What review of systems (ROS) should be performed in a patient with suspected acute pancreatitis?

Review of Systems for Acute Pancreatitis

When evaluating a patient with suspected acute pancreatitis, perform a targeted review of systems focused on identifying the underlying etiology, assessing disease severity, and detecting organ dysfunction that impacts mortality.

Gastrointestinal System Assessment

• Document the character, location, and radiation of abdominal pain, specifically asking about epigastric pain radiating to the back, as this is the hallmark presentation 1, 2
• Quantify nausea and vomiting severity, as these symptoms accompany the inflammatory process and affect nutritional management 3
• Assess for jaundice or dark urine, which suggests biliary obstruction from gallstones—the most common etiology requiring specific intervention 4, 5
• Inquire about changes in stool color (clay-colored stools suggest biliary obstruction) 5

Etiological Risk Factor Assessment

• Quantify alcohol consumption precisely in units per week, as excessive alcohol use is the second most common cause after gallstones 4, 1
• Ask about recent viral prodromal illness (fever, myalgias, upper respiratory symptoms) to identify viral etiologies 4
• Document all medications, as drug-induced pancreatitis accounts for a subset of cases 4
• Inquire about recent abdominal or cardiac surgery, as post-procedural pancreatitis is a recognized complication 4
• Ask about history of trauma to the abdomen 1
• Obtain family history of pancreatic disease, particularly in younger patients where hereditary pancreatitis should be considered 1

Cardiovascular and Renal Systems

• Assess for symptoms of volume depletion (dizziness, decreased urine output, thirst), as third-spacing of fluid is a major cause of early mortality 3
• Screen for chest pain or dyspnea, which may indicate cardiac complications or pleural effusions that develop in severe disease 3
• Document baseline urine output, as oliguria signals organ failure and predicts severe disease 4

Respiratory System

• Ask about shortness of breath or difficulty breathing, as acute respiratory distress syndrome develops in severe pancreatitis and is a major cause of early mortality 3
• Inquire about cough or pleuritic chest pain, which may indicate pleural effusions or pneumonia 3

Comorbidity Assessment

• Screen for HIV infection status, as this is a recognized risk factor for pancreatitis 4
• Document history of hyperlipidemia or hypercalcemia, as these metabolic disorders cause pancreatitis 4, 1
• Assess for symptoms of gallbladder disease (prior episodes of right upper quadrant pain, food intolerance), as cholelithiasis is the leading cause 4, 5

Constitutional Symptoms

• Document fever, as this may indicate infected pancreatic necrosis, which carries 35% mortality when combined with organ failure 3
• Assess for confusion or altered mental status, which signals severe disease with organ dysfunction 3

Common Pitfalls to Avoid

• Do not accept a superficial alcohol history—quantify precisely in units per week, as patients often underreport consumption 4, 1
• Do not overlook medication review—many drugs cause pancreatitis and this etiology is frequently missed 4
• Do not fail to ask about prior similar episodes, as recurrent pancreatitis requires more extensive etiological investigation including EUS to exclude occult causes 1, 6
• Do not dismiss vague symptoms of organ dysfunction (mild confusion, slight dyspnea)—these herald severe disease requiring ICU-level monitoring 3, 1
