Long-term effects of cholecystostomy on gallbladder function.

In eight patients without a history of gallbladder disease, cholecystostomy was performed for acute pancreatitis (four patients) and blunt abdominal trauma (four patients). In one case only, acute cholecystitis developed after discontinuation of the cholecystostomy. Six patients were followed for a mean period of 3.9 years, after which the gallbladder function was evaluated. Cholecystography and ultrasonography demonstrated good visualisation of the gallbladder without signs of gallstones. The contraction of the gallbladder produced by cholecystokinin varied. This could be due to adhesions impairing the motility of the gallbladder. After cholecystostomy in a previously normal gallbladder, its function will become normal in most patients. If no signs of gallbladder disease develop within the first year after cholecystostomy, the risk of late complications is minimal.
