**5.1 Novel techniques**

### **5.1.1 Single port appendectomy**

Single-port-laparoscopy for acute appendicitis is reported to be safe and effective in children (Tam et al., 2010) and adults, and may have advantages in terms of cosmetic results and patient satisfaction (Barbaros et al.; 2010; Lee YS, 2009; Raakow et al.;Tsai & Selzer, 2010). We tried this approach on two patients but could not really see the benefits. On the contrary, we believe that the single port technique is much more appropriate and ergonomic in robotic surgery. More comparative studies between the conventional technique and the single port approach are needed in order to determine its role in laparoscopic appendectomy, especially regarding long term morbidity (i.e. hernias) at the entrance site.
