Reimaging study in the management of blunt abdominal trauma in children: a low income country single center experience

Introduction: The abdomen is the most prevalent site of primarily unidentified fatal injury after blunt trauma, and represents the third major affected part. However, follow-up strategies of intra-abdominal injuries remain controversial. The aim of this study is to describe the characteristics of children with blunt abdominal trauma (BAT) and who presented radiographic amendments in re-imaging studies and predict factors that could identify patients group requiring control in this population. Methods A retrospective study was conducted in the department of pediatric surgery and the intensive care unit of Monastir involving all patients under the age of 14 years old who were admitted for blunt abdominal trauma between January 2010 and December 2021.An analysis of epidemiological, clinical, radiological and therapeutic management characteristics were performed. Results A total of 151 patients were included in this study with a mean age of six years. The sex ratio (m/f) was 2.7. Most trauma circumstances were related to road accidents (43.7%) and falls (32.4%). The liver, the spleen, and the kidneys were the most frequently affected organs. A combination of intra-abdominal lesions was recorded in 32 cases. 84% of the cases (110/131) of the reimaged patients had no complications, compared to 16% (21/131) who developed intra-abdominal complications. The complicated reimaging findings were significantly associated with high grade hepatic and renal injuries (p=0.019 and 0.002, respectively), and patient symptom persistence or development (p=0.001). Conclusion It is safe to avoid performing reimaging studies if clinical progression remains uneventful in children with low-grade hepatic, splenic, and renal lesions. However, the clinical assessment is the most crucial consideration during BAT management in children.
