Is ectopic pancreas congenital?

Ectopic pancreas is usually congenital.

At 6 - 7 weeks of human embryo, when the dorsal and ventral pancreatic primordia rotate and fuse with the upper digestive tract, ectopic pancreas may occur if one or more pancreatic primordial cells are not rotated to their normal position, but are carried away to other locations, such as the stomach, duodenum, jejunum, gallbladder, omentum or spleen. Ectopic pancreas is therefore congenital.

However, it should be noted that ectopic pancreas is only a developmental anomaly, and if it is small in size and does not cause any symptoms of compression or intestinal obstruction, it usually does not require special treatment.
