A case of Meckel's diverticulum is reported in an eight-day-old male b
aby, the youngest patient to have had this condition at National Taiwa
n University Hospital. The baby had been affected by bilious vomiting
of 3 days' duration and abdominal distension before being brought to t
he hospital. A perforated Meckel's diverticulum was found during emerg
ency laparotomy. The resected Meckel's diverticulum did not contain ec
topic tissue. The narrow lumen and narrow base of the diverticulum was
thought to be the cause of poor self-emptying and subsequent acute in
flammation and perforation.
