Although single-incision laparoscopic surgery (SILS) has gained some attention as a feasible alternative to conventional multiport laparoscopic surgery (MPLS) in colonic surgery, it became less prevalent than expected. Hence, we conducted this systematic review to evaluate the feasibility, safety, and oncological outcomes of single-incision laparoscopic colectomy (SILC) with meta-analysis and discussion of the future prospect of SILS. The search was conducted from September to October 2023 using PubMed and the Cochrane Central Register of Controlled Trials. Articles on colorectal cancer comparing SILC with multiport laparoscopic colectomy (MPLC) from all randomized controlled trials and comparative studies with 50 patients or more per arm were examined. The primary outcomes were the intra- and postoperative complication rates, and the secondary outcomes were the perioperative and oncological outcomes. The trends of the SILS number in Japan and the trends of the number of articles on SILS in PubMed were also reviewed. There were no significant differences in perioperative complication rates, operative factors, and oncological outcomes between SILC and MPLC, although heterogeneity was observed mainly in operative factors and the total length of the skin incision was significantly shorter in SILC. Therefore, SILC is technically and oncologically feasible and safe when performed by experienced laparoscopic surgeons. The case number of SILS was gradually increasing but the rate of SILS was decreasing in Japan. The number of articles on SILS was also decreasing. SILS has gained foothold to some extent but has plateaued. The emerging new robotic platform may reappraise the concept of SILS.
