1, laboratory tests Gallbladder stones usually do not appear jaundice and liver dysfunction, laboratory tests of liver function mostly have no positive test results, but sometimes jaundice can be found, which is helpful to trace the cause of the disease. 2.Other auxiliary examinations Imaging is the main means to confirm the diagnosis of gallbladder stone disease, ultrasound is often the first line of examination, which can detect stones in the gallbladder, gallbladder wall thickening, lack of contraction of the gallbladder, and the results are often accurate and reliable. The positivity rate is extremely high, and it is a simple, economical, non-invasive test that is widely used in clinical practice. On X-ray plain films, due to the low positive rate of stones, X-ray plain films of the hepatobiliary region are no longer required for clinical diagnosis. About 20% of gallbladder stones may show positive images due to their high calcium content. However, radiographs may show soft tissue shadows of enlarged gallbladder and inflammatory masses as well as gas shadows in and around the gallbladder in cases of pneumatobiliary cholecystitis. Reflex intestinal stasis such as dilatation and inflation of the small intestine below the gallbladder, blurring or disappearance of the peritoneal fat line on the right side, elevation of the diaphragm on the right side, some indirect X-ray signs, often help in the diagnosis of acute cholecystitis 3. Oral method cholangiography can show the negative shadow of stones in the gallbladder, and the accuracy rate is up to 95% when the gallbladder duct is patent and the concentrated function of the gallbladder is still good. Negative shadow. 4. The thick gallbladder wall with stones in the cyst and inflammatory changes around the gallbladder wall are seen on CT images. Enhanced CT scan examination can increase the resolution of stones. 5.MRCP is good for the judgment of gallbladder stones and cholecystitis, and the direction and variation of the gallbladder duct and extrahepatic bile duct can be observed, so preoperative examination is very necessary.
