    Abstract This review chronicles the evolution of thoracic surgical interventions, from the standardized pneumonectomy to the precise approach of sublobar resections. It discusses the emergence and acceptance of minimally invasive and robot-assisted surgical techniques, highlighting their impact on improving outcomes beyond cancer and their influence on the surgical management of early-stage lung cancer. Evaluating historical developments alongside present methodologies, this review underscores the critical need for meticulous surgical planning and execution to optimize both oncological radicality and functional preservation. This evolution portrayed not only technical advancements but also a shift in the clinical approach towards tailored, organ-preserving methodologies, culminating in a contemporary framework promoting sublobar resections as the standard for specific patient profiles, signifying a new era of precision in thoracic surgery.

    Abstract Background: In real-time tumor-tracking radiotherapy for lung tumors, placement of fiducials, such as a gold marker (GM), is necessary. However, transbronchially placed GMs often drop out spontaneously. Therefore, we aimed to clarify the fixation rate of GMs in each segmental bronchus.
    Methods: In this study, we examined the fixation rates of 791 GMs placed in 235 patients (259 procedures), from November 2011 to November 2020, at a single facility. The relationship between the elapsed time and the fixation rate was assessed using the Kaplan-Meier method. Moreover, we measured the distance between the GM and the chest wall (DMC), as confirmed using planning computed tomography, and analyzed the relationship of this distance with the fixation rate.
    Results: Overall, 28.8% of GMs dropped out within 10 days of placement. The fixation rate of GMs in the bronchi was significantly lower in the upper lobe than in the other lobes, in both lungs (right, p < 0.01; left, p = 0.05). Moreover, in the left upper lobe, the fixation rate of GMs was significantly lower in B
    Conclusions: The fixation rate of GMs was lower in the upper lobes than in the lower lobes. Additionally, the fixation rate was lower in B

    Abstract The clinical application of three-dimensional computed tomography (3D-CT) technology has rapidly expanded in the last decade and has been applied to lung cancer surgery. Two consecutive reports of large-scale prospective clinical trials from Japan and the United States have brought a paradigm shift in lung cancer surgery and may have led to a rapid increase in sublobar lung resections. Sublobar resection, especially segmentectomy, requires a more precise understanding of the anatomy than lobectomy, and preoperative 3D simulation and intraoperative navigation support it. The latest 3D simulation software packages are user-friendly. Therefore, in this narrative review, we focus on recent attempts to apply 3D imaging technologies, particularly in the sublobar resection of the lung, and review respective research and outcomes. Improvements in CT accuracy and the use of 3D technology have advanced lung segmental anatomy. Clinical applications have enabled the safe execution of complex sublobar resection through a minimally invasive approach, such as video-assisted thoracoscopic surgery and robotic surgery. However, currently, many facilities still render 3D images on two-dimensional monitors for usage. In the future, it will be challenging to further spread and advance intraoperative navigation through the application of 3D output technologies such as extended reality.

    Abstract With the progress of surgical instruments and surgical techniques, endoscopic surgery has become remarkably widespread, and techniques of the thoracoscopic surgery are considered to have become common. It is not uncommon to encounter cases with intrathoracic pleural adhesions, such as not only a history of intrathoracic inflammatory disease, but also second cancer after resection of early-stage lung cancer and multiple operations for metastatic lung tumor. It is important for thoracic surgeons to have a technique that enables thoracoscopic adhesiolysis without open thoracotomy to maintain the quality of life (QOL) and activity of daily living (ADL) of the patient. In this article, we would like to describe the concept of video-assisted thoracoscopic surgery for cases with intrathoracic pleural adhesions to avoid a conversion to open thoracotomy.

    Abstract A recent randomized trial demonstrated the survival superiority of lung segmentectomy over lobectomy in patients with early stage, small-sized lung cancer. Hence, there is a pressing need for thoracic surgeons to gain familiarity with lung segmentectomy. However, lung segmentectomy, especially via minimally invasive surgery, is a technically challenging thoracic surgical procedure. The robotic surgery platform helps surgeons to improve their operative performance based on its core technological features: improved dexterity, precision, and visualization. Herein, we have discussed the key issues related to robotic lung segmentectomy, explicitly focusing on the technical features of complex segmentectomy under difficult conditions. We have also introduced our preferred surgical strategy for robotic lung segmentectomy with specific maneuvers.
