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.
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.
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.
Although feasible, RLC requires significantly more time than CLC because of slower performed actions.
比较了传统腹腔镜胆囊切除术（CLC）与机器人辅助腹腔镜胆囊切除术（RLC）的疗效。由外科住院医师进行LC手术，以避免外科医生的经验偏差。
两名外科住院医师使用宙斯-伊索手术机器人系统随机进行10例CLC和10例RLC手术。主要疗效参数为手术总时间和手术中涉及的动作数量。次要参数为设置和解剖时间，以及抓取和解剖动作的数量。评估手术并发症。
CLC和RLC的总时间分别为95.4±28分钟和123.5±33.3分钟，总动作分别为420±176.3次和363.5±158.2次。对于CLC，设置（21±10.4分钟）和解剖（50.2±17.7分钟）所需时间少于RLC（分别为33.8±11.3分钟和72±24.3分钟）。抓取和解剖动作的数量无显著差异：CLC分别为41.4±26.5次和378±173.7次，RLC分别为48.9±27次和314.6±141.9次。
尽管RLC可行，但由于动作执行较慢，其所需时间比CLC显著更多。
