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

Abstract

Purpose: Functional preserving sublobectomy (FPSL), a novel balancing strategy for segmentectomy and wedge resection, allows rapid and accurate removal of invisible nodules without the use of any preoperative localization markers. This study aimed to share single-center experience of lateral dorsal basal lung resection based on FPSL, so as to provide new surgical options for thoracic surgeons.

Methods: A retrospective analysis was performed on 13 patients who underwent thoracoscopic basal lung resection after FPSL at XX hospital from January 2021 to August 2022.

Results: The operation was successfully performed in 13 patients by using FPSL, including 12 patients with malignant tumors. The mean operating time was 107.5 ± 25.6 min. The mean postoperative hospital stay was 3.7 ± 2.4 days. None of the patients needed extended excision, such as an entire basal or inferior lobectomy.

Conclusion: Our single-center experience showed that the FPSL method only dealt with the target vessels, which greatly reduced the technical difficulty of surgery. In addition, both arteries and veins could be used as target vessels, and in particular cases such as undeveloped interlobar fissure, the operation could still be completed successfully. Lateral dorsal basal lung resection based on FPSL may be a new surgical option for surgeons.
