Objectives: The objectives of this study was to investigate the current status of neuroendoscopic surgery in Japan and to discuss the issue disclosed by the survey.
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.

Neuroendoscopic lavage for posthemorrhagic hydrocephalus of prematurity: preliminary results at a single institution in the United States.

Objective: The current neurosurgical treatment for intraventricular hemorrhage (IVH) of prematurity resulting in posthemorrhagic hydrocephalus (PHH) seeks to reduce intracranial pressure with temporary and then permanent CSF diversion. In contrast, neuroendoscopic lavage (NEL) directly addresses the intraventricular blood that is hypothesized to damage the ependyma and parenchyma, leading to ventricular dilation and hydrocephalus. The authors sought to determine the feasibility of NEL in PHH.

To explore techniques, advantages and disadvantages of 3D Slicer reconstruction and 3D printing localization technology combined with transcranial neuroendoscopy in ventriculoperitoneal shunt surgery. Retrospective analysis of clinical data of patients with hydrocephalus treated by ventriculoperitoneal shunt surgery using 3D Slicer reconstruction and 3D printing positioning technology combined with transcranial neuroendoscopy in our hospital from October 2021 to March 2023. A total of 33 patients with complete data were collected, including 19 males and 14 females, aged 10-81 years.

Acute presentation of cystic craniopharyngioma is a potentially life-threatening condition, characterized by disability and increased mortality risk, often caused by large cysts with or without hydrocephalus. This study evaluated the applicability of minimally invasive neuroendoscopic surgery (NES) for rapid intracranial pressure relief and tumor control as an alternative to emergent microsurgical resection. A retrospective review of the electronic medical record database of patients with craniopharyngiomas treated at our institution between June 2007 and October 2024 identified 13 non-consecutive cases of acute presentation of cystic craniopharyngioma managed with NES.

Basal ganglia hemorrhage (BGH) is a prevalent site for intracerebral hemorrhage. Although neuroendoscopy (NE) surgery has emerged as a less invasive alternative to craniotomy (CT), the optimal surgical method remains debatable. This systematic review and meta-analysis aimed to compare the efficacy and safety of NE versus CT in the management of BGH.

Objective: This study aims to comprehensively evaluate the complications, effectiveness, and safety of neuroendoscopic surgery (NS) assisted by 3DSlicer software, compared to traditional surgery in patients with intracerebral hemorrhage (IH).
Methods: We searched for case-control trials from the Chinese Biomedical Literature data (CBM) online database, Wanfang Database, EMBASE, VIP Full-text Database, China National Knowledge Infrastructure (CNKI), Science Direct, Cochrane Library, and PubMed. The studies, published since January 2010, involved NS or traditional surgery for IH patients assisted by 3DSlicer software.
