Summary
Mixed-reality (MR) technology offers 3D holographic surgical navigation. While feasible for laparoscopic cholecystectomy, its efficacy with 3D models may depend on surgeon experience.
Area of Science:
- Surgical Technology
- Medical Imaging
- Minimally Invasive Surgery
Background:
- Mixed-reality (MR) technology presents 3D holographic images in surgical settings via wearable devices.
- This technology aims to enhance surgical visualization and navigation.
Purpose of the Study:
- To evaluate the safety and efficacy of using a holography-guided navigation system for laparoscopic cholecystectomy.
- To compare surgical outcomes between MR-guided 3D models and conventional 2D imaging.
Main Methods:
- A prospective observational study involving 27 patients undergoing laparoscopic cholecystectomy.
- Nine patients received 3D model navigation via MR devices; 18 used conventional 2D images.
- Surgical outcomes (operative time, blood loss, complications) and subjective surgeon feedback were assessed.
Main Results:
- Median operative time was longer with 3D models (74.0 min) compared to 2D images (58.0 min).
- No intraoperative blood loss or perioperative complications were reported in either group.
- Surgeon experience influenced the perceived difficulty of using 3D models.
Conclusions:
- Laparoscopic cholecystectomy using 3D models via MR technology is feasible.
- The effectiveness of this advanced navigation system may be influenced by the surgeon's level of experience.
