title: Oncologic Outcomes of a Laparoscopic Right Hemicolectomy for Colon Cancer: Results of a 3-Year Follow-up.
abstract: OBJECTIVE
  The purpose of the study is to evaluate the oncologic outcomes of a laparoscopic-assisted right hemicolectomy for the treatment of colon cancer and compare the results with those of previous randomized trials.
  
  
  METHODS
  From June 2006, to December 2008, 156 consecutive patients who underwent a laparoscopic right hemicolectomy with a curative intent for colon cancer were evaluated. The clinicopatholgic outcomes and the oncologic outcomes were evaluated retrospectively by using electronic medical records.
  
  
  RESULTS
  There were 84 male patients and 72 female patients. The mean possible length of stay was 7.0 ± 1.5 days (range, 4 to 12 days). The conversion rate was 3.2%. The total number of complications was 30 (19.2%). Anastomotic leakage was not noted. There was no mortality within 30 days. The 3-year overall survival rate of all stages was 93.3%. The 3-year overall survival rates according to stages were 100% in stage I, 97.3% in stage II, and 84.8% in stage III. The 3-year disease-free survival rate of all stages was 86.1%. The 3-year disease-free survival rates according to stage were 96.2% in stage I, 90.3% in stage II, and 75.6% in stage III. The mean follow-up period was 36.3 (3 to 60) months.
  
  
  CONCLUSIONS
  A laparoscopic right hemicolectomy for the treatment of colon cancer is technically feasible and safe to perform in terms of oncologic outcomes. The present data support previously reported randomized trials.
