Proctor-guided virtual reality-enhanced three-dimensional video-assisted thoracic surgery: an excellent tutoring model for lung segmentectomy

A decade of progress: bringing mixed reality image-guided surgery systems in the operating room

Advancements in mixed reality (MR) have led to innovative approaches in image-guided surgery (IGS). In this paper, we provide a comprehensive analysis of the current state of MR in image-guided procedures across various surgical domains. Using the Data Visualization View (DVV) Taxonomy, we analyze the progress made since a 2013 literature review paper on MR IGS systems. In addition to examining the current surgical domains using MR systems, we explore trends in types of MR hardware used, type of data visualized, visualizations of virtual elements, and interaction methods in use. Our analysis also covers the metrics used to evaluate these systems in the operating room (OR), both qualitative and quantitative assessments, and clinical studies that have demonstrated the potential of MR technologies to enhance surgical workflows and outcomes. We also address current challenges and future directions that would further establish the use of MR in IGS.

Virtual Reality to Reduce Pain, Fatigue, and Emotional Distress in People With Cancer: A Scoping Review

BACKGROUND

Cancer and its treatments cause symptoms such as pain, fatigue, and emotional distress, which affect the quality of life of patients at different stages of cancer. Virtual reality (VR) has emerged as a promising alternative for addressing these symptoms by immersing patients in a virtual environment that isolates them from reality.

OBJECTIVE

To describe the existing evidence on the use of VR to improve pain, fatigue, and emotional distress in people with cancer at different stages of the cancer trajectory.

METHODS

A scoping review was conducted following the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) guidelines. Search was conducted in PubMed and CINAHL until October 2023.

RESULTS

Twenty-three primary studies related to the study topic were identified, and the following information was collected: type of VR (immersive vs nonimmersive) used in oncology services, purpose (distraction, training, or relaxation), devices used (head-mounted display, headset, or virtual controller), and the environment simulated (natural environment, skill games, or educational environment). The effects of VR on pain, fatigue, and emotional distress are described, highlighting its ability to mitigate these symptoms in the short term.

CONCLUSIONS

Virtual reality has been shown to be an effective technique for reducing pain, fatigue, and emotional distress in people with cancer in the short term.

IMPLICATIONS FOR PRACTICE

Nurses can use VR as a complementary tool to promote virtual environments that improve the care for and therefore the quality of life of people with cancer.

Tumor Lung Visualization and Localization through Virtual Reality and Thermal Feedback Interface

The World Health Organization estimates that there were around 10 million deaths due to cancer in 2020, and lung cancer was the most common type of cancer, with over 2.2 million new cases and 1.8 million deaths. While there have been advances in the diagnosis and prediction of lung cancer, there is still a need for new, intelligent methods or diagnostic tools to help medical professionals detect the disease. Since it is currently unable to detect at an early stage, speedy detection and identification are crucial because they can increase a patient's chances of survival. This article focuses on developing a new tool for diagnosing lung tumors and providing thermal touch feedback using virtual reality visualization and thermal technology. This tool is intended to help identify and locate tumors and measure the size and temperature of the tumor surface. The tool uses data from CT scans to create a virtual reality visualization of the lung tissue and includes a thermal display incorporated into a haptic device. The tool is also tested by touching virtual tumors in a virtual reality application. On the other hand, thermal feedback could be used as a sensory substitute or adjunct for visual or tactile feedback. The experimental results are evaluated with the performance comparison of different algorithms and demonstrate that the proposed thermal model is effective. The results also show that the tool can estimate the characteristics of tumors accurately and that it has the potential to be used in a virtual reality application to "touch" virtual tumors. In other words, the results support the use of the tool for diagnosing lung tumors and providing thermal touch feedback using virtual reality visualization, force, and thermal technology.

Preoperative Virtual Reality Surgical Rehearsal of Renal Access during Percutaneous Nephrolithotomy: A Pilot Study

Percutaneous Nephrolithotomy (PCNL) is a procedure used to treat kidney stones. In PCNL, a needle punctures the kidney through an incision in a patient’s back and thin tools are threaded through the incision to gain access to kidney stones for removal. Despite being one of the main endoscopic procedures for managing kidney stones, PCNL remains a difficult procedure to learn with a long and steep learning curve. Virtual reality simulation with haptic feedback is emerging as a new method for PCNL training. It offers benefits for both novices and experienced surgeons. In the first case, novices can practice and gain kidney access in a variety of simulation scenarios without offering any risk to patients. In the second case, surgeons can use the simulator for preoperative surgical rehearsal. This paper proposes the first preliminary study of PCNL surgical rehearsal using the Marion Surgical PCNL simulator. Preoperative CT scans of a patient scheduled to undergo PCNL are used in the simulator to create a 3D model of the renal system. An experienced surgeon then planned and practiced the procedure in the simulator before performing the surgery in the operating room. This is the first study involving survival rehearsal using a combination of VR and haptic feedback in PCNL before surgery. Preliminary results confirm that surgical rehearsal using a combination of virtual reality and haptic feedback strongly affects decision making during the procedure.
