Paediatric umbilical hernias typically close by the age of 4–5 without intervention; however, although complications are rare they must be recognised and acted on immediately. The umbilicus transmits the contents of the umbilical cord via a defect in the linea alba. The umbilical ring usually closes by contraction, the umbilical vein fibroses to become the round ligament of the liver, and attaches to the umbilicus. This provides anchorage to the umbilicus and protects against the formation of a hernia, however, a minority of patients are susceptible to hernia formation if this process does not occur correctly. Important risk factors for umbilical hernia formation include: Low birth weightAfrican ancestryTrisomy 13, 18 and 21Congenital hypothyroidismHurler's syndromeBeckwith-Wiedemann syndrome

CT scan of the abdomen shows distended small bowel loops with two focal areas of tapering in close proximity to the round ligament of the liver with intraluminal air–fluid levels, discrete lesser enhancement of the bowel wall compared to surrounding small bowel loops and focal infiltration of the adjacent mesenterial fat plane (Figure 1). These combined findings suggest a closed loop bowel obstruction.
