cholangiography

There are at least two kinds of cholangiography:

Does cholangiography establish the nature of a biliary stricture?

On the third postoperative day, the T-tube was removed after cholangiography showed sufficient drainage.

The diagnosis had been made by endoscopic retrograde cholangiography 3 years (range 1-6 years) before the study.

However, cholangiography is the best, and final, approach to show the enlarged bile ducts as a result of Caroli disease.

Intravenous cholangiography is a form of cholangiography that was introduced in 1954.

Endoscopic retrograde cholangiography showed the cystic duct and the ductus choledochus to be free of stones.

Bile sampling at the time of endoscopic or percutaneous cholangiography, with subsequent cytological examination, has been carried out for over 20 years.

Peroperative cholangiography showed two clips partially placed over the CBD, which were subsequently removed.

Possibly, selected or routine use of intraoperative cholangiography could have prevented or diagnosed some of the injuries.

This can additionally be performed as part of a percutaneous transhepatic cholangiography, then a form of interventional radiology.

When this happens, percutaneous transhepatic cholangiography (PTC) may be needed to relieve pressure.

The endoscope retrograde cholangiography confirmed the diagnosis of an occluding stone in the cystic duct (Fig 3).

Before the surgeon removes the gallbladder, you may have a special X-ray procedure called intraoperative cholangiography, which shows the anatomy of the bile ducts.

The diagnosis was made in 57 patients by endoscopic retrograde cholangiopancreatography and in three by percutaneous transhepatic cholangiography.

Cholangiography accurately locates the site of a stricture in the biliary tree and radiological features may suggest the presence of malignant disease.

External imaging (ultrasound or computed tomography) and cholangiography cannot, however, differentiate benign from malignant biliary strictures.

Percutaneous transhepatic cholangiography was carried out under intravenous sedation after intravenous administration of broad spectrum antibiotics and crystalloids.

Six patients, all with malignant strictures, had bile samples taken at both endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography.

The positivity rate for samples collected at endoscopic retrograde cholangiopancreatography was 31% in comparison with 22% at percutaneous transhepatic cholangiography.

PTC (percutaneous transhepatic cholangiography): A procedure used to x-ray the liver and bile ducts.

Diagnosis is made from features on direct cholangiography indistinguishable from those of primary sclerosing cholangitis, but there is no link with inflammatory bowel disease.

Moreover, endoscopic and percutaneous cholangiography have become during the 1980s widely used methods to diagnose bile duct abnormality, including common duct stones.

Intraoperative cholangiography, performed in only one patient in this study, can be helpful in delineating the biliary anatomy to avoid iatrogenic injury.

Diagnosis is best with contrast cholangiography showing diffuse, multifocal strictures and focal dilation of bile ducts, leading to a beaded appearance.
