This document discusses acute pancreatitis, including its etiology, pathogenesis, clinical manifestations, diagnosis, and treatment. It defines acute pancreatitis as inflammation of the pancreas induced by the activation of pancreatic enzymes from various causes. The main causes are biliary diseases, alcohol use, hyperlipidemia, and certain drugs. Clinical features include abdominal pain, nausea, vomiting, and fever. Diagnosis is based on symptoms, elevated serum amylase, and imaging findings. Treatment differs between mild and severe acute pancreatitis and focuses on supportive care, pain management, inhibiting pancreatic enzymes, preventing infections and organ failure.
