Core Tip

Core Tip: This study shows a higher mortality rate in a spontaneous pneumoperitoneum (SP) group than pneumoperitoneum secondary to gastrointestinal perforation, contrary to previous studies. Additionally, neonates with SP were more likely to have thrombocytopenia and accompany pneumothorax and persistent pulmonary hypertension. Preterm infants were the most significant factor affecting its mortality. These distinctive clinical features should be considered in the management of SP.
