This study was done to determine whether upright lateral chest radiographs were more sensitive than upright posteroanterior chest radiographs in detecting pneumoperitoneum.
We prospectively evaluated the ability of upright posteroanterior and lateral chest radiographs to show subdiaphragmatic air in 100 consecutive patients with known pneumoperitoneum from a variety of causes. The difference in sensitivity between the two was evaluated by means of McNemar's test.
The upright lateral chest radiograph showed pneumoperitoneum in 98% of the cases; the upright posteroanterior chest radiograph showed pneumoperitoneum in only 80%. The upright lateral chest radiograph was significantly better at showing pneumoperitoneum than was the upright posteroanterior chest radiograph (p < .01).
The upright lateral chest radiograph is more sensitive than the upright posteroanterior chest radiograph in detecting small amounts of pneumoperitoneum. When there is a strong clinical suspicion of a perforated hollow viscus, it may be of benefit to include an erect lateral chest radiograph as part of the acute abdominal series.
本研究旨在确定立位侧位胸片在检测气腹方面是否比立位后前位胸片更敏感。
我们前瞻性地评估了立位后前位和侧位胸片对100例因各种原因导致气腹的连续患者膈下气体的显示能力。通过McNemar检验评估两者敏感性的差异。
立位侧位胸片显示气腹的病例占98%；立位后前位胸片仅显示80%。立位侧位胸片在显示气腹方面明显优于立位后前位胸片（p < 0.01）。
立位侧位胸片在检测少量气腹方面比立位后前位胸片更敏感。当临床上高度怀疑有空腔脏器穿孔时，将立位侧位胸片作为急性腹部系列检查的一部分可能有益。
