Oesophagitis, caustic ingestion and oesophageal injury

Also known as Oesophagitis, caustic ingestion and oesophageal injury · Button battery ingestion · Caustic (corrosive) oesophageal injury · Eosinophilic oesophagitis · Reflux oesophagitis · Oesophageal foreign body

Fellowship guide to paediatric oesophagitis and oesophageal injury, built around the button-battery emergency: the reflux, eosinophilic, infective and pill causes of oesophagitis; the liquefactive alkali versus coagulative acid mechanism of caustic ingestion with the Zargar endoscopic grading; and the lithium coin-cell button battery that generates hydroxide at its negative pole and burns through the oesophageal wall within two hours, with honey and sucralfate as the pre-removal mitigations, emergent endoscopic removal, and the aorto-oesophageal fistula that can exsanguinate a child days after the battery is out.

Red flags

  • A witnessed or suspected button battery in the oesophagus is a surgical emergency — a 20 mm lithium coin cell can burn through the mucosa within two hours, so it is removed endoscopically within two hours of ingestion, not observed
  • Drooling, refusal to feed, chest or throat pain, stridor or a coin-like opacity with a halo (double-ring) sign on X-ray in a toddler is a button battery until proven otherwise — do not wait for symptoms to declare themselves
  • New haematemesis, a sentinel bleed or massive bleeding in a child who has had an oesophageal button battery is an aorto-oesophageal fistula until proven otherwise and can exsanguinate within minutes — it occurs up to three weeks after the battery is removed
  • After caustic ingestion, never induce vomiting, never give a neutralising acid or alkali, and never pass a blind nasogastric tube — each re-exposes the oesophagus to the corrosive or risks perforation
  • Stridor, hoarseness or respiratory distress after caustic ingestion signals airway burn and impending obstruction — secure the airway early, before oedema makes intubation impossible

Overview & Definition

Oesophageal injury in a child spans two very different worlds that share one lumen. On one side is oesophagitis, the inflammation of the oesophageal lining from reflux, allergy, infection or medication — a chronic and usually treatable problem. On the other side is acute corrosive injury, where a swallowed caustic chemical or a lodged button battery burns the wall in real time. The whole skill lies in telling the slow inflammatory problem from the fast destructive one, because their timescales, dangers and management could not be more different. [7]

The single most important idea in this topic is that a lithium coin-cell button battery impacted in the oesophagus is a surgical emergency measured in hours, not days. Once lodged against the moist mucosa it completes an electrical circuit through the tissue, generates hydroxide at its negative pole, and produces a spreading liquefactive burn that begins within two hours. Everything else in this topic can wait for a clinic; a button battery in the oesophagus cannot. [1] [4]

How should a fellowship candidate frame oesophageal injury in a child?

Oesophageal injury divides into oesophagitis — the chronic inflammatory disorders of reflux, eosinophilic disease, infection and pill injury — and acute mechanical or chemical injury from a swallowed foreign body, caustic chemical or button battery. The framing that matters is timescale: oesophagitis is investigated and treated over days to weeks, while a caustic ingestion is an emergency of the first hours and a button battery impacted in the oesophagus is an emergency of the first two hours. Name the cause, then act on its timescale. [1] [7]

The two-hour rule for an oesophageal button battery

A 20 mm lithium coin cell lodged in the oesophagus can cause full-thickness mucosal necrosis within two hours of ingestion. A witnessed or suspected oesophageal button battery is removed endoscopically as an emergency within two hours, not admitted for observation. The child who is drooling, refusing feeds or has chest pain after an unwitnessed ingestion is treated as a battery until an X-ray proves otherwise. [1] [4]
