[3 D laparoscopy versus 2 D laparoscopy : An up to date evaluation].

BACKGROUND: The 3D laparoscopy is currently under intensive discussion. At the moment the majority of newly acquired laparoscopy systems include the 3D technique. New 4K systems, which will be offered in combination with 3D, are complicating the decision-making when buying new laparoscopic systems. The aim of the article is to show the advantages and possible limitations of 3D laparoscopy. Furthermore, the position of 3D laparoscopy in the current video market is evaluated.

MATERIAL AND METHODS: This study was based on an up to date literature search in PubMed. Concerning the question whether the 3D is replacing the 2D laparoscopy, observations from the industry and a personal evaluation were included in the analysis.

RESULTS: The current studies show clear advantages of 3D laparoscopy concerning operation time, efficiency and workload. A major proportion of the studies were conducted on simulation trainers; however, some clinical trials also confirmed these results. The learning curve in laparoscopic surgery is clearly improved with the 3D technique and 3D also seems be useful for operations by experts. The limitation is that not every surgeon can see three dimensionally. Furthermore, the set-up in the operation room needs to be optimized so that a 3D system can be successfully implemented with the nursing staff and side effects, such as exhaustion, dizziness or headache can be prevented.

CONCLUSION: The choice of video system will depend on the personal interest of the surgeon and the ability to see 3D. It can be assumed that the majority of the systems will include 3D laparoscopy but 2D laparoscopy will not be completely replaced. A dynamic development of 3D in association with 4K and robotics can be expected.
