[Acute cholecystitis with and without gallstones. The frequency of surgical interventions in Frederiksberg during the period 1978-1988].

In Frederiksberg Hospital in Denmark the therapeutic procedure for acute cholecystitis requiring operation was altered in 1983. Since then, acute cholecystitis has constituted 15% of all cholecystectomies which corresponds to 15 per 100,000 of the population per annum. 12% of these cases were without stones in the gallbladder. Cases of a calculous cholecystitis do not differ from calculous cases as regards age, sex, clinical history in the month preceding operation and the histological findings.
