Endoscopic Tumor Biopsy
The procedure is performed through a small incision (approximately
1 inch) behind the hairline. From this site, the endoscope
is inserted into the ventricular compartment of the brain
and then navigated toward the tumor. The tumor is readily
identified due to the difference in appearance from the surrounding
tissue. Biopsy forceps are then used to sample the tumor.
Because direct vision is being used, samples can be selected
avoiding any small blood vessels or other important structures
within the ventricle, features that cannot be done with standard
"closed" needle biopsies. The endoscope is then
removed and the wound is closed. The procedure is performed
in approximately 30 minutes and patients can return home the
following day.
