Summary
Robot-assisted laparoscopic cholecystectomy (RLC) is feasible but takes longer than conventional laparoscopic cholecystectomy (CLC). Trainees performing RLC experienced longer setup and dissection times, indicating slower action execution.
Area of Science:
- Minimally Invasive Surgery
- Surgical Robotics
- Surgical Education
Background:
- Conventional laparoscopic cholecystectomy (CLC) is a standard procedure.
- Robot-assisted laparoscopic cholecystectomy (RLC) offers potential benefits but requires evaluation.
- Surgical trainee performance is crucial for assessing new techniques impartially.
Purpose of the Study:
- To compare the efficacy of CLC and RLC.
- To evaluate surgical trainee performance in both procedures.
- To identify differences in procedure time and actions between CLC and RLC.
Main Methods:
- Two surgical trainees performed 10 CLCs and 10 RLCs using the Zeus-Aesop Surgical Robotic System.
- Primary efficacy parameters included total procedure time and number of actions.
- Secondary parameters assessed setup time, dissection time, and specific action counts (grasping, dissection).
Main Results:
- RLC procedures took significantly longer (123.5 min) than CLC (95.4 min).
- Setup and dissection times were longer for RLC compared to CLC.
- The total number of actions and specific grasping/dissection actions did not differ significantly between the two methods.
Conclusions:
- Robot-assisted laparoscopic cholecystectomy is feasible for surgical trainees.
- RLC requires significantly more time to complete than CLC due to slower action execution.
- Further research may be needed to optimize RLC efficiency for trainees.
