The clinical manifestations of acute pancreatitis generally present as upper abdominal pain, with some patients also experiencing fever, nausea, vomiting, and pain in the lumbar and back areas. In terms of physical signs, the main ones are abdominal distension and tenderness in the upper abdomen, with abdominal pain being the most commonly seen symptom in clinical settings. This pain is typically in the upper abdomen, persistent, and difficult to alleviate, although bending forward may provide some relief for the patient; some patients may also experience symptoms of vomiting. Diagnosis of the condition primarily relies on blood and urine amylase levels and imaging studies. Typically, an ultrasound and CT scan of the abdomen are completed, which can reveal typical changes associated with acute pancreatitis, such as effusion, etc. Treatment, for now, involves enzyme inhibition, fasting, acid suppression, fluid replacement, and other symptomatic treatments. Generally, the acute phase of pancreatitis can be controlled within five to seven days, but if severe pancreatitis is considered, the treatment period may be longer. (The use of medication should be under the guidance of a physician.)
