Gangrenous Cholecystitis From Gallbladder Volvulus With a Hiatal Hernia.

Gallbladder volvulus is a rare condition involving the rotation of the gallbladder about the cystic duct and vascular pedicle, compromising biliary drainage and blood flow. This report describes a case of gallbladder volvulus presenting in an 88-year-old female with acute onset of right upper quadrant abdominal pain, nausea, and vomiting. Complete work-up included a physical exam, laboratory studies, and computed tomography (CT), which was notable for a markedly distended gallbladder with circumferential wall thickening, pericholecystic fluid, a 12 mm common bile duct, and a hiatal hernia. Given that her initial presentation was consistent with acute cholecystitis, we elected to perform laparoscopic cholecystectomy. The definitive diagnosis of gallbladder volvulus was made intraoperatively after decompression of the gallbladder and visualization of counterclockwise rotation of the gallbladder around the hilum and the infundibulum. This case illustrates the challenge in preoperative diagnosis of gallbladder volvulus, which requires high clinical suspicion to provide prompt surgical intervention.
