Introduction:
The popularity of robotic surgery highlights the need for strategies to integrate this technique into surgical education. We present 5 year data for robotic cholecystectomy (RC) as a model for training residents.
Methods:
Data were collected on all RC over 66 months. Duration for docking the robot (S2) and performing RC (S3), and surgical outcomes, were recorded. We used a linear mixed effects model to investigate learning curves.
Results:
Thirty-eight trainees performed 160 RCs, with most performing more than four. One case was aborted due to haemodynamic instability, and two were converted to open surgery due to adhesions. There were no technical complications. The duration of S2 (mean = 6.2 ± 3.6 min) decreased considerably (p = 0.027). Trainees also demonstrated decrease in duration of S3 (mean = 38.4 ± 15.4 min), indicating improvement in technique (p = 0.008).
Conclusions:
RC is an effective model for teaching residents. Significant and reproducible improvement can be realized with low risk of adverse outcomes.
