Patent Vitelline Duct

A Patent Vitelline Duct is a rare condition where a small tube that normally disappears before birth remains open, connecting the inside of the intestine to the outside of the belly button. This affects the digestive system and can cause symptoms like abdominal pain, discharge from the navel, or sometimes infection. It occurs because the body does not properly close this connection during fetal development. The condition can lead to complications such as intestinal obstruction or infection if not identified. It is most often noticed in newborns or young children but can sometimes be found later in life.

Patent Vitelline Duct is a congenital anomaly characterized by the persistence of the vitelline duct, which normally obliterates during embryogenesis by the 7th week of gestation. This results in a persistent fistulous tract between the ileum and the umbilicus. The core pathology involves failure of involution of the vitelline duct, leading to a direct communication between the intestinal lumen and the external environment. Clinically, it presents with umbilical discharge, which may be feculent or serous, and can be complicated by infection, umbilical granuloma, or intestinal obstruction. It is important to differentiate this from other vitelline duct remnants such as Meckel diverticulum or fibrous bands. The condition is significant because it can cause recurrent infections and may require surgical intervention to prevent complications.
