Prolapsed urachal sinus with pyourachus in an infant

Latent vitellointestinal duct sinus presenting with massive lower gastrointestinal bleeding in an adolescent

A 12-year-old boy with a history, at birth, of a weeping pink fleshy lesion after his umbilical cord detached, requiring repeated chemical cauterisation, presented with massive lower gastrointestinal bleeding and required resuscitation and blood transfusion. Augmented Tc99m nuclear medicine scan confirmed ectopic gastric mucosa. The lateral view suggested its attachment behind the umbilicus. At exploration, a latent vitellointestinal duct sinus with ectopic gastric mucosal mass was found. Segmental resection of the sinus and mass excision with primary anastomosis and incidental appendicectomy was curative. Pink fleshy mass discharging coloured fluid at the umbilicus following detachment of umbilical cord should be considered a remnant of vitellointestinal duct unless proved otherwise. A pink lesion with yellowish discharge resistant to chemical cauterisation should raise the suspicion of embryonic structures. Latent vitellointestinal sinus is a new lesion in the spectrum of umbilical anomalies. Lateral view of the nuclear medicine scan is helpful in locating the site.

Neonatal prolapsed patent vitellointestinal duct

A case of a prolapsed patent vitellointestinal duct (PVID) in a 10-day-old neonate who presented with vomiting and poor weight gain with partial intestinal obstruction and a flower like pink, prolapsing lesion at his umbilicus has been reported. A limited contrast study through the tubular structure confirmed it to be a PVID. He underwent transumbilical exploration and resection and anastomosis uneventfully. Persistence of the vitellointestinal duct as a whole or part of it leads to a wide variety of anomalies-Meckel's diverticulum is the commonest lesion and a PVID is the rarest. Umbilical cord clamping flush with the abdominal wall may convert a Meckel's diverticulum prolapsing in the base of umbilical ring into a PVID. Careful assessment should be made for associated anomalies. Transumbilical exploration gives the best cosmetic and functional results.
