The surgical workforce is ageing. This will impact on future workforce supply and planning, as well as the professional performance and welfare of surgeons themselves. This paper is a 'call to arms' to surgeons to consider the complex problem of advancing years and surgical performance.

The development of electromagnetic neuronavigation has allowed the use of image-guided navigation in the very young patient in whom rigid fixation in cranial pins is contraindicated. The technique and the authors' experience of its use in a series of paediatric patients are described.
View Article and Find Full Text PDFObjective: To describe the short-term operative success and the long-term reliability of endoscopic third ventriculostomy (ETV) for treatment of hydrocephalus and to examine the influence of diagnosis, age, and previous shunt history on these outcomes.
Methods: We retrospectively analyzed 203 consecutive patients from a single institution who had ETV as long as 22.6 years earlier.
Objective: To describe the short-term operative success and the long-term reliability of endoscopic third ventriculostomy (ETV) for treatment of hydrocephalus and to examine the influence of diagnosis, age, and previous shunt history on these outcomes.
Methods: We retrospectively analyzed 203 consecutive patients from a single institution who had ETV as long as 22.6 years earlier.
Objective: Late failure after successful third ventriculostomy is rare, and death caused by failure of a previously successful third ventriculostomy has been reported on four occasions. We describe a simple innovation that adds little morbidity and has the potential to reduce the advent of death after late failure of endoscopic third ventriculostomy.
Methods: After endoscopic fenestration of the floor of the third ventricle, a ventricular catheter and subcutaneous reservoir are placed via the endoscope path.
