Introduction: Umbilical cord hernia (UCH) is an uncommon congenital abdominal wall defect that is frequently misdiagnosed as omphalocele minor, resulting in underrecognition and risk of preventable complications. Although considered a benign anomaly with favourable outcomes, delayed or missed diagnosis may lead to iatrogenic visceral injury at birth. We present a caseseries highlighting the diagnostic challenges, spectrum of contents, and uncommon associations of UCH.
Case presentation: A retrospective review was conducted of six neonates managed over four years at a tertiary pediatric surgical center. All presented within the first three days of life with membrane-covered herniation at the base of the umbilical cord; none were detected antenatally . Meckel’s diverticulum was the most frequent sac content (50%), with additionalfindings including appendix, caecum, terminal ileum, and a rare case of isolated hepatic herniation. One neonate presented with intestinal obstruction and perforation, while another developed necrotizing enterocolitis requiring ileostomy and intensive care support. An unusual association with tracheoesophageal fistula and esophageal atresia was observed. All patientsunderwent primary repair via an umbilical approach, and no recurrences were noted on followup.
Conclusions: UCH exhibits diverse intraoperative findings and may present with rare associations. Antenatal recognition remains limited but is crucial to prevent cord-clamping injuries. Careful clinical differentiation from omphalocele is essential, as timely surgical management yields excellent outcomes.
