Volvulus of the gallbladder: a case report.

Torsion of the gallbladder is a surgical emergency that occurs predominantly in the elderly and whose presentation is indistinguishable from acute cholecystitis. If patients being treated conservatively for acute cholecystitis fail to improve promptly, laparotomy is indicated, because the diagnosis of gallbladder torsion cannot be excluded. Cholecystectomy before the onset of gangrene and rupture of the gallbladder is curative.
