Neuroendoscopy: one year of experience--personal results, observations and limits.

After reading reports of successful neuroendoscopic treatment of hydrocephalus, colloid cysts and arachnoid cysts as well as tumor biopsy, we started using endoscopic procedures in our Department, one year ago. One surgeon (E.S.) skilled in the Decq Endoscope, performed a series of sixteen procedures, from January 2001 to March 2002 (in patients aged 28 to 69 years). The most common pathology was obstructive hydrocephalus (14 cases), one was colloid cyst, and the last case was tumor biopsy. The surgical treatment consisted of third ventriculostomy, cyst opening and shrinking and tumor biopsy. In fourteen patients treated for hydrocephalus with third ventriculostomy (ETV), one required a definitive shunt. Complication occurred in one case with chronic subdural collection. We further report one case of aqueductal restoration after third ventriculostomy. Our results, with no neurological deficits or deaths, confirmed our opinion that neuroendoscopy is a safe surgical technique in well-selected patients and we believe it is the ideal treatment in obstructive hydrocephalus.
