The removal of retained biliary tract stones: report of 105 cases.

The removal of retained biliary stones by the use of the steerable catheter and wire basket after removal of the T-tube has proven itself to be valuable and safe technique. A success rate of 90% or better can be achieved by a radiologist quite quickly. The reduction in morbidity and absence of mortality makes non-operative removal of stones a very desirable service in any hospital doing a significant amount of biliary surgery.

Gray-scale ultrasound of billary tract disease. A correlative study with percutaneous transhepatic cholangiography.

Gray-scale ultrasound can be useful in the diagnosis of extrahepatic obstructive jaundice by the demonstration of dilatation of the biliary tree. The present study was undertaken to test the specificity and sensitivity of gray-scale ultrasound (US) in the detection of dilation of intrahepatic bile ducts, as compared to percutaneous transhepatic cholangiography (PTC). Forty-seven patients were studied prospectively by both techniques. In 23 patients demonstrated by PTC to have dilated intrahepatic ducts, 18 were detected by US. Of the 11 patients shown to have non-dilated ducts by PTC, all were accurately predicted by US. In 13 cases in which PTC was unsuccessful, the US study showed 12 to be non-dilated and one to be mildly dilated. Ultrasound as a non-invasive technique, should be the primary imaging technique in the evaluation of possible extrahepatic obstructive jaundice.
