Summary

The purpose of this study is to evaluate the safety and effectiveness of a specialized surgical technique called "Septum-guided Segmentectomy" for treating early-stage lung cancer located deep within the lung tissue.Standard surgery for lung cancer often involves removing an entire lung lobe (lobectomy), which can significantly reduce a patient's breathing capacity. For small tumors, removing only a segment of the lung (segmentectomy) can preserve more healthy tissue. However, for tumors located deep in the lung, traditional segmentectomy is technically challenging and risks leaving cancer cells behind.In this study, surgeons will use the natural anatomical boundaries-the intersegmental veins and their surrounding thin membranes (septa)-as a guide to precisely remove the target lung segment. This "septum-guided" approach aims to ensure the cancer is completely removed while maximizing the preservation of healthy lung function.Participants will be followed for 3 years after surgery to monitor for cancer recurrence and assess their long-term recovery.

PROCEDURE

Septum-guided Segmentectomy

This procedure is performed via single-port VATS or Robot-assisted Thoracic Surgery (RATS). The core technique involves the precise identification of the intersegmental veins and their surrounding fibrous sheath (septum). These natural anatomical boundaries are utilized to guide the separation and resection of the target lung segment. Unlike traditional methods that rely on fixed safety margins, this approach focuses on anatomical planes to ensure oncological safety for deep-seated lesions. Systematic lymph node sampling or dissection of at least 3 hilar and 3 mediastinal groups is mandatory. An intraoperative second registration is conducted to confirm the nodal status and anatomical suitability before finalizing the resection.
