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]
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.
The greater curvature, which begins at the cardiac notch, and arches backwards, passing inferiorly to the left, [1] is four or five times longer than the lesser curvature, [2] which attaches to the hepatogastric ligament and is supplied by the left gastric artery and right gastric branch of the hepatic artery.

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.
Dieulafoy's lesion (French:) is a medical condition characterized by a large tortuous artery [2] most commonly in the stomach wall that erodes and bleeds.It can present in any part of the gastrointestinal tract. [3]
The approach is mainly from the anterior wall of the maxilla bone. It was introduced by George Caldwell (1893)and Henry Luc (1897). The maxillary sinus is entered from two separate openings, one in the canine fossa to gain access to the antrum and other in the naso antral wall for drainage. [1]

Gastrin is secreted by the G cells.G cells are primarily found in the pyloric antrum but can also be found in the duodenum and the pancreas. [12] The primary function of gastrin is to induce the release of hydrochloric acid (HCl) from the parietal cells located in the fundus of the stomach.
