This may be useful for you.
Otherwise do a search using Google with 'neuro endoscopic surgery' [minus quotes].

hi being a medical stuent and specialising in brain surgeries i can at least define what this is . Neuroendoscopic surgery or procedures can provide histological diagnosis, define the tumor-midbrain interrelationship, and be highly effective in treating obstructive hydrocephalus and in removing tectal tumors.
