Safety and Feasibility of Single-port Surgery for Colon Cancer in Octogenarians

Background/Aim: The use of single-port surgery (SPS) in elderly patients with colon cancer remains controversial. The aim of this study was to evaluate the clinical outcomes of elderly patients who underwent SPS. Patients and Methods: Consecutive patients >80 years old of age who underwent SPS (n=86) or multi-port surgery (MPS) (n=40) for colon cancer from January 2008 to December 2014 were analyzed. Short-term and long-term outcomes were compared between groups. Results: The morbidity rate in the SPS was significantly lower than that in the MPS (p=0.027). Length of hospital stay in the SPS was significantly shorter than that in the MPS (p=0.016). Similar oncological outcomes were observed in the groups. The 3-year disease-free survival rate, the 5-year overall survival rate and the 5-year cancer-specific survival rate did not differ significantly between groups. Conclusion: SPS is safe and can provide clinical outcomes comparable to those of MPS in octogenarians with colon cancer.
