A CASE OF INCOMPLETE TORSION OF THE GALLBLADDER DIAGNSED BEFORE OPERATION

We present a case of incomplete torsion of the gallbladder in a 72-year-old woman which was preoperativery diagnosed with US, CT, and ERCP. The patient admitted to the hospital complaining of right upper abdominal pain, fever and vomiting. Cholecystitis was suspected and conservative treatments led to alleviation on the 5th hospital day. However, US and CT revealed the enlarged gallbuladder and locating at the mid-area of upper adbdmen. The wall was thikend at the neck of gall bladder and it looked like a tumor, especially in contrast-enhanced CT. The gallbladder could not be seen on ERCP, and peak-shaped cystic duct was observed in the common bile duct side. It suggested that the malrotaion and obstruction of cystic duct caused torsion of the gallbladder. Cholecystectomy was performed and we confirmed the values of US, CT, and ERCP for torsion of the gallbladder.
