Introduction: Robotic surgery remains a novel technique in the field of colorectal surgery in Japan. Several small series have examined its safety and feasibility for colorectal surgery. Our aim was to analyze our entire experience and short-term outcomes with robotic surgery for rectal cancer since its introduction at the former and the present institution. We assert that this approach is feasible and safe for the patients with rectal cancer.
Material and Methods: This is a retrospective analysis of prospectively gathered data for all patients who underwent robotic surgery for rectal cancer with the use of single docking technique of Da Vinci S or Si system between November 2012 and September 2017. Clinical, operative and pathologic factors were reviewed and analyzed.
Results: Seventy patients underwent robotic surgery for rectal cancer during the study period. The locations of tumor were 26 upper rectum, 44 lower rectum. The procedure were as follow, high anterior resection in 6, low anterior resection in 51, ISR in 6, APR in 7 patients. Eight patients underwent bilateral lymph nodes dissection (LLND). The procedures were performed successfully in all cases. Mean age was 66.5 years, and 70% of the patients were men, and the mean body mass index was 22.5( range, 18.5-29.4) kg/m2. Median operative duration was 321(190-666)minutes. Median blood loss was 15(0-270)ml. Median postoperative stay was 13 (6-16) days. Mean harvest lymph node number was 17.0 (5-37). Surgical margins were negative in all cases. There was one conversion due to bleeding during the LLND and anastomotic leakage occurred in two patients. Morbidity was 17%. There was no mortality postoperatively in this series.
Conclusion: In early series of the selected patients, this technique appears to be fesible and safe when performed by surgeons skilled in laparoscopic colorectal surgery. These findings support the use of a robotic approach for patients requiring rectal surgery.
