title: [Imaging of intestinal obstructions].
abstract: The diagnosis of intestinal obstruction still rests on radiography of the abdomen without preparation. Three X-ray films must systematically be taken: a general film and a film centred on the diaphragmatic domes with the subject standing; another general film with the subject lying on his back. It is relatively easy to identify the obstructed segment, but the cause of obstruction remains difficult to determine. For small bowel obstruction, emergency surgery is often necessary. If the patient's condition permits, it may be useful to opacify the dilated segment in order to study the nature of the obstacle. Colonic obstruction is opacified through the anus, this route being more informative. There are two types of acute obstruction: by occlusion and by strangulation. The various causes are considered, but there are also incomplete obstructions and dilatations without obstruction.
