Umbilical swelling

The umbilical fossa is moist, swollen, and has a smelly exudation. It can be purulent or mixed with bloody symptoms. Omphalitis is a bacterial infection of the umbilical stump. According to the age of onset, there can be adult umbilitis and neonatal umbilitis. According to the pathological process, there are two types of acute umbilitis (acute omphalitis) and chronic umbilitis (chronic omphalitis). Acute umbilical inflammation is acute cellulitis of the periumbilical tissue. If the infection progresses, it may be accompanied by abdominal wall cellulitis or may develop into umbilical abscess, and there is a risk of peritonitis and sepsis. The pathogenic bacteria are Staphylococcus aureus. Chronic umbilitis is a chronic inflammation of the umbilical cord caused by the irregular treatment of acute umbilitis, long-lasting or unhealed wounds and foreign body after the umbilical cord falls off.
