Abstract:

Robotic versus laparoscopic anterior resection for rectal cancer: A comparative study of short-term outcomes            DU Xiao-hui. Department of General Surgery，Chinese PLA General Hospital，Beijing 100853，China
Abstract    Objective    To investigate the safety and short-term outcomes of da Vinci robotic surgical system in rectal cancer radical surgery. Methods    The clinical data of 78 patients who underwent da Vinci robotic rectal anterior resection (robotic group) and 156 patients who underwent laparoscopy-assisted rectal anterior resection (laparoscopic group) from January 2012 to December 2015 in Chinese PLA General Hospital were compared retrospectively. Evaluation was focused on clinicopathological characteristics and short-term outcomes. Results    The blood loss was significant less in the robotic group than that in the laparoscopic group ［（53.9±12.4）mL vs.（75.7±58.6）mL，P=0.000］. The operating time was longer in the robotic group than that in the laparoscopic group ［（208.5±118.5） min vs.（173.7±35.4）min，P=0.003］. There was no significant difference in the time of first flatus passage，the time of first diet，the time of removing the urinary catheter，the number of retrieved lymph nodes，the postoperative complications and the length of stay（P>0.05）. In addition，the cost of surgery was significant higher in robotic group in comparison with the laparoscopic group ［(84.0±13.1) thousands yuan vs. (69.6±12.7) thousands yuan，P=0.004）. Conclusion Da Vinci robotic system is safe and feasible for patients with rectal cancer. The short-term outcomes of the robotic anterior resection of rectal cancer is identical to those of the laparoscopic operation. The long-term oncologic outcomes need the further evaluation．
