Clinical Study of Robotic Natural Orifice Specimen Extraction Surgery for Right Colon Cancer
Abstract
Objective
To evaluate the safety and feasibility of robotic natural orifice specimen extraction surgery (NOSES) for right colon cancer.
Methods
Twenty-two female patients undergoing this procedure between January 1, 2022 and January 31, 2025 were enrolled. Safety and feasibility were assessed by analyzing operative time, intraoperative blood loss, conversion rate to open surgery, postoperative complications, 30-day mortality, and 30-day unplanned surgery-related readmission rate.
Results
All procedures were completed successfully. The median operative time was 158 min (152-169 min), and the median blood loss was 53 mL (43-75 mL). No conversions to open surgery occurred. The first postoperative flatus occurred at a median of 53.00 h (49.25-57.50 h), and the median postoperative hospital stay was 9.00 d (8.00-11.00 d). Postoperative complications included one case of intestinal obstruction. No anastomotic leakage, anastomotic bleeding, vaginal hemorrhage, vaginal infection, or abdominal infection was observed. There were no deaths within 30 days and no unplanned surgery-related readmissions.
Conclusion
Robotic NOSES for right colon cancer is safe and feasible.
