Abstract    The occurrence of primary retroperitoneal tumors is rare. Laparoscopic resection of retroperitoneal tumors has been described in recent years. Both transperitoneal and retroperitoneal approaches can be used in laparoscopic resection for retroperitoneal tumors. For an experienced surgeon who is familiar with laparoscopic skills and anatomy of the retroperitoneal spaces, laparoscopic resection of retroperitoneal tumors can be performed safely in selected patients.
