Background: The efficacy of conventional laparoscopic cholecystectomy (CLC) was compared with robot-assisted laparoscopic cholecystectomy (RLC). Surgical trainees performed the LC to avoid the surgeon’s experience bias. Methods: Two surgical trainees performed 10 CLCs and 10 RLCs at random with a Zeus-Aesop Surgical Robotic System. The primary efficacy parameters were the total time and the number of actions involved in the procedure. The secondary parameters were setup and dissection times, and the number of grasping and dissection actions. Surgical complications were evaluated. Results: For CLC and RLC, respectively, the total times were 95.4 ± 28 min and 123.5 ± 33.3 min and the total actions were 420 ± 176.3 and 363.5 ± 158.2. For CLC, the times required for setup (21 ± 10.4 min) and dissection (50.2 ± 17.7 min) were less than for RLC (33.8 ± 11.3 min and 72 ± 24.3 min, respectively). The numbers of grasping and dissection actions were not significantly different: 41.4 ± 26.5 and 378 ± 173.7, respectively, for CLC versus 48.9 ± 27 and 314.6 ± 141.9, respectively, for RLC. Conclusion: Although feasible, RLC requires significantly more time than CLC because of slower performed actions.
