Surgical quality assurance in rectal cancer treatment: the key to improved outcome.

Surgery is the key to cure for patients with rectal cancer. Surgical techniques are evolving with conventional blunt dissection being increasingly abandoned for the sake of total mesorectal excision (TME), leading to favourable clinical and functional outcome. Surgical quality assurance programmes, involving training of general surgeons to adopt the TME technique, have proven to be feasible and result in improved outcome compared to historical controls. In this overview, developments in rectal cancer treatment are highlighted, the relation of surgeon and/or hospital volume with treatment outcome is discussed, and future directions in optimising rectal cancer treatment are considered.
