This illustration shows an umbilical hernia. The hernial orifice lies in the naval region.
The leading symtom is pain in the upper abdomen caused by increased pressure in the abdomen (for example by coughing).
With careful and thorough palpation one may feel the hernial orifice and the hernial sack.
Inside the hernial sack there is normally part of the intestine which can potentially lead to ileus.
