The name ‘pancreas’ is derived from the Greek ‘pan’ (all) and ‘kreas’ (flesh). The pancreas is situated in the retroperitoneum. It is divided into a head, which occupies 30% of the gland by mass, and a body and tail, which together constitute 70%. The pancreas weighs approximately 80 g. There are nine key processes that occur during pancreatic embryogenesis.
The anatomy of the pancreatic duct is variable as a result of the primordial bud development. The dorsal duct is expressed in a variable manner in the adult. The anatomy of the main duodenal papilla, also known as the ampulla of Vater, is also variable. The outlet of each duct is protected by a complex sphincter mechanism (sphincter of Oddi).
Furthermore, Dr. Sana Khan explains the imaging of pancreas. Ultrasonography is the initial investigation of choice in patients with jaundice to determine whether or not the bile duct is dilated, the coexistence of gallstones or gross disease within the liver such as metastases. Most significant pathologies within the pancreas can be diagnosed on high-quality CT scans, with three-dimensional reconstruction if necessary. With magnetic resonance imaging (MRI), the pancreas can be clearly identified, and the anatomy of the bile duct and the pancreatic duct, together with fluid collections, can be defined.
Magnetic resonance cholangiography and pancreatography (MRCP) may well replace diagnostic endoscopic cholangiography and pancreatography (ERCP) as it is non-invasive and less expensive. Endoscopic retrograde cholangiopancreatography ERCP is performed using a side-viewing fibreoptic duodenoscope. The ampulla of Vater is intubated, and contrast is injected into the biliary and pancreatic ducts to display the anatomy radiologically.
Moreover, Congenital Abnormalities, Cystic Fibrosis and its genetic testing along with Pancreas Divisum diagnosis, Endoscopic Sphincterotomy and Annular Pancreas is explained in depth.
