[Gallbladder torsion]

Abstract

Background: Gallbladder torsion or gallbladder volvulus is a rare condition of the hepatobiliary system, defined as a rotation of the gallbladder along its long axis causing an interruption of the vascular and biliary flow. It clinically mimics acute cholecystitis which makes accurate preoperative diagnosis challenging.

Case description: We present the case of an 81-year-old woman with a three day history of upper-right quadrant pain, nausea, vomiting and no evidence of cholelithiasis on imaging. Emergency cholecystectomy was performed, intraoperative findings included a necrotic gallbladder with complete torsion. After the secondary diagnosis of gallbladder torsion, the clinical and radiologic findings were reviewed retrospectively.

Conclusion: The acute onset of abdominal pain without clear progression over time should initially be the trigger for differential diagnostic consideration of gallbladder torsion. This combined with the previously described risk factors and radiological characteristics could result in successful pre-operative diagnosis of gallbladder torsion.
