Clinical Report: Utilizing Preoperative 3D Reconstruction in Laparoscopic Surgery

Overview

This pilot study investigates the use of preoperative 3D reconstruction in laparoscopic distal pancreatectomy (LDP).

Background

Laparoscopic distal pancreatectomy is a complex procedure that requires precise preoperative assessment to determine the feasibility of spleen preservation. Traditional imaging techniques like CT and MRI provide limited two-dimensional views, which can complicate surgical planning. The integration of 3D reconstruction offers a more detailed visualization of anatomical relationships.

Data Highlights

This study included two adult patients undergoing elective LDP, where 3D reconstruction influenced surgical strategy and confirmed intraoperative findings.

Key Findings

• 3D reconstruction influenced the surgical strategy regarding spleen management in both cases.
• In the first case, planned splenectomy was due to close tumor involvement with splenic vessels.
• The second case supported a spleen-preserving approach based on preserved separation from vessels.
• Intraoperative findings confirmed the preoperative 3D assessment in both patients.
• Histology revealed well-differentiated neuroendocrine tumors in both cases.

Clinical Implications

The use of preoperative 3D reconstruction may enhance surgical planning and decision-making regarding spleen preservation strategies.

Conclusion

Preoperative 3D reconstruction may facilitate anatomical understanding and surgical planning in laparoscopic distal pancreatectomy.
