The main drawbacks of conventional 2D laparoscopy are limited depth perception and loss of spatial orientation. High-quality 3D laparoscopy systems might improve surgical outcomes for adrenalectomy.


Over recent decades, technological advances such as improved video imaging (high-definition cameras), better instrumentation for dissection and hemostasis, articulating staplers, and optimized operating room lighting have added safety, efficacy, and precision to minimally invasive procedures. However, until recently, laparoscopy required surgeons to operate in a three-dimensional (3D) space with only two-dimensional (2D) images to guide their movements, resulting in a lack of depth perception and loss of spatial orientation that increased the risk of errors, fatigue, operative time, and operating room stress and made the technique difficult to learn.

High-quality 3D laparoscopy was developed as an alternative to conventional 2D laparoscopy. Several clinical trials and observational studies have compared surgical outcomes between 2D and 3D laparoscopic systems; however, few clinical studies have examined the usefulness of 3D laparoscopy systems for adrenalectomies.
