Impact on clinical practice and healthcare system SPA Surgery is an emergent frontier of surgical innovation and represents an alternative to multi-ports standard laparoscopy. The trans-umbilical technique allows to perform laparoscopy with the supposed benefit of reduced invasiveness. In recent literature a large number of studies have aimed to demonstrate feasibility and safety of the new method even if no randomized trial is still available for definitive conclusions. Once feasibility and safety will be shown we will have to investigate benefit for the patients. For these reasons we have chosen as primary endpoint overall morbidity while in order to demonstrate the supposed benefit (patient's reduced discomfort and better cosmetic outcome) and skin incision morbidity will be taken into consideration.
