Robotic sphincter saving rectal cancer surgery: A learning curve analysis
1Department of General Surgery, Acibadem Mehmet Ali Aydinlar University School of Medicine, Istanbul, Turkey.
Summary
Robotic rectal surgery operative times improve after an initial learning curve, showing reduced blood loss and better surgical outcomes. A laparoscopically experienced surgeon may need more cases than previously reported to master robotic techniques.
Area of Science:
- Surgical Oncology
- Robotic Surgery
- Medical Education
Background:
- Longer operative times are a key challenge in robotic rectal surgery.
- Improving surgical efficiency is crucial for realizing the benefits of robotic procedures.
Purpose of the Study:
- To evaluate the learning curve for robotic surgery in sphincter-preserving rectal cancer operations.
- To identify the number of cases required for a surgeon to achieve proficiency.
Main Methods:
- The cumulative sum (CUSUM) method was used to assess the learning curve.
- Operative time was the primary variable analyzed for learning curve calculation.
Main Results:
- The learning curve was divided into two phases, with phase 2 involving 44 operations.
- Phase 2 demonstrated significantly shorter operative times (323.3 min vs. 379.9 min), reduced blood loss (37.2 mL vs. 87.7 mL), longer distal resection margins (4.5 cm vs. 2.5 cm), and improved mesorectal completeness compared to phase 1.
Conclusions:
- The learning curve for robotic rectal surgery may extend beyond previously reported case numbers for experienced laparoscopic surgeons.
- Achieving proficiency in robotic rectal surgery requires a substantial number of procedures to optimize outcomes.
