The value of an erect abdominal radiograph in the diagnosis of intestinal obstruction.
Simpson A, Sandeman D, Nixon SJ, Goulbourne IA, Grieve DC, Macintyre IM.
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.
