Summary
Three-dimensional simulation analysis (SA) is a valuable tool for planning liver segmentectomies. This technology accurately maps liver anatomy, aiding surgeons in precise resection and improving surgical outcomes.
Area of Science:
- Hepatobiliary Surgery
- Surgical Planning
- Medical Imaging
Background:
- Anatomic liver segmentectomy and subsegmentectomy are complex surgical procedures.
- Accurate pre-operative planning is crucial for successful outcomes.
Purpose of the Study:
- To assess the applicability and utility of 3D simulation software for anatomic liver segmentectomy and subsegmentectomy.
Main Methods:
- Prospective study of 83 patients undergoing anatomic segmentectomy or subsegmentectomy.
- Preoperative 3D simulation analysis (SA) was performed for operative planning.
- Evaluation of clinical information from 3D SA and consistency between virtual and real hepatectomy.
Main Results:
- 3D SA took an average of 18.3 minutes to complete.
- 3D SA identified multi-segment resections in 35% of patients and aided in defining resection lines in 31%.
- Calculated volumes strongly correlated with resected specimens (R(2) = .9942), and hepatic veins were clearly visualized in 86% of cases.
Conclusions:
- 3D SA provides accurate pre-operative planning for liver surgery.
- The software assists surgeons in planning and executing anatomic segmentectomies and subsegmentectomies effectively.
