Comparison of 3D imaging and 2D imaging for performance time of laparoscopic cholecystectomy.

Objective: The aim of this study is to evaluate the effect of the Viking 3-dimensional (3D) system on performance time of laparoscopic cholecystectomy.

Methods: Twenty-two patients were included in the study. The groups were standardized using a multiparameters filter (MPF) depending on preoperative ultrasonography and perioperative exploration findings. The 11 patients operated with the Viking 3D system (group A) were compared with 11 patients operated with the Olympus 2D/HD system (group B).

Results: The mean performance time was 20.63 ± 5.66 and 30.0 ± 6.03 minutes in the group A (3D) and group B (2D), respectively (P<0.01).

Conclusions: The 3D imaging systems may cause a significant reduction in the performance time of laparoscopic cholecystectomy.
