Pancreas is which type of organ and where is it located relative to the lesser sac?

• A. Retroperitoneal
• B. Intraperitoneal
• C. Extraperitoneal
• D. Subperitoneal

Answer: (A)

The pancreas sits behind the peritoneum, so it is retroperitoneal. In relation to the lesser sac, the pancreas forms its posterior boundary—the lesser sac lies anterior to the pancreas, which sits in the retroperitoneal space between the stomach and the posterior abdominal wall. Although the tail near the spleen has some peritoneal connections, the majority of the gland is retroperitoneal, which is why that descriptor fits best.
