Abstract    Objective    To compare the short-time and long-time outcomes between laparoscopic-assisted right hemi-colectomy (LR group) and open right hemi-colectomy (OR group) for colon carcinoma. Methods    Between June 2003 and September 2010, 324 patients with colon cancer underwent OR or LR in the same hospital, 177 cases treated by LR and 147 cases by OR. Retrospective analyses the differences between the two groups in clinical data, operative date, complications and follow-up data. Results    There are no differences between the two groups in perioperative clinical data; The recovery time was significantly shorter in LR group; The number of all lymph nodes harvestedin LR group was significantly more than OR group (15.2±10.1vs11.4±4.1);The incidence of postoperative complications in LR group was significantly less than OR group (12.99%vs22.45%).Local recurrence and metachronousmetastasis rate in LR group was less than OR group, but the differences were not significant. Cumulative overall survival for all stages at 1, 3 and 5 years of LR group (97.18%, 83.73% and 70.37%) were no significantly different compared to the OR group (94.56%, 77.84% and 66.97%). Conclusion    laparoscopic-assisted right hemi-colectomyfor colon cancer is safe and effective, it is superior to open surgery in short-term outcomes, and equal to open surgery in long-term outcomes.
