Using blunt dissection techniques, identify the vessels along the lesser curvature of the stomach. To have an adequate exposure for this dissection it may be necessary to remove the left lobe of the liver . On the right side of the lesser curvature of the stomach, identify the right gastric artery, which is a branch of the proper hepatic artery. It lies along the lesser curvature of the stomach and anastomoses with the left gastric artery. The left gastric artery originates directly from the celiac trunk. It runs on the posterior wall of the lesser sac, covered by the gastropancreatic fold, to the superior aspect of the lesser curvature of the stomach Attempt to identify the esophageal branches of the left gastric artery which supply the abdominal portion of the esophagus. Along the anterior and posterior aspects of the lesser curvature of the stomach, identify the gastric branches of both the right and left gastric arteries (Figure 38.1).
