The study reports five cases of postoperative acute acalculous cholecy
stitis. Clinical symptoms are upper abdominal pain, fever, jaundice or
an unexplained septic shock. Biology orients the diagnosis but only g
allbladder ultrasonography and, to a lesser degree, hepatobiliary scin
tigraphy are really diagnostic. As mortality is high and increases wit
h waiting, emergency cholecystectomy is the treatment of choice.
