The Gore-Tex biomaterial mesh as temporary divisor in two times surgery for spinal and pelvic tumors.

In muscular skeletal spine and pelvic tumor, surgery can be performed by a double anterior and posterior approach to decrease the risk of bleeding and opening the tumor; in first one, neurovascular bundles are divided by the mass; in second one, the tumor is resected by posterior or postero-lateral approach. A Gore-Tex mesh could be used as divisor between neurovascular bundles and the tumor to decrease the adhesion formation risk and facilitate tumor removal during second operation if performed after more days. The cohort was composed by a consecutive series of 11 patients underwent to surgery for spine and pelvic tumor where Gore-Tex mesh spacer was placed. In this study, efficiency and tolerability of Gore-Tex mesh were evaluated. No case of adhesion between Gore-Tex mesh and surrounding structures is reported, no case of migration or complications occurred. Gore-Tex mesh use can be considered a useful and safe procedure to decrease the risk of adhesion formation between tumor and surrounding tissue so that to allow the tumor removal easier.
