A 65-year-old woman presented with right hypochondralgia of three days duration. There were no signs of peritonitis. Ultrasound and CT scans showed gallbladder enlargement and thickening of the gallbladder wall, suggesting acute cholecystits. Soon after emergent percutaneous transhepatic gallbladder drainage (PTGBD), the patient's laboratory tests and symptoms improved. Laparoscopy was performed electively on the 8th day after admission. Once the adhesion had been dissected, the gallbladder was found to be twisted clock/wise 180 degrees around the cystic duct. After the torsion had been corrected the gallbladder was resected laparoscopically. The gallbladder was found to be minimally attached to the liver and was thought to be a Gross type II “floating gallladder”. Torsion of the gallbladder is rare in patients with an acute abdomen. Emergent cholecystectomy for torsion of the gallbladder is recommended since the gallbladder can easily necrotize or become perforated due to ischemic change. In our case, emergent surgery was avoided by the use of PTGBD. Elective laparoscopic cholecystectomy was then successfully performed.
