title: Reduced port laparoscopic surgery for colon cancer is safe and feasible in terms of short-term outcomes: comparative study with conventional multiport laparoscopic surgery.
abstract: OBJECTIVE
  Laparoscopic surgery was previously accepted as an alternative surgical option in treatment for colorectal cancer. Nowadays, single-port laparoscopic surgery (SPLS) is introduced as a method to maximize advantages of minimally invasive surgery. However, SPLS has several limitations compared to conventional multiport laparoscopic surgery (CMLS). To overcome those limitations of SPLS, reduced port laparoscopic surgery (RPLS) was introduced. This study aimed at evaluating the short-term outcomes of RPLS.
  
  
  METHODS
  Patients who underwent CMLS and RPLS of colon cancer between August 2011 and December 2013 were included in this study. Short-term clinical and pathological outcome were compared between the 2 groups.
  
  
  RESULTS
  Thirty-two patients underwent RPLS and 217 patients underwent CMLS. Shorter operation time, less blood loss, and faster bowel movement were shown in RPLS group in this study. In terms of postoperative pain, numeric rating scale (NRS) of RPLS was lower than that of CMLS. Significant differences were shown in terms of tumor size, harvested lymph node, perineural invasion, and pathological stage. No significant differences were confirmed in terms of other surgical outcomes.
  
  
  CONCLUSIONS
  In this study, RPLS was technically feasible and safe. Especially in terms of postoperative pain, RPLS was comparable to CMLS. RPLS may be a feasible alternative option in selected patients with colon cancer.
