omphalomesenteric duct sinus

OMD sinus

An OMD sinus should be suspected when mucus discharge is noted in the presence of an umbilical polyp or granuloma.

Patent OMD may be identified early in the neonatal period due to persistent feculent discharge.However, cysts and sinus tract may require additional evaluation, including ultrasonography and fistulography.

Management involves surgical exploration to exclude associated OMD or urachal remnants and excision of the duct.
