摘　　要：目的:探讨常规腹部立位平片漏诊膈下游离气体的原因及技术改进。方法:15例疑有气腹但腹部立位平片阴性者加拍胸部正位片,观察有无膈下游离气体。结果:15例中12例胸片可显示膈下少量游离气体。结论:X线投照中心线位置不同会影响膈下游离气体的显示,胸片较腹部立位平片更容易显示少量气腹。Objective： To analyse the reason of negative result of the standing abdominal plain film in pneumoperitoneum,com-pared with the chest X-ray film.Methods： A total of 15 patients,who were suspected with pneumoperitoneum,underwent chest X-ray if their standing abdominal plain films were negative.Results： 12 of the 15patients got positive findings in their chest X-ray film,free gases under the diaphragm were found.Conclusion： The position of centrage could influnce the display of pneumoperitoneum when the gases under the diaphragm was too little.Chest X-ray has more advantage than standing abdominal plain film.
