Annular pancreas
During the embryonic period, the two pancreatic buds (pancreas and accessory pancreas) are not in the correct position for healing. When the duodenum rotates, the ventral pancreatic bud is fixed and elongated. When it later joins with the dorsal pancreatic bud, it encircles the descending part of the duodenum, compressing the duodenum and causing high intestinal obstruction, which is called annular pancreas. The pancreatic head of the annular pancreas is still located within the duodenal arc. The tissue of the annular part contains the same islet and acinar tissue as the normal pancreas.
