[Investigation of resection and reconstruction procedure of high-sacrum tumors].

Objective: To investigate the way of resection of high-sacrum tumors and the way and duration of the spinal-pelvic TSRH or ISOLA internal fixation.
Method: From October 1998 through April 2002, 35 patients with sacral tumor were enrolled in our hospital, including 4 cases in L(5)-S(1), 2 in L(5)-S(2), 4 in S(1), 8 in S(1 - 2), 6 in S(1 - 3), 6 in S(1 - 4), 5 in S(1 - 5). 35 patients were followed by lumbo-pelvic TSRH or ISOLA internal fixation and corresponding chemotherapy and radiotherapy.
Results: In the follow-up period of 6 - 42 months, the short-term results were satisfactory with the lumbosacral pain reduced and the neurological function improved in different degrees, however dysuria occurred in 1 case and skin necrobiosis at coccygeal incision occurred in 1 case; two cases experienced cerebrospinal fluid leakage and 1 case experienced postoperative infection and delayed healing, 1 case with chordoma and 2 cases with malignant fibrous histiocytoma recurred 1 year after postoperation, one of these 2 cases with malignant fibrous histiocytoma suffered from lung metastasis and died of system failure 19 months after postoperation. No fractured rod occurred.
Conclusion: Surgical procedure and postoperative comprehensive treatment have important effects on the prognosis. High-sacral tumor resection and reconstruction are effective means of achieving stabilization, providing significant pain relief and preserving ambulatory capacity.
