The Era of Neuroendoscopy: Just How Far Can We Go?

La neuroendoscopia: una técnica revolucionaria en el campo de la neurocirugía

La neuroendoscopia es un procedimiento mínimamente invasivo que se desarrolló a principios del siglo pasado y tiene importancia en el campo de la neurocirugía, representa un método innovador ya que aporta una amplia visualización de las estructuras anatómicas con mínimo traumatismo del tejido nervioso, contribuyendo al diagnóstico y tratamiento de diversas afecciones intra y extracraneales. Se realizó una búsqueda bibliográfica con el propósito de identificar, analizar y describir algunas patologías neuroquirúrgicas que se han tratado bajo neuroendoscopia, así como los aportes más relevantes en cirugía pediátrica y de columna, con el fin de exponer el impacto que ha tenido esta técnica en el desarrollo de la cirugía moderna.

Application of osteoinductive calcium phosphate ceramics in children's endoscopic neurosurgery: report of five cases

This work aimed at investigating the possibility and effectiveness of osteoinductive calcium phosphate (CaP) ceramics to close the drilled skull holes and prevent the postoperative cerebrospinal fluid (CSF) leaking in children’s endoscopic neurosurgery. Five children patients (four boys and one girl, 3- to 8-years old) underwent the surgery, in which the endoscopic third ventriculostomy (ETV) was operated in four cases of hydrocephalus, and biopsy and ETV were both performed in one case of pineal tumor. The drilled skull holes were filled with the commercial osteoinductive CaP ceramics. The patients were followed up by CT scan at 1, 7 days, 3 and 6 months postoperatively. All the five cases were successful, and the holes were closed well after filled with the ceramics. The follow-up survey showed that no CSF leaking or rejection reaction was found. The CT scan indicated that the drilled holes began healing at 7 days postoperatively, and a relatively complete healing happened at 6 months postoperatively. The excellent ability of the CaP ceramics to induce bone regeneration was also confirmed by repairing the skull defects in a monkey model. The results of μ-CT and histological analysis showed that a bony structure with irregular array occurred at the defect area, and the newly formed bone volume density reached 65.7%. In conclusion, the osteoinductive CaP ceramics could be an ideal material to treat the drilled skull holes in children’s endoscopic neurosurgery and prevent CSF leaking afterwards. However, further investigation with more cases and longer follow-up was required to evaluate the clinical effect.

Neuroendoscopy in Kuwait: Evolution, Current Status, and Future Directions

An overview of the development of neuroendoscopy at the neurosurgery department, Ibn Sina Hospital in Kuwait, is presented with an outline of difficulties and obstacles faced by the field until it reached its current status. The factors and solutions that helped us overcome these problems are also elaborated on. After a modest beginning few years ago, endoscopic skull base procedures, intraventricular neuroendoscopy, and spinal endoscopy are regularly performed in the department. Although neuroendoscopy is not per se a neurosurgical subspecialty, it is an area that requires special training. Achieving an appropriate level of care necessitates these highly trained neurosurgeons to collaborate together and with other specialties to create teamsgeared towards offering such treatment options topatients. Importantly, a multitude of essential facilities should be available to make such a pattern of practice possible. In our experience, this was made possible through continued efforts that have finally paid off and gradually led to a complete shift of the face of neuroendoscopic practice in our department. Our future endeavors aim at further development of neuroendoscopy in the department to create a center of excellence.
