Abstract
Torsion of the gallbladder in children is a very rare condition. Only 23 children have been reported in the Japanese literature. Because of its rarity, the correct diagnosis is very difficult to make preoperatively. Only four cases were accurately diagnosed in the series of 23 cases. We experienced such a case in a 3-year-old girl who was diagnosed as having acute perforative appendicitis before surgery. On laparotomy, the enlarged and necrotic gallbladder was revealed. It was a floating gallbladder, which twisted clockwise by 180° around the cystic duct. Cholcystectomy was performed and the patient was discharged from the hospital in a well improved condition on the 9th hospital day.
