Laparoscopic-assisted excision of sacrococcygeal teratoma in children.

BACKGROUND: Sacrococcygeal teratoma (SCT) is one of the most common tumors encountered in the neonatal period. Traditionally, a large abdominal incision is required for the combined abdominal perineal approach for the complete resection of type II-IV tumors. In this paper, we report our experience of using the combined laparoscopic perineal approach in treating these tumors.

METHODS: Between November 2000 and September 2004, 4 patients with SCT were treated by the combined approach. The operation was started with the laparoscopic mobilization of the pelvic part of the tumor, followed by the completion excision and tumor retrieval through the perineal route.

RESULTS: The operation was successfully completed in all patients, with a mean operative time of 279 minutes. There was no complication related to the laparoscopic dissection. Postoperative recovery was uneventful in all patients, except in 1 with a minor wound problem. At a median follow-up of 46.5 months, there was no recurrence encountered in all these patients and the cosmetic result was excellent. Functional outcome was satisfactory, except in the patient with spinal metastases.

CONCLUSION: The combined laparoscopic and perineal approach provides a safe, excellent access in removing type II-IV SCT in infants.
