- Presurgical evaluation and surgery in the pediatric age group are unique in challenges related to caring for the very young, range of etiologies, choice of appropriate investigations, and surgical procedures. Accepted standards that define the criteria for levels of presurgical evaluation and epilepsy surgery care do not exist. Through a modified Delphi process involving 61 centers with experience in pediatric epilepsy surgery across 20 countries, including low-middle- to high-income countries, we established consensus for two levels of care. Levels were based on age, etiology, complexity of presurgical evaluation, and surgical procedure. Competencies were assigned to the levels of care relating to personnel, technology, and facilities. Criteria were established when consensus was reached (>= 75% agreement). Level 1 care consists of children age 9 years and older, with discrete lesions including hippocampal sclerosis, undergoing lobectomy or lesionectomy, preferably on the cerebral convexity and not close to eloquent cortex, by a team including a pediatric epileptologist, pediatric neurosurgeon, and pediatric neuroradiologist with access to video-electroencephalography and 1.5-T magnetic resonance imaging (MRI). Level 2 care, also encompassing Level 1 care, occurs across the age span and range of etiologies (including tuberous sclerosis complex, Sturge-Weber syndrome, hypothalamic hamartoma) associated with MRI lesions that may be ill-defined, multilobar, hemispheric, or multifocal, and includes children with normal MRI or foci in/abutting eloquent cortex. Available Level 2 technologies includes 3-T MRI, other advanced magnetic resonance technology including functional MRI and diffusion tensor imaging (tractography), positron emission tomography and/or single photon emission computed tomography, source localization with electroencephalography or magnetoencephalography, and the ability to perform intra- or extraoperative invasive monitoring and functional mapping, by a large multidisciplinary team with pediatric expertise in epilepsy, neurophysiology, neuroradiology, epilepsy neurosurgery, neuropsychology, anesthesia, neurocritical care, psychiatry, and nursing. Levels of care will improve safety and outcomes for pediatric epilepsy surgery and provide standards for personnel and technology to achieve these levels.

- This article emphasizes the role of the technological progress in changing the landscape of epilepsy surgery and provides a critical appraisal of robotic applications, laser interstitial thermal therapy, intraoperative imaging, wireless recording, new neuromodulation techniques, and high-intensity focused ultrasound. Specifically, (a) it relativizes the current hype in using robots for stereo-electroencephalography (SEEG) to increase the accuracy of depth electrode placement and save operating time; (b) discusses the drawback of laser interstitial thermal therapy (LITT) when it comes to the need for adequate histopathologic specimen and the fact that the concept of stereotactic disconnection is not new; (c) addresses the ratio between the benefits and expenditure of using intraoperative magnetic resonance imaging (MRI), that is, the high technical and personnel expertise needed that might restrict its use to centers with a high case load, including those unrelated to epilepsy; (d) soberly reviews the advantages, disadvantages, and future potentials of neuromodulation techniques with special emphasis on the differences between closed and open-loop systems; and (e) provides a critical outlook on the clinical implications of focused ultrasound, wireless recording, and multipurpose electrodes that are already on the horizon. This outlook shows that although current ultrasonic systems do have some limitations in delivering the acoustic energy, further advance of this technique may lead to novel treatment paradigms. Furthermore, it highlights that new data streams from multipurpose electrodes and wireless transmission of intracranial recordings will become available soon once some critical developments will be achieved such as electrode fidelity, data processing and storage, heat conduction as well as rechargeable technology. A better understanding of modern epilepsy surgery will help to demystify epilepsy surgery for the patients and the treating physicians and thereby reduce the surgical treatment gap.

- Surgical techniques may vary extensively between centers. We report on a web-based survey aimed at evaluating the current technical approaches in different centers around the world performing epilepsy surgery in children. The intention of the survey was to establish technical standards. A request was made to 88 centers to complete a web-based survey comprising 51 questions. There were 14 questions related to general issues, 13 questions investigating the different technical aspects for children undergoing epilepsy surgery, and 24 questions investigating surgical strategies in pediatric epilepsy surgery. Fifty-two centers covering a wide geographic representation completed the questionnaire. The median number of resective procedures per center per year was 47. Some important technical practices appeared (>80% of the responses) such as the use of prophylactic antibiotics (98%), the use of high-speed drills for bone opening (88%), nonresorbable material for bone flap closure (85%), head fixation (90%), use of the surgical microscope (100%), and of free bone flaps. Other questions, such as the use of drains, electrocorticography (ECoG) and preoperative withdrawal of valproate, led to mixed, inconclusive results. Complications were noted in 3.8% of the patients submitted to cortical resection, 9.9% hemispheric surgery, 5% callosotomy, 1.8% depth electrode implantation, 5.9% subdural grids implantation, 11.9% hypothalamic hamartoma resection, 0.9% vagus nerve stimulation (VNS), and 0.5% deep brain stimulation. There were no major differences across regions or countries in any of the subitems above. The present data offer the first overview of the technical aspects of pediatric epilepsy surgery worldwide. Surprisingly, there seem to be more similarities than differences. That aside many of the evaluated issues should be examined by adequately designed multicenter randomized controlled trials (RCTs). Further knowledge on these technical issues might lead to increased standardization and lower costs in the future, as well as definitive practice guidelines.

Tidskriftsartikel (refereegranskat)abstract
- This supplement includes the proceedings from the Pediatric Epilepsy Surgery Techniques Meeting held in Gothenburg (July 4–5, 2014), which focused on presentations and discussions regarding specific surgical technical issues in pediatric epilepsy surgery. Pediatric epilepsy neurosurgeons from all over the world were present and active in very fruitful and live presentations and discussions. These articles represent a synopsis of the areas and subjects dealt with there. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy
