Sacral resection. Operative technique and outcome.

Tumors involving the sacrum are difficult to treat. These include both primary tumors of the sacrum and locally invasive colorectal carcinomas. Sacral resection is often the only effective alternative for meaningful palliation or cure of sacral tumors. A review of 20 cases of sacral resections for primary sacral tumors (8) and locally invasive anorectal cancers (12) is presented. The mortality (0%) and morbidity (35% urinary complications, 25% wound disruptions, 1600-mL median blood loss) compare favorably with reports in the literature. Long-term survival was achieved with primary tumors of the sacrum. Local control of disease was achieved in the majority of patients with rectal cancer, with good palliation of preoperative pain. Long-term survival, however, is rare in this group. Surgical resection of sacral tumors can be undertaken with acceptable morbidity and mortality in selected patients.
