Selective nonoperative management of abdominal visceral lesions is one of the most important and challenging changes that occurred in the traumatized patient care over the last 20 years. The main advantage of this type of management is the avoidance of unnecessary/nontherapeutic laparotomies. The trauma surgeons who deal with this type of treatment are worried of missed abdominal injuries. Modern diagnostic tools (spiral CT, ultrasound, angiography, laparoscopy) allow the trauma surgeon to accurately characterize the lesions to be nonoperative addressed. This literature review discusses the main elements of selective nonoperative management of principle solid visceral lesions (liver, spleen, kidney). We highlight the advantages and limitations of the main diagnostic instruments used for evaluation of trauma patiens allocated to nonoperative management.
