laparoscopic surgery for retroperitoneal masses in the hands of In conclusion, laparoscopic approach is a valid alternative
an experienced team. It seems that laparoscopy can offer clinical to open procedures in selected patients with retroperitoneal
outcomes comparable to open procedures in terms of disease masses. In our experience, laparoscopy offers a viable and
control and better outcomes in terms of hospital stay, analgesic oncologically radical option with excellent results and low

advantages of minimally invasive surgery can be extended to more common practice as the experience grows and new
selected patients with retroperitoneal masses. technologies become available.
