Wet Navel: umbilical granuloma, omphalomesenteric fistula, urachal fistula.
Umbilical hernias usually close on their own as the infant grows. Infrequently, they complicate, that is, less than 1% of cases. The intestinal content that tends to flow out and enter due to the defect becomes clogged and cannot return to the abdominal cavity, causing pain. Children needs surgery after they reach 4 years old or in the case of large defects greater than 1.5 cm in diameter in children with 3 years old or older. When they present pain, they should not wait for spontaneous closure and should be operated before that age.
It is a lack of healing of the navel after 3 weeks of life. It may be due to an umbilical granuloma, congenital hypothyroidism, or impaired immunity. Generally responds to frequent cures. Other causes of a wet navel that must be ruled out with ultrasound are urachal fistula and Omphalomesenteric fistula that have an indication for surgery.
