[Background] Although laparoscopic surgery is a widely used procedure, two-dimensional laparoscopy(2D) may cause loss of depth perception for surgeons. To solve this problem, three-dimensional laparoscopy(3D) has been developed. [Objective] The aim of this study is to evaluate whether 3D provides greater benefit in surgical performance and subjective experience than 2D when used for suturing of the peritoneum in a simulated setting for laparoscopic hernia repair. [Methods] Twelve physicians participated in the study and performed suturing following a template in a box inguinal trainer using both 2D and 3D laparoscopes. Total performance time and number of errors were measured as objective parameters by analyzing the recorded video. Subjective evaluation using a questionnaire was also performed. [Results] The time taken for the task using 3D was significantly shorter than the time for 2D(3D : 943 seconds, 2D : 1,365 seconds, p<0.01). The number of errors was significantly less when 3D was used compared to 2D(3D : 6, 2D :33, p<0.01). In the post-study questionnaire, all participants preferred 3D to 2D(p<0.01). [Conclusion] Our results suggest that the 3D will be helpful for surgeons to perform intracorporeal suturing. The impact of 3D laparoscopy on clinical outcomes is yet to be examined.
