Secondary cholangiography: Done after a biliary drainage intervention. In both cases fluorescent fluids are used to create contrasts that make the diagnosis possible. Cholangiography has largely replaced the previously used method of intravenous cholangiography (IVC). [citation needed]
Percutaneous transhepatic cholangiography, percutaneous hepatic cholangiogram (PTHC) is a radiological technique used to visualize the anatomy of the biliary tract. [1] A contrast medium is injected into a bile duct in the liver , after which X-rays are taken.
Next, thrust in an inward and upward motion on the diaphragm. This will force air out of the lungs and remove the blockage. Repeat these abdominal thrusts up to five times, the doctor advised.
Other complications (less than 1%) may include heart and lung problems, infection in the bile duct called cholangitis, that can be life-threatening, and is regarded as a medical emergency. Using antibiotics before the procedure shows some benefits to prevent cholangitis and septicaemia. [25] In rare cases, ERCP can cause fatal complications. [26]
Cholangiography: Imaging the bile ducts within the liver to look for areas of blockage. Biopsy: Taking of a tissue sample from the area of interest for pathological examination from a percutaneous or transvenous approach. [4] Fine-needle aspiration: obtaining cells from a tissue or organ under ultrasound guidance.
Oral cholecystography is a radiological procedure used to visualize the gallbladder and biliary channels, developed in 1924 by American surgeons Evarts Ambrose Graham and Warren Henry Cole. It is usually indicated in cases of suspected gallbladder disease, and can also be used to determine or rule out the presence of intermittent obstruction of ...
Percussion and resonance (the quality and feeling of sound) are used to examine lung movement and possible lung conditions. Specifically, percussion is performed by first placing the middle finger of one hand over the area of interest. The middle finger of the other hand is used to strike the last joint of the placed finger.
A lung biopsy is an interventional procedure performed to diagnose lung pathology by obtaining a small piece of lung which is examined under a microscope. [ 1 ] [ 2 ] Beyond microscopic examination for cellular morphology and architecture, special stains and cultures can be performed on the tissue obtained.
