BACKGROUND: In developed countries, the availability of advanced imaging techniques has reduced the necessity for laparotomy following blunt abdominal trauma in children. Laparotomy rates still remain high in developing countries where these advanced imaging techniques are lacking. A simple management protocol to identify patients who require laparotomy could reduce the laparotomy rate in children with blunt abdominal trauma in these countries. PATIENTS/METHODS: This is a review of children aged 15 years or below managed in our institution over a 5 1/2-year period for blunt abdominal trauma. The children were divided into two groups. Group A consisted of children managed from January 1999 - December 2000. During this period, there was no protocol. Group B consisted of children managed from January 2001 - June 2004. During this period, a simple management protocol was introduced. The laparotomy rates in the two groups were analysed using a simple chi-square. RESULTS: A total of 48 children, representing 63 % of children with abdominal trauma during the study period, were examined (Group A 17; Group B 31). Their ages ranged from 1.5 years - 15 years (median 9 years). Thirty-four were boys, 14 were girls (M:F = 2.4:1). Road traffic accidents accounted for 38 (79.1 %) and falls from heights for 9 cases (18.75 %), and one boy with a hydronephrotic kidney fell off the staircase at home. The diagnosis was clinical, supported by abdominal ultrasound scan (USS) and plain abdominal film. Twenty-eight (58.3 %) children had laparotomy (15 in Group A; 13 in Group B). There was a statistically significant difference in the laparotomy rates between Group A and B (p < 0.01). Nineteen children were managed nonoperatively (2 in Group A; 17 in Group B); one child died before an operation could be performed. There were 59 abdominal organ injuries in 45 children. In 2 children, ultrasound could not diagnose any organ injury. There were 33 splenic injuries; 15 children had splenic conservation, 7 underwent a splenectomy, while 10 were managed nonoperatively. One child with splenic injury died before operation. Of 7 liver injuries, 4 required suturing of lacerations, 1 subcapsular haematoma was left undisturbed at laparotomy, while 2 were managed nonoperatively. There were 4 pancreatic injuries. Three were managed nonoperatively, while 1 associated with duodenal injury had a laparotomy. All 6 gastrointestinal injuries had laparotomy. There were 5 renal injuries: 3 had laparotomy with suturing, while 2 were managed nonoperatively. There were 4 bladder injuries: 2 had laparotomy with suprapubic catheter insertion, while 2 were managed nonoperatively. There were 7 retroperitoneal haematomas in association with other organ injuries. Associated injuries included head injury in 2, long bone fracture in 2, spinal injury and chest trauma in 1 each. There were 4 deaths, 1 before surgery could be performed. CONCLUSION: Blunt abdominal trauma in children resulted mainly from road traffic accidents. The use of a simple protocol supported by ultrasound scan could reduce the laparotomy rate in countries with limited facilities.
