Abstract

Abstract: Introduction: Single‐incision laparoscopic surgery (SILS) for colon cancer is a recent innovation in minimally invasive surgery that can improve short‐term outcome. However, several biases exist in current favorable comparisons of SILS with conventional laparoscopic (CL) surgery. Moreover, the oncological outcomes in SILS remain unclear. The aim of this study was to identify outcomes following SILS and CL for right colectomy using a propensity score‐matched analysis. Methods: A total of 553 patients underwent curative resection for right colon cancer (58 SILS and 495 CL). After propensity score matching, 58 patients in each group were matched. Results: Before matching, median age was younger ( p = 0.037) and clinical stage was lower ( p < 0.001) in the SILS group. After matching, operation time was shorter (172 versus 193 min, p = 0.007) and blood loss was less (12 versus 20 mL, p = 0.037) in the SILS group. Most of the SILS cases were performed (43.1%) or supervised (51.7%) by an expert surgeon. Median follow‐up duration was 30 and 37 mo in the SILS and CL groups, respectively. Three‐year relapse‐free survival was 92.5% and 92.4% ( p = 0.781); and overall survival was 100% versus 98.1% ( p = 0.177). Conclusions: Under the control of expert surgeons, SILS appeared to be a safe and feasible approach and had similar oncological outcomes compared with CL in a propensity score‐matched cohort of patients with right‐sided colon cancer.
