Pancreatitis Flashcards
What is pancreatitis?
Inflammation of the pancreas (acute or chronic)
What is acute pancreatitis?
Sudden & short-lived inflammation of the pancreas - normal function returns after inflammation goes away - can cause long-term complications
What is chronic pancreatitis?
Long-lasting inflammation - periodically symptomatic - permanent damage of the pancreas - scarring
Symptoms of acute pancreatitis
Sudden severe pains & cramps in the abdomen, nausea/emesis, diarrhoea, fever, indigestion, jaundice, tachycardia
Aetiology of acute pancreatitis
Gallstones, excessive alcohol consumption
How are gallstones formed?
Bile in the gallbladder hardens into a stone-like material due to high cholesterol, bile salts, and/or bilirubin
What is it called when gallstones are present in the gallbladder?
Cholelithiasis
What is it called when gallstones are present in the bile duct?
Choledocholithiasis
What are the two main types of gallstones?
Cholesterol stones & pigment stones
How do cholesterol stones form?
Bile is oversaturated with cholesterol - decrease in bile production or increase in cholesterol consumption
How are pigment stones formed?
Disruption of bilirubin by bacterial enzymes - calcium product formed - forms stones - higher risk if you suffer from liver disease, obesity, chronic alcoholic
Treatment of Gallstones
Oral dissolution therapy (drink) (cholesterol stones) -recurs in >50% in 5 years
Keyhole surgery - removal of connection between gallbladder, bile ducts, & liver
Chronic alcohol consumption and acute pancreatitis
Cause 17-25% cases of acute pancreatitis, usually people who drink >5 units of alcohol daily for 5 years, alcohol affects acinar cells & small pancreatic ducts, cause precipitation and increase viscosity of pancreatic secretions, protein plugs develop in small ducts -> calculi -> inflammation & fibrosis -> chronic pancreatitis - leads to premature activation of pancreatic enzymes (autodigestion)
Diagnosis of acute pancreatitis
Serum amylase and lipase analysis, CT scans, endoscopy, clinical presentations (abdomen pain e.g. tenderness & palpitations)
-Alcohol-related acute pancreatitis ~ liver panel tests, calcium determination and triglyceride measurement
Treatment of acute pancreatitis
IV treatment for dehydration, Oxygen via ventilation, painkillers, antibiotics, liquid diet, treat gallstones & other symptoms
What causes acute pancreatitis to become chronic pancreatitis?
Fibrosis, calcification, inflammation of ducts, & repeated incidence of acute pancreatitis
Symptoms of chronic pancreatitis
Emesis, a dull relentless to a more severe abdomen pain, epigastric tenderness, unexplained weight loss, steatorrhoea, glucose intolerance
Diagnosis of chronic pancreatitis
Serum enzymes (not as much of an increase as acute pancreatitis), determination of DM status, x-ray, exocrine function test using endoscopy
Complications of chronic pancreatitis
Related to fat malabsorption, malnutrition, DM (80% of patients due to damage of pancreas) , biliary obstruction (scaring of bile ducts), pseudocysts (build up of pancreatic juices outside ducts), duodenal obstruction, pancreatic fistula (abnormal opening from pancreas to pancreatic duct), & pancreatic ascites (collection of pancreatic fluid in abdomen)
Pathogenesis of chronic pancreatitis
Replacement of healthy pancreatic tissue with fibrotic tissue - sessions begin in exocrine glands before attacking islets - development of calcium and protein stones (lithiasis)
Risk factors for chronic pancreatitis
High continuous alcohol consumption, high protein & fat diet, tobacco consumption, intergenerational malnutrition
Non-surgical treatment of chronic pancreatitis
Pain relief, enzyme therapy to stop diarrhoea & help weight gain, high protein & calorie diet, nerve treatment, stents to open narrow areas, surgery to remove stones
Surgical treatment of chronic pancreatitis
Longitudinal pancreaticojejunostomy (clear blocked pancreatic duct), remove pancreas and autotransplantation of islet cells to the liver, Whipple procedure (partial removal of pancreas, duodenum, part of the bile duct, the gall bladder, & maybe part of the stomach ~ the surgeon then connects the remaining organs), & partial removal of pancreas
