Brief Summary:

Right-sided colonic cancer is treated with right-sided colectomy, predominantly performed as minimally invasive surgery with extracorporeal anastomosis (ECA). In recent years a new technique with intracorporeal anastomosis (ICA) has emerged and it is thought that ICA is less invasive and thereby has the potential to improve the postoperative course of right colonic cancer patients.

The objective of this study is to compare robotic right colectomy with either ICA or ECA in a randomized controlled setting.
