Frequent postoperative gas expansion of the abdominal drain bag for a case of idiopathic neonatal pneumoperitoneum: A case report

This case demonstrated that laparotomy is not a true routine in neonates with idiopathic pneumoperitoneum if a timely diagnosis is established. Future research is still necessary to understand the source of the free gas in the abdomen, as well as the underlying causes of delayed postoperative gas underdiaphragm and postoperative abdominal drain bag gas expansion.
