title: Introduction of the videoscope in neurosurgery.
abstract: OBJECTIVE
  This article demonstrates that a newly developed videoscope for use in neurosurgery is effective for patients with lesions in their ventricles, cisterns, and intraparenchyma.
  
  
  METHODS
  Neuroendoscopy was performed on 13 patients using a videoscope system with narrow-band imaging technology.
  
  
  RESULTS
  The results showed that the new videoscope was far superior to conventional fiberscopes in terms of visual quality and ease of manipulation. Observation of subependymal blood vessels, which had been difficult with fiberscopes, was possible with the videoscope. Furthermore, the videoscope was capable of producing enhanced images of capillary blood vessels under the ependymal layer space if used in conjunction with narrow-band imaging technology.
  
  
  CONCLUSIONS
  This videoscope will be effective in avoiding capillary vessel injuries during neuroendoscopic procedures. It will also contribute to the future development of neuroendoscopy.
