Posterior sagittal approach for resection of sacrococcygeal teratomas.

The aim is to evaluate the ease of access, surgical trauma and cosmetic results of posterior sagittal approach for sacrococygeal teratomas (SCTs). From January 2002 to June 2010, we operated 19 cases of SCT exclusively through posterior sagittal approach. Patients were placed in knee chest position. An elliptical incision was made for the excision of the tumor. Care was taken to preserve all the muscles and other vital tissue in this area. Coccygectomy was performed in all patients. Closure was performed in layers. It was possible to resect all tumors from this approach and none of the patients required revision of the incision. Complete resection was possible in 17 patients while two had residual disease due to local extension. Minimal wound dehiscence was noted in four patients that healed spontaneously. It was possible to perform excision even in very large masses. Wound scar was satisfactory in most patients with preservation of gluteal folds. It is therefore concluded that posterior sagittal approach for SCT is feasible, with good access and cosmetic results.
