Transsacrococcygeal approach for resection of retrorectal tumors.

Retrorectal tumors, are a rare and interesting entity, traditionally managed with surgery. The surgical approach is a key to get an easy and safe access. The purpose of this study was to evaluate the results of resection by a transsacrococcygeal approach. Thirty-six patients had retrorectal tumors resected by a transsacrococcygeal approach in our department. All the tumors were en bloc resected, irrespective of size and anatomical depth. The clinic data were retrospectively reviewed. Tumor mean size was 10 ± 4.4 cm. In 16 cases, tumors were 10 cm or more in size. The largest tumor measured 20 cm. The estimated mean blood loss was 130 ml. No mortality and severe postoperative complications were observed. The most significant issues were wound infection and delayed healing. Pathology showed 15 cases of epidermal cysts, two cases of enterogenous cyst, one case of bronchogenic cyst, 12 cases of teratoma, two cases of schwannoma, two cases of low-grade malignant fibrous myxoma, one case of aggressive angiomyxoma, one case of desmoid tumor. The transsacrococcygeal approach gives an easy access and good visualization with fewer complications. This surgical approach shows to be safe and effective for resection of retrorectal tumors.
