Burnout in Neurosurgery.

BACKGROUND: Burnout is a pervasive psychosocial syndrome that manifests as a chronic response to interpersonal stressors encountered in the occupational setting. Neurosurgeons exhibit a high prevalence rate of burnout, ranging from 33% to 67%. The primary objective of this study is to examine the prevalence of Burnout syndrome within the neurosurgical community and identify the contributing factors. METHODS: A prospective observational study was conducted utilizing an anonymous survey format, incorporating the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) questionnaire. Additional inquiries were made regarding demographic characteristics, occupational factors, lifestyle choices, and the Hospital Anxiety and Depression Scale (HADS) questionnaire. The survey was disseminated between March 23rd, 2023, and April 4th, 2023, utilizing the email registries of the Spanish Society of Neurosurgery (SENEC) and the Latin American Federation of Neurosurgical Societies (FLANC). Descriptive analysis was performed, comparing responses between participants with and without burnout syndrome using cross-tabulation and the Chi-square test to assess the presence of dependency. RESULTS: A total of 282 neurosurgeons completed the survey. The sample comprised 30.1% females and 69.9% males, with a median age within the 30-40 range. Among the surveyed neurosurgeons, 66.7% exhibited a prevalence of burnout, while 23.4% met the criteria for defined burnout. Significantly higher rates of burnout syndrome were observed among residents, specifically those in their fifth year of residency, as well as those whose departments perform a moderate range of surgeries (500-1000), participating in on-call duties, lacking regular physical exercise (at least twice a week), engaging infrequently in social activities with friends, lacking extracurricular hobbies, and obtaining scores exceeding 10 points in any of the HADS subscales. CONCLUSIONS: Burnout syndrome affects nearly a quarter of the neurosurgical specialists included in this study. Moreover, a distinct profile associated with defined burnout among neurosurgeons emerges, encompassing characteristics such as being a fifth-year resident, belongs to departments with a moderate number of surgeries, with few extra-occupational distractions and exhibiting symptoms of depression or anxiety.

The Integration of 3D Virtual Reality and 3D Printing Technology as Innovative Approaches to Preoperative Planning in Neuro-Oncology.

Our study explores the integration of three-dimensional (3D) virtual reality (VR) and 3D printing in neurosurgical preoperative planning. Traditionally, surgeons relied on two-dimensional (2D) imaging for complex neuroanatomy analyses, requiring significant mental visualization. Fortunately, nowadays advanced technology enables the creation of detailed 3D models from patient scans, utilizing different software. Afterwards, these models can be experienced through VR systems, offering comprehensive preoperative rehearsal opportunities. Additionally, 3D models can be 3D printed for hands-on training, therefore enhancing surgical preparedness. This technological integration transforms the paradigm of neurosurgical planning, ensuring safer procedures.

Development and evaluation of a 3d printed training model for endoscopic third ventriculostomy in low-income countries.

Introduction: Pediatric hydrocephalus is highly prevalent and therefore a major neurosurgical problem in Africa. In addition to ventriculoperitoneal shunts, which have high cost and potential complications, endoscopic third ventriculostomy is becoming an increasingly popular technique especially in this part of the world. However, performing this procedure requires trained neurosurgeons with an optimal learning curve. For this reason, we have developed a 3D printed training model of hydrocephalus so that neurosurgeons without previous experience with endoscopic techniques can acquire these skills, especially in low-income countries, where specific techniques training as this, are relatively absent. Research Question: Our research question was about the possibility to develop and produce a low-cost endoscopic training model and to evaluate the usefulness and the skills acquired after training with it. Material and Methods: A neuroendoscopy simulation model was developed. A sample of last year medical students and junior neurosurgery residents without prior experience in neuroendoscopy were involved in the study. The model was evaluated by measuring several parameters, as procedure time, number of fenestration attempts, diameter of the fenestration, and number of contacts with critical structures. Results: An improvement of the average score on the ETV-Training-Scale was noticed between the first and last attempt (11.6, compared to 27.5 points; p<0.0001). A statistically significant improvement in all parameters, was observed. Discussion and Conclusion: This 3D printed simulator facilitates acquiring surgical skills with the neuroendoscope to treat hydrocephalus by performing an endoscopic third ventriculostomy. Furthermore, it has been shown to be useful to understand the intraventricular anatomical relationships.

[Volumetric measurement of the posterior fossa and its components using magnetic resonance imaging in idiopathic trigeminal neuralgia]. / Estudio volumetrico por resonancia magnetica de la fosa posterior y sus componentes en la neuralgia del trigemino idiopatica.

INTRODUCTION: The neurovascular conflict is now considered an unquestionable dogma in the pathophysiology of idiopathic trigeminal neuralgia (ITN). However, there are more and more papers that provide information about other factors that promote such conflict or neuralgia itself. AIMS. To measure the volume of the substructures of the posterior fossa in patients with ITN and controls and to investigate the association between a reduced volume of these structures and the incidence of ITN. SUBJECTS AND METHODS: In 20 patients with unilateral ITN and 20 healthy participants, high resolution 1.5 T magnetic resonance imaging scans including axial and coronal sequences T2-weighted with a slice thickness of 1 mm were performed with the aim of a volumetric study of pontomesencephalic cistern, Meckel's cave and trigeminal nerve. RESULTS: Measuring the pontomesencephalic cistern on each side of the midline, the volume of the affected side cistern was significantly lower than the healthy side one in patients with ITN (p = 0.004) and also when compared with controls hemicisterns. No significant differences in the Meckel's cave nor the trigeminal nerve were found. The incidence of neurovascular conflict was also studied resulting in 10% of patients with ITN where the conflict was not identified. CONCLUSIONS: Our data support the theory that a small volume of the posterior fossa cisterns containing the trigeminal nerve may increase the incidence of ITN.
