    Abstract:
    Accumulation of experience and advances in techniques and instruments have enabled surgeons to perform video-assisted thoracic surgery (VATS) safely for sublobar resection, including segmentectomy and wedge resection. A key to successful VATS sublobar resection is to have adequate resection margins and the appropriate use of articulated surgical staplers is essential for this purpose. The SigniaTM stapling system (Covidien Japan, Tokyo) has been used extensively in the fields of thoracic surgery. Its features include high maneuverability with fully powered articulation, rotation, clamping, and firing, which the surgeon can control with one hand. We introduce the "sliding technique" using the SigniaTM system, which allows for adjustment of the resection lines of the pulmonary parenchyma to optimize safe surgical margins with minimal stapler movement, and without repetitively moving the stapler in and out of the pleural cavity, during VATS sublobar resection.
