It is easy to propose that in order to perform a segmentectomy as a radical operation and equivalent treatment option to lobectomy for cT1aN0M0 non-small cell lung cancer, sufficient surgical margin and hilar regional lymph node dissection are the essential requirements. However, these 2 points are not easy. Here, we introduce our techniques. To take a sufficient surgical margin, we usually use a ring-shaped forceps to grasp the tumor, and resect the lung more than 1 cm away from the forceps. To dissect the hilar regional lymph nodes, we encircle the hilar vessels and bronchus with tape and make a sufficient field. We will introduce these points by demonstrating cases.
key words: Lung cancer, Segmentectomy, Surgical margin, Lymph node dissection, Local recurrence
