In medicine, a pancreatectomy is the surgical removal of all or part of the pancreas. Several types of pancreatectomies exist, including pancreaticoduodenectomy (Whipple procedure), distal pancreatectomy, segmental pancreatectomy, and total pancreatectomy.
There are about 1 million islets distributed throughout the pancreas of a healthy adult human. While islets vary in size, the average diameter is about 0.2 mm. [5]:928 Each islet is separated from the surrounding pancreatic tissue by a thin, fibrous, connective tissue capsule which is continuous with the fibrous connective tissue that is interwoven throughout the rest of the pancreas.
It is also used for the treatment of pancreatic or duodenal trauma, or chronic pancreatitis. [2] Due to the shared blood supply of organs in the proximal gastrointestinal system, surgical removal of the head of the pancreas also necessitates removal of the duodenum, proximal jejunum, gallbladder, and, occasionally, part of the stomach.

One cause of Type 1 diabetes is through surgery. This is due to the destruction or intentional removal of a portion of or the entire pancreas. This greatly decreases the number of beta-islet cells capable of producing insulin, resulting in an acquired form of Type 1 diabetes known as pancreatogenic diabetes mellitus. [41]
Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack or reduction of digestive enzymes made by the pancreas.EPI can occur in humans and is prevalent in many conditions [1] such as cystic fibrosis, [2] Shwachman–Diamond syndrome, [3] different types of pancreatitis, [4] multiple types of diabetes mellitus (Type 1 and Type 2 diabetes), [5] advanced ...
In adults in the United Kingdom, the estimated average total direct and indirect costs of chronic pancreatitis is roughly £79,000 per person on an annual basis. [48] Acute recurrent pancreatitis and chronic pancreatitis occur infrequently in children, but are associated with high healthcare costs due to substantial disease burden . [ 49 ]
In adult pancreas samples, they are observed to be round or oval shaped and remain localized on the mantle of the islets in different amounts, both in clusters and or single cells. In mice, ε-cells are present in the pancreatic islets and stomach during development, but are found strictly in the stomach after birth.
Acute pancreatitis (AP) is a sudden inflammation of the pancreas.Causes include a gallstone impacted in the common bile duct or the pancreatic duct, heavy alcohol use, systemic disease, trauma, elevated calcium levels, hypertriglyceridemia (with triglycerides usually being very elevated, over 1000 mg/dL), certain medications, hereditary causes and, in children, mumps.
