Gallbladder Ultrasound

Ultrasound examination of the gallbladder uses B-ultrasound to examine the gallbladder of the patient. It is often used to diagnose gallbladder and biliary tract diseases. It can also be used for acute cholecystitis without abdominal surgery under the guidance of B-ultrasound. This is a medical examination item that patients often come into contact with at the time of treatment. Indications cystic stones, extrahepatic bile duct stones, intrahepatic bile duct stones, acute and chronic cholecystitis, gallbladder polyps, gallbladder cancer, jaundice. Basic Information Specialist classification: Digestive examination classification: ultrasound Applicable gender: whether men and women apply fasting: fasting Tips: Food must be banned for more than 8 hours. Normal value Typical normal gallbladder shape, such as pear, smooth and smooth gallbladder wall, strong reflection, gallbladder cavity is silent zone, strong echo of posterior wall, strong hepatic common duct and proximal common bile duct are parallel distributed before portal vein, gallbladder width The diameter is 3.5-4 cm, the longitudinal diameter is 8-9 cm, and the thickness of the gallbladder wall is generally less than 3 cm. Clinical significance Indications cystic stones, extrahepatic bile duct stones, intrahepatic bile duct stones, acute and chronic cholecystitis, gallbladder polyps, gallbladder cancer, jaundice. 1. There is a strong echogenic light group in the gallbladder gallbladder. The trailing edge has sound and shadow. When the body is turned, the stone moves with the body position to the lower direction of the gallbladder, that is, the strong light group moves with the body position to the gravity direction. . 2, gallbladder polyps are mostly single, there is a strong echo or medium echo light group in the gallbladder, there is no sound shadow behind, the echo light group does not move with the change of body position. 3, acute cholecystitis gallbladder larger, gallbladder wall thickening, gallbladder wall can be double-layered due to thickening, poor permeability in the gallbladder, echo unevenness. 4, chronic cholecystitis gallbladder wall thickening, echo enhancement, volume can be small and shrink, often accompanied by stones. 5, gallbladder cancer can be seen in the local gallbladder wall hyperplasia, abnormal echo in the gallbladder and the gallbladder wall is closely related. 6, bile duct or extrahepatic bile duct obstruction intrahepatic bile duct dilatation with gallbladder enlargement. Precautions Preparation before inspection and inspection before body position inspection: 1. Fasting examination: The patient must ban food for more than 8 hours to ensure that the gallbladder and bile duct are filled with bile. 2, try to eat a light diet and a less gas-producing diet 1-3 days before the test to reduce the impact of gastrointestinal contents and gases on the ultrasound resolution. 3, pay attention to body position: supine position is the most commonly used position; can also use right front oblique position: body and bed surface into a 39-45 degree angle. Inspection process 1. Longitudinal cutting of the right costal margin: The probe is longitudinally scanned at the lateral edge of the right rectus abdominis under the right rib. The longitudinal section of the gallbladder can be fully displayed during deep inhalation. 2, right lower cost margin oblique cutting method: the probe is placed horizontally along the rib arch under the right temporal margin, and tilted upwards, showing the right hepatic lobe, right portal vein, right hepatic duct and gallbladder. The probe moves to the left to the xiphoid process, and can display the left portal vein, the left hepatic duct, and the left and right upper branches of the portal vein, the left outer branch, the left inner branch, and the accompanying bile duct. 3, right intercostal oblique cutting method: from the right 6-9 intercostal intercostal oblique scan, showing the right lobe of the liver, gallbladder, right portal vein, right hepatic duct, hepatic duct. 4. Upper and lower longitudinal incision of the right costal margin: the probe is obliquely scanned on the right side of the right side of the line, and then moved to the rib edge for longitudinal scanning, showing the main trunk of the portal vein, the common bile duct, and tracking the common bile duct as much as possible. The next paragraph. 5, under the xiphoid and soil abdomen cross-cut method: the probe is placed horizontally under the xiphoid process, oblique upward, cross-cutting of the left hepatic lobe, showing the left hepatic lobe, left portal vein, left hepatic duct, left portal vein Branch, left outer branch, left inner branch and accompanying bile duct. The probe was scanned across the upper abdomen to show the pancreas and the common bile duct. Not suitable for the crowd Generally no taboos. Adverse reactions and risks This test is generally not harmful to the human body.
