a Intraoperative image of the staple-line that divided the anterior interlober fissure. An intraoperative image of the staple-line that divide the anterior interlober fissure is shown. Although some staples (white arrow) protrude perpendicularly to the cut surface, no malformed staples are noted. b Constructed three-dimensional computed tomography. A three-dimensional computed tomography image is constructed using postoperative enhanced computed tomography. The contrast extravasation (shown in red) is on the staple line dividing the interlobar fissure (shown in yellow). The multiple firing junction is indicated by the white arrow. c Side image of constructed three-dimensional computed tomography. A side image of the constructed three-dimensional computed tomography is shown. This image reveals that the top edge of contrast extravasation is the bleeding point (white arrow), which is close to the multiple firing junction
