Since the da Vinci SP (dVSP) surgical system was introduced, single-incision robotic surgery (SIRS) for colorectal diseases has gained increasing acceptance. Comparison of the short-term outcomes between SIRS using dVSP and those of conventional multiport laparoscopic surgery (CMLS) was performed to verify its efficacy and safety in colon cancer. The medical records of 237 patients who underwent curative resection for colon cancer by a single surgeon were retrospectively reviewed. Patients were divided into two groups according to surgical modality: SIRS (RS group) and CMLS (LS group). Intra- and postoperative outcomes were analyzed. Of the 237 patients, 140 were included in the analysis. Patients in the RS group (n = 43) were predominantly female, younger, and had better general performance than those in the LS group (n = 97). The total operation time was longer in the RS group than in the LS group (232.8 ± 46.0 vs. 204.1 ± 41.7 min, P < 0.001). The RS group showed faster first flatus passing (2.5 ± 0.9 vs. 3.1 ± 1.2 days, P = 0.003) and less opioid analgesic requirement (analgesic withdrawal within 3 postoperative days: 37.2% vs. 18.6%, P = 0.018) than the LS group. The RS group showed a higher immediate postoperative albumin level (3.9 ± 0.3 vs. 3.6 ± 0.4 g/dL, P < 0.001) and lower C-reactive protein level (6.6 ± 5.2 vs. 9.3 ± 5.5 mg/dL, P = 0.007) than the LS group during the postoperative period. On multivariate analysis after adjusting for deviated patient characteristics, no significant difference was observed in short-term outcomes, except for operation time. SIRS with dVSP showed short-term outcomes comparable with those of CMLS for colon cancer. © 2023, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.
