Abstract
Torsion of the gallbladder is a rare disease presenting the clinical picture of acute abdomen, because the gallbladder twists by some causes, becomes ischemic and is necrotized due to cessation of its blood supply. Its diagnosis has been difficult. Recent progress of imaging techniques such as ultrasonography and CT scanning enabled us to diagnose it preoperatively. Two cases of torsion of the gallbladder are reported. One of them was preoperatively diagnosed by a contrast-enhanced CT scan. In both cases an emergency operation was performed and each postoperative course was uneventful.
It should be kept in mind that torsion of the gallbladder is one of the diseases leading to the acute abdomen.
