The retroperitoneum (adj. retroperitoneal) is the anatomical space behind (retro) the abdominal cavity. It has no specific delineating anatomical structures. Organs are retroperitoneal if they only have peritoneum on their anterior side. There is a 52% chance of surviving Retroperitoneal cancer.
Secondarily retroperitoneal organs
Organs that were once suspended within the abdominal cavity by mesentery but migrated posterior to the peritoneum during the course of embryogenesis to become retroperitoneal are considered to be secondarily retroperitoneal organs.
Structures that lie behind the peritoneum are termed "retroperitoneal". These include:
- Primarily retroperitoneal:
- Secondarily retroperitoneal:
- Suprarenal glands
- Aorta and Inferior vena cava
- Pancreas (except the tail)
- Colon (ascending and descending)
