Pancreatitis is often differentiated from mild to moderate by blood pressure status, clinical signs, laboratory tests, and imaging findings. Pancreatitis can be divided into mild edematous and severe necrotizing pancreatitis. Mild simple edematous pancreatitis often has mild clinical symptoms, and patients usually have a fever of no more than 38°, with the main CT manifestation being edema of the pancreas combined with peripheral oozing. The mainstay of treatment is water fasting and symptomatic therapy. Severe necrotizing pancreatitis clinical symptoms are more serious, the patient is obviously high fever, abdominal pain, rebound pain, abdominal muscle tension and other signs of peritonitis; laboratory examination of the patient’s blood calcium is significantly reduced, blood glucose continues to rise; imaging CT will find a large area of necrosis of the pancreas. Suspicion of pancreatitis, need to go to the hospital in a timely manner, clear diagnosis and treatment options, under the guidance of the doctor to use drugs, avoid self-medication.
