There are several of these and you must not confuse them. You will see: (1) The common true umbilical herniae of children which rarely need surgery. (2) The much rarer paraumbilical herniae of adults through or beside the umbilicus which usually needs surgery. (3) Small and usually harmless epigastric herniae of the linea alba between the xiphoid and the umbilicus, which usually do not need surgery, but are are easy to repair if they do. (4) Herniae which follow incisions, particularly Caesarean sections.
