Purpose Rectosigmoid resection rectopexy has been established as an effective therapy for obstructive defecation syndrome. The addition of the NOSE-technique provides an even less invasive approach avoiding minilaparotomy, but can be technically challenging. Application of a robotic platform has been proposed to facilitate the specimen extraction and fashioning of the intracorporeal anastomosis and has been proven to be effective in left-sided colectomies. Methods After establishing laparoscopic rectosigmoid-resection-rectopexy with NOSE, we modified our technique by addition of the robotic platform. Whenever robotic capacity was available, elective patients scheduled for rectosigmoid resection rectopexy for obstructive defecation syndrome were operated robotically assisted. Demographic and intraoperative data were prospectively collected. Follow up was assessed using the Wexner constipation score, Wexner incontinence score, and Altomare ODS score. Results The NOSE-RRR technique was completed in all 31 patients. The mean operative time was 166 min (range 67–230). No conversion was required. The median hospital stay was 5 days (range 3–28). Four patients had minor complications (Clavien I). Two patients were reoperated (Clavien IIIb). Functional scores improved significantly postoperatively. Mean Wexner incontinence score was 7.1 preoperatively, 6.9 after 1 month, and decreased significantly to 3.93 after 3 months ( p < 0.001). Mean Altomare ODS score was 17.47 preoperatively and 6.93/5.03 after 1/3 months ( p < 0.001). Wexner constipation score (12.83) also showed a significant improvement after 1/3 months (6.97/6.67; p < 0.001). Conclusion NOSE-RRR can be performed safely with a low rate of manageable complications. The technique provides a significant improvement for ODS-Symptoms.
