Q2. Correct Answer: C
The patient presents with acute gallstone pancreatitis. In patients with gallstone pancreatitis and evidence of cholangitis, ERCP with sphincterotomy and stone extraction should be performed. The patients fever, jaundice, and right upper quadrant pain are sufficient to make the diagnosis of cholangitis. It is too early in the course of the disease to evaluate for pancreatic necrosis. Typically, triglyceride levels above 1,000 mg/dL are required to induce pancreatitis. Finally, while the patient has cholelithiasis, there is no evidence of cholecystitis. Therefore, a HIDA scan is not warranted.
