Surgery for Rectal Cancer With Mixed Reality of 3D Model During Operation: A Case Report

Rie Hayashi et al. Cancer Diagn Progn. .

Abstract

Background/aim: Recently, robotic surgery for rectal cancer has become a common minimally invasive surgery. In addition, the technology of augmented and mixed reality is applied in various living environments, including medicine. We successfully performed robotic surgery for rectal cancer with three-dimensional (3D) images as mixed reality (MR) using HoloLens2.

Case report: The patient was diagnosed with rectal cancer by colonoscopy and a positron-emission computed-tomography scan, and we performed robot-assisted anterior resection. The operator used HoloLens2 and performed the surgery while visualizing 3D images of pelvic anatomy with the location of the rectal cancer as hologram. The operation was performed completely and safely, and she was discharged 11 days after surgery with no postoperative complications.

Conclusion: This case presents the usefulness of a MR system offering organ visualization as hologram during surgery.

Keywords: Rectal cancer; holograms; mixed reality; robotic surgery.
