What are the diagnoses of cholecystitis
Clinically, chronic cholecystitis is still relatively common, these people need to pay attention to eating less eggs and fatty meat in their daily diet, the diagnosis of chronic cholecystitis requires some examinations to be confirmed, such as ultrasound or X-ray, etc., if you still want to know more about the diagnosis of cholecystitis, let's see what the experts say.
When acute cholecystitis is clinically suspected, the diagnosis can be confirmed by hepatobiliary scintigraphy and ultrasonography. Intravenous injection of iminoacetoacetic acid compounds labeled 99 m technetium can be rapidly taken up and excreted by the liver, and the liver, extrahepatic bile ducts, gallbladder, and duodenum can be visualized sequentially by applying isotope scanning techniques. The clinical diagnosis of acute cholecystitis is often supported by normal liver and bile duct imaging without gallbladder development, with a sensitivity of 97% and specificity of 90%. False positives can occur in total parenteral nutrition (TpN), pancreatitis, critical illness, or fasting. Although ultrasound is a good method for diagnosing cholecystitis, it is not precise enough to diagnose acute cholecystitis, confirming that Murphy's sign on ultrasound, gallbladder wall thickening, and perigallbladder effusion are helpful.
Diagnosis of acute cholecystitis is difficult when the clinical presentation is atypical and must be distinguished from cholangitis, pancreatitis, appendicitis, peptic ulcer and pleurisy. Each of these conditions has its own clinical features, and hepatobiliary scans and ultrasonography can provide reliable evidence for the diagnosis of acute cholecystitis.
CT examination, cholecystitis can generally be diagnosed clinically, and CT examination is only done when complications occur, such as gallbladder perforation, and CT scan shows that there is an abscess with fluid level in the gallbladder fossa. In general, cholecystitis shows thickening of the gallbladder wall, and the gallbladder is mostly enlarged in the acute stage.
If there are air bubbles in the wall on ultrasound examination, the diagnosis of "emphysematous cholecystitis" can be made. Chronic cholecystitis is often associated with stones, which can clearly show positive stones on CT, and negative stones still require a contrasting CT scan (intravenous cholegraglumine or oral iodopanic acid).
The above is the expert's discussion of the diagnosis of cholecystitis. In clinical practice, patients need to be consulted in detail by experts when they see a doctor, because this can not only narrow down the scope of the cause of the disease, but also reduce the patient's suffering. For patients with cholecystitis who are hospitalized, nurses need to do a good job of education in terms of diet.
