Surgical approach included transsacral approach (52 cases), transabdominal approach (eight cases), and combined approach (two cases). A total of 48 benign lesions (77.4%) and 14 malignant lesions (22.6%) were confirmed by histological examination. The 48 benign cases included dermoid cysts (17 cases), simple cysts (eight cases), teratomas (eight cases), neurofibromas (eight cases), fibrolipomas (four cases), neurilemmomas (two cases), and synovioma (one case). The 14 malignant cases included lymphomas (four cases), malignant teratomas (three cases), fibrosarcomas (two cases), interstitialomas (four cases) and malignant mesothelioma (one case). Complications occurred in 14.5% of patients and included intraoperative bleeding (three cases), rectal injury (three cases), and presacral infection (three cases).Conclusion: Primary retrorectal tumors are very rare. Successful treatment of these tumors requires extensive knowledge of pelvic anatomy and expertise in pelvic surgery.Keywords: retrorectal space, retrorectal tumor, surgical treatment |
