[Peritoneography for identification of non palpable herniation]

Peritoneography with trijodic contrast medium is a simple but very effective method to identify non palpable herniations causing inguinal pain of unknown origin. It is also very useful for early detection of recurrent herniations after surgery as well as for diagnosis of non palpable umbilical herniations in adipose patients, and for demonstration of herniastions of the abdominal wall after trauma. Technique of investigation and radiological symptoms are described following experience with 154 outpatients. In 25% of these patients during clinical investigation no herniation was found.
