Objectives: To show the current activities and future perspectives of the endoscopic surgery for tumors in and around the third ventricle.
Method: During five years, 23 consecutive patients with tumor in and around the third ventricle underwent endoscopic tumor resection. We used both a flexible- (VISERA video scope, Olympus Co. Ltd., Japan) and a rigid endoscope (Endoarm, Olympus Co. Ltd., Japan) depending on the lesion.
Results: Seven patients were operated on via the single burr-hole approach using a flexible endoscope to perform a biopsy of the tumor, as well as the third ventriculostomy. In all seven patients, a sampling of tumor tissue was successfully performed. Sixteen patients underwent endoscopic surgery using a rigid scope via various entry routes (endonasal: 6, transventricular: 4, combined endonasal and trasnventricular: 1, infratentorial supracellebellar: 1, occipital transtentorial: 3, and interhemispheric: 1 toward the third ventricle. Using a rigid endoscope, we could achieve extensive removal of the tumor with a clear vision, and 81.3% underwent gross total (10/16) and subtotal (3/16) resection.
Conclusions: The endoscopic surgery is safe and feasible for the third ventricle tumors. Using endoscope, we can choose 360-degree surgical corridor to the third ventricle depending on the tumor characteristics.
