Clinical spectrum of neonates presenting with pneumoperitoneum: A retrospective study.

Background: Neonatal pneumoperitoneum is attributed, in most of the reported cases, to necrotising enterocolitis (NEC). There are also other causes leading to free intraperitoneal air. The aim of this study is to describe the clinical spectrum, causes, management and outcome of neonates admitted with pneumoperitoneum in the paediatric surgery unit of a university hospital.
