Diseases of the Pancreas Flashcards
(24 cards)
What is acute pancreatitis?
Normal pancreas that has now become inflamed - may return to normal
Why does acute pancreatitis occur?
Increased activation of digestive enzymes causing necrosis of pancreatic tissue, gallstones can also obstruct the pancreatic duct and cause ductal hypertension
Causes of acute pancreatitis (GET SMASHED)
Gallstones, ethanol, trauma/tumours, spider-scorpion bites, mumps/malignancy, autoimmunity, steroids, hyperlipidaemia/calcaemia, ERCP, drugs
Symptoms of acute pancreatitis
Severe epigastric pain -> back, fever, nausea, loss of appetite, tachycardia, hypotension, reduced bowel sounds if ileus, GREY TURNERS SIGN, CULLEN’S SIGN
Complications of acute pancreatitis
Pseudocysts, abscesses, pleural effusion, ARDS, organ failure, necrosis, perforation, chronic pancreatis
Investigations of acute pancreatitis
Elevated amylase, lipase and Ca FBC etc Erect CXR/AXR for pseudocysts US for stones CT for complications
Prognosis classification of acute pancreatitis
Glasgow prognosis score (PANCREAS) =/> 3 for severe pancreatitis
Treatment of acute pancreatitis
- Analgesia + IV fluids
- NJ feeding
- ERCP/cholectomy if gallstones
- Pseudocyst/abscess endoscopic drainage
What is chronic pancreatitis?
Long-term necrosis and calcification with irreversible structure changes to pancreas
What can chronic pancreatitis lead to?
Pain, splenic vein thrombosis, pleural effusion, ascites, pseudocysts, pancreatic cancer, duodenal obstruction
Endocrine deficiency - diabetes
Exocrine deficiency - enzyme def = malabsorption = steatorrhea
Causes of chronic pancreatitis
Alcohol, idiopathic, pancreatic duct obstruction , hereditary - CF + A1AT def + hyperthyroidism
Investigations of chronic pancreatitis
Diagnosis mainly on history
Amylase may be normal
CT scan shows calcification, dilated duct
Treatment of chronic pancreatitis
- Stop alcohol
- Address diabetes + enzyme supplement eg. CREON
- Opioids and NSAIDs for pain
- Endoscopic drainage of pseudcyst
- Surgery if tolerable - Pustow procedure
What is the Pustow procedure?
Joining of duo/jejunum to pancreas so pancreatic juice can drain
Types of pancreatic cancer
Adenocarcinoma (95%) - exocrine
Insulinoma, glucagonoma + gastroma - endocrine
Where does adenocarcinoma usually develop
Head of pancreas and ampulla of Vater
What causes adenocarcinoma
Smoking, alcohol, high caffeine, chronic pancreatitis, diabetes
Symptoms of adenocarcinoma
Jaundice, dark urine, pale stools, abdo and back pain, weight loss
Investigations of adenocarcinoma
US - obstructed ducts
CT - confirm mass legions
Treatment of adenocarcinoma of pancreas
- Pancreatico-duodenectomy (Whipple’s resection_
2. Palliation - pain relief, stening, cholectcystojejunectomy/gastroenterotomy
What does insulinoma cause
Increased insulin = Hypoglycaemia
What does glucagonoma cause
Increased glucagon
= hyperglycaemia
What does gastrinoma cause
Increased gastrin = acid hypersecretion = peptic ulcers
Example of gastrinoma
Zollinger-Ellison syndrome
