Diagnosis and differential diagnosis of cholelithiasis

The diagnosis of cholelithiasis not only relies on modern medical imaging technology, but also needs to be combined with the patient's clinical symptoms and signs. Cholelithiasis, as the name suggests, refers to the appearance of stones in the gallbladder or bile duct. In most cases, these stones are formed due to the deposition of cholesterol in the gallbladder.

To understand cholelithiasis, we need to know the role of bile. Bile is produced by the liver and helps digest and absorb fat. When the cholesterol content in bile is too high or the gallbladder is blocked from emptying, stones may form. People with cholelithiasis may usually experience dull pain in the upper abdomen, especially after consuming a high-fat meal. Sometimes it is accompanied by symptoms such as nausea and vomiting, and in some severe cases, it can even cause acute cholecystitis or cholangitis.

The diagnosis of cholelithiasis relies mainly on ultrasound, which is highly accurate and safe for patients. CT and MRI can also provide further details, especially when it is judged that the stones may cause bile duct obstruction. Laboratory tests can help identify any signs of inflammation or infection. In terms of differential diagnosis, we also need to rule out other diseases that may cause similar symptoms, such as pancreatitis, gastric ulcers, or liver-related diseases.

In order to better manage cholelithiasis, patients should consider dietary control, avoid high-fat, high-cholesterol foods, and consume more fiber. Maintaining a regular schedule and exercising moderately in daily life can help improve bile metabolism. If symptoms persist or worsen, it is recommended to seek medical attention in time and have a detailed evaluation by a professional doctor to determine the best treatment plan. This can not only relieve symptoms, but also prevent possible complications, which is an effective guarantee for one's own health.
