A brief discussion on how to diagnose pancreatic cancer

In recent years, pancreatic cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of pancreatic cancer, we humans should master the following examination methods for pancreatic cancer:

1. Ultrasound examination is the key to diagnosing pancreatic cancer.

Preferred method and screening method in general survey. During the examination, attention should be paid to the size of the pancreatic head. For example, if the thickness of the pancreatic head measured by ultrasound is greater than 30mm (the ultrasound value of the pancreatic head of most men is less than 30mm and that of women is less than 28mm), and the thickness of the pancreatic body is greater than 25mm (normal men are less than 22mm and women are less than 20mm), further follow-up examinations should be performed. Low-echo solid mass and irregular shape of the pancreatic body can be found. Tumors larger than 2cm can also be found. Dilatation of the pancreatic duct, dilatation of the bile duct (intrahepatic or/and extrahepatic), enlargement of the gallbladder, and intrahepatic metastases can be found. The positive rate for pancreatic cancer of about 3cm can reach

2. Ultrasonic examination with fiberscope: An ultrasonic probe is installed on the top of the gastroscope, close to the posterior wall of the stomach, to conduct a comprehensive examination of the pancreas without interference from gas. This greatly improves the diagnosis rate of pancreatic cancer and can clearly show the pancreatic structure and detect early lesions.

3. CT examination CT scan can show the correct location and size of pancreatic tumors and their relationship with surrounding blood vessels, and can detect tumors with a diameter of about 1 cm. If the scan can be enhanced or some lesions that are difficult to identify with plain scans can be displayed more clearly, low-density irregular lesions can be seen in the enhanced pancreatic parenchyma. This examination can be used for staging to help determine the surgical method and prognosis. Currently, CT has become the main method for diagnosing pancreatic cancer. The accuracy of CT in diagnosing pancreatic cancer can reach

4. Magnetic resonance imaging (MRI) can show abnormal pancreatic contours. The signal level of T1-weighted images can be used to determine early local invasion and metastasis. MRI is superior to CT scan in determining pancreatic cancer, especially small pancreatic cancer confined to the pancreas, and whether there is peripancreatic spread and vascular invasion. It is a better method for predicting pancreatic cancer before surgery.

5. Endoscopic retrograde cholangiopancreatography (ERCP) has a high specificity for the diagnosis of pancreatic cancer. In addition to showing the filling defect and occlusion of the main pancreatic duct, it can also clearly observe the morphological changes of pancreatic duct stenosis. It can detect pancreatic duct lesions with tumors less than 2 cm and is an effective method for diagnosing small pancreatic cancer.

6. Selective angiography (SAG) SAG is a lesion examination, but it can be diagnosed when the tumor is 1 cm. It can show the morphology of the arteries around the pancreas, which is important for judging whether the tumor has vascular invasion, such as irregular arterial stenosis and occlusion. The size of the tumor can be estimated based on the abnormal vascular area. The possibility of tumor surgery and the choice of surgical method can also be determined based on SAG findings. It is very important to determine whether the tumor can be removed by surgery. The presence of blocked artery infiltration is very important. It is used when the usual imaging results cannot make a clear diagnosis. The accuracy rate is higher than

The above is the examination method for pancreatic cancer. Expert Tip: If you have symptoms of disease, do not delay diagnosis and go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
