Cholecystitis is usually characterized by abdominal pain, jaundice and fever as the patient’s complaints and should be differentiated from diseases with symptoms presenting with epigastric pain, such as acute pancreatitis, peptic ulcer, appendicitis and intestinal obstruction. The clinical diagnosis of cholecystitis also requires a comprehensive analysis with physical examination, history taking, and relevant laboratory findings and imaging reports to clarify the diagnosis. Acute cholecystitis can first be treated with internal anti-infective therapy, and if the inflammation is caused by stones and the stones are located in the common bile duct or the cystic duct, treatment can be performed by endoscopic or surgical means. Chronic cholecystitis can recur and is more difficult to subside.
