Summary
Robot-assisted colorectal surgery shows similar short-term patient outcomes to laparoscopic surgery. Length of stay and 30-day readmission rates were comparable between robotic and laparoscopic approaches for rectal resections.
Area of Science:
- Colorectal surgery
- Minimally invasive surgery
- Robotic surgery
Background:
- Robot-assisted colorectal surgery is increasingly popular.
- Patient-related benefits compared to laparoscopic surgery remain unclear.
Purpose of the Study:
- To compare short-term patient outcomes between robotic and laparoscopic rectal resections.
Main Methods:
- Retrospective cohort study at 5 tertiary care centers.
- 863 patients undergoing robotic or laparoscopic partial/complete rectal resections (Jan 2010-Dec 2019).
- Outcomes assessed: length of stay, ED returns, 30-day readmissions, mortality.
Main Results:
- 458 robotic vs. 405 laparoscopic procedures.
- Robotic group had more male, obese, and overweight patients.
- No significant differences in ED returns, length of stay, 30-day readmissions, or mortality between groups after adjusting for comorbidities.
Conclusions:
- Length of stay and 30-day readmission rates were similar for robotic and laparoscopic rectal surgery.
- Male patients and those with higher BMI were more likely to receive robotic surgery.
- Study limitations include lack of randomization and potential surgeon learning curve.
