Benefits of routine laparoscopic procedures, such as reduced pain, decreased length of hospitalization, and quicker return to normal activities, have resulted in substantial extension of indications, including routine laparoscopic resection of both benign and malignant intraabdominal tumors. Initial concern regarding such procedures focused largely on whether they constituted satisfactory anticancer operations. Recent data have largely assuaged these fears. However, the optimal approach for removal of otherwise undefined retroperitoneal tumors remains less well delineated.
