PATHOLOGY

Detailed explanation-1: -With the exception of the tail, the pancreas is situated in the retroperitoneal space of the abdominal cavity, in other words, behind the peritoneum.

Detailed explanation-2: -In the posterior-inferior aspect of the uncinate process, the pancreatic tissue is dissected from the retroperitoneal soft tissues, just right lateral along the superior mesenteric artery. This constitutes the uncinate (retroperitoneal) margin (see below).
