48-year-old man with epigastric pain and lipase 1480

A 48-year-old man is admitted with 18 hours of severe epigastric pain radiating to the back and persistent vomiting after a weekend of heavy alcohol use. He has no hypotension or confusion. Temperature is 37.8 C, blood pressure is 128/76 mm Hg, pulse is 108/min, and oxygen saturation is 97% on room air. Examination shows epigastric tenderness without rebound. Lipase is 1,480 U/L, hematocrit 49%, BUN 31 mg/dL, creatinine 1.2 mg/dL, AST 62 U/L, ALT 54 U/L, and total bilirubin 0.8 mg/dL. CT is not yet obtained. Which of the following is the most appropriate next step in management?

The Correct Answer

C


Explanation

Clinical Pearl:
Early management of acute pancreatitis centers on prompt isotonic fluid resuscitation, preferably with lactated Ringer solution, plus analgesia and close reassessment. CT, antibiotics, and ERCP are reserved for specific indications rather than routine initial care.


Explanation:
This patient has acute pancreatitis based on classic pain and markedly elevated lipase, and his hemoconcentration and elevated BUN suggest higher risk from intravascular volume depletion, making early IV crystalloid resuscitation the most important immediate step. Current gastroenterology guidance favors lactated Ringer solution over normal saline in many patients because it may lessen acidosis and systemic inflammation, but fluids must be reassessed frequently to avoid overload. Urgent contrast CT is not needed when the diagnosis is already clear and is usually reserved for diagnostic uncertainty, concern for complications, or lack of improvement after the first couple of days. Prophylactic antibiotics do not improve outcomes in uncomplicated pancreatitis and are reserved for documented infection or infected necrosis. ERCP is indicated early when pancreatitis is accompanied by cholangitis or ongoing biliary obstruction, neither of which is supported here by the normal bilirubin and only mild transaminase elevation. Prolonged bowel rest is outdated, as patients should begin oral or enteral feeding once nausea and pain permit rather than waiting for lipase normalization.
