[Surgical treatment for complex pediatric retroperitoneal tumors]

To explore and summarize the experience of surgical treatment for primary retroperitoneal tumor (PRT)in children.

Clinical data of 17 patients with PRT treated from January 2001 to January 2008 were retrospectively analyzed, including image examination, pathologic examination and surgical procedure.

Seventeen patients underwent complete resection; 8 benign PRT, and 9 malignant PRT were diagnosed by operation and postoperative pathologic examination. Vascular surgery was done on 11 patients, 6 cases of multi-visceral resection, 1 vascular transplant, and 1 multi-visceral resection. Two patients had recurrent malignant PRT.

For pediatric complex retroperitoneal tumors, complete resection can reduce the recurrence and improve the long-term survival.
