Infantile umbilical hernia can be defined clinically as a herniation of intra-abdominal viscera, usually intestine, through the umbilical ring within a peritoneal sac. It is covered by skin and is present from birth. Some authors specify that a true umbilical hernia is a saccular swelling, present and protruding on straining. Others use less strict criteria, with palpability of a gap at the umbilical orifice alone being sufficient
