Segmentectomy completed by V- or U-shaped stapling. (A) The design of U-shaped stapling in right S2b+3a combined subsegmentectomy as an example. Initial staplings should be done from periphery from points x and z to y1/y2 and w1/w2, respectively, and then the third stapling connects y1/y2 and w1/w2; (B) completed U-shaped stapling. Although the stapling is intended to be U-shaped, the staple line is usually stretched after completion and appears as an almost straight line; (C) an intraoperative view showing a completed U-shaped stapling in an S2b subsegmentectomy with excellent inflation of the remaining lung. Arrows indicate points corresponding to “Y” and “W” in the illustrations.
