3D virtual reality models help yield better surgical outcomes

September 18, 2019

Los Angeles - A UCLA-led study has found that using three-dimensional virtual reality models to prepare for kidney tumor surgeries resulted in substantial improvements, including shorter operating times, less blood loss during surgery and a shorter stay in the hospital afterward.

Previous studies involving 3D models have largely asked qualitative questions, such as whether the models gave the surgeons more confidence heading into the operations. This is the first randomized study to quantitatively assess whether the technology improves patient outcomes.

The 3D model provides surgeons with a better visualization of a person's anatomy, allowing them to see the depth and contour of the structure, as opposed to viewing a two-dimensional picture.

The study was published in JAMA Network Open.

"Surgeons have long since theorized that using 3D models would result in a better understanding of the patient anatomy, which would improve patient outcomes," said Dr. Joseph Shirk, the study's lead author and a clinical instructor in urology at the David Geffen School of Medicine at UCLA and at the UCLA Jonsson Comprehensive Cancer Center. "But actually seeing evidence of this magnitude, generated by very experienced surgeons from leading medical centers, is an entirely different matter. This tells us that using 3D digital models for cancer surgeries is no longer something we should be considering for the future -- it's something we should be doing now."

In the study, 92 people with kidney tumors at six large teaching hospitals were randomly placed into two groups. Forty-eight were in the control group and 44 were in the intervention group.

For those in the control group, the surgeon prepared for surgery by reviewing the patient's CT or MRI scan only. For those in the intervention group, the surgeon prepared for surgery by reviewing both the CT or MRI scan and the 3D virtual reality model. The 3D models were reviewed by the surgeons from their mobile phones and through a virtual reality headset.

"Visualizing the patient's anatomy in a multicolor 3D format, and particularly in virtual reality, gives the surgeon a much better understanding of key structures and their relationships to each other," Shirk said. "This study was for kidney cancer, but the benefits of using 3D models for surgical planning will translate to many other types of cancer operations, such as prostate, lung, liver and pancreas."

The technology utilized in the study was provided by Ceevra Inc., where Dr. Shirk serves as a consultant.

But in this short, we find out that Beethoven might have made a last-ditch effort to keep his music from ever feeling familiar, to keep pushing his listeners to a kind of psychological limit.
