THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The splenic vein runs immediately posterior to the length of the body of the pancreas and receives the inferior mesenteric vein 2–3 cm before joining the superior mesenteric vein (see Figure 3). Just lateral to the left renal hilum the tail of the pancreas extends into the lienorenal ligament.

Detailed explanation-2: -Pancreatic Relationships The pancreas is separated from the stomach anteriorly by the lesser sac of the peritoneal cavity. The pancreatic tail courses in the splenorenal ligament along with the splenic vessels, rendering this portion of the pancreas intraperitoneal.

Detailed explanation-3: -The pancreas is mostly within the retroperitoneum in the anterior pararenal space. However, the tail of the pancreas is actually an intraperitoneal structure and in close relationship with the splenorenal ligament. To best understand the anatomy of the pancreas, an understanding of embryology is necessary.
