Area of Science:

  • Surgical Technology
  • Medical Imaging
  • Augmented Reality in Medicine

Background:

  • Pancreatectomy is a complex surgical procedure requiring high precision.
  • Traditional surgical navigation methods have limitations in visualizing complex anatomy.

Purpose of the Study:

  • To evaluate the effectiveness and utility of augmented reality-based navigation surgery (AR-based NS) for pancreatectomy.
  • To assess the accuracy and visualization capabilities of AR-based NS in pancreatic surgery.

Main Methods:

  • 3D CT image reconstruction and segmentation.
  • Superimposition of 3D images onto the surgical field using an optical location sensor for registration.
  • Assessment of accuracy, visualization, and utility in five pancreatectomy cases.

Main Results:

  • Surface-rendering images closely matched actual organ positions.
  • AR-based NS facilitated safe dissection, preserving adjacent structures.
  • Initial registration error was refined to approximately 5 mm, though challenges in accuracy, portability, and cost persist.

Conclusions:

  • AR-based NS demonstrated significant contributions to accurate and effective surgical resection in pancreatectomy.
  • The pancreas is identified as a suitable organ for further AR-based NS research.
  • This technology holds potential for improving surgical quality, training, and education.
