Although subdiaphragmatic gas on an erect chest or abdominal radiograph usually indicates the presence of a gastrointestinal perforation, this sign is present in only 60-80% of cases. Other less well known radiographic signs of perforation that may nonetheless be of utmost importance in diagnosis are described. The presence of such signs may then prompt further diagnostic procedures or surgical intervention as appropriate.
尽管立位胸部或腹部X线片上的膈下游离气体通常提示存在胃肠道穿孔,但该征象仅在60% - 80%的病例中出现。本文还描述了其他一些不太为人所知但在诊断中可能极为重要的穿孔影像学征象。这些征象的出现可能会促使采取进一步的诊断措施或适时进行手术干预。
