The location of abdominal pain in pancreatitis is mainly in the upper abdomen or around the navel, usually with a transverse distribution, which is different from the pain of cholecystitis or gastritis. The pain is very pronounced and knife-like, accompanied by abdominal distension, nausea, vomiting, anal cessation and defecation. If the patient is very ill, he or she may experience pain in the back and may develop skin petechiae, such as petechiae around the belly button or in the upper abdomen. If the condition allows, it is recommended to do abdominal enhancement CT to further clarify whether the pancreatic gland is necrotic, that is, to clarify whether it is severe pancreatitis or mild pancreatitis, which is an important guidance for the next treatment.
