*1.2.3 Defects of the gall bladder and bile ducts*

In about 30% of patients with cystic fibrosis, atrophic gall bladder, or the lack thereof, also its defects and/or of bile ducts is reported. No correlation between cirrhosis and abnormalities in the gall bladder and/or bile ducts has been observed. Gallbladder hydrops and lithiasis are more commonly observed in patients with

cystic fibrosis than the healthy population. The narrowing of the distal regions of the bile ducts is frequent and may occur in even 90% of CF patients and contribute to the formation of gallstones [33, 34].
