The small intestine is located intraperitoneally and is divided anatomically into the: Duodenum, which is continuous with the gastric pylorus, where the common bile duct (ductus choledochus) and the pancreatic duct lead into the major duodenal papilla. These are formed by invagination of the crypt space between the villi into the lamina propria of the mucosal layer. The base of the villus is called the CRYPT of LIEBERKUHN or INTESTINAL CRYPT. Frequently the cells lining the crypts near the areas of neoplastic involvement and the crypts themselves were two or more times larger than their usual size.
