- Purpose
Robot-assisted surgery is readily applied to every type of colorectal surgeries. However, studies showing the safety and feasibility of robotic surgery (RS) have dealt with rectal cancer more than colon cancer. This study aimed to investigate how technical advantages of RS can translate into actual clinical outcomes that represent postoperative systemic response.
Methods
This study retrospectively reviewed consecutive cases in a single tertiary medical center in Korea. Patients with primary colon cancer who underwent curative resection between 2006 and 2012 were included. Propensity score matching was done to adjust baseline patient characteristics (age, sex, body mass index, American Society of Anesthesiologists physical status, tumor profile, pathologic stage, operating surgeon, surgery extent) between open surgery (OS), laparoscopic surgery (LS), and RS groups.
Results
After propensity score matching, there were 66 patients in each group for analysis, and there was no significant differences in baseline patient characteristics. Maximal postoperative leukocyte count was lowest in the RS group and highest in the OS group (P=0.021). Similar results were observed for postoperative neutrophil count (P=0.024). Postoperative prognostic nutritional index was highest in the RS group and lowest in the OS group (P<0.001). The time taken to first flatus and soft diet resumption was longest in the OS group and shortest in the RS group (P=0.001 and P<0.001, respectively). Among all groups, other short-term postoperative outcomes such as hospital stay and complications did not show significant difference, and oncological survival results were similar.
Conclusion
Better postoperative inflammatory indices in the RS group may correlate with their faster recovery of bowel motility and diet resumption compared to LS and OS groups.

Abstract

Supplementary Material
- Tumors at the level of the anorectal junction had required abdominoperineal resection (APR) to achieve an adequate resection margin. However, in the cases of tumor invading ipsilateral levator-ani muscle (LAM), en-bloc resection of the rectum with LAM including tumor would be possible. This video is to show the critical anatomic steps of this procedure. A video was produced from the robotic right partial excision of LAM (PELM) performed in a 57-year-old female patient with rectal cancer at 3 cm from the anal verge, invading the ipsilateral anorectal ring, who had received neoadjuvant chemoradiotherapy. The patient discharged at postoperative day 8 without complication. The pathology of the surgical specimen revealed ypT3N1bM0. The secure resection margin from the tumor was achieved. Robotic PELM is the sphincter-preserving technique that can be an alternative treatment option for low rectal cancer invading the ipsilateral LAM, which has been an indication for APR or extralevator APR.
