title: Minimally invasive surgery for rectal cancer.
abstract: The present scarcity of literature on laparoscopic rectal cancer surgery makes it premature to determine whether laparoscopic surgery should be the standard of care for rectal cancer. Notwithstanding that, the available evidence proves its safety and adequate oncological clearance. Moreover, current data do not suggest any detrimental effect on the postoperative and early oncological outcomes. On the contrary, there is level three evidence showing that laparoscopic technique results in less blood loss, shorter length of stay, and reduced abdominal wound disorders and pulmonary complications, albeit the overall morbidity remains similar to that of open surgery. Long-term survival outcomes remain largely unclear, however. Hence, it is high time that laparoscopic technique should be further evaluated, preferably by means of large-scale randomized trials, to define its exact role in the treatment of rectal cancer.
