The value of an erect abdominal radiograph in the diagnosis of acute intestinal obstruction has been studied. Four observers independently assessed 100 supine abdominal films and then reassessed them in combination with an erect film. The addition of the erect film did not significantly increase the accuracy of diagnosis of obstruction or help in the correct identification of its level. The presence or absence of gas in the rectum was of no diagnostic value.
立位腹部X线平片在急性肠梗阻诊断中的价值已得到研究。四位观察者独立评估了100张仰卧位腹部平片,然后结合立位片重新评估。立位片的添加并未显著提高肠梗阻诊断的准确性,也无助于正确判断梗阻部位。直肠内有无气体无诊断价值。
