A patient with heavy alcohol use presents with severe midepigastric pain radiating to the back and fever; WBC elevated and amylase elevated. The most likely diagnosis is?

• A. Perforated duodenal ulcer
• B. Acute pancreatitis
• C. Acute cholecystitis
• D. Mesenteric ischemia

Answer: (B)

Pain in the midepigastric region that radiates to the back, coupled with heavy alcohol use and an elevated pancreatic enzyme, points to acute pancreatitis. Alcohol is a common trigger because it damages the pancreatic cells and promotes premature activation of digestive enzymes, leading to autodigestion and inflammation. The classic pain pattern—epigastric or abdominal pain that radiates to the back—along with fever and leukocytosis reflects the inflammatory response the pancreas can provoke. While amylase (and lipase) elevation supports the diagnosis, lipase is more specific for pancreatitis; amylase can rise in other conditions, but in this clinical context it strongly reinforces pancreatitis. Perforated duodenal ulcer would typically cause sudden, severe abdominal pain with signs of peritonitis and often free air on imaging, rather than the pancreatic pain pattern described. Acute cholecystitis usually presents with right upper quadrant pain and a positive Murphy sign, and while amylase can be mildly elevated, the pain location and typical triggers differ. Mesenteric ischemia presents with severe pain out of proportion to exam and usually affects patients with vascular risk factors, not primarily from alcohol use, and the lab pattern is not as characteristic of pancreatitis. So the combination of risk factor, pain distribution, and pancreatic enzyme elevation makes acute pancreatitis the most likely diagnosis.
