chronic pancreatitis Flashcards
what is it?
irreversible parenchymal atrophy and fibrosis leading to impaired endocrine and exocrine function and recurrent abdominal pain.
aetiology?
ALCOHOL - 70%
Idiopathic - 20%
Most commonly associated with?
chronic alcohol ingestion (>75%).
Hallmark features are?
epigastric abdominal pain radiating to the back
steatorrhoea - excretion of abnormal amount of fat with faeces
malnutrition
diabetes mellitus.
Difference between acute and chronic pancreatitis?
Acute pancreatitis is a self-limiting and reversible pancreatic injury associated with mid-epigastric abdominal pain and elevated serum pancreatic enzymes, whereas;
chronic pancreatitis is characterised by recurrent or persistent abdominal pain and progressive injury to the pancreas and surrounding structures, resulting in scarring and loss of function.
becareful not to confuse reccurent acute pancreatitis for chronic
Presenting symptoms?
Pain is epigastric, dull, radiating to the back, diminished by sitting forwards,
Worse approximately 30 minutes post-prandially - after eating
Steatorrhea
weight loss, malnutrition
nausea, vomiting
sometimes; jaundice SOB joint pain abdo distension
risk factors?
alcohol smoking coeliac disease FH psoriasis high fat high protein diet
signs?
epigastric tenderness
ivx?
blood glucose - elevated
abdo ct or MRI - pancreatic calcifications, focal or diffuse enlargement of the pancreas, ductal dilation, and/or vascular complications
others;
feacal elastase1 - low (if severe)
igG4 - positive in autoimmune pancreatitis
biopsy - increased connective tissue, loss of acini, inflammation
abdo us - calcifications, structure changes
abdo xray - calcifications
MRCP - beading of main pancreatic duct, others abnormal
Treatment?
acute episodic pain;
ibuprofen or paracetmol AND tramadol
later escalated to stronger analgesics if necessary
chronic pain;
stop smoking and drinking
analgesics
pancreatic enzymes (pancreatin) + PPI (omeprazole)
Treatment if intractable pain and calcifications?
ESWL
extracorporeal shockwave lithotripsy
