Suprarenal (adrenal) glands
Aorta

Pancreas (except tail)
Ureters
Colon (ascending and descending) *surgeons consider these intraperitoneal
Kidney
Esophagus (thoracic portion)
Rectum (partially)
- Includes GI structures that lack a mesentery and non-GI structures
Structures become retroperitoneal two ways:
- Develop without a posterior peritoneum against the posterior body wall and only have an anterior peritoneum
- Develop as an intraperitoneal organ with a mesentery, and then move / are pushed back (like the pancreas (except tail), the 2nd to 4th part of the duodenum, and the ascending/descending colon) against the posterior abdominal wall and fuse with the body wall (secondarily retroperitoneal)
