The significance of conjugated phenobutiodil (biliodyl) in the intestine in the absence of gallbladder opacification a preliminary assessment

Abstract

Conjugated phenobutiodil (Biliodyl) in the small and large bowel can be recognised by its fine, homogeneous appearance. The findings in 41 patients undergoing oral cholecystography with subsequent clinical follow-up are reported. When the gallbladder fails to opacify on oral cholecystography, the presence of conjugated contrast medium in the intestine appears to provide reasonable evidence that the gallbladder is diseased
