Acute Pancreatitis Flashcards
What is acute pancreatitis
The inflammation of the pancreatic parenchyma Q
What are two features pancreatitis
Fat necrosis
Oedema
What features are common in a blood test for someone with acute pancreatitis
High Serum amylase levels
Raised lipase enzymes
What are the main causes for acute pancreatitis
Gall stones
Alcohol
Trauma
What is the pathological reason for the inflammation in acute pancreatitis from gall stones
The destructive effects of built up activated pancreatic enzymes
What is the pathological reason for the inflammation in acute pancreatitis from trauma/drugs
Acinar cells can get damaged
What is the pathological reason for the inflammation in acute pancreatitis from alcohol
Alcohol increases enzyme secretion which has destructive effects on the pancreas and creates leaky vessels
Why do you get fat necrosis in acute pancreatitis
Fatty-tissue necrosis is probably caused by lipase (one of the few pancreatic enzymes that need no activation) after an abrupt effusion of zymogens from peripheral acinar cells into the interstitial space
What group of enzymes causes fat necrosis in acute pancreatitis
Lipolytic enzymes
What does the released fat in fat necrosis do?
It binds calcium causing hypocalcaemia in the body
What group of enzymes destroy acinar tissue, blood vessels and islets of langerhaans in acute pancreatitis
Proteolytic enzymes
What happens to the body if the islets of langerhaans are destroyed
Hyperglycaemia as blood glucose will rise.
What are the signs and symptoms of acute pancreatitis
Epigastric pain that radiates to back
Anorexia
Nausea and Vomitting
What are the features of grey turners sign
Grey Turner’s sign refers to bruising of the flanks, the part of the body between the last rib and the top of the hip. The bruising appears as a blue discoloration
What is Grey turner’s sign important in acute pancreatitis
It can predict a severe attack of acute pancreatitis
