“…Even though our ndings point toward ETV as a good alternative to VPS for OH, even in young children, the number of patients is insu cient to make rm conclusions. However, due to high revision rate for shunt hardware, ETV has also been advocated as a feasible or even superior treatment method in low-and middle-income countries [47,48].…”

Purpose The aim of this study was to provide granular descriptions of aetiologies of hydrocephalus and concurrent conditions. Furthermore, to describe the short-term effect of ventriculoperitoneal shunt (VPS) and endoscopic third ventriculostomy (ETV) on preoperative symptoms and to estimate the risks of shunt revision, conversion of ETV to shunt, and the risks of complications. Methods A retrospective, single-centre study was performed among children who underwent shunt insertion or ETV for hydrocephalus between December 1st, 2016 and December 31st, 2021. Information regarding course of disease, surgical treatments, and comorbidities were registered from the digital patient records. The risks of conversion of treatment modality and shunt revision were estimated as cumulative incidences (CI’s) after 30-days, 3-, and 12 months. Results A total of 89 children with either obstructive (OH) (65%) or communicating (CH) (35%) hydrocephalus were surgically treated with VPS or ETV. Neurological disorders (CH 29%, OH 26%) and genetic conditions (CH 36%, OH 16%) were frequent concurrent conditions. Increased head size (74%) and symptoms of elevated intracranial pressure (57%) were the most common preoperative symptoms. Treatment with VPS entailed a 13.7% failure rate for OH and 9.7% for CH, whereas ETV displayed 14.3% failure rate, all reflecting failure of alleviating the preoperative clinical symptoms. The cumulative 1-year risk of shunt revision was 67%, most often due to valve dysfunction (28%), disconnection (14%), and shunt displacements (12%). Conclusion The considerable risks of treatment failure and complications call for improvements in treatment based on a better understanding of the heterogenic mechanisms of disease.

Neuroendoscopy can be learnt by assisting or doing live human surgery, cadaver dissection with or without augmented pulsatile vessel and cerebrospinal fluid (CSF) perfusion, and practicing on live animal, dead animal model, synthetic models, three-dimensional printing model with or without augmentation with animal, cadaver tissue, pulsatile vessel and reconstructed CSF model, virtual reality (VR) simulator, and hybrid simulators (combined physical model and VR model). Neurosurgery skill laboratory with basic and advanced learning should be there in all teaching hospitals. Skills can be transferred from simulation model or VR to cadaver to live surgery. Staged learning (first with simple model to learn basic endoscopic technique, then animal model, and then augmented cadavers) is the preferred method of learning. Although most surveys favor live surgery and practice on animal models and cadavers as the most preferred training model now, in future VR may also become a favored method of learning. This article is based on our experience in over 10,000 neuroendoscopic surgeries, and feedback from over 950 neuroendoscopic fellows or consultants who attended workshops conducted every 6 monthly since 2010. A literature search was done on PubMed and Google Scholar using (neuroendoscopy) AND (learning), and (neuroendoscopy) AND (training), which resulted in 121 and 213 results, respectively. Out of them, 77 articles were finally selected for this article. Most of the training programs typically focus on microneurosurgical training. There is lack of learning facilities for neuroendoscopy in most centers. Learning of neuroendoscopy differs greatly from microneurosurgery; switching from microneurosurgery to neuroendoscopy can be challenging. Postgraduate training centers should have well-equipped neuroendoscopy skill laboratory and the surgical educational curriculum should include neuroendoscopy training. Learning endoscopy is about taking advantages of the technique and overcoming the limitations of endoscopy by continuous training.
