What are the auxiliary examination methods for bile duct cancer

Life is always changing. No one knows what will happen in the next second, and it always takes courage to face it all. Disease is an experience that no one wants to accept, but many people have to go through it. Biliary duct cancer is one of them. So, what are the auxiliary examination methods for bile duct cancer? Next, let's learn about it.

Biliary duct cancer often presents with adverse symptoms such as abdominal pain and bloating. At this time, the patient will go to the hospital for examination. The doctor will determine whether it is bile duct cancer based on the physical symptoms, but the following auxiliary examinations are often required to scientifically determine the condition.

1. Laboratory examination: The main manifestations are abnormal liver function of obstructive jaundice, such as increased bilirubin and alkaline phosphatase.

2. Ultrasound examination: Repeated and careful ultrasound examination can show dilated bile ducts, obstructed sites, and even tumors. The ultrasound images of bile duct cancer can be mass-like, cord-like, protruding, and thrombus-like. Intrahepatic bile duct cancer often presents as mass or cord-like, hilar cancer often presents as cord-like, and lower bile duct cancer often presents as protruding. Thrombotic images of the hilar region may be hilar cancer, gallbladder cancer, or metastatic cancer. Since bile duct dilatation occurs before jaundice, ultrasound has the value of diagnosing early bile duct cancer.

3.PTC: It is the main method for diagnosing bile duct cancer. It can show the location and range of bile duct cancer, and the diagnosis rate can reach more than 90%.

4. CT: The basic manifestation of cholangiocarcinoma on CT is that the proximal bile duct is significantly dilated. The bile duct wall close to the tumor is thickened, and the bile duct is clearer and can be enhanced during enhanced scanning. The lumen is irregularly narrowed and deformed, and most tumors grow infiltratingly along the bile duct wall.

5.ERCP: The duodenal papilla can be directly observed, and the angiography can show the obstructed distal bile duct.

6. Angiography: Angiography can better determine whether bile duct cancer can be removed.

7. Cytological examination: On the basis of PTCD, the sinus tract is enlarged and a fiber choledochoscope is inserted, which can directly observe and clamp the mass for biopsy. When performing PTC or PTCD, bile can be extracted for cytological examination.

Therefore, when you find yourself having abdominal pain, bloating and other adverse symptoms, you must go to a regular hospital for examination in time. Let the doctor give you a physical examination, and then use the above-mentioned auxiliary examinations to determine the condition. Only after the scientific examination method has determined the condition can you use medication reasonably to restore the condition in time.
