Application Research of Three-Dimensional Printing Technology and Three-Dimensional Computed Tomography in...

Area of Science:

• Surgical Technology
• Medical Imaging
• Additive Manufacturing

Background:

• Thoracoscopic segmentectomy is a minimally invasive surgical procedure.
• Three-dimensional computed tomography (3D-CT) aids in surgical planning.
• Emerging 3D printing technology offers new possibilities for surgical guidance.

Purpose of the Study:

• To compare the application of 3D printing technology with 3D-CT in thoracoscopic segmentectomy.
• To explore the advantages of 3D printing in guiding thoracoscopic segmentectomy.

Main Methods:

• A retrospective analysis of 118 patients undergoing thoracoscopic segmentectomy.
• Patients were divided into a 3D printing group (61 patients) and a 3D-CT group (57 patients).
• Perioperative data were collected and analyzed for comparison.

Main Results:

• The 3D printing group showed significantly shorter operation times (162.7 ± 47.0 min vs. 190.3 ± 56.9 min) and reduced intraoperative fluid input (1,158.5 ± 290.2 ml vs. 1,433.2 ± 653.3 ml).
• No significant differences were observed in intraoperative blood loss, pleural fluid volume, chest tube duration, hospital stay, or complications.
• Patients with hypertension were more prevalent in the 3D printing group (P = 0.003).

Conclusions:

• 3D printing technology in thoracoscopic segmentectomy leads to shorter operation times and reduced intraoperative fluid management.
• The application of 3D printing enhances surgical safety and effectiveness.
• 3D printing demonstrates significant clinical value in thoracoscopic segmentectomy.
