Methods: We delivered questionnaires about neuroendoscopic surgeries to 1,237 of Japan Neurosurgical Society certified training institutions. Results: Of these institutions, 592 (47.9%) returned completed questionnaires, and 316 (53.4%) among them experienced neuroendoscopic surgeries in the past. Two hundred seventy-six institutions had at least one procedure in the year 2003, but 208 (75.5%) had only one to ten procedures per year. Total number of procedures was 2,796, and trans-sphenoidal surgery was performed most frequently (705). Aneurysmal neck clipping (637) was second, and the third place was third ventriculostomy (ETV, 357). ETV was performed at 126 institutions, and 112 (88.9%) of them had only five cases or under per year. Discussion: Neuroendoscopic surgeries are performed at many institutions, but little experience per institution was reported. We refer to the on-going project of the Japanese Society for Neuroendoscopy on establishing training system of neuroendoscopic surgeries.
