Abstract    Objective    To investigate the clinical application values of complete mesocolic excision (CME) for elderly patients with colon cancer. Methods    The clinical data of 64 cases of elderly patients with colon cancer admitted between January 31, 2011 and December 31, 2011 in the Department of General Surgery, Second Hospital of Jilin University were analyzed retrospectively. All the cases were divided into two groups. Thirty-six cases were performed CME (CME group). Twenty-eight cases were performed traditional surgical resection (control group). The clinical effects of two groups were compared. Results    Mean number of lymph nodes of CME group and control group harvested (22.4±3.3) and (19.5±3.1) respectively. There was significant difference in the mean number of lymph nodes between the two groups (P=0.001).  Mean number of lymph nodes of Stage Ⅲ between the two groups harvested (23.8±3.8) and (20.7±2.7). The results showed that mean number of lymph nodes of CME group was significantly obviously higher than control group (P=0.010). The number of positive lymph nodes of Stage Ⅲ between the two groups harvested (3.4±2.3) and (2.1±1.4). The results showed that mean number of positive lymph nodes of CME group was significantly obviously higher than control group (P=0.047).  Mean blood loss of CME group was significantly obviously less than control group（P=0.020). But there was no significant difference in the overall postoperative complication incidence between two groups（P=0.628). Conclusion    CME for colon cancer in elderly patients is better than traditional surgery without more operation risk or postoperative complication incidence.
