Where is ectopic pancreatic tissue typically found during an EGD?

Ectopic pancreatic tissue is typically found in the antrum, which is the lower portion of the stomach that connects to the duodenum. This condition occurs when pancreatic tissue is misplaced outside its normal anatomical location, and the antrum is one of the most common sites for such ectopic tissue to occur. During an esophagogastroduodenoscopy (EGD), the presence of this abnormal tissue can be identified in the antrum, often appearing as small nodules or masses.

The antrum’s relevance in this context is also tied to the embryological development of the gastrointestinal tract, where pancreatic tissue can sometimes fail to fully migrate to its designated location. As a result, the location of ectopic pancreatic tissue in the antrum may be associated with various gastrointestinal symptoms, and it can also be assessed for potential complications, such as inflammation or neoplasia.

While ectopic pancreatic tissue can occasionally be found elsewhere within the gastrointestinal tract, such as the duodenum, jejunum, or pylorus, these locations are less common compared to the antrum, which reinforces the notion that the antrum is the typical site for this condition.
