Three-Dimensional Computed Tomography Reconstruction in Uniportal Thoracoscopic Segmentectomy: A Propensity...

Area of Science:

• Thoracic Surgery
• Medical Imaging
• Surgical Oncology

Background:

• Pulmonary segmentectomy presents anatomical challenges due to vascular and bronchial variations.
• Three-dimensional (3D) reconstruction is a proposed tool to improve visualization and planning in complex thoracic procedures.

Purpose of the Study:

• To evaluate the utility of 3D reconstruction in enhancing anatomical comprehension during segmentectomy.
• To assess the impact of 3D reconstruction on surgical planning and perioperative outcomes in uniportal thoracoscopic segmentectomy.

Main Methods:

• A comparative study included 141 patients undergoing uniportal thoracoscopic pulmonary segmentectomy.
• Patients were divided into a 3D reconstruction group (51) and a non-3D group (90).
• Propensity score matching was used to compare outcomes, including operative time, blood loss, and resection margins.

Main Results:

• The 3D reconstruction group showed significantly shorter operative times (P=0.004) and less blood loss (P=0.004) compared to the non-3D group.
• No significant differences were found in resection margins, lymph node yield, or postoperative complications between the groups.
• Hospital stay and postoperative drainage were also comparable between the 3D and non-3D cohorts.

Conclusions:

• 3D reconstruction significantly enhances anatomical understanding and surgical planning for uniportal thoracoscopic segmentectomy.
• The use of 3D models leads to reduced operative time and intraoperative blood loss.
• 3D reconstruction facilitates adjustments in surgical plans while maintaining adequate resection margins and comparable postoperative outcomes.
