Neurosurgery Training in Greece.

OBJECTIVE: The structure and specifics of neurosurgery residency training vary substantially across programs and countries, potentially leading to differences in clinical reasoning, surgical skills, and professionalism. The Greek neurosurgical training system is unique in numerous respects. This manuscript delineates the current state of neurosurgical residency training in Greece and outlines future directions. METHODS: A narrative review was conducted to describe the Greek neurosurgical residency training structure. The perspectives of the authors regarding challenges in training and future directions were synthesized. RESULTS: This manuscript describes the neurosurgery residency curriculum and board certification process, existing training programs, and key challenges in neurosurgery residency training in Greece. The authors propose future directions to reform neurosurgical training in Greece. CONCLUSIONS: Neurosurgery residency training in Greece has been largely unchanged for many years. This review leads to suggested modification of the existing training process may improve the quality of training and equip neurosurgeons to respond to the rapidly changing landscape of the field.

A systematic review on the prevalence of preoperative and postoperative depression in lumbar fusion.

BACKGROUND: Depression and Degenerative Spine Disease (DSD) frequently co-exist. Pooled prevalence estimates of depression before and after lumbar fusion surgery has not been analyzed before. The purpose of this systematic review was to estimate the pre- and post-operative prevalence of depression in patients with DSD undergoing lumbar fusion. METHODS: A literature review until April 30th 2022 was performed. All studies on DSD patients undergoing lumbar spine fusion surgery with either a history of formal diagnosis of depression or a recording of depression using a validated tool were included. Patients with other psychiatric conditions or undergoing a different form of spinal surgery were excluded. Risk of bias of the included studies was evaluated using the Newcastle-Ottawa Scale. RESULTS: Fifteen (15) studies with a total of 98.375 patients met the inclusion and exclusion criteria and were included in the analysis. The prevalence estimate of depression in patients before surgery was 15,35 % (95% CI: 10,56-20,86%). In the 7 studies including patients who had undergone lumbar fusion, the pooled prevalence was estimated 11,46% (95% CI: 8,11-15,30%). CONCLUSION: An increased prevalence of depression in patients undergoing lumbar spine fusion was noted. Given the correlation between depression and poor surgical outcomes, strategies should be identified to prevent and treat depression in these patients.

Clinical outcome following decompression and short or long instrumented fusion in lumbar degenerative spinal stenosis. A prospective case-control analysis.

OBJECTIVES: There is limited data on the direct clinical comparison between short and long fusion following surgery for lumbar spinal stenosis. The hypothesis that regardless their baseline characteristics and morbidity, clinical outcome is similar in patients with lumbar stenosis treated with decompression plus posterior instrumented fusion in one or two versus three to five levels was tested. METHODS: Subjects were divided into Group A and Group B corresponding to stenotic pathology and instrumented fusion in one or two levels and three to five levels, respectively. Primary outcome measures at one year were the change in SF-36 physical component (PCS) and Oswestry Disability Index (ODI). Secondary outcome measures included the EuroQol-5D (EQ-5D), the Visual Analog Scale (VAS), the mental component (MCS) of SF-36 scale and the Zung Self-Rating Depression Scale. RESULTS: Seventy seven (77) patients were included (Group A, n = 42; Group B, n = 35). Patients in Group B were older, surgery lasted longer and intraoperative blood loss was greater than patients in Group A (p < 0.05). A significant clinical improvement was noted in both Groups on all scales (p < 0.01). Clinical outcome at one year was equally favorable in both Groups (p > 0.05). The evaluation of depression for Group A showed a significant improvement at one year (p = 0.02) compared to the preoperative status. CONCLUSIONS: Older individuals are more likely to have multilevel stenosis and more co-morbidities and they were associated with longer instrumentation. However, complications are similar and clinical outcome is equally favorable compared to short instrumented fusion for fewer levels of disease.
