Surgical treatment of pediatric retroperitoneal tumors with invasion of major blood vessels: a single-center experience

BACKGROUND: This study assessed operative experiences with common pediatric retroperitoneal tumors invading major blood vessels. METHODS: Forty-seven pediatric patients with retroperitoneal tumors were enrolled. They included 22 neuroblastomas, 6 gangliocytomas and 19 Wilms' tumors, and underwent primary surgical resection after vascular skeletonization and manipulations of involved vessels. RESULTS: In the above tumors, the one-stage gross total resection rates of, respectively, 95.45%, 100% and 100% were obtained. There was only one complication, namely post-operational early acute renal failure that recovered with dialysis. There were no deaths. CONCLUSIONS: Vascular skeletonization and other vessel manipulations prior to surgery improve the gross total resection rates of pediatric retroperitoneal tumors.
