Core Tip

Core tip: Rectal cancer is one of the most complex diseases as it combines oncological, anatomical, and functional challenges with a variety of technical and multimodality treatment options. While open surgery was long considered the surgical gold standard, less invasive approaches have evolved. These newer technologies have attractive advantages, however their overall benefit and risk analysis in the short and long run and their specific role for rectal cancer remain controversial and a matter of further research.
