Bwala Background Trauma is gradually becoming a major cause arrow injuries. Fourteen (42.4%) patients had abdominal of disability and it can be of any form, physical or organ evisceration; of them, nine were as a result of emotional. For the surgeon the physical form is of major gunshot injuries. Routine exploratory laparotomy was interest, especially its causes and incidence, which can be carried out in all 33 patients. Seven (21.2%) were operated influenced by environmental or social factors. on with simultaneous resuscitation in the immediate laparotomy group, and 26 (78.8%) underwent delayed Aim The aim of this work was to study the incidence, laparotomy. There was a negative laparotomy in four etiology, principles of management and outcome of (12.1%) patients, two of whom had only omental children with penetrating abdominal injuries. evisceration with no other accompanying visceral injuries, Materials and methods This was a 2-year prospective and two without evisceration.

Data followed by IED in 11 (33.3%) children. Other causes of collected from patients included either rural or urban penetrating abdominal injuries are shown in Table 2. dwellers, cause of the penetrating abdominal injury There were 14 (42.4%) children with evisceration of (gunshot, bomb blast/IED, arrow shot, stab wounds, abdominal organs and 19 (57.6%) without evisceration. impalement injuries), and the presence or absence of visceral evisceration. For those with evisceration the type The eviscerated organs were the omentum with jejunum of the eviscerated organ and the assault device were in four, jejunum alone in two, ileum in two, stomach with ascertained. The time that the patient’s presented to the omentum in two, the omentum only in three and the the Accident and Emergency Department was noted as stomach alone in one child. Gunshot injuries were a follows: less than 6 h; 6–12 h, and more than 12 h after common cause of evisceration (64.3%), followed by IED injury. Those patients who presented less than 6 h are (28.6%) (Table 2). As regards duration of presentation to classified as the immediate presentation group, whereas the Accident and Emergency Department, most of the those who presented between 6 and 12 h and those who patients (19, 57.6%) presented less than 6 h of injury, presented more than 12 h of injury are the delayed and eight (24.2%) and six (18.2%) children presented late presentation groups, respectively.
