[Chronic recurrent acalculous cholecystitis--apropos 6 clinical cases].

Over the period 1991 through 1994, a total of 120 patients with chronic cholecystitis are operated on. In six of them (5 per cent) no concrements in the gallbladder and biliary ducts are discovered. In 83.3 per cent the echographic study fails to detect concrements in the gallbladder and biliary ducts. All patients are subjected to cholecystectomy, and in all of them markedly expressed adhesions are found. The early and long-term operative results are estimated as very good. The positive therapeutic effect is durable and persists for many years.
