Endoscopic Port Surgery for Intraparenchymal Brain Tumors

Intraparenchymal endoscopic port surgery (EPS) is a minimally-invasive technique for the removal of brain tumors and other mass lesions. The operation is made feasible through the combination of multiple technologies including image-guidance, parallel endoscopy, and cylindrical brain retraction. Tumors with an overlying cuff of normal brain parenchyma, soft consistency, and low or moderate vascularity are the ideal candidates. Techniques for tumor removal using the endoscopic port and prevention of peri-operative morbidity are discussed. In selected cases, EPS can provide superior visualization and decreased white matter manipulation during intra-parenchymal tumor resection when compared with conventional approaches using the operating microscope.
