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.
Chronic pancreatitis is a long-standing inflammation of the pancreas that alters the organ's normal structure and functions. [1] It can present as episodes of acute inflammation in a previously injured pancreas , or as chronic damage with persistent pain or malabsorption .
New cases of chronic pancreatitis develop in about 8 per 100,000 people a year and currently affect about 50 per 100,000 people in the United States. [10] It is more common in men than women. [1] Often chronic pancreatitis starts between the ages of 30 and 40 and is rare in children. [1]
Autoimmune pancreatitis may cause a variety of symptoms and signs, which include pancreatic and biliary (bile duct) manifestations, as well as systemic effects of the disease. Two-thirds of patients present with either painless jaundice due to bile duct obstruction or a "mass" in the head of the pancreas, mimicking carcinoma.
Hereditary pancreatitis (HP) is an inflammation of the pancreas due to genetic causes. It was first described in 1952 by Comfort and Steinberg [ 1 ] but it was not until 1996 that Whitcomb et al [ 2 ] isolated the first responsible mutation in the trypsinogen gene ( PRSS1 ) on the long arm of chromosome seven ( 7q35 ).
The pain may be worse at night and may increase over time to become severe and unremitting. [27] It may be slightly relieved by bending forward. In the UK, about half of new cases of pancreatic cancer are diagnosed following a visit to a hospital emergency department for pain or jaundice.
