Short-term Outcomes of Single-port Versus Multiport Laparoscopic Surgery for Colon Cancer: The SIMPLE Multicenter Randomized Clinical Trial

Objective: To compare short-term perioperative outcomes of single-port laparoscopic surgery (SPLS) and multiport laparoscopic surgery (MPLS) for colon cancer. Summary Background Data: Although many studies reported short- and long-term outcomes of SPLS for colon cancer compared with MPLS, few have reported results of randomized controlled trials. Methods: This was a multicenter, prospective, randomized controlled trial with a noninferiority design. It was conducted between August 2011 and June 2017 at 7 sites in Korea. A total of 388 adults (aged 19–85 yrs) with clinical stage I, II, or III adenocarcinoma of the ascending or sigmoid colon were enrolled and randomized. The primary endpoint was 30-day postoperative complication rates. Secondary endpoints were the number of harvested lymph nodes, length of the resection margin, postoperative pain, and time to functional recovery (bowel movement and diet). Patients were followed for 30 days after surgery. Results: Among 388 patients, 359 (92.5%) completed the study (SPLS, n = 179; MPLS, n = 180). The 30-day postoperative complication rate was 10.6% in the SPLS group and 13.9% in the MPLS group (95% confidence interval, −10.05 to 3.05 percentage points; P
