摘要

腹腔積氣最常因腹腔內中空臟器穿孔所致，其中以胃腸潰瘍穿孔居首位。利用站立位之胸腹部X光，可以得到兩側橫膈膜下的游離空氣，是其診斷的重要關鍵，但病人若因某種情況，無法站立時，腹部X光的判讀配合超音波和電腦斷層攝影是不可或缺的，故提出此病例報告供大家參考。

Pneumoperitoneum are most frequently resulted from visceral perforation which is more often found in perforated peptic ulcer. The radiographic findings are characteric and most important in diagnosis. On standing chest film, which is the most pathognomonic tool, free air presents in the subphrenic space is the optimal diagnostic key point. But, in some patients when standing is not available, if the patient is too sick to stand or sustained fracture of bone, an abdominal film will give some informations. However, the findings are subtle and less sensitive. When ultrasound used as a screening tool for abdominal pain, the highly alertness with conjunction findings of plain fm or CT scan, may provide infromation usefully and precisely in detecting extraluminal gases.
