Firstly, it is necessary to determine the cause of the cholecystitis. The most common type of cholecystitis is caused by gallstones. If the cholecystitis is an acute episode caused by gallstones, leading to pain, nausea, vomiting, or even high fever, surgical intervention is usually indicated. It is generally recommended to consult with departments such as general surgery or hepatobiliary surgery, as emergency surgery may be needed. The second scenario involves cases where cholecystitis is detected during routine physical examinations without symptoms. Ultrasound may show gallstones or gallbladder polyps. In symptom-free situations, it is possible to consult general departments like gastroenterology, and regular follow-ups and checks of inflammation indicators, as well as abdominal ultrasonography, can be performed to monitor the dynamic changes of the cholecystitis. The third scenario pertains to cholecystitis where new techniques such as MRCP are available. With this technology, gallstones can be removed under endoscopic guidance. Generally, these procedures are performed in the gastroenterology department. Thus, for acute cholecystitis with choledocholithiasis and concurrent biliary pancreatitis, it may be treated with endoscopic techniques under gastroenterology, avoiding the need for traditional or minimally invasive surgery. Therefore, patients with cholecystitis may visit either the hepatobiliary surgery or gastroenterology departments.
