This is because gall stones are formed over a longer period of time, and this result in a shrunken, fibrotic gall bladder which does not distend easilyo In contrast, the gall bladder is more often enlarged in pathologies that cause obstruction of the biliary tree over a shorter period of time such as malignancy of bile duct, pancreas, leading to passive distention from backpressure.
