There is every possibility that you might find parietal cells that are normally located in the stomach down the Meckel diverticulum. That is the definition of a choristoma or heterotropic rest. Do not forget that. This is in fact the two diverticulum and then may contain the gastric mucosa, that of course referring to, once again a heterotropic rest.
