Either the middle anastomosis atrophies and the inferior preduodenal anastomosis remains patent, resulting in a preduodenal position of the portal vein, or the portal vein develops normally but an associated malrotation of the foregut, e.g.
While this study focused on just one part of endoderm internalization, the hindgut, it is still unknown how the foregut, which forms the trachea, lungs, esophagus, stomach, and liver, and the midgut, which forms the pancreas and small intestine, are formed.
