Abstract

Background: Laparoscopic surgery is a minimally invasive and frequently performed surgical procedure that has become the standard surgery for colorectal cancer. Needlescopic surgery (NS) for colon cancer has also been performed and reported as a less invasive technique. In this study, we investigated the long-term outcomes of NS in comparison with those of conventional surgery (CS). Methods: The data of 1122 patients without distant metastasis who underwent laparoscopic surgery between 2011 and 2014 were retrospectively analyzed. In this study, NS was defined as a laparoscopic procedure performed with the use of 3-mm ports and forceps with one 5-mm port for an energy device, as well as with clips. One 12-mm port was placed in the umbilicus for specimen extraction from the abdominal cavity. Results: A total of 241 patients underwent NS. There was no significant difference between the 5-year recurrence rate and the 5-year total mortality rate (NS: 10.0% and 5.4% vs. CS: 10.3% and 3.5%, p = 0.86/0.23). In the multivariate analysis, NS was not found to be an independent prognostic factor. In terms of the distribution of recurrence sites, there was no significant difference between the two groups. Conclusions: NS for colon cancer was not inferior to CS in terms of short-term and long-term outcomes.
