Robotic versus laparoscopic left colectomy: a propensity score matched analysis from a bi-centric experience

Area of Science:

• Colorectal Surgery
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• The benefits of robotic platforms in left colectomies are not well-established due to limited evidence.
• Conflicting outcomes exist regarding robotic left colectomies (RLC).

Purpose of the Study:

• To evaluate the role of robotic approach in left colectomy by reporting a bi-centric experience.
• To compare safety and efficacy of RLC versus laparoscopic left colectomy (LLC).

Main Methods:

• A bi-centric propensity score-matched study comparing RLC and LLC.
• Included patients who underwent RLC or LLC between January 1, 2012, and May 1, 2022.
• Matched RLC and LLC patients in a 1:1 ratio, focusing on conversion to open surgery and 30-day morbidity.

Main Results:

• No significant differences in conversion rates (4.2% vs. 7.6%), 30-day morbidity (16.1% vs. 13.7%), severe complications, transfusions, or mortality between RLC and LLC.
• Robotic left colectomy had a significantly longer median operative time (296 min vs. 245 min).
• Early oral feeding, time to first flatus, and hospital stay were similar between the two groups.

Conclusions:

• Robotic left colectomy demonstrates comparable safety and conversion rates to standard laparoscopy.
• The robotic approach for left colectomy is associated with a longer operative time but similar patient recovery outcomes.
