Abstract
Incarceration of an umbilical hernia during childhood is extremely rare. A 9-month-old boy was admitted to our hospital due to abdominal distension and coughs. His illness was diagnosed as umbilical hernia at birth, and was referred to our hospital for successional follow-up after reposition of incarcerated umbilical hernia at 8 months of age. He was discharged after one-day stay, but 11 days after discharge, an emergency surgery was needed due to failure of manual reposition for second incarceration. The diameter of the umbilical ring measured 15 mm in diameter and the incarcerated terminal ileum, cecum and appendix were repositioned after having performed a 5-mm-long excision of the fascia. The post-operative clinical course was uneventful.
We collected another thirteen pediatric cases of such incarcerated umbilical hernia in Japan and examined the pathogenesis in entity.
