABSTRACT
BACKGROUND: Temporal lobe epilepsy (TLE) is a high prevalence neurological disorder. Surgery has emerged as a promising treatment. OBJECTIVE: The objective of this work is to compare the surgical results of anterior temporal lobectomy (ATL) versus selective amygdalohippocampectomy (SAH) in a cohort of 132 patients. METHODS: We performed a retrospective study of 146 patients operated for TLE from 2008 to 2019. Initially, 13 patients were excluded from the study due to insufficient medical record data or follow-up loss. One patient was excluded from the analysis of the results due to death in the first postoperative week. We used the ILAE scale to classify seizure control after surgery. In patients with left hippocampal sclerosis, SAH was performed and in right temporal lobe epilepsy, ATL was the approach of choice. RESULTS: The mean follow-up time after surgery was 57.2 months (12-137). In our data analysis, we found that the group of patients undergoing ATL had a higher prevalence of being completely seizure-free (ILAE I) (57.1% versus 31%) and a higher rate of satisfactory seizure control (88.6% versus 69.3%) p = 0,006, when compared with patients undergoing SAH. CONCLUSION: The literature is still controversial about seizure control concerning the technique used due to the lack of a robust methodology. Our data analysis identified the superiority of ATL over SAH in seizure outcomes. ATL may be the best option for adequately controlling seizures with minimal additional morbidity in countries with a cost limitation for extended propaedeutics.
ANTECEDENTES: A epilepsia do lobo temporal (TLE) é uma desordem neurológica de alta prevalência. A cirurgia surgiu como um tratamento promissor. OBJETIVO: O objetivo deste trabalho é comparar os resultados da lobectomia temporal anterior (ATL) versus amigdalohipocampectomia seletiva (SAH) em uma coorte de 132 pacientes. MéTODOS: Realizamos um estudo retrospectivo de 146 pacientes operados por TLE de 2008 a 2019. Inicialmente, 13 pacientes foram excluídos por insuficiência de dados em prontuário ou perda de seguimento. Um paciente foi excluído da análise por óbito na primeira semana de pós-operatório. Usamos a escala ILAE para classificar o controle das crises após a cirurgia. Em pacientes com esclerose hipocampal à esquerda, foi realizada a SAH, e na epilepsia do lobo temporal à direita, a ATL foi a abordagem de escolha. RESULTADOS: O tempo médio de seguimento após a cirurgia foi de 57,2 meses (12137). Em nossa avaliação, encontramos que o grupo de pacientes submetidos à ATL apresentou maior prevalência de ausência total de crises (ILAE I) (57,1% versus 31%) e maior taxa de controle satisfatório da epilepsia (88,6% versus 69,3%) p = 0,006, quando comparado ao grupo submetido à SAH. CONCLUSãO: A literatura ainda é controversa em relação à redução das crises de acordo com a técnica utilizada devido a falta de uma metodologia robusta. Nosso estudo identificou superioridade da ATL sobre a SAH nos desfechos convulsivos. ATL pode ser a melhor opção para controlar adequadamente as convulsões com morbidade adicional mínima em países com limitação de custo para propedêutica estendida.

ABSTRACT
BACKGROUND: Sodium fluorescein (SF) is currently considered a valid intraoperative adjunct in the resection of high-grade brain lesions in adults. Experiences in pediatric groups and in low-grade gliomas and other low-grade lesions are still limited in literature, and subjective evaluation of fluorescence is still a limitation. MATERIAL AND METHODS: This study retrospectively reviewed all patients with brain or spine lesions operated on from September 2021 to July 2022 in the Pediatric Neurosurgery Unit of Hôpital Femme Mère Enfant, Lyon, who had received 5 mg/kg of 10%. Surgery was performed using a YELLOW560 filter at crucial times. At the end of surgery, the first operator completed a questionnaire, including his opinion on whether SF had been useful in tumor resection, recorded as a binary variable. Post hoc, surgical images were reviewed using ImageJ, an open-source Java image processing platform. In order to compare independent discrete variables, we applied the Student's t test, and we applied the Chi-square or Fisher exact test for binary variables. A threshold of p < 0.05 was set for statistical significance. RESULTS: We included 50 pediatric patients (0.2-17.6 years old). Forty/50 lesions showed SF uptake (80%). The differentiation between healthy and affected tissue, thanks to SF, subjectively evaluated by the surgeon, had as objective counterpart the statistically significant higher brightness of green in lesions, registered by the software (p < 0.001). SF overall allowed a good differentiation in 33/50 lesions, and overall utility of SF has been noted in 67% of them. When specifically considering gliomas, overall utility reached 75%. CONCLUSION: SF is a feasible, safe, and useful intraoperative adjunct in pediatric neurosurgery. In particular, it seems to have a promising role in some low-grade infiltrating glial tumors. The subjective evaluation of fluorescence seems to be reliable with respect to image analyses software.
