Prete FP, et al. - Researchers performed an evaluation of the safety and efficacy of elective rectal resection for rectal cancer in adults by robotic surgery compared with conventional laparoscopic surgery. Evidence of moderate quality support that compared to conventional laparoscopic surgery, robotic surgery for rectal cancer produced similar perioperative outcomes of oncologic procedure adequacy. Robotic surgery resulted in lower rate of conversion to open surgery, however, it was observed to had significantly longer operating time than laparoscopic approach.
