Summary
Protective hepatectomy using 3D reconstruction aids in treating hepatolithiasis by enabling precise surgery. This technique ensures efficient calculus removal while preserving functional liver tissue and minimizing complications.
Area of Science:
- Hepatobiliary Surgery
- Medical Imaging
- Surgical Planning
Background:
- Hepatolithiasis poses significant treatment challenges.
- Traditional surgical approaches may risk damage to functional liver tissue.
- Advanced imaging techniques can improve surgical precision.
Purpose of the Study:
- To evaluate the efficacy of protective hepatectomy guided by 3D reconstruction for hepatolithiasis treatment.
- To assess the safety and outcomes of this minimally invasive approach.
Main Methods:
- 21 patients with hepatolithiasis underwent CT scans for 3D reconstruction.
- Preoperative surgical simulation using 3D models guided protective hepatectomy.
- Outcomes including operating time, hospital stay, blood loss, and complication rates were recorded.
Main Results:
- All 21 patients had successful hepatectomy with complete consistency between simulation and actual surgery.
- The calculus depletion rate was 95.2%.
- Intra- and postoperative complications occurred in 19.0% of patients.
Conclusions:
- 3D-guided protective hepatectomy is effective for hepatolithiasis, ensuring calculus removal and bile drainage.
- This technique maximizes preservation of functional liver tissue.
- It potentially reduces surgical complications and improves patient outcomes.
