Endoscopy for tuberculous hydrocephalus

Introduction The role of endoscopy in hydrocephalus due to infectious aetiology is unclear. Tuberculous hydrocephalus is a useful model to study because it presents particular challenges and the pathophysiology of the cerebrospinal fluid disturbance is well known.Materials and methods We present the results of 24 endoscopic operations in tuberculous meningitis.Result Endoscopic third ventriculostomy (ETV) was attempted in 17 patients: seven were successful, five failed, and five were not completed due to abnormal anatomy. There were five fenestration procedures, three of which were successful. Endoscopic biopsy of two tuberculomas failed to yield a bacteriological result. These operations were more difficult to perform than for hydrocephalus due to other aetiologies.Conclusion Although ETV is technically possible in this situation, it is imperative that the patients are adequately selected for the procedure to ensure optimal treatment and that the surgeon has experience with difficult cases.
