“…Advancements in the diagnosis and treatment of hydrocephalus have rapidly improved over the last century [ 12 ]. From the first attempt to create a permanent ventriculo-subarachnoid-subgaleal CSF diversion by Mikulicz in 1893, to the first functional valve implantation devised by Nulsen and Spitz in 1949, the basis of treatment for hydrocephalus has largely remained the same [ 13 , 14 ].…”

Introduction Hydrocephalus is a significant public health concern estimated to affect 380,000 new individuals annually. In addition, it exhibits an increasingly high financial burden for the healthcare industry. Clinical trials are the gold standard for evaluating preventative and therapeutic strategies to bring potential treatments to the forefront of clinical practice. Methods A study of the ClinicalTrials.gov was conducted in April 2019 to examine all current and previously reported clinical trials studying hydrocephalus. Studies were reviewed to extrapolate information to characterize the current state of research being conducted for hydrocephalus. Results In total, 80 clinical trials met inclusion criteria and were analyzed: 48.8% were observation and 51.2% were interventional. Of those, 55% have been completed while 30.0% are still recruiting, and 15.0% are not yet recruiting. The United States has the most clinical trials (42.0%) and a plurality of trials has a sample size of 0-50 participants. The majority of studies included only adults (53.8%). Of those studies, 54.0% were cohort and the majority were prospective (74.0%). Of the different types of hydrocephalus, normal pressure hydrocephalus and pediatric hydrocephalus have generated the most interest for research comprising a majority of the clinical trial registry. While 44 of the trials are complete, only 20 have published results in peer-reviewed literature highlighting the need for improvement in publishing study results even if the results of the trials are null. Conclusion Most clinical trials to date have pertained to the treatment of normal pressure hydrocephalus and pediatric hydrocephalus. While great advancements have been made for the treatment of hydrocephalus, there remains much room for improvements in therapeutic interventional modalities as well as ensuring the reporting of all undertaken clinical trials.

“…[1] It has been adapted due to the anatomic requirements and due to the specific preferences of the surgeon. [3,4] The innovative microinspection tool which was the subject of our investigation can be seen as a further improved endoscope which offers advantages in the visualization and handling.…”

“…[1,3] Endoscopes are increasingly used for transnasal approaches to the sphenoid sinus and the sellar region, and endoscopes with working channels are almost exclusively employed in third,ventriculostomy. [4,5] The use of an endoscope is often elaborate, expensive, and time-consuming, and only few neurosurgeons are trained in full endoscopic surgery.…”

Background: The use of endoscopes in neurosurgery is well established, but the integration of a full high definition signaling, 45° angled endoscopic tool into a digital surgical microscope, is new. We report our first experiences in a cadaveric study and a clinical case series using the new microinspection tool QEVO® that serves as a plug-in feature for the recently launched KINEVO 900 digital visualization platform (CARL ZEISS MEDITEC, Oberkochen, Germany). For illustration purposes, we offer video footage. Methods: The handling, workflow, and visualization patterns of the QEVO® microinspection tool were critically evaluated in cadaver specimens by simulating four standardized neurosurgical approaches: (1) pterional, (2) retrosigmoidal, (3) transsphenoidal, (4) and transcallosal. Similarly, we evaluated the QEVO® tool in corresponding clinical cases of (1) aneurysm clipping, (2) removal of cerebellar cavernoma, (3) and pituitary adenomectomy. Results: In both the cadaveric study and clinical case series, the QEVO® tool was found to be beneficial in terms of high-quality visualization of fine structures and for displaying hidden anatomical details (“looking around the corner”). The handling was good, and the workflow was easy. However, the use of this tool was restricted by the lack of an external fixation and a working channel, the shortness of the tool, and the impossibility to switch to a 0° or 30° optic. Conclusion: Despite some restrictions, the QEVO® microinspection tool is an innovative, handheld, endoscopic tool that allows excellent additional visualization of the surgical field. In our opinion, this tool effectively enhances the modern neurosurgical armamentarium.

With the evolution of surgical techniques, endoscopy has emerged as a suitable alternative to many instances of more invasive methods. In this review article, we aim to discuss the endoscopic advancements, procedural details, indications, and outcomes of the most commonly practiced neuroendoscopic procedures. We have also summarized the uses, techniques, and challenges of neuroendoscopy in select neurosurgical pathologies.
