Omphalomesenteric duct in a neonate with omphalocele minor

On primary supply following delivery of a hypotrophic preterm boy (gestational age 36 weeks, Apgar 8/9/10, birth weight 1010 g (<1st percentile)), an omphalocele minor (2.5x5 cm) was diagnosed with a central aperture (0.8 cm diameter) emptying meconium (figure 1). Laboratory assessment and organ screening were inconspicuous, and no associated congenital malformation was detected in the otherwise healthy patient. Subsequent laparotomy following physiological adaptation confirmed an omphalocele minor solely containing intestinal loops and identified an omphalomesenteric duct (OMD) opening on the top of the sac (figure 2). The OMD (0.4 cm diameter, 3.8 cm length) was arising from the terminal ileum presenting with a post ductal ileal stenosis (calibre difference 2.5:1). Segmental resection was performed, and ileal continuity was restored. No further intestinal anomalies were detected. Histopathology confirmed normal ileal wall architecture of OMD without tissue ectopia. Further clinical course was uneventful. The neonate passed stools on day 4 following...
