title: Role of cholesterol and calcium bilirubinate crystals in acute postoperative acalculous cholecystitis.
abstract: Acute acalculous cholecystitis is rather unusual, but it is considered an increasing entity. Particularly interesting are the post-traumatic or post-operative forms of acute acalculous cholecystitis. Ischemia of the gallbladder and biliary stasis are the most likely pathogenetic factors. A case of acute acalculous cholecystitis after total gastrectomy for cancer is presented. Particular emphasis is put on the significance of cholesterol and calcium bilirubinate crystals findings in the bile of the gallbladder. The pathogenetic role of this microscopic form of lithiasis in post-operative acalculous cholecystitis is discussed. It is concluded that all surgeons should be aware of this pathology since it is becoming much more common to be faced with elderly patients having life-threatening post-operative gallbladder complications unrelated to macroscopic lithiasis.
