Repetitive ultrasound examinations aided a correct clinical decision making and an adequate management.Apossibility of the gall bladder perforation following blunt injuries of the abdomen must be considered mainly in younger patients with nonspecific abdominal pains. The risk increases after abuse of alcohol or after prolonged starvation.
