Live surgical demonstrations for minimally invasive colorectal surgery may increase operative risks. Patients in live demonstration settings experienced longer operating times, more blood loss, and higher overall complication rates compared to routine practice.
Area of Science:
- Colorectal Surgery
- Surgical Education
- Minimally Invasive Surgery
Background:
- Live surgical demonstrations are valuable educational tools for surgical trainees.
- They offer insights into expert surgeons' real-time decision-making.
- Impact on minimally invasive colorectal surgery outcomes remains unevaluated.
Purpose of the Study:
- To evaluate perioperative and short-term postoperative outcomes.
- To compare outcomes of minimally invasive colorectal surgery performed as live demonstrations versus routine practice.
Main Methods:
- Case-matched study comparing live demonstration cases (study group) with routine practice cases (control group).
- Data collected from 2006 to 2018.
- Comparison focused on intraoperative and short-term postoperative outcomes.
Main Results:
- Live surgery group had longer operating times (200 vs. 165 min) and higher blood loss (100 vs. 55 ml).
- Hospital stay was longer in the live surgery group (6 vs. 5 days).
- Overall complications were significantly higher in the live surgery group (22 vs. 9), with one reoperation and one mortality.
Conclusions:
- Live surgical demonstrations in minimally invasive colorectal surgery are associated with increased operative morbidity.
- Potential risks include longer operating times, increased blood loss, and higher complication rates.
- Further research may be needed to mitigate risks associated with live surgical education.
