Diagnostic basis of gallbladder cancer

What is the diagnosis basis of gallbladder cancer? I believe everyone knows that there is a certain relationship between gallbladder cancer and gallstones. Therefore, it is sometimes difficult for many people to determine whether they have gallbladder cancer. Therefore, at this time, we need some diagnostic basis to make a judgment. Next, let's take a look at what is the diagnosis of gallbladder cancer.

1. The sensitivity of CT scan for gallbladder cancer is 55%, especially for the diagnosis of early gallbladder cancer, which is not as good as US and EUS. CT image changes can be divided into three types: ① Wall thickness type: gallbladder cancer has limited or diffuse irregular thickening of the gallbladder wall. ② Nodular type: papillary nodules protrude from the gallbladder wall into the cavity, and the gallbladder cavity exists. ③ Solid type: gallbladder cancer is a solid mass formed by extensive infiltration and thickening of the tumor and filling of the cavity with cancer. If the gallbladder cancer tumor invades the liver or metastasizes to the liver hilum and pancreatic head lymph nodes, it can often be displayed under CT images.

2. Color Doppler blood flow imaging, which is also one of the diagnostic methods for gallbladder cancer. Domestic literature reports that abnormal high-speed arterial blood flow signals detected in the gallbladder mass and wall are important features that distinguish primary malignant gallbladder cancer from gallbladder metastasis or benign gallbladder masses.

3. Some people report that the diagnosis rate of ERCP for gallbladder cancer that can show the gallbladder can reach 70% to 90%, but more than half of ER-CP examinations cannot show gallbladder cancer. Its imaging manifestations can be divided into three situations: (1) The gallbladder and bile duct are well visualized: mostly early lesions, typical gallbladder cancer patients can see gallbladder filling defects or lesions connected to the cyst wall with a wide base. Infiltration of the gallbladder wall can show stiffness or deformation of the cyst wall. (2) The gallbladder is not visualized: mostly in the middle and late stages. (3) The gallbladder is not visualized and there is hepatic or extrahepatic bile duct stenosis: filling defects and dilatation of the hepatic bile duct above the obstruction are signs of advanced gallbladder cancer.

The above is a detailed description of the diagnostic basis for gallbladder cancer. I hope it can help everyone better understand how to detect whether they have gallbladder cancer.
