Essential Review‑of‑Systems Elements for Acute Pancreatitis

Gastrointestinal Assessment

Record the severity of nausea and vomiting because these symptoms accompany pancreatic inflammation and influence nutritional management. 1
Evaluate for jaundice or dark urine, which indicate biliary obstruction from gallstones—the most frequent cause and one that requires targeted intervention. 2

Quantify alcohol intake in standard units per week; excessive consumption is the second‑most common precipitant after gallstone disease. 2
Inquire about recent viral prodromal illness (fever, myalgias, upper‑respiratory symptoms) to identify possible viral pancreatitis. 2
Review all current medications, as drug‑induced pancreatitis represents a notable subset of cases. 2
Ask about recent abdominal or cardiac surgery because post‑procedural pancreatitis is a recognized complication. 2
Screen for HIV infection, a recognized risk factor for pancreatitis. 2
Document a history of hyperlipidemia or hypercalcemia, metabolic disorders that can trigger pancreatitis. 2
Assess for prior symptoms of gallbladder disease (e.g., right‑upper‑quadrant pain, food intolerance) since cholelithiasis is the leading etiology. 2

Identify signs of volume depletion (e.g., dizziness, reduced urine output, thirst) because third‑spacing of fluid is a major contributor to early mortality. 1
Record baseline urine output; oliguria signals renal dysfunction and predicts severe disease. 2
Screen for chest pain or dyspnea, which may reflect cardiac complications or pleural effusions that develop in severe pancreatitis. 1

Ask about shortness of breath or difficulty breathing, as acute respiratory distress syndrome can develop in severe pancreatitis and is a leading cause of early death. 1
Inquire about cough or pleuritic chest pain, which may indicate pleural effusions or secondary pneumonia. 1

Document fever because it may denote infected pancreatic necrosis, a condition associated with approximately 35 % mortality when combined with organ failure. 1
Assess for confusion or altered mental status, which signals severe disease with multi‑organ dysfunction. 1

Do not accept a superficial alcohol history; precise quantification in units per week is essential because patients often under‑report consumption. 2
Do not overlook a comprehensive medication review; many drugs can cause pancreatitis and this etiology is frequently missed. 2
Do not dismiss mild confusion or slight dyspnea, as these subtle signs may herald severe disease requiring intensive‑care monitoring. 1

The American Gastroenterological Association recommends CT scanning with intravenous contrast as the preferred confirmatory imaging test when diagnosis is uncertain, but it should be delayed until 72 hours after symptom onset to avoid underestimating the extent of pancreatic necrosis 3
Early CT (within 72 hours) is unreliable for assessing necrosis and should be avoided unless there is diagnostic uncertainty 3

Obtain liver chemistries (bilirubin, AST, ALT, alkaline phosphatase) at admission to establish etiology, as elevated aminotransferases or bilirubin suggest gallstone etiology 3, 4
Measure serum calcium level at admission to identify hypercalcemia as a potential cause 3

The American Gastroenterological Association recommends using the APACHE II scoring system with a cutoff of 8 to predict severe disease 3
Patients with APACHE II score >8 or evidence of organ failure during the initial 72 hours require contrast-enhanced CT after 72 hours to assess for pancreatic necrosis 3
C-reactive protein >150 mg/L at 48 hours after disease onset is an adjunctive marker for severe disease 3
Patients with predicted severe disease, actual severe disease, or persistent organ failure should be triaged to an intensive care unit or intermediate care unit 3

Perform abdominal ultrasonography at admission to screen for cholelithiasis or choledocholithiasis 3
Document specific risk factors, including alcohol use quantified in units per week 4, family history of pancreatic disease 3, and history of trauma 3
For patients over age 40 with unexplained pancreatitis, perform CT or EUS to exclude underlying pancreatic malignancy 3
For recurrent unexplained pancreatitis, EUS is preferred as the initial advanced test over ERCP 3

Do not accept "idiopathic" pancreatitis without thorough investigation - etiology should be established in at least 75-80% of cases 3, 4
Avoid early CT (before 72 hours) for severity assessment as it underestimates necrosis 3
Do not perform extensive invasive evaluation in young patients (<40 years) with a single episode of unexplained pancreatitis 3
