Cholecystitis is divided into acute cholecystitis and chronic cholecystitis. Acute cholecystitis typically presents very typical and obvious clinical symptoms, primarily manifesting as acute abdominal pain. Acute cholecystitis often occurs after eating greasy food, mainly presenting as severe colicky pain in the upper right abdomen, which is episodic and worsens. The pain may radiate to the right shoulder or back, followed by nausea, vomiting, and in severe cases, fever. Some severe cases may also present with jaundice and symptoms of systemic infection and toxicity. Acute simple cholecystitis is often treated non-surgically, and most cases can be cured. If the patient has a history of multiple attacks or the presence of stones, elective cholecystectomy is usually performed later. For suppurative or gangrenous cholecystitis, surgery should be performed promptly after appropriate preparation to remove the diseased gallbladder, typically within three days of onset. If the patient's condition is critical at the time of surgery, or if there is severe local infection and the anatomy is unclear, the doctor will not forcibly remove the gallbladder to avoid major bleeding and damage. Instead, a cholecystostomy may be performed first, followed by cholecystectomy after three months. Chronic cholecystitis, besides occasional upper abdominal discomfort and indigestion, usually shows no prominent symptoms, and most patients only learn about their condition through ultrasound examination. However, for recurrent acute attacks or symptomatic chronic cholecystitis, especially those with stones larger than 1 cm or multiple stones, cholecystectomy should be performed. Elderly or frail individuals with other serious illnesses, such as cardiovascular disease, diabetes, kidney disease, or liver disease, may receive medical treatment, including general digestive aids and antispasmodic medications. Bile preparations have choleretic effects, can increase the secretion of bile, promote the digestion and absorption of fats, and facilitate the excretion from the gallbladder, which can alleviate symptoms and stabilize the condition. Considering that acute attacks of chronic cholecystitis in elderly people progress rapidly and that emergency surgery has a much higher mortality rate than elective surgery, it is advisable to perform surgery during a remission period. Whether treated with medication or surgery, it is important to follow medical advice.
