[Volvulus of the gallbladder. Apropos of 2 new cases]. / Volvulus de la vésicule biliaire. A propos de deux nouveaux cas.

Acute torsion or volvulus of the gallbladder is a rare entity, which is seldom diagnosed before operation. Cholecystectomy, which must be performed without delay, is generally easy. Detorsion of the involved organ before cholecystectomy is recommended. The process occurs primarily in the aged. An increased incidence is noted in keeping with more enhanced longevity. Two new cases are reported. The literature is reviewed.
