Purpose: 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. Conclusion: 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.
