摘　　要：目的　探讨站立侧位胸 /腹片在少量气腹检测的应用价值并与站立后前位胸 /腹片相比较。方法　前瞻性评价了站立侧位和后前位胸 /腹片在连续 10 0例已知各种原因气腹中显示膈下游离气体的能力。用McNemar’stest方法评价了两者间敏感性的差异。结果　站立侧位胸 /腹片对患者气腹的显示率为 98% ;站立后前位胸 /腹片的显示率仅为 80 % ;站立侧位胸 /腹片显示气腹明显优于站立后前位胸 /腹片 (P <0 .0 5 )。结论　在检测少量气腹时 ,站立侧位胸 /腹片较站立后前位胸 /腹片更敏感。Objective To determine whether upright lateral chest/abdominal radiographs were more sensitive than upright posteroanterior chest/abdominal radiographs in determining pneumoperitonium. Methods One hundred consective patients with known pneumoperitonium from a variety of causes were prospectively evaluated for the ability of upright posteroanterior and lateral chest/abdominal radiographs to show subdiaphrgmatic air. The difference in sensitivity was evaluated by means of McNemar's test. Results The upright lateral chest/abdominal radiographs showed pneumoperitonium in 98% of the causes, while the posteroanterior chest/abdominal radiographs showed pneumoperitonium in only 80%. The upright lateral chest/abdominal radiographs were significantly better than the posteroanterior chest/abdominal radiographs ( P <0.05) at showing pneumoperitonium. Conclusion The upright lateral chest radiograph is more sensitive than the upright posteroanterior chest/abdominal radiograph in detecting small amounts of pneumoperitonium.[
