Gallbladder torsion: a rare cause of acute abdomen in a 12-month old child.

Abstract

Background: Gallbladder torsion is a rare cause of an acute abdomen, predominantly occurring in elderly women and less frequently diagnosed in the pediatric population. The diagnosis is difficult and rarely made preoperatively. However, suspicion needs to be raised in children with acute onset of abdominal pain. Ultrasound can demonstrate different signs putting forward the diagnosis but findings are often non-specific, therefore clinical suspicion should prompt a laparoscopic exploration.Case presentation: We report a case of a 12-month old girl consulting with progressive abdominal discomfort and vomiting. Ultrasound revealed an enlarged gallbladder with thickening of the wall but without demonstrable color Doppler flow and a more horizontal orientation outside its normal anatomic fossa. Gallbladder torsion was suspected. Emergency laparoscopic exploration confirmed the diagnosis and a laparoscopic cholecystectomy was performed. The postoperative course was uneventful.Conclusions: Gallbladder torsion, although rare, should be included in the differential diagnosis of an acute abdomen in children. Early recognition is necessary for a favorable outcome. The diagnosis might be supported by ultrasound but remains difficult, which is why laparoscopic exploration should be considered when the diagnosis remains unclear.
