Summary
Robotic colorectal surgery start time does not impact patient outcomes. This study found no correlation between morning versus afternoon procedures and complications, suggesting experienced teams and surgical ergonomics mitigate previous findings.
Area of Science:
- Surgical Outcomes
- Robotic Surgery
- Colorectal Surgery
Background:
- Previous studies indicated higher complication rates in afternoon surgeries.
- The impact of surgery start time on robotic surgery outcomes requires investigation.
Purpose of the Study:
- To evaluate if morning versus afternoon start times affect robotic colorectal surgery outcomes.
- To compare preoperative risk factors, intraoperative events, and 30-day postoperative outcomes between morning and afternoon robotic colorectal surgeries.
Main Methods:
- Retrospective review of a prospective database including 210 robotic colorectal surgeries.
- Comparison of 97 morning cases versus 113 afternoon cases.
- Statistical analysis using independent samples t-test, Fisher's exact test, and linear regression.
Main Results:
- Morning patients were younger but had similar BMI, comorbidity scores, operative time, and blood loss compared to afternoon patients.
- Morning surgeries resulted in a shorter length of stay (6.0 vs. 8.0 days).
- No significant differences were observed in overall postoperative complications, wound infections, anastomotic leaks, ileus, or 30-day readmissions between morning and afternoon procedures.
Conclusions:
- No correlation was found between robotic colorectal surgery start time and intra- or postoperative outcomes.
- Experienced surgical teams, high-volume centers, and superior robotic surgery ergonomics may explain the lack of difference.
- These factors may mitigate previously reported negative impacts of afternoon surgery start times.
