Ultrasound of gallbladder stones
Cholelithiasis is mostly primary and pigmented. Some scholars believe that cholesterol stones and mixed stones are also common in gallbladder stones. At present, most scholars believe that gallstones are often related to regional characteristics and dietary habits, and are more common in women. Gallstones are often associated with cholecystitis, which is a causal relationship to each other. If the attack is repeated, the wall of the gallbladder thickens, the gallbladder shrinks, and the gallbladder can be filled with stones.
The examination of the gallbladder must be performed on an empty stomach. The gallbladder should be filled with bile as much as possible. The bile and the stones are in the gallbladder, forming a good contrast. The location, shape, size and number of the gallbladder stones can be clearly observed for correct diagnosis. If the gallbladder shrinks after eating, the contrast of bile is lacking, and stones are often easily missed, so attention should be paid.
In addition to the clinically typical biliary colic caused by gallstones, the diagnosis of gallstones is generally difficult if they do not occur. The typical gallbladder stones on ultrasonography are: a hyperechoic mass in the gallbladder, accompanied by sound shadows behind, and move with the body position. Ultrasonography can detect the number, size and location of stones in the gallbladder, and observe the thickness and smoothness of the gallbladder wall. If the stone is located at the bottom or neck of the gallbladder, and it is difficult to display on ultrasound, the patient can be changed to lie on the left and right sides. When the stone moves in the gallbladder, ultrasound can be easily detected and correctly diagnosed. Many patients with cholecystolithiasis do not have any discomfort and are often found during physical examination. Therefore, during normal physical examination, routine examination of the liver and gallbladder should be carried out, which is conducive to early detection of gallstones.
