Retroperitoneal organ injury caused by anterior penetrating abdominal injury in children

Objective: To describe the retroperitoneal organ injury pattern after anterior penetrating abdominal injury in children. Setting: The paediatric surgical department of a university teaching hospital. Patients and methods: All children presenting with firearm and stab wounds to the anterior abdomen between January 1983 and April 2001. Results: Forty-nine children (34%) with penetrating anterior abdominal wounds had retroperitoneal organ injury. The most injured organs were the descending colon in 17 patients (35%), ascending colon in eight patients (16%), and kidney in seven (14%). The most commonly associated injured organ was the small bowel. Postoperative septic complications were seen in 10 patients (20%). The most common postoperative complication was wound infection. When we compared patients with intraperitoneal organ injury with patients with retroperitoneal injury, there was no difference in parameters such as age, associated organ injury, morbidity and mortality between both groups. The main causative factor of retroperitoneal injuries was shotgun wounds, whereas it was stabbing in intra-abdominal injuries (P < 0.05). The number of injured organs and the hospital stay is significantly greater in retroperitoneal organ injuries, and the trauma scores such as the Injury Severity Score (P < 0.001) and the Penetrating Abdominal Trauma Index (P < 0.001) were found to be significantly higher. Conclusion: Retroperitoneal organ injury is commonly associated with anterior penetrating abdominal trauma. Even if there is no preoperative sign of retroperitoneal organ injury, an exploratory laparotomy and a meticulous retroperitoneal exploration should also be performed for associated retroperitoneal organ injury.
