Modified Bell's Staging for Necrotising Enterocolitis

Modified Bell's classification (Walsh & Kliegman 1986) of necrotising enterocolitis severity in neonates. Stages IA/IB (suspected) → IIA/IIB (definite, mild/moderate) → IIIA/IIIB (advanced, ill/perforated).

Score interpretation

Stage I — Suspected NEC 1–2

→ NPO ×3 days; OG tube on free drainage; IV fluids; broad-spectrum antibiotics (e.g. amoxicillin + gentamicin + metronidazole); serial AXR and FBC; surgical review on standby.

Stage II — Definite NEC 3–4

→ NPO 7–14 days; TPN; antibiotics ≥10 days; surgical review; serial AXR (lateral decubitus) every 6 h; correct platelets/coagulation; transfer to NICU with surgery on-site if not already.

Stage III — Advanced NEC 5–6

→ Urgent paediatric surgical involvement; ventilation, inotropes as needed; correct DIC and acidosis. Stage IIIB (perforation): emergency laparotomy or peritoneal drain (if extremely preterm/unstable). Long NPO, TPN, prolonged antibiotics.
