Pneumoperitoneum in infants without gastrointestinal perforation

Area of Science:

• Neonatal Medicine
• Pediatric Surgery
• Diagnostic Imaging

Background:

• Pneumoperitoneum typically signifies gastrointestinal perforation, necessitating urgent surgical intervention (laparotomy).
• Critically ill infants with severe respiratory distress present a unique challenge in diagnosing the cause of pneumoperitoneum.

Observation:

• Ten infants with severe respiratory distress developed pneumoperitoneum without evidence of gastrointestinal leak.
• Clinical examination and radiographic studies, including paracentesis and gastrointestinal x-rays, ruled out perforation in these cases.

Findings:

• Three infants survived respiratory distress and showed no subsequent gastrointestinal issues.
• Autopsies of five infants who died from pulmonary disease revealed no gastrointestinal pathology, despite pneumoperitoneum.

Implications:

• Distinguishing "medical" pneumoperitoneum from "surgical" pneumoperitoneum is crucial in neonates with respiratory distress.
• Clinical and radiographic correlation can help avoid unnecessary laparotomies in this vulnerable population.
• Conservative management may be a viable option for select cases of non-surgical pneumoperitoneum in neonates.
