Endoscopic systems have now been used with relatively low complication rates in numerous situations including the aspiration and resection of colloid cysts of the third ventricle, biopsy and resection of cystic and intraventricular tumours, evacuation of intracerebral haematomas, and a terminal third ventriculostomy through the foramen of Monro for hydrocephalus. In this paper. we present our experience in two cases, the retrieval of a retained ventricular catheter and the drainage of an intracerebral abscess respectively.
