Clinical Outcome of Single-port Surgery in Patients With Pathologic T4 Colon Cancer

Purpose: The aim of this study was to evaluate the clinical outcomes of single-port surgery (SPS), compared with those of multiport surgery (MPS) in patients with pathologic T4 colon cancer. Materials and Methods: A total of 188 patients with proven pathologic T4 colon cancer who underwent laparoscopic surgery from January 2008 to December 2014 were enrolled in this study. These patients were divided into the SPS group (n=94) and the MPS group (n=94). The clinical outcomes were compared between groups. Results: The median operative time was significantly shorter in the SPS group than in the MPS group (P=0.045). Postoperative complications did not differ between the groups. The length of postoperative hospital stay was significantly shorter in the SPS group than in the MPS group (P<0.001). Oncological resection rates were similar between groups. The 3-year relapse-free survival rates, the 3-year local recurrence-free survival rates, and the 5-year overall survival rates were similar between groups. Conclusions: SPS is safe and feasible in patients with pathologic T4 colon cancer.
