Procedure

Sacrectomies are often performed for pelvic tumors that extend into the sacrum. Frequently, the initial step in these operations is to use an anterior approach to dissect the tumor and associated viscera away from anterior and lateral margins. The anterior approach allows identification and ligation of the internal iliac arteries that supply the gluteal vessels, which can cause significant bleeding during dissection of the lateral sacral margin.

Incision type is dictated by the need for margins. For cancer operations in which a margin is desirable, an incision that splits into a fork around the region of the interest is used. Alternatively, a midline incision can be used when margins are not required.
