Article Synopsis
- Today's operating rooms are increasingly complex due to the integration of multiple information sources and applications.
- Although manufacturers are making progress, achieving fully integrated operating rooms is still a work in progress.
- Emerging projects show promise, but they currently lack a scalable networking infrastructure, which could be addressed by advancements anticipated with the upcoming 6G standard.
Background: The interest in artificial intelligence (AI) is increasing. Systematic reviews suggest that there are many machine learning algorithms in surgery, however, only a minority of the studies integrate AI applications in clinical workflows. Our objective was to design and evaluate a concept to use different kinds of AI for decision support in oncological liver surgery along the treatment path.

- Image-guided laparoscopic surgery faces challenges when soft-tissue structures deform or move out of view, making it difficult to keep track of them accurately.
- Traditional methods like registration struggle in these dynamic situations, as they rely on continuously updated mappings of the tissues.
- The proposed solution uses a Graph Neural Network to predict the states of these deformed tissues by analyzing stereo laparoscopic videos, allowing for more accurate navigation and understanding in real-time surgical contexts.
Background: Laparoscopic cholecystectomy is a very frequent surgical procedure. However, in an ageing society, less surgical staff will need to perform surgery on patients. Collaborative surgical robots (cobots) could address surgical staff shortages and workload.

- This study looked at how using special laparoscopic tools with vibration feedback can help surgeons learn to handle tissue better.
- They tested three different types of vibrations while experienced surgeons and novices performed tasks like transferring pegs and tying knots.
- The results showed that using the right kind of vibration (F2) helped everyone use less force, especially during tougher tasks like suturing compared to not having any feedback at all.
