Seventy-five percent of true gastric diverticula were located in the posterior wall of the fundus of the stomach, 2 cm below the oesophagastric junction and 3 cm from the lesser curve. False diverticula were either traction or pulsion and associated with inflammation, other diseases, or both.
In the period between the 20th and 50th day of gestation, the stomach is transformed from a fusiform swelling of the foregut into its adult form. At this time, there is a 90¡Æ rotation of the stomach, which carries with it the duodenum, the pancreas, and the dorsal mesentery. The posterior body wall and dorsal mesentery then fuse encapsulating the pancreas within the retroperitoneum and establishing its adult form.
A diverticulum of the posterior wall of the gastric fundus hypothetically could herniate through an area of dorsal mesentery before its fusion with the left posterior body wall. Initially, the diverticulum would lie superior to the pancreas. With further extension, the diverticulum could project posterior to the pancreas.
Acquired gastric diverticula in contrast are pseudodiverticula, less common and typically located in the antrum. They usually present with a background history of other gastrointestinal pathology, such as peptic ulcer disease, malignancy, pancreatitis, or gastric outlet obstruction.
