Overview
Historical Perspective
The concept of pancreas and pancreatic duct was first described by Johannes Wirsung of Padua in 1642. In 1761, Giovanni Morgagni described the clinical syndrome of severe upper abdominal pain, vomiting, and collapse. He is also credited with the earliest pathological recognition of cancer of the pancreas. In 1948, Eliason and Welty described distal pancreatectomy (DP). In 1980, Beger described duodenal-preserving pancreatic head resection (DPPHR) technique for chronic pancreatitis to decrease the morbidity of pancreatic head resection. In 1961, Sarles proposed autoimmunity as a pathogenetic mechanism of pancreatitis. In 1995, Yoshida proposed the term "autoimmune pancreatitis" for the first time. Autoimmune pancreatitis is also known as primary inflammatory pancreatitis, lymphoplasmacytic sclerosing pancreatitis, pseudotumorous pancreatitis, chronic pancreatitis with irregular narrowing of the main pancreatic duct, idiopathic chronic pancreatitis, and nonalcoholic duct destructive chronic pancreatitis. In 2009, the two types of autoimmune pancreatitis were first identified such as type 1 (lymphoplasmacytic sclerosing pancreatitis) and type 2 (idiopathic duct-centric pancreatitis).
