To understand the peritoneal attachments of the spleen and their surgical applications, the embryologic changes which take place must be understood. The stomach (before rotation) is attached posteriorly by a dorsal mesogastrium and anteriorly by a ventral mesogastrium (Fig. 459 A). The spleen originates as a localized cellular collection in the left layer of the dorsal mesogastrium. These cellular collections fuse with one another to form a lobulated spleen, the notch or notches of which are the only surface traces of lobulation in the adult organ.
