PY - 2013 T2 - Neonatology: Management, Procedures, On-Call Problems, Diseases, and Drugs, 7e AB - A pneumoperitoneum (an abnormal collection of free air in the peritoneal cavity) is seen on an abdominal radiograph. The air can be secondary to perforation of the gastrointestinal (GI) tract (most common), from the respiratory tract, or secondary to iatrogenic causes. Necrotizing enterocolitis (NEC) with perforation is the most common cause of a pneumoperitoneum in the neonate. A neonate with a pneumoperitoneum requires immediate evaluation and treatment, as early recognition is important in successful management.
