Summary
This study evaluated the Resection Map, a 3D visualization tool for liver resection surgery. Surgeons reported improved orientation and confidence, aiding in safer hepatectomy procedures.
Area of Science:
- Surgical Navigation Systems
- Medical Imaging
- Hepatic Surgery
Background:
- Evaluating a novel intraoperative 3D visualization system for hepatectomy.
- The Resection Map provides surgeons with accurate cartography to anticipate risks and enhance safety.
Purpose of the Study:
- To assess the utility of the Resection Map in supporting hepatectomy procedures.
- To improve surgeon confidence and orientation during liver resections.
Main Methods:
- Prospective cohort study of ten patients undergoing hepatectomy.
- Segmentation of liver structures from CT scans for pre-operative planning.
- Surgeons used the Resection Map as intraoperative guidance.
Main Results:
- The Resection Map was used by three surgeons on seven patients.
- Displayed veins were identified in 70.1% of cases, with identification correlating with size.
- Surgeons experienced improved orientation and increased confidence during procedures.
Conclusions:
- The Resection Map offers a practical method to enhance surgeon orientation and confidence.
- Further research is required to confirm improvements in patient safety.
