ROENTGENOLOGIC ASPECTS OF VARIOUS TYPES OF HERNIA

Here and there in our routine work, we have encountered cases of hernia in which the roentgen-ray examinations have been very interesting, and at times life saving. Some of these experiences have occurred with ordinary inguinal and postoperative ventral hernia and others with umbilical hernia; but the most striking have been found with diaphragmatic and intra-abdominal herniations. Relatively few of the cases have been studied definitely on account of the hernia; indeed, in many, especially in the small diaphragmatic and retroperitoneal hernias, there has been little in the clinical history or physical examination to suggest the existence of such an abnormality. It is also true that when these cases were worked out, it became evident that there was a definite relation between the hernia and the symptoms, which at first seemed so slightly related. The fact that these types of hernia are very rare should not discourage their study with
