The management of blunt abdominal traumatism with a moderate amount of free peritoneal fluid and without solid organ injury as well as the one of minimal penetrating trauma is controversial. We present three cases of blunt abdominal trauma and two of penetrating trauma that underwent diagnostic laparoscopy in our department. We found a small bowel perforation in one of the cases of blunt trauma that was repaired by externalization of the jejuna loop by one of the ports. In the other two cases we found intestinal and mesenteric contusions and free fluid that were treated by peritoneal drainage. One of the cases of penetrating trauma presented omentum evisceration with no other injuries and the second presented a gastric perforation that needed reconversion to laparotomy. In our experience and according to literature, laparoscopy should be taken into account as a diagnostic procedure and sometimes also therapeutic in selected cases of both blunt and penetrating abdominal trauma in pediatric population.
