Influence of type and volume of surgical resection on postoperative period in patients with gliomas

Abstract

283 patients with gliomas were included in this study. Age, sex, neurological status and Karnovsky performance were analyzed before and after surgery, also tumor location, type and volume of surgical resection, postoperative complications were considered. Volume of tumor resection did not depend on glioma localization, excluding deep located tumors, in which case stereotactic cryotomy was performed (p < 0,01). In cases of stereotactic cryotomy postoperative neurological deficit worsening was noted in 12,5%, in patients with open biopsy and partial resection — 10,9%, and in case of total or subtotal tumor resection in 7,0% (p > 0,05). Partial gliom resection often related with postoperative complications and neurological deficit worsening then open surgery total tumour resection. Stereotactic cryotomy does not lead to bigger postoperative complications frequency in comparisons with open surgery.
