Lateral Dorsal Basal Lung Resection Based on Functional Preserving Sublobectomy Method: Single-Center Experience

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Minimally Invasive Procedures

Background:

• Invisible pulmonary nodules present a surgical challenge.
• Traditional segmentectomy and wedge resection may require preoperative localization.
• Accurate and efficient resection is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the efficacy and safety of Functional Preserving Sublobectomy (FPSL) for lateral dorsal basal lung resection.
• To present a single-center experience with FPSL as a novel surgical strategy.
• To offer thoracic surgeons a new option for resecting difficult-to-access lung lesions.

Main Methods:

• Retrospective analysis of 13 patients undergoing thoracoscopic basal lung resection using FPSL.
• Data collected from January 2021 to August 2022 at a single institution.
• Focus on operative details, outcomes, and technical aspects of FPSL.

Main Results:

• Successful FPSL performed in all 13 patients, with 12 cases involving malignant tumors.
• Mean operative time: 107.5 ± 25.6 minutes; mean postoperative hospital stay: 3.7 ± 2.4 days.
• No patients required extended resection (e.g., lobectomy), indicating precise tumor removal.

Conclusions:

• FPSL simplifies surgery by focusing on target vessels, reducing technical difficulty.
• The technique is adaptable, even in cases with undeveloped interlobar fissures.
• Lateral dorsal basal lung resection using FPSL represents a promising new surgical option.
