Cholecystitis or/with cholelithiasis: liver and gallbladder are the words we all talk about, the reason for this is because the two have an inseparable connection. Whether systemic infections or local lesions of germs through bloodstream, lymphatic, biliary tract, intestinal tract, or the spread of inflammation in neighboring organs, the invasion of parasites and the bacteria they bring in are important causes of cholecystitis. In some patients with abnormal liver function, cholecystitis or cholelithiasis is characterized by persistent jaundice or recurrent jaundice, often accompanied by symptoms of cholecystitis. Surgical treatment is recommended for these patients. Indications: Emergency surgery should be performed in the acute phase if there are obvious signs of systemic toxicity, peritoneal irritation and deepening jaundice. For patients with long history, recurrent episodes, and obvious organic lesions in the biliary tract, such as calculous cholecystitis, large common bile duct stones and primary bile duct stones, intrahepatic stones with severe symptoms, recurrent bile duct stones with marked dilatation of the common bile duct (hepatic) and biliary tract infection combined with Oddi sphincter stenosis, elective surgery should be performed after acute symptoms are controlled.
