This study was designed to compare conventional laparoscopy with three-dimensional (3-D) laparoscopy.
Thirty candidates, 20 inexperienced and 10 experienced in operative laparoscopy, executed standardized exercises on a pelvitrainer. The candidates were randomized to two groups. Group A executed the exercises first with the conventional and then with the three-dimensional system. Group B accomplished the exercises in the reverse sequence. At the end of the exercises, the candidates answered specific questions about the two systems.
A total of 21 h 6 min 6 sec of laparoscopic exercises were analyzed-10 h 8 min 1 sec with the conventional and 10 h 58 min 5 sec with the three-dimensional system (p = 0.38). Group A required 12 h 26 min 56 sec to perform all the exercises. There was no statistically significant difference from group B, where the candidates needed 8 h 39 min 10 sec (p = 0.14). Neither were there any differences in the number of failed attempts between the two groups. There were also no statistical difference when the results obtained from the candidates without experience in laparoscopy and the participants experienced in operative laparoscopy were analyzed separately. Both the inexperienced and the experienced candidates became tired earlier, had more headaches, and needed extra time to adapt to the 3-D system.
When analyzed in a standardized fashion, 3-D laparoscopy does not have any significant advantages over conventional laparoscopy.
本研究旨在比较传统腹腔镜检查与三维（3-D）腹腔镜检查。
30名受试者，其中20名无腹腔镜手术经验，10名有腹腔镜手术经验，在盆腔训练器上进行标准化练习。受试者被随机分为两组。A组先使用传统系统后使用三维系统进行练习。B组按相反顺序完成练习。练习结束时，受试者回答关于这两种系统的特定问题。
共分析了21小时6分6秒的腹腔镜练习——使用传统系统为10小时8分1秒，使用三维系统为10小时58分5秒（p = 0.38）。A组完成所有练习需要12小时26分56秒。与B组相比无统计学显著差异，B组受试者需要8小时39分10秒（p = 0.14）。两组之间失败尝试的次数也无差异。分别分析无腹腔镜手术经验的受试者和有腹腔镜手术经验的参与者的结果时也无统计学差异。无经验和有经验的受试者都更早感到疲劳，头痛更多，并且需要额外时间来适应三维系统。
以标准化方式分析时，三维腹腔镜检查与传统腹腔镜检查相比没有任何显著优势。
