Background and Aim: Recent reports have been showed that reduced-port surgery with single-port access (SPA) offers more cosmetic advantages compared to conventional multi-port laparoscopic surgery (CLS) even in the surgical treatment for colon cancers. However, SPA still has the technical restrictions to maintain surgical quality and with additional access device, it could make the laparoscopic operation easy and feasible. The aim of this study is to compare the short-term results between SPA and SPA plus one needle devices for colon cancers.

Methods: Seventeen patients were included in the current study between May 2010 and June 2012. SPA was performed in 10 patients and SPA plus one needle device in 7 patients. We compared the clinical variables such as operating time, blood loss, number of retrieved lymph node, morbidity, mortality and length of hospital stay among the two groups. All patients underwent laparoscopic colectomy for right-sided colon cancer.

Results: There was no statistically significant differences of clinical backgrounds among the two groups; gender (20.0 vs. 57.1 % males, p = 0.288), age (median age 65.5 vs. 62 years, p = 0.790), clinical stage (I: 50 vs. 14.3 %; II: 10 vs. 57.1 %; III :40 vs. 28.6 %, p = 0.109), body mass index (21.2 vs.25.0 kg/m2, p = 0.591), and mean diameter of tumor(30.0 vs.29.2 mm, p = 0.827). We had no conversions to open surgery in all procedures and one conversion in SPA to CLS. No mortality was found in this study. Short-term outcomes were comparable in the two groups as follows; mean operating time (155.1 vs. 157.4 min, p = 0.807), mean blood loss (36.6 vs. 69.1 g, p = 0.435), median post-operative hospital stay (7 vs. 7 days, p = 0.671), number of lymph node retrieval (22.5 vs. 20, p=0.624) and morbidity (10 vs. 14.3 %, p = 0.621).

Conclusions: SPA plus one needle procedure for right-sided colon cancer showed the same short-term outcomes as SPA. An additional needle usage result not in the same cosmetic status but in feasible outcomes with less stress during surgery.
