Abstract: ［Abstract］ Objective To investigate the safety， feasibility of totally laparoscopic right colectomy （TLRC） in elderly patients with colon cancer. Methods Eighty elderly patients with right?sided colon cancer from February 2017 to November 2018 were randomized into the observation group and the control group. Patients in the observation group were assigned to undergo totally laparoscopic right colectomy （TLRC）， Patients in the control group were assigned to undergo laparoscopic?assisted right colectomy （LARC）. The terms of demography， American Society of Anesthesiologists （ASA） classification， preoperative stage distribution（TNM）， details of operations， post?operative recovery， and postoperative complications were recorded and analyzed. Results No significant differences were found among preoperative clinical data （P>0.05）. There were no significant differences among the groups in terms of average operative time， blood loss， lymph node harvest，specimen length， time to hospital stay （P>0.05）. There were significant differences in the length of mini?laparotomy between the observation group and the control group （4.2±0.8 vs 5.9±0.7 cm， P<0.00）.Timing of first flatus （2.5±1.4 vs 3.2±1.3 d， P<0.05） and time to liquid diet （2.6±1.4 vs 3.2±1.4 d， P<0.05） were statistically lower in observation group. There were no significant differences between the two groups for post?operative complications （12.5% vs 15.0%， P>0.05）. Conclusion TLRC in elderly patients with colon cancer is safe and feasible， and is better in post?operative recovery.
