title: A Comparison of Open, Laparoscopic, and Robotic Surgery in the Treatment of Right-sided Colon Cancer.
abstract: BACKGROUND
  Multidimensional comparison between open, laparoscopy, and robotic surgery in the management of right-sided colon cancer are lacking. The aim of this study was to compare the early perioperative results and oncologic outcomes among the 3 different methods.
  
  
  METHODS
  Between June 2007 and 2011, a total of 96 patients who underwent right hemicolectomy in a single institution were classified into the open surgery (OS; n=33), the laparoscopy surgery (LS; n=43), and the robot surgery (RS; n=20) groups. Perioperative and oncologic outcomes were compared among the 3 groups.
  
  
  RESULTS
  Patient demographics were comparable. Operation time was significantly longer in the RS and LS than the OS (P<0.001). There was 1 OS conversion in LS. There was no difference of total retrieved lymph node numbers among the 3 groups. Postoperative recovery was faster and hospital stay was shorter in RS than OS. However, there was no difference between LS and RS. After the median 40 months' follow-up, 5-year disease-free survival was similar among the OS, LS, and RS (87.7%, 84%, and 89.5%, respectively). Total charge and total patient charge were significantly higher in RS than the others.
  
  
  CONCLUSIONS
  Our comparative study demonstrates that the RS have better short-term outcomes in reducing hospital stay compared with the OS, but similar to the LS. Although the oncologic outcomes are similar, the benefit of RS in right hemicolectomy is unclear considering a high cost of RS.
