cholangiectasis是什么意思,cholangiectasis翻译
Cholangiectasis, also known as biliary atresia, is a condition characterized by the blockage of the bile ducts, which prevents bile from flowing properly from the liver to the intestines. This blockage leads to a buildup of bile in the liver, causing inflammation and damage to the liver cells. Over time, this can lead to serious liver disease and other complications.
There are several different types of cholangiectasis, depending on the cause and the extent of the blockage. The most common type is primary biliary cirrhosis, which is an autoimmune disorder that causes the immune system to attack the bile ducts. This results in inflammation and scarring of the ducts, eventually leading to blockages. Other types of cholangiectasis include secondary biliary cirrhosis, which is caused by conditions such as pancreatitis or parasitic infections, and congenital cholangiectasis, which is present at birth.
The symptoms of cholangiectasis can vary depending on the severity of the condition, but common symptoms include abdominal pain, dark urine, jaundice (yellowing of the skin and eyes), and itching. In severe cases, patients may also experience fatigue, weight loss, and swelling of the legs and abdomen. In some cases, cholangiectasis can lead to serious complications, such as liver failure or cancer.
Diagnosis of cholangiectasis typically involves a combination of medical history, physical examination, and various tests. Blood tests can measure levels of certain enzymes that are elevated when the liver is damaged, and imaging tests such as ultrasound, CT scan, or MRI can be used to visualize the bile ducts and assess for blockages. In some cases, a liver biopsy may be necessary to confirm the diagnosis.
Treatment for cholangiectasis depends on the underlying cause and the severity of the condition. In some cases, the blockage can be removed surgically, which may require a liver transplant in severe cases. Medications can be used to control symptoms and manage complications, and in some cases, a procedure called endoscopic retrograde cholangiopancreatography (ERCP) can be used to clear blockages.
