摘要

Background

Single-incision robotic surgery (SIRS) using the da Vinci SP system (dVSP) offers advantages such as improved cosmesis, reduced invasiveness, and technical precision in colorectal surgery. However, real-world data regarding the technical feasibility and oncologic outcomes of dVSP-based complete mesocolic excision (CME) with central vascular ligation (CVL) for right-sided colon neoplasms remain limited.

Methods

We retrospectively reviewed the medical records of patients who underwent single-incision robotic right colectomy for colon cancer or precancerous lesions with dVSP between July 2019 and April 2025. Demographic characteristics, perioperative outcomes, pathologic results, and survival outcomes were analyzed.

Results

Fifty-two patients were included. Mean operation time and estimated blood loss were 282.2 ± 54.5 min and 65.9 ± 44.9 ml, respectively. Intracorporeal anastomosis was performed in 67.3% of cases, and the mean umbilical wound length was 3.7 ± 0.9 cm. There were no conversions to open surgery or intraoperative complications. The mean time to first flatus was 2.6 ± 0.7 days, and patients began a soft diet at 3.2 ± 0.6 days postoperatively, with a mean hospital stay of 7.0 ± 2.4 days. Postoperative complications occurred in 19.2% and readmission rate was 5.8%. Pathologic outcomes showed 23.9% of patients with stage III disease, the mean number of harvested lymph nodes was 45.5 ± 25.0, and all cases had negative resection margins. One patient (1.9%) developed local recurrence at 8 months postoperatively, resulting in disease-specific mortality, and another patient (1.9%) developed multiple lung metastases at 9 months and is currently receiving palliative chemotherapy. Among patients with malignant tumors, 5-year overall survival and disease-free survival rates were 93.3% and 93.7%, respectively. The median follow-up period was 30.0 (range 5.0–72.0) months.

Conclusion

Single-incision robotic right colectomy using the dVSP is technically feasible and safe approach, offering favorable perioperative results and has proven oncologic safety based on long-term outcomes.
