The diagnostic method of choice for cholelithiasis

The diagnostic test of choice for cholelithiasis is abdominal ultrasound. For patients with suspected cholelithiasis, ultrasound is a non-invasive, radiation-free, easy-to-use, and cost-effective diagnostic tool that can accurately detect stones in the gallbladder.

Cholelithiasis refers to the formation of stones in the gallbladder or bile ducts. Common symptoms include right upper abdominal pain, nausea and vomiting, and when the stones block the bile ducts, jaundice may also occur. There are many reasons for the formation of gallstones, among which abnormal cholesterol metabolism, bile stasis and chronic gallbladder inflammation are the main risk factors. Irregular diet, obesity, rapid weight loss and certain medications may also promote the formation of gallstones.

Ultrasound uses sound waves to create an image of the gallbladder. This technique is very effective in showing the location and number of stones. If ultrasound shows gallstones and the person has significant symptoms, further evaluation is usually needed to decide whether to treat. Occasionally, the doctor may choose to do a CT scan or magnetic resonance imaging (MRI) to get a more detailed picture of the condition. Laboratory tests such as liver function tests may also be ordered to evaluate for complications.

For patients with cholelithiasis who do not have symptoms, immediate treatment is usually not needed and only regular observation is required. However, patients who develop severe symptoms or complications, such as cholecystitis, bile duct obstruction, or pancreatitis, may require surgery to remove the gallbladder. In daily life, maintaining a healthy diet and moderate exercise can help reduce the risk of gallstones. In the face of persistent or worsening abdominal discomfort, it is recommended to seek professional medical help for comprehensive evaluation and treatment.
