Background And AimsPreoperative diagnosis of blunt diaphragamatic rupture is difficult and missed injuries can lead to severe late complications. The aim of this study was to assess the value and reliability of initial chest radiographs in diagnosing blunt diaphragmatic rupture.Material And MethodsA retrospective analysis of initial radiographs of 18 patients with blunt diaphragmatic rupture treated at two Greek Trauma Centers was performed. The chest radiograph was the primary diagnostic radiological tool in all of cases, and the findings were confirmed at operation in all cases.ResultsThe preoperative diagnosis of blunt diaphragmatic rupture on the basis of chest radiographs was made in 16 out 18 patients (89%). The presence of air-containing viscera and an elevated nasogastric tube above the level of the left hemidiaphragm were the most specific signs. Although elevation of the hemidiaphragm was seen in all 18 cases, it is non-specific. A marked elevation of the right hemidiaphragm (more than 6 cm above the level of the left diaphragm), however, was a strong sign of right diaphragmatic rupture.ConclusionsIn spite of the availability of newer diagnostic imaging techniques, the initial chest radiograph is very reliable in detecting most cases with blunt diaphragmatic rupture, and together with high index of suspicion and sound clinical assessment remain the cornerstone in diagnosing these challenging injuries.
