The severity of ectopic pancreas depends on its location, size and nature of the lesion, and may be accompanied by abdominal pain, bleeding, perforation and other symptoms. Ectopic pancreas is a condition in which the pancreatic tissue appears outside its normal anatomical location, such as in the gastrointestinal tract, and is therefore also known as a vagal pancreas. The severity of an ectopic pancreas is related to the symptoms that may accompany it, which are inextricably linked to its location, size, and other factors. For example, if the ectopic pancreas is in the stomach, it may cause ulceration, bleeding or even acute gastric perforation due to the secretion of various corrosive enzymes such as trypsin by the pancreatic tissues; and when it occurs in the vicinity of the duodenal papillae, it may cause obstructive jaundice and other compression symptoms. These are more serious cases. It is recommended that patients with ectopic pancreas consult a doctor in a timely manner, according to the specific conditions and then do the appropriate treatment.
