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.
The Ranson criteria form a clinical prediction rule for predicting the prognosis and mortality risk of acute pancreatitis. They were introduced in 1974 by the English - American pancreatic expert and surgeon Dr. John Ranson (1938–1995).
Pancreatic abscess is a late complication of acute necrotizing pancreatitis, occurring more than 4 weeks after the initial attack. A pancreatic abscess is a collection of pus resulting from tissue necrosis, liquefaction, and infection. It is estimated that approximately 3% of the patients with acute pancreatitis will develop an abscess. [1]
This resulted in 132,700 deaths, up from 83,000 deaths in 1990. [7] [8] Acute pancreatitis occurs in about 30 per 100,000 people a year. [3] 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. [9] It is more common in men than women. [1]
About 85% of these patients had a single cyst. Cysts ranged in size from 2 to 38 mm (mean, 8.9 mm). There was a strong correlation between the presence of cysts and age. No cysts were identified among patients less than 40 years of age, while 8.7 percent of the patients aged 80 to 89 years had a pancreatic cyst.
Pancreas. Frey's procedure is a surgical technique used in the treatment of chronic pancreatitis in which the diseased portions of the pancreas head are cored out. A lateral pancreaticojejunostomy (LRLPJ) is then performed in which a loop of the jejunum is then mobilized and attached over the exposed pancreatic duct to allow better drainage of the pancreas, including its head.
Liquefactive necrosis (or colliquative necrosis) is a type of necrosis which results in a transformation of the tissue into a liquid viscous mass. [1] Often it is associated with focal bacterial or fungal infections, and can also manifest as one of the symptoms of an internal chemical burn. [2]
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 .
