What is the first line treatment for gallstone pancreatitis without cholangitis or bile duct obstruction?
fluid resuscitation
What else is needed in the management of gallstone pancreatitis without cholangitis or bile duct obstruction?
- analgesia
- Nutritional support, severity assessment
- Cholecystectomy
- Consider: supplemental oxygen, antiemetic, IV antibiotics (if infection suspected), calcium and magnesium replacement therapy

What else is needed in the treatment of gallstone pancreatitis with bile duct obstruction?
- analgesia
- Nutritional support, severity assessment
- ERCP and sphiceteromty
- Consider: supplemental oxygen, antiemetic, IV antibiotics (if infection suspected), calcium and magnesium replacement therapy
What is the first line treatment for alcohol related pancreatitis?
fluid resus
What are other things needed in the treatment of alcohol related pancreatitis?
First line: Fluid resuscitation
- analgesia

- Vitamin replacement + Alcohol abstinence programme
- Consider: supplemental oxygen, antiemetic, IV antibiotics (if infection suspected), calcium and magnesium replacement therapy
What is the first line treatment of ongoing acute pancreatitis deteriorating or failing to improve after 5-7 days?
CECT
What else is needed in the management of ongoing acute pancreatitis deteriorating or failing to improve after 5-7 days?
- Ongoing supportive treatment
- Ongoing nutritional support
- Consider: FNA and culture
What is the first line treatment for infected pancreatic necrosis?
CECT
What else is needed in the management of infected pancreatic necrosis?
- IV antibiotics
- Consider: catheter draining and necrosectomy/debridement
What is the first line treatment of sterile pancreatic necrosis?
CECT
What other things are needed in the management of sterile pancreatic necrosis?
- Ongoing supportive treatment
- Ongoing nutritional support
- Consider: FNA and culture + catheter drainage or necrosectomy
What are the possible complications of acute pancreatitis?
- Acute renal failure
- Pancreatic abscess
- Abdominal compartment syndrome
- Chronic pancreatitis
- Enteric fistulas
- Sepsis
- Acute lung injury / ARDS
- Pseudocyst
- Pancreatic ascites/pleural effusion
What is the prognosis of acute pancreatitis?
- 80% with ap improve within 3 to 7 days of conservative management
- Mortality is 5% but rises to 30% in severe
What drugs can cause acute pancreatitis?
- sodium valproate
- steroids
- thiazides
- azathioprine
What is the defintion for acute pancreatitis?
reversible acute inflammation of pancreases
What is the patho for acute pancreatitis?
- Calcium build up in inflamed pancreas
- Released of enzymes (amylase, lipase, protease)
- Enzymes damage local structures and cause systemic symptoms and signs
What are the symptoms of hypovolaemia that may be present in acute pancreatitis?
- hypotension
- tachycardia
- sweating
- decreased skin turgor
What signs are present in acute pancreatitis?
- Cullen’s – periumbilical brusing
2. Grey/Turners: flank brusing
What is the preferred imaging for acute pancreatitis?
CT abdo
What score is used for serverity of acute pancreatitis?
Modified Glasgow/PANCREAS SCORE
What is involved in the PANCREAS socre?
- PaO2<8kPa(60mmHg)
- Age >55
- Neutrophils WBC >15x10^9/L
- Calcium <2mmol/L
- Renal function: Urea >16mmol/L
- Enzymes AST/ALT>200 iu/L or LDH >600iu/L
- Albumin <32g/l
- Sugar: glucose >10mmol/L
What is the general Tx for acute pancreatitis?
- Analgesia
- IV fluids and electrolytes
- Oxygen support
- NG tube
- Control blood sugar
- ABx if infected necrotic tissue
How do you treat gallstones if that is the cause of the AP?
ERCP (with sphincterotomy), cholecystectomy
How do you treat necrotic tissue if that is the cause of the AP?
necresectomy
How is ERCP peformed?
- to relieve biliary obstruction, with or without sphincterotomy (stent placement) to dilate the sphincter of Oddi
- allows ductal stones to be removed, biliary sludge to be cleared, and relief of the obstructed biliary tree driving pancreatitis
What is the prognosis of acute pancreatitis?
20% of having Tx and still dying, haematocrit is a predictor of severity
