Right hemicolectomy: laparoscopic versus robotic approach

Abstract

BACKGROUND: Minimally invasive surgery for colorectal cancer has been demonstrated to have the same oncological results as open surgery, with better clinical outcomes. Robotic surgery is an evolution of minimally invasive technique. This study aims to evaluate surgical and oncological short-term outcomes of robotic right colon resection in comparison with the laparoscopic approach.

METHODS: Between January 2014 and May 2017, fifteen laparoscopic right hemicolectomies were compared to seven robotic ones. The primary data points included operation time, length of hospital stay, extraction site incision length, complications, and conversions. When malignancy was the indication for surgery, additional data points have been added.

RESULTS: The study showed no difference in parameters between the two groups, but estimated blood loss was significantly smaller for Robotic arm. We found a prolonged total operative room time in the robotic arm, while the surgical time is similar in two groups. The data collected about specimen length and number of lymph nodes suggest that robotic procedure is oncologically similar to laparoscopic one.

CONCLUSIONS: Robotic approach allows performance of adequate dissection of the right colon with radical lymphadenectomy as in laparoscopic surgery, confirming the safety and oncological efficacy of this technique, with acceptable results and short-term outcomes.
