Gallbladder volvulus is a relatively rare condition in which there is a rotation of gallbladder around the axis of cystic duct and artery.
Symptoms are nonspecific, however right upper quadrant pain and vomiting are similar to biliary colic. Laboratory evaluations are often nonspecific. If there is fever or leucocytosis, then acute cholecystitis may have developed.
It has been observed on patients with significant weight loss, in which there is loss of pericholecystic fat.
Complications are related to torsion with vascular compromise and resultant gallbladder ischemia. In this condition both gangrenous change and perforation may occur.
- large floating gallbladder
- wall thickening
- gallbladder outside the normal anatomical fossa
- massively distended gallbladder
- pericholecystic fluid
- gallbladder outside the normal fossa
- loss of enhancement
- abrupt tapering of cystic duct
Cholecystectomy is the preferred treatment.
