[In-vitro activity pattern of gallbladder muscle tissues in patients with and without gallstones--variable response to cholecystokinin, motilin and neurotensin].
Data about gallbladder motility in stone disease and stone free conditions are discussed controversially. This study is aimed at to evaluate in vitro the responses of human gallbladder muscle stripes to cholecystokinin, motilin and neurotensin. Following the results, a stratification of the "stone-disease-group" seems to be necessary: 41% of the gallbladders (stone disease) demonstrate a deep reduction in contractility to cholecystokinin ("non-contractors"), whereas 59% of the gallbladders contract in the same pattern like the controls ("contractors"). Interestingly, the majority of the gallbladders in the "contractor" group demonstrate a high spontaneous activity which is absent in stone free gallbladders. Motilin and neurotensin either do not induce any effect.
