Contributed by: Children's Hospital Omaha, Radiologist, Omaha Childrens, Creighton University and UNMC, Nebraska, USA.
Patient: 2 day old male

2-day old male who was found to have four ostia at the
time of insertion of umbilical arterial and venous catheters.
The study was done to evaluate for patent omphalomesenteric duct.

Under fluoroscopic guidance a total of 5.0 ml Omnipaque 300
contrast was injected through the umbilical catheter,
opacifying multiple loops of non-dilated small bowel located
within the left hemi-abdomen. There is retrograde
opacification of a small tract leading to the umbilicus, which
most likely represents a patent omphalomesenteric duct. The unusual
aspect of this lesion, however, is the fact that the
communication appears to be with the more proximal appearing
ileum, which is definitely located to the left of the midline.


Patent Omphalomesenteric Duct.


Congenital Omphalomesenteric Anomalies- Patent Omphalomesenteric Duct

- Other vitelline duct anomolies include Meckel's diverticulum (90%), Umbilical (vitelline) sinus, and umbilical (vitelline)
- Presentation: Neonatal umbilical discharge or additional umbilical ostia identified at birth
- Differential Diagnosis: Granulation tissue, retained umbilical cord elements, and infection or patency of urachal or omphalomesenteric ducts
- Imaging: Fluoroscopic sinus tract study for visualization of fistulous tract between umbilicus and bowel. Generally, tract opens into distal ileum, although may open into more proximal ileum, appendix or cecum. Also pelvic sonogram should be performed to evaluate for patent urachus.
- Cases of concommitant presentation of patent omphalomesenteric duct and urachus have been reported.
- Treatment: Surgical resection of fistula tract to the bowel with ileal reanastamosis.
