Abstract
Torsion of the gallbladder which occurs mostly in adults is extremely uncommon in children. Only 15 pediatric cases have been published in Japanese literature so far. Because of its rarity, it is difficult to make a correct preoperative diagnosis. Only two cases was accurately diagnosed in the series of 15 cases. In this paper, we described a case of 13-year-old boy who was diagnosed as having acute cholecystitis by ultrasonography before surgery. At laparotomy, it was revealed that the gallbladder was enlarged and necrotic because of torsion at the bladder neck of 540 degree clockwise. Cholecystectomy was performed, and the patient was discharged uneventfully on the 13th day after operation. This case suggests that we should consider torsion of the gallbladder in acute abdominal emergencies.
