WCE 2018: 3D Laparoscopy

Paris, France (UroToday.com) Laparoscopic surgery is one of the most significant surgical milestones of the 20th century. Due to laparoscopy’s clinical and surgical benefits over open surgery, it is the preferred choice for many surgeons. Since laparoscopy’s inception, however, challenges with the technology have been identified. Laparoscopy’s limited range of motion, poor perception of depth with 2D imaging systems, and longer learning curve have begun to inspire improvements within the field of laparoscopic surgery.

One of these innovations, Dr. Kaouk describes, is 3D laparoscopy. 3D Laparoscopy combats some of the limitations of traditional laparoscopy by introducing two side-by-side (stereoscopic) cameras to the laparoscope (Figure 1).

Each camera creates its own respective image and relays this image to one of the lenses of an eyepiece. Dr. Kaouk mentioned that due to the cumbersome nature of eyeglasses during an operation (i.e. fogging, uncomfortable weight), 3D head-mounted displays are more frequently used to visualize the 3D laparoscopic images.

Although this technology is promising, Dr. Kaouk indicated that there has been no definitive proof that 3D laparoscopy improves surgical outcomes. Some studies have done systematic reviews and shown minor benefits to 3D laparoscopy, but a more comprehensive analysis is still needed to put this technology at the forefront of clinical practice. Furthermore, Dr. Kaouk indicates that robotic technology is the most widespread form of 3D laparoscopy, and more developments are needed for 3D laparoscopy to compete with 3D robotic vision.
