| 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100例已知各种原因气腹中显示膈下游离气体的能力。用McNemar's test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<0.05)。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. |
