Die sonographische Gallenblasenwandverdickung und ihre diagnostische Bedeutung bei intensivpflichtigen Patienten

subject

description

In a prospective study including 398 intensive-care patients, we analysed the ultrasonographic relevance of a gallbladder wall thickening. In 24 of 398 (6%) cases a wall thickening was found that could be differentiated into two types of walls. In 20.8% (5/24) the gallbladder wall thickening was an expression of an acute cholecystitis. In further differential diagnosis of a gallbladder wall thickening pathological states with hypoalbuminaemia occupy the prime position. The pathological mechanism has not yet been completely clarified. Hypoalbuminaemia without inflammatory alterations of the organ was found in 37.5% of the cases with gallbladder wall thickening. In 41.6% of the patients the wall thickening had to be taken as a non-specific ultrasonographic sign. On the whole, therefore, gallbladder wall thickening has thus to be valued primarily as non-specific sign. In a few cases only, it implies an autonomous affection of the gallbladder.
