A 28-week premature neonate on day 10 develops abdominal distension, bloody stools, bilious vomiting, and temperature instability. An abdominal X-ray shows pneumatosis intestinalis. Which finding on abdominal X-ray would indicate IMMEDIATE surgical consultation?

• A Portal venous gas
• B Fixed dilated bowel loop for >24 hours
• C Diffuse pneumatosis intestinalis
• D Pneumoperitoneum ✓

Explanation

Necrotizing enterocolitis (NEC) is suspected with pneumatosis intestinalis; however, pneumoperitoneum (free air under the diaphragm) indicates intestinal perforation, which is an absolute indication for immediate surgical intervention — specifically neonatal laparotomy (or peritoneal drainage in extremely unstable infants). Portal venous gas and fixed dilated bowel loops are relative indications and clinical deterioration markers suggesting progressive NEC (Bell stage IIB/III), but they do not mandate immediate surgery as clearly as pneumoperitoneum does. Diffuse pneumatosis alone is managed medically unless perforation occurs.
