Figure 1. a. Making the greater omental flap. The greater omental flap, based on the right gastroepiploic vessels, was made by dividing the left side of the greater omentum from the transverse colon and stomach (arrow). b. The cut surface of the liver after left-sided hepatobiliary resection. Before the cut surface of the liver is covered with the greater omental flap, the appearance is similar to that in the control group (non-OF group). c. Covering the cut surface of the liver with the greater omental flap. In the greater omental flap group (OF group), the cut surface of the liver was covered by the greater omental flap without any fixation.
