Abstract
Purpose
The da Vinci single-port (SP) system has been used in various surgical fields, including colorectal surgery. However, limited experience has been reported on its safety and feasibility. This study aims to evaluate the short-term outcomes of SP robotic surgery for the treatment of rectal cancer compared with multiport (MP) robotic surgery.
Methods
Rectal cancer patients who underwent curative resection in 2020 were reviewed. A total of 43 patients underwent robotic total mesorectal excision (TME), of which 26 (13 in each group, SPTME vs. MPTME) were included in the case-matched cohort for analysis. Intraoperative and postoperative outcomes and pathological results were compared between the 2 groups.
Results
Median tumor height was similar between the 2 groups (SPTME vs. MPTME: 5.9 cm [range, 2.2-9.6 cm] vs. 6.7 cm [range, 3.4-10.0 cm], P = 0.578). Preoperative chemoradiotherapy was equally performed (38.5%). The median estimated blood loss was less (20.0 mL [range, 5.0-20.0 mL] vs. 30.0 mL [range, 20.0-30.0 mL], P = 0.020) and the median hospital stay was shorter (7 days [range, 6-8 days] vs. 8 days [range, 7-9 days], P = 0.055) in the SPTME group. Postoperative complications did not differ (SPTME vs. MPTME: 7.7% vs. 23.1%, P = 0.587). One patient in the SPTME group and 3 in the MPTME group experienced anastomotic leakage.
Conclusion
SP robotic TME showed perioperative outcomes similar to MP robotic TME. The SP robotic system can be considered a surgical option for the treatment of rectal cancer. Further prospective randomized trials with larger cohorts are required.
