Neuro-endoscopic surgery--experience and outcome analysis of 102 consecutive procedures in a busy neurosurgical centre of India

BACKGROUND: Neuro-endoscopic surgery is finding increasing application for various clinical conditions. We present our experience of 100 cases of diverse intracranial lesions, including infections, managed by neuro-endoscopy in a busy neurosurgical department in the developing world. MATERIAL AND METHODS: One hundred patients treated from March 1996 to February 2002 formed the study group. Management of hydrocephalous by Endoscopic third ventriculostomy (ETV) was the aim in 75 patients with or without diagnostic biopsy. Excision or resection was attempted in 25 patients with juxtaventricular or intraventricular lesions. Endoscopic procedures included total tumour resection, partial resection, biopsy, stent placement, Monroplasty, septostomy and third ventriculostomy. Outcomes of endoscopic surgery were evaluated with respect to clinical and/or radiological improvement, complications and need for additional therapy. FINDINGS: Endoscopy was the only surgical treatment in 59 patients. Intermittent lumbar drainage for cerebrospinal fluid leak, shunt, microsurgery and/or repeat endoscopic surgery were additional treatments needed in 39 patients, who subsequently had increased hospital stay, postoperative morbidity and a higher cost of treatment. Peroperative bleeding due to distorted anatomy and obscured vision in 2 patients with post-infective loculated hydrocephalus (LH) resulted in two fatalities (2%) in the early post-operative period. INTERPRETATION: Neuro-endoscopic surgery cuts down operative time and hospital stay, reduces cost and results in a faster turnover of the patients. It is a versatile and useful tool for a busy neurosurgical department.
