title: Surgery for synchronous colorectal cancers with double colonic anastomoses: A comparison of laparoscopic and open approaches.
abstract: BACKGROUND
  The aim of this study was to evaluate the safety of laparoscopic double colon resection and synchronous anastomosis for synchronous colorectal cancer.
  
  
  METHODS
  We reviewed 42 consecutive patients who underwent double colon resection and synchronous anastomosis for synchronous colorectal cancer between 2000 and 2014. Clinical characteristics and short-term outcomes were compared between laparoscopic (n = 27) and open (n = 15) groups.
  
  
  RESULTS
  There was no conversion to open surgery in the laparoscopic group. Operating time in the laparoscopic group was significantly longer than in the open group (373 vs 292 min), but estimated blood loss was significantly lower (40 vs 179 mL). Time to first flatus (1 vs 3 days) and length of hospital stay (12 vs 17 days) were significantly shorter in the laparoscopic group. The rate of postoperative complications was similar in both groups (19% vs 27%). The anastomotic leakage rate was 3.7% in the laparoscopic group and 20.0% in the open group.
  
  
  CONCLUSIONS
  Laparoscopic surgery with double colon resection and synchronous anastomosis for synchronous colorectal cancers is safe and has greater short-term benefits than open surgery. It should be considered as a treatment option under optimal conditions.
