Objective: To evaluate the pattern and outcome of blunt abdominal trauma using haemodynamic stability and ultrasonography in the selection of patients for nonoperative management in a facility without computed tomogram. Methods: Patients admitted with blunt abdominal trauma between February 2005 and January 2010 were prospectively studied. Haemodynamic stability and sonography formed the basis for selecting patients for nonoperative management. Results: In total, 58 patients suffered blunt abdominal trauma and 19(33%) patients were successfully managed nonoperatively suffered blunt solid abdominal organ injuries. Road traffic accidents inflicted 17(89%) patients while 2(11%) patients sustained sports injury (football). The spleen was the commonest solid organ injured 12(60%), while the liver and kidney were injured in 6(30%) and 2(10%) respectively. Associated injuries were fractured left femur recorded in 3(16%) patients and fractured rib in a patient (5%). Conclusion: Nonoperative treatment is a safe and effective method in the management of haemodynamically stable patient with blunt solid abdominal organ injury. This translated to a reduction in hospital stay, absence of the risk of blood transfusion as well as attendant morbidity and mortality associated with laparotomy. Establishment of trauma system, provision of diagnostic and monitoring facilities, good roads, and education on road safety is recommended for improved outcome.展开更多

They are the first cause of small bowel obstruction. Diagnosis is based on clinical evaluation, water-soluble contrast followthrough and computed tomography scan. For patients presenting no signs of strangulation, peritonitis or severe intestinal impairment there is good evidence to support non-operative management. Open surgery is the preferred method for the surgical treatment of adhesive small bowel obstruction, in case of suspected strangulation or after failed conservative management, but laparoscopy is gaining widespread acceptance especially in selected group of patients. "Good" surgical technique and anti-adhesive barriers are the main current concepts of adhesion prevention. We discuss current knowledge in modern diagnosis and evolving strategies for management and prevention that are leading to stratified care for patients.展开更多
