Q. A 50-year-old man with a history of chronic alcohol use presents to the emergency department with severe abdominal pain radiating to the back, nausea, and vomiting. The pain is constant sharp and has worsened over the past two days. He appears in distress and is diaphoretic. Physical examination reveals a distended abdomen, with diffuse tenderness and hypoactive bowel sounds. His blood pressure is 90/60 mmHg, heart rate is 110 bpm, and temperature is 38.3°C (100.9°F). Laboratory tests show elevated lipase and amylase levels, increased inflammatory markers, and altered liver function tests. An abdominal CT scan indicates pancreatic swelling and peripancreatic fluid. What would be the primary treatment for this patient’s condition?
