Blunt abdominal injury in children can be a significant diagnostic and therapeutic challenge. The extent and localization of organ damage cannot be always thoroughly investigated noninvasively and in spite of modern imaging techniques and a laparotomy may be necessary for diagnosis, even though it carries a significant morbidity. We present a rare case of isolated gastric rupture after blunt abdominal injury in a 12 year old boy that sustained a bicycle accident. He was hemodynamically stable, had signs of acute abdomen and axial tomography was inconclusive as of the site of visceral perforation. Definitive diagnosis and treatment were carried out laparoscopically with excellent results. Laparoscopic surgery in cases of blunt abdominal injury with gastric rupture can serve both as a diagnostic and therapeutic modality with the additional advantage of being less traumatic. The accumulation of relevant experience is mandatory in order to establish this modality in the diagnostic and therapeutic protocols.
