The diagnosis of biliary tract cancer, gallbladder and biliary duct system is divided into two parts. Gallbladder bile of hollow organs is included, and more at the bottom of the right lobe of the gallbladder fossa, pear-shaped, because of its anatomical relationship clear, good interface reflection is an ideal organ ultrasound examination. Clear outline of the normal gallbladder, wall smooth and tidy, anechoic cystic cavity, posterior echo enhancement, showed typical cystic structure. As a store bile, concentrate and remove the physiological function of bile, when the gallbladder emptying, its the liquid, solid interface disappears, ultrasonography also will show is unclear, so the gallbladder ultrasound probe should be fasting 8 hours more to ensure the gallbladder, bile duct filled a good manner
1. Gallbladder benign tumor
Common are gallbladder polyps and gallbladder adenoma. The performance of sonographic gallbladder clear outline, size and shape of the normal, good filling, forming the border more clearly in the gallbladder wall, keyed smooth surface acoustic wave nodules, mostly in diameter, less than lcm, the position does not change with the position.
2. gallbladder
Gallbladder cancer is a malignant tumor with higher levels, most of adenocarcinoma, squamous cell carcinoma occasionally. Cystic tumor in the bottom of the swollen more; gallbladder malignancy was high, with fast growth and early metastasis characteristics. Location close to the liver, gallbladder, often a direct violation of the liver, the portal invasion or metastatic lymph nodes, can cause obstruction of the yellow plague. About 80% of gallbladder cancer with concomitant gallbladder stones.
The diagnosis of biliary tract cancer, gallbladder cancer metastasis first appeared more swollen gallbladder neck lymph nodes, and then can be transferred to the duodenum, and retroperitoneal lymph nodes around, which can be checked with ultrasound.
