title: Single-port versus multi-port laparoscopic surgery for colon cancer in elderly patients.
abstract: The safety of single-incision laparoscopic surgery (SLS) in elderly patients with colorectal cancer has not been established. The aim of the current study was to compare the outcomes of SLS and multi-port laparoscopic surgery (MLS) and to assess the feasibility of SLS in colorectal cancer patients aged ≥70 years. A retrospective case-control study of colon cancer patients undergoing elective surgical intervention between 2011 and 2014 was conducted. A total of 129 patients with colon cancer underwent surgery and were included in the analysis. Data regarding patient demographics, surgical variables, oncological outcomes and short-term outcomes were evaluated for statistical significance to compare MLS (n=79) and SLS (n=50) in colon cancer patients. No significant differences were observed in patient characteristics. No case required re-admission within 30 days post surgery. The mean surgery times were similar for the MLS and SLS groups when cases with left and right hemicolectomies were combined (207.7 and 215.9 min, respectively; P=0.47). In addition, overall perioperative outcomes, including blood loss, number of lymph nodes harvested, size of the surgical margin and complications, were similar between these groups. Thus, we suggest that SLS can be performed safely in elderly patients with colon cancer.
