Left Lobe of Liver
The left lobe is smaller and more flattened than the right. It is situated in the epigastric and left hypochondriac regions. Its upper surface is slightly convex and is moulded on to the diaphragm; its under surface presents the gastric impression and omental tuberosity. It rarely extends more than six centimeters beyond the left margin of the sternum. It overlaps and almost completely covers the stomach when it is not distended. The posterior surface of this lobe is notched for the esophagus. To the left of this notch, on the inferior surface, is the shallow gastric impression for the stomach. Between this depression and the left sagittal fissure is a slight elevation, the omental tuberosity, which lies against the lesser omentum and the lesser curvature of the stomach.
