Acute pancreatitis Flashcards
Pathology
-Primary cause to the release/activation of pancreatic enzymes
-Pancreatic enzymes cause auto digestion
1-release of 02 free radicals or cytokines
2-oedema
3-Fat necrosis
Symptoms of pancreatitis
-Severe abdominal pain which can radiate to the back
-Nausea/Vomiting
-Abdominal distension
-Signs of infection: tachycardia, pyrexia, hypoxia
Less common:
-Jaundice
-Acute renal failure
-Retroperitoneal hemmorage
-Effusions
-Paralytic ileus
Tests
Blood tests: -amylase test/ lipase is significant - usually 3 times what they should be -Calcium test: when severe- hypocalcemia will be present -LFT: high AST/ALT -FBC: Raised WBC -Low albumin -Hyperglycemia- high glucose EUS: gallstones, pseudocysts ERCP Use Glasgow scoring system
Causes
- Alcohol
- Trauma e.g. post surgery , ERCP
- Gallstones
- Hypertrycidemia
- Miscellaneous e.g. drugs/virus
Risk factors
- middle aged women
- young to middle aged men
Resuscitation
fluids analgesics anti-emetics o2 Nasogastric tube Painkillers when required Catherisation to monitor urine output- monitor kidney output Blood transfusion if Hb low Ca supplement Insulin
Treatment
For necrosis: CT fine needle aspiration, Antibiotics, necrostomy
For Gallstones: cholecystectomy
Potential consequences
- Pseudocysts: cysts which are not confined by serosa
- Necrosis
- abcesses
Definition
Sudden inflammation of the pancreas
Visible signs of retroperitoneal hemmorage?
Severe bruising of the subcutaneous fat
Cullen’s sign: round umbellicus
Grey Turner’s: On top of flanks
Severe vs Mild
Severe:
- organ failure and local problems
- glasgow scoring system of >3
- raised CRP
Glasgow criteria for acute pancreatitis?
Pa02<8 Kpa Age>55 WBC ELEVATED= Neutrophilia Low calcium Impaired renal function: high urea Low albumin Increased glucose Raised AST/ALT and LDH (lactate dehydrogenase)
How do gallstones cause acute pancreatitis?
Raise intra-ductal pressure- prevent flow of digestive enzymes
The smaller gallstones are more dangerous as they can travel further down
Pseudocyst:
- what is it
- How could it be diagnosed?
- Treatment
A fluid collection which does not have epithelial lining
Diagnosis: Persistantly high serum amylase and pain
Treatment: endoscopic drainage if it does not disappear by itself
What other problems can a pseudocyst cause?
- Jaundice
- Infection
- Haemmorage
- Rupture
