[Sonographic studies of gallbladder kinetics in childhood--a comparison between healthy and mucoviscidosis patients].

In mucoviscidosis, the gallbladder can show signs of disease even in childhood. In 10 of 35 mucoviscidosis patients the authors found thickening of the walls, gallstones and micro-gallbladders on sonographic examination. Compared with healthy children (N = 70), the mucoviscidosis patients showed impairment of the kinetics of the gallbladder to an increasing extent in step with progressing age. X-ray films of the gallbladder were preferably taken while using a preparation containing bile acids for better absorption of the contrast medium. When using this preparation, the gallbladder was found to yield good contrast more frequently than with double-dose cholecystography recommended in literature. However, oral cholecystography yielded additional information in one case only where sonography had failed to produce a clear sonographic image of the gallbladder.
