Summary
Mixed Reality (MR) integration in right hemicolectomy (RHC) for colon cancer improved patient outcomes. MR enhanced surgical precision, reducing blood loss and hospital stays while increasing lymph node yield.
Area of Science:
- Surgical Oncology
- Medical Technology
- Gastrointestinal Surgery
Background:
- Right hemicolectomy (RHC) is a key treatment for colorectal cancer.
- Vascular variations in the superior mesenteric artery and vein present surgical challenges.
- Integrating advanced technology can potentially improve surgical outcomes.
Purpose of the Study:
- To evaluate the short-term outcomes of using Mixed Reality (MR) in RHC for colon cancer.
- To assess the impact of MR on surgical precision, patient recovery, and educational value.
Main Methods:
- Retrospective study of patients undergoing RHC for stage II or III colon cancer (Jan 2015 - Aug 2024).
- Comparison between MR (+) group (n=47) and MR (-) group (n=145).
- Propensity score matching used to create comparable groups (n=44 per group).
- MR utilized SYNAPSE VINCENT, Holoeyes MD, and HoloLens2 for 3D vascular visualization.
Main Results:
- The MR (+) group showed decreased intraoperative blood loss and shorter hospital stays compared to the MR (-) group.
- Increased number of harvested lymph nodes around the middle colic artery/vein in the MR (+) group.
- Operative time was not prolonged in the MR (+) group.
Conclusions:
- Mixed Reality integration in RHC enhances surgical precision and safety.
- MR technology facilitates improved patient recovery and offers significant educational benefits.
- MR is a valuable tool for optimizing RHC procedures in colon cancer treatment.
