Ultrasound in biliary tract disease.

Biliary tract excretion of cefazolin, cephalothin, and cephaloridine in the presence of biliary tract disease.

The biliary tract excretion of three cephalosporins, cefazolin, cephaloridine, and cephalothin, was compared in patients with biliary tract disease. In the absence of obstruction, mean antibiotic levels in bile from gall bladder and common duct in patients undergoing cholecystectomy were highest for cefazolin (17 and 31 mug/ml, respectively) than either cephaloridine (7 and 9 mug/ml) or cephalo...

Ultrasound diagnosis of liver and biliary tract lesions.

Over a two year period, 323 livers were examined using ultrasound. Majority of these cases were icteric and ultrasound could distinguish obstructive from non-obstructive jaundice. Primary and secondary liver tumours were also detected. Liuer abscesses, and radiolucent gallstones were picked up by ultrasound, the areas under study being scanned using standard methods as outlined by various ultra...

Biliary tract neoplasms: detection and staging CT and Ultrasound

Most biliary tract neoplasms are malignant and have been traditionally divided into cancers of the gallbladder, the extrahepatic bile ducts, and ampulla of Vater. Although infrequent, bile duct carcinomas and cancer of the gallbladder are not rare. In the United States, an estimated 6,000 to 7,000 new cases of carcinoma of the gallbladder and 3,000 to 4,000 new cases of carcinoma of the bile du...

The rise of minimally invasive surgical techniques during the past 20 years has been one of the more dramatic developments in modern medicine. Minimally invasive procedures are now widely accepted for treatment of diseases involving many different organ systems. Minimally invasive procedures may be more common and more accepted in the treatment of diseases of the biliary tract than in any other...
