Gastric ectopic pancreas belongs to a kind of congenital malformation, which refers to the appearance of pancreatic tissue in the stomach that is not related to the pancreas in its normal position.
In 90% of cases, the ectopic pancreas is found in the stomach. This ectopic pancreatic tissue has no connection with the normal pancreas in terms of blood vessels, nerves, and other anatomical structures, and it is an independent malformation. However, it also has common features with the normal pancreas, such as the ability to secrete physiological substances such as trypsin.
Gastric ectopic pancreas that does not cause symptoms can be followed up with regular gastroscopy and other examinations without special treatment. However, if the secretion of trypsin and other substances corrode the mucous membrane of the stomach and duodenum, resulting in ulcers or bleeding, surgical removal should be considered.
