Patient will present as → a 37-year-old male complaining of rapid onset of severe mid-epigastric pain with radiation to the back after eating a large meal. The pain typically lessens when the patient leans forward or lies in the fetal position. Physical exam shows low-grade fever, epigastric tenderness, diminished bowel sounds, and bruising of the flanks. An abdominal CT scan shows localized dilation of the upper duodenum and a small collection of fluid in the left pleural cavity.

Acute Pancreatitis - epigastric abdominal pain with radiation to the back and elevated lipase - pain decreases when the patient leans forward

• It has many causes, including gallstones and chronic, heavy alcohol use
  • The mnemonic GET SMASHHED is useful in recalling the most common causes:
    • Gallstones, Ethanol, Trauma, Steroids, Mumps, Autoimmune disease, Scorpion sting, Hypercalcemia, Hyperlipidemia, ERCP and Drugs
• Cullen's sign (bruising near the umbilicus) is superficial edema and bruising in the subcutaneous fatty tissue around the umbilicus.
• Grey Turner's sign (flank bruising) refers to bruising of the flanks, the part of the body between the last rib and the top of the hip

This 40-year-old woman complained of worsening epigastric pain of five days duration. On examination, she had hypotension, a board-like abdomen, and extensive ecchymosis over her right loin (Grey Turner’s sign)

Acute pancreatitis with Cullen’s sign

Ranson’s criteria for poor prognosis

Ranson's criteria: The Ranson criteria form a clinical prediction rule for predicting the severity of acute pancreatitis.  Three or more means a more severe course:

Chronic Pancreatitis

Clinical features are the same as those of acute pancreatitis, with the addition of fat malabsorption and steatorrhea late in the disease. Fecal fat will be elevated if malabsorption is present.

The classic triad (look for this on your exam) of pancreatic calcification, steatorrhea, and diabetes mellitus occurs in only 20% of patients

• Permanent and progressive damage to the pancreas
• Epigastric abdominal pain, weight loss, diarrhea, and pancreatic pseudocyst (a circumscribed collection of fluid rich in pancreatic enzymes, blood, and necrotic tissue)

Will have prandial epigastric pain. Labs will show increased serum lipase (more sensitive and specific than amylase, but only with elevations of threefold or greater)

• An abdominal CT scan is the diagnostic test of choice
• Sentinel loops on X-Ray
  • look for diminished bowel sounds as part of the exam question
• A CT scan using a pancreatic protocol or MRI with magnetic resonance cholangiopancreatography (MRCP) are the best initial diagnostic tests for chronic pancreatitis

A CT scan of exudative tail pancreatitis, characterized by fluid accumulation in the fatty tissue around the pancreatic tail.

The mainstay of treatment for acute pancreatitis is supportive therapy: IV fluid resuscitation, pain control, and nutritional support

• Antibiotics for extrapancreatic infections and infected necrosis
• Endoscopic retrograde cholangiopancreatography (ERCP) for acute pancreatitis and concurrent acute cholangitis
• Complication: pancreatic pseudocyst (a circumscribed collection of fluid rich in pancreatic enzymes, blood, and necrotic tissue)
• Patients with mild pancreatitis can progress to severe pancreatitis over the initial 48 hours, often due to inadequate fluid replacement
• Referral to a tertiary center is needed if acute pancreatitis is severe or evolving/worsening

The only definitive treatment for chronic pancreatitis is to address the underlying cause, which is most commonly alcohol, low-fat diet
