A two-day-old girl was transferred to our hospital because of worsening nonbilious vomiting after birth. Abdominal X-ray showed massive free air in the abdominal cavity. Furthermore, abdominal ultrasonography revealed opacified ascites at Morrison’s pouch and a target sign at the right lower abdomen. As these findings suggested gastrointestinal perforation, owing to intussusception, an emergent surgery was performed. The inverted Meckel’s diverticulum was identified, and its oral side was perforated. Resection and end-to-end anastomosis were performed at the same time. After surgery, the patient had an uneventful course and was discharged at 17 days of age. Pathologically, no ectopic gastric mucosa or ulceration was observed at Meckel’s diverticulum. On top of the small-bowel-stenosis-induced inverted Meckel’s diverticulum, an increase in the intestinal pressure due to oral intake seemed to result in the perforation. There were no necrotic lesions around the perforation site, so one-stage anastomosis was possible.
