The lesser curvature of the stomach forms the upper right or medial border of the stomach. [3] The lesser curvature of the stomach travels between the cardiac and pyloric orifices . It descends as a continuation of the right margin of the esophagus in front of the fibers of the right crus of the diaphragm , and then, turning to the right, it ...
The lesser curvature of the human stomach is supplied by the right gastric artery inferiorly and the left gastric artery superiorly, which also supplies the cardiac region. The greater curvature is supplied by the right gastroepiploic artery inferiorly and the left gastroepiploic artery superiorly.
The superior gastric plexus (gastric or coronary plexus) accompanies the left gastric artery along the lesser curvature of the stomach, and joins with branches from the left vagus nerve. The term "inferior gastric plexus" is sometimes used to describe a continuation of the hepatic plexus.
In human anatomy, the left gastric artery arises from the celiac artery and runs along [1] the superior portion of [citation needed] the lesser curvature of the stomach before anastomosing with the right gastric artery (which runs right to left [citation needed]).
The angular incisure (or angular notch) is a small notch on the stomach. It is located on the lesser curvature of the stomach near the pyloric end. Its location varies depending on how distended the stomach is. [1] The angular incisure is used as a separation point between the right and left portions of the stomach, the body and the pylorus. [2]
The left gastric vein runs from right to left along the lesser curvature of the stomach. [2] It passes to the esophageal opening of the stomach, where it receives some esophageal veins. [2] It then turns backward and passes from left to right behind the omental bursa. It drains into the portal vein near the superior border of the pancreas. [2]
Dissection is then performed along the lesser curvature of the stomach. [9] The right gastric artery is divided between clamps and ligated. [9] The front and back layer of the lesser (gastrohepatic) omentum is severed individually. [9] The actual resection starts with the cutting of the duodenum between holding or guy sutures. [9]
The hepatogastric ligament or gastrohepatic ligament connects the liver to the lesser curvature of the stomach. It contains the right and the left gastric arteries. In the abdominal cavity, it separates the greater and lesser sacs on the right. It is sometimes cut during surgery in order to access the lesser sac.
