Pneumoperitoneum is a surgical emergency. Commonest cause in a neonate is hollow viscus perforation either secondary to Neonatal enterocolitis (NEC) or spontaneous perforation. The usual management of this is an exploratory laparotomy. We report 2 rare cases of pneumoperitoneum, one with pneumoscrotum, secondary to air leak (pneumothorax) in the congenital diaphragmatic hernia. Both babies were managed with chest drain, with the resolution of pneumoperitoneum preoperatively.
