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 incision follows at an angle of 45 degrees to the lesser curvature. [9] The staple line can, but need not, be oversewn. [9] After removal of the distal portion (including the antrum and the pylorus) of the stomach, a clamp is fitted at right angles to the greater curvature. [9]
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 anterior gastric branches of anterior vagal trunk are branches of the anterior vagal trunk which supply the stomach. [1]One long branch of it runs from the lesser curvature or parallel to it in lesser omentum as far as the pyloric antrum to fan out into branches in a way like the digits of a crow's foot to supply the pyloric antrum and the anterior wall of pyloric canal.
Greater curvature * 5. Lesser curvature * 6. Cardia * 9. Pyloric sphincter * 10. Pyloric antrum * 11. Pyloric canal * 12. Angular incisure * 13. Gastric canal * 14. Rugal folds. The pylorus is the furthest part of the stomach that connects to the duodenum.
A benign gastric ulcer (from the antrum) of a gastrectomy specimen. Gastric ulcers are most often localized on the lesser curvature of the stomach. The ulcer is a round to oval parietal defect ("hole"), 2–4 cm diameter, with a smooth base and perpendicular borders.
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 antrum rotates in opposite direction to the fundus of the stomach. This is the most common type of gastric volvulus, occurring in approximately 59% of cases, and it is usually associated with diaphragmatic defects. Strangulation and necrosis commonly occur with organoaxial gastric volvulus and have been reported in 5–28% of cases.
