Abstract:
Although meta-analyses and systematic reviews have clarified the benefits of robotic surgery, few studies have focused on robotic rectal surgery (RRS) and the use of Endowrist® instruments. Therefore, we evaluated RRS using the double bipolar method (DBM) and compared its short-term outcomes with those of RRS using the single bipolar method (SBM). This study enrolled 157 consecutive patients and all procedures were performed by the same surgeon and recorded through short video clips. We analyzed the patient demographics and short-term clinical outcomes. Although this observational study has several limitations, the console time for total mesorectal excision using the DBM was significantly shorter than that using the SBM. Although the DBM did not demonstrate a specific learning curve, it was a safe and feasible procedure even for patients with advanced disease. Further studies are needed to evaluate the cost-effectiveness of the DBM.
