CAUSTIC INGESTION IN ADULTS
CAUSTIC INGESTION IN ADULTS — the modern approach is increasingly CT-CENTRED
Severe caustic ingestion is uncommon—but when a large amount of a strong acid or alkali is swallowed, injury can progress from mucosal burns to full-thickness gastrointestinal necrosis.
A major message from this 2026 review:
Do NOT worsen the chemical injury while trying to treat it.
🚨 FIRST PRIORITY: AIRWAY
Significant caustic ingestion can produce progressive oropharyngeal and laryngeal edema, making airway management increasingly difficult.
👉 Assess the airway early and anticipate deterioration.
When airway compromise is developing, securing the airway before severe edema develops may be crucial.
❌ What should NOT routinely be done?
The review specifically warns against:
Induced vomiting → repeat chemical exposure
Activated charcoal → not useful for the predominant local corrosive injury
Blind nasogastric tube insertion → may aggravate injured tissue
The primary injury is caused by local chemical reaction, not systemic absorption.
🧪 Which ingestions are particularly concerning?
The most severe injuries are associated with intentional ingestion of large volumes of strong corrosives, particularly:
pH <2 or >12
The review particularly identifies caustic soda and hydrochloric acid among agents warranting concern for ICU-level management.
🔄 THE IMPORTANT 2026 SHIFT: CT rather than routine early endoscopy
Historically, early upper GI endoscopy played a central role in grading caustic injury.
This review describes a major change toward:
CONTRAST-ENHANCED CT of the neck, chest, abdomen and pelvis
for severity assessment in the majority of patients—and certainly those with significant ingestion.
CT helps identify transmural necrosis and guide the need for surgery.
🔪 CT-GUIDED SURGERY
The key distinction is:
Lower-grade injury → predominantly conservative management
versus
Grade 3 transmural injury → RESECTION
According to the review, a CT-guided selective surgical strategy substantially reduces unnecessary esophagectomy and is associated with lower mortality and greater subsequent eating and breathing autonomy among ICU patients.
👉 Not every severe-looking ingestion requires esophagectomy—the critical question is transmural necrosis.
💊 Can corticosteroids prevent strictures?
This remains controversial.
The evidence for pharmacological prevention of esophageal stricture is poorly established.
Only small and conflicting randomized trials of corticosteroids exist, while evidence supporting other adjunctive therapies remains inadequate.
Steroids are therefore not a proven universal solution for stricture prevention.
⏳ The late problem: ESOPHAGEAL STRICTURE
Esophageal stricture is the most common late complication, occurring in approximately:
1 in 4 patients
Long-term malignant transformation is another concern, supporting lifelong surveillance after significant caustic injury.
🧠 Postgraduate Pearl
Think of caustic ingestion as:
AIRWAY → DEFINE AGENT → DON'T INDUCE VOMITING/CHARCOAL/BLIND NG → CONTRAST CT → ASSESS TRANSMURAL NECROSIS → SELECTIVE SURGERY → LONG-TERM FOLLOW-UP
The modern question is no longer simply:
“What does the mucosa look like?”
It is increasingly:
“Is there TRANSMURAL injury?”
🎯 Take-home message
In significant adult caustic ingestion:
Protect the airway early.
Do not induce emesis, administer activated charcoal, or blindly insert an NG tube.
Use contrast-enhanced CT for contemporary severity assessment.
Reserve major resection for transmural necrosis.
And remember—the emergency may end, but stricture and long-term malignant risk remain.
