When can bile duct cancer be detected? Experts say that in the early stages of bile duct cancer, the disease can be detected, so when symptoms such as abdominal pain, indigestion, fever, jaundice, etc. appear, you need to seek medical attention in time to strive for early diagnosis and early treatment. The following is an introduction to the various inspection methods for you. 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 examinations 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 a mass or cord-like, hilar cancer often presents as a cord-like, and lower bile duct cancer often presents as a protruding type. 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 94% to 100%. 4. CT: The basic manifestation of cholangiocarcinoma on CT is the obvious dilatation of the proximal bile duct. The bile duct wall close to the tumor is thickened, and the bile duct is more clearly enhanced during enhanced scanning, and the lumen is irregularly narrowed and deformed. Generally, a tumor shadow with soft tissue density can be found, and its CT value is 50Hu, and the enhanced CT value during enhanced scanning is 60-80Hu. Most tumors grow infiltratingly along the bile duct wall. The bile duct wall is thickened, and the edges are unclear. They can be enhanced and easily displayed during enhanced scanning. A few grow into the lumen in a polyp-like or nodular shape, and the nodules are soft tissue density. The tumor infiltrates and expands into the cavity, with blurred edges of the tube wall. It often invades the gallbladder, liver, adjacent blood vessels and lymphatic tissues. It presents a non-uniform density soft tissue shadow with irregular shapes, blurred tissue structure and unclear boundaries. 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 to directly observe and clamp the mass for biopsy. When performing PTC or PTCD, bile can be extracted for cytological examination. Early treatment of bile duct cancer is very important, but early abdominal pain and bloating are often ignored. Do you know all of this now? When there is a problem, you must go to the hospital for a check-up. The above examination items are all for confirming bile duct cancer. Learn more about them. |
