The difference between cholecystitis and gallstones is that gallstones are the cause and cholecystitis is the effect, that is, there is cholecystitis only because of gallstones. In clinical practice, most of the causes of cholecystitis are mechanical inflammation caused by damage to the mucous membrane of the gallbladder caused by gallbladder stones or gallbladder polyps, and even induced bacterial infection, so gallstones are the cause and cholecystitis is the effect. Clinically, most patients with gallstones can present with acute or chronic cholecystitis, while very few patients have static stones, i.e. asymptomatic gallbladder stones. For asymptomatic gallstones, they can be closely observed and regularly followed up. Generally, if they last for more than 10 years, they need to be alerted to the possibility of cancerous changes and be treated surgically. In the case of acute cholecystitis, because the local edema is more obvious, symptomatic treatment such as anti-infection and antispasmodic is advocated, and then elective surgery will be performed after the inflammation subsides.
