title: [Skills comparison using a 2D vs. 3D laparoscopic simulator].
abstract: BACKGROUND
  The development and application of 3D images in laparoscopic surgery has brought the benefit of in-depth perception that traditional laparoscopic surgery lacked. Previous studies in surgical populations have demonstrated the advantages of 3D technology. To limit bias of the previous experiences of participants, this study was performed in a population without any experience in this area.
  
  
  METHODS
  An experimental, open, cross-sectional, comparative study between surgical skills achievements using 2D and a 3D laparoscopy equipment, using each subject as their own control. Six skills were evaluated in 2D and 3D modalities.
  
  
  RESULTS
  Of the 40 participants included, 20 began the skills in the 2D modality and then performed them in 3D, and the other 20 began in 3D. Of the 118 skills evaluated there was a time improvement in 72% in the 3D group compared to 37% in the 2D modality (P=.000). The accomplishment percentage using the 3D laparoscopy was greater for both groups. There was a statistically significant difference in the better time for the 3D performed tasks. Just over half (52.5%) of participants preferred 3D laparoscopy, 15% preferred 2D, and 32.5% had no preferences.
  
  
  CONCLUSIONS
  As other studies have demonstrated, there was improvement in the overall performance using the 3D laparoscope. Bias was limited by using a population without surgical experience.
  
  
  CONCLUSIONS
  3D laparoscopic surgical skills showed superior to 2D, with higher percentages of tasks completion, less time in performing them, and a shorter learning curve.
