Minimizing central bile duct injury during radiofrequency ablation: use of intraductal chilled saline perfusion--initial observations from a study in pigs.

abstract：:Computed tomography (CT) was compared with chest radiography in the assessment of disease severity in 27 patients with sarcoidosis. The CT scans and radiographs were each read twice by two independent observers. Disease extent was assessed on CT scans by visual scoring (0%-100% involvement of the lung parenchyma) and ...

abstract：:Monooctanoin, a cholesterol solvent, was infused into the biliary system of 11 patients. Twenty-eight (74%) of 38 total stones responded to monooctanoin: 16 (42%) decreased in size, and 12 (32%) dissolved completely. Ten stones (26%) did not change in size. We attribute this to inadequate drug-stone contact, which was...
