I GET SMASHED

What is I GET SMASHED?

I GET SMASHED is a mnemonic that helps remember the major causes of acute pancreatitis. Acute pancreatitis is inflammation of the pancreas that happens when digestive enzymes become activated too early and begin damaging pancreatic tissue. Gallstones cause about 40% to 70% of cases. Ethanol, or alcohol, is the second most common cause and accounts for about 25% to 35% of cases in Western populations. Recognizing the cause helps guide treatment and prevent recurrence.

What are the causes of acute pancreatitis included in I GET SMASHED?

The causes in I GET SMASHED can lead to pancreatitis through pancreatic duct blockage, direct pancreatic injury, or abnormal activation of digestive enzymes. Gallstones can block the ducts that drain the pancreas. Metabolic problems, such as hypercalcemia and hypertriglyceridemia, can directly injure pancreatic cells. Medications, trauma, and autoimmune disease can also trigger inflammation. These processes can lead to early enzyme activation inside the pancreas rather than in the small intestine. In severe cases, inflammation can progress to necrotizing pancreatitis.

The individual components of the mnemonic include:

• I: Idiopathic, meaning no clear cause is found.
• G: Gallstones and genetic factors, such as cystic fibrosis.
• E: Ethanol.
• T: Trauma, especially blunt abdominal injury.
• S: Steroid use.
• M: Mumps and other infections; rarely, malignancy causing duct obstruction.
• A: Autoimmune disease.
• S: Scorpion stings.
• H: Hypertriglyceridemia, hypercalcemia, or hyperparathyroidism.
• E: ERCP.
• D: Medications, such as azathioprine, thiazides, valproic acid, or tetracyclines.

What symptoms are associated with acute pancreatitis?

Acute pancreatitis usually causes severe upper abdominal pain that may radiate to the back. Nausea, vomiting, and loss of appetite are also common, and symptoms may worsen after eating. tachycardia, fever, and abdominal tenderness can occur when inflammation affects the whole body. Rarely, bleeding around the pancreas can cause bruising around the belly button or along the flanks, known as the Cullen sign or Grey Turner sign.

Clinicians also consider pancreatic cancer symptoms when symptoms are persistent, recurrent, or unusual, especially in older adults. Less commonly, pancreatic cancer ductal obstruction can cause pancreatitis or pancreatitis-like symptoms. Concerning features include painless obstructive jaundice, weight loss, new-onset diabetes, and other signs of pancreatic cancer.

How is acute pancreatitis diagnosed?

Diagnosis usually requires at least 2 of 3 findings: typical abdominal pain, serum amylase and/or lipase levels more than 3 times the upper limit of normal, or imaging findings consistent with acute pancreatitis. Lipase is generally preferred because it is more useful for diagnosing acute pancreatitis. A transabdominal ultrasound is commonly used to look for gallstones. Blood tests may also check triglyceride and calcium levels to identify hypertriglyceridemia or hypercalcemia. Contrast-enhanced CT may be used when the diagnosis is unclear, symptoms are severe, or the patient does not improve after 48-72 hours.

How is acute pancreatitis treated?

Treatment focuses on supportive care and treating the underlying cause. Intravenous fluids are usually given early, often with lactated Ringer solution when appropriate. Pain control and early feeding are also important. If the person cannot eat by mouth, enteral nutrition is preferred over intravenous nutrition.

For gallstone pancreatitis, ERCP is used when there is cholangitis or persistent bile duct blockage. Gallbladder removal is usually recommended during the same hospital stay for mild gallstone pancreatitis to reduce the risk of recurrence. In severe hypertriglyceridemia-related pancreatitis, insulin may be used in selected cases to help lower triglyceride levels. If pancreatic necrosis becomes infected, antibiotics and delayed drainage may be needed.

What are the most important facts to know about I GET SMASHED?

• I GET SMASHED organizes the major causes of acute pancreatitis.
• Gallstones and ethanol account for most cases, while idiopathic, metabolic, medication-related, infectious, traumatic, and autoimmune causes account for many of the rest.
• Common symptoms include severe upper abdominal pain, nausea, and vomiting.
• Diagnosis usually depends on typical pain, elevated lipase or serum amylase, and imaging when needed.
• Treatment centers on early fluids, pain control, early feeding or enteral nutrition, and treating the specific cause, such as gallstone pancreatitis, cholangitis, or severe hypertriglyceridemia.
