Ectopic pancreatic tissue
 Discussion of Ectopic pancreatic tissue
- Ectopic rests of pancreatic tissue are usually located in either:
- Submucosa of the gastric antrum or
- Proximal portion of the duodenum
- Ectopic pancreatic tissue usually represents an incidental finding
- If the ectopic pancreatic tissue is functional, it is subject to the same inflammatory and neoplastic disorders that involve the normal pancreas.
- Laparoscopic gastric wedge resection is a safe and effective treatment for symptomatic pancreatic rests located in the stomach.
 Imaging Findings for Ectopic pancreatic tissue
- On upper gastrointestinal examination, an ectopic pancreas appears as an extramucosal, smooth, broad-based lesion either along the greater curvature of the gastric antrum or in the proximal duodenum.
- In 45% of the cases of ectopic pancreas discovered on upper gastrointestinal examination, the ectopic pancreatic tissue contains a central small collection of barium, which is indicative of a central niche or umbilication. It is this finding that is diagnostic of ectopic pancreatic tissue
