## Correct Answer: A. Feeding jejunostomy Sodium hydroxide (NaOH) is a strong alkali that causes liquefactive necrosis—a deep, penetrating injury that destroys the full thickness of the esophageal wall, leading to severe stricture formation and complete dysphagia. In acute caustic ingestion with complete dysphagia, the priority is nutritional support while the esophagus undergoes healing and fibrosis (typically 3–6 weeks). Feeding jejunostomy is the gold standard because it: (1) bypasses the damaged esophagus entirely, (2) allows direct nutrient delivery to the small bowel, (3) is placed via a simple percutaneous or open technique, and (4) can be maintained long-term if stricture becomes irreversible. Early feeding jejunostomy prevents malnutrition, sepsis, and aspiration during the acute inflammatory phase. Esophageal reconstruction (esophagojejunostomy) or other definitive procedures are deferred until the acute phase resolves and the extent of stricture is fully demarcated (usually 4–6 weeks post-injury). This staged approach—immediate nutritional support via jejunostomy, followed by delayed reconstruction if needed—is the standard of care per Indian surgical guidelines and Bailey & Love. ## Why the other options are wrong **B. Stent placement** — Stent placement is contraindicated in acute caustic injury because the esophageal wall is acutely inflamed, friable, and undergoing necrosis. A stent would cause further mucosal damage, perforation, and migration. Stents are considered only in chronic strictures (weeks to months later) and only if stricture is refractory to repeated dilations—not in the acute phase with complete dysphagia. **C. Gastrojejunostomy** — Gastrojejunostomy bypasses the esophagus but still requires gastric integrity and function. In severe caustic ingestion, the stomach may also be damaged (though less commonly than the esophagus). More importantly, gastrojejunostomy does not address the esophageal injury and is a more complex procedure than feeding jejunostomy. Jejunostomy is preferred because it is simpler, safer, and provides direct small-bowel feeding. **D. Esophagojejunostomy** — Esophagojejunostomy is a definitive reconstructive procedure reserved for chronic, irreversible esophageal strictures after the acute phase has resolved (4–6 weeks post-injury). Performing it acutely in a patient with ongoing inflammation, necrosis, and edema risks anastomotic leak, sepsis, and death. It is premature and inappropriate in the acute setting; feeding jejunostomy must precede any reconstruction. ## High-Yield Facts - **Sodium hydroxide causes liquefactive necrosis**—deep, full-thickness esophageal injury with rapid stricture formation, unlike acids which cause coagulative necrosis. - **Feeding jejunostomy is the acute-phase nutritional bridge** in complete dysphagia from caustic ingestion; it bypasses the damaged esophagus and prevents malnutrition and aspiration. - **Esophageal reconstruction (esophagojejunostomy) is deferred 4–6 weeks** until acute inflammation resolves and stricture extent is fully demarcated. - **Stent placement is contraindicated acutely** due to friable, necrotic mucosa; it is considered only in chronic refractory strictures after weeks of healing. - **Complete dysphagia post-caustic ingestion mandates immediate nutritional support**; feeding jejunostomy is placed within 24–48 hours to prevent sepsis and organ failure. ## Mnemonics **ACUTE CAUSTIC INJURY MANAGEMENT: 'JET' approach** **J**ejunostomy (immediate nutrition), **E**sophageal rest (no oral intake), **T**iming of reconstruction (4–6 weeks later). Use this to remember that jejunostomy is the first step, not reconstruction. **WHY NOT STENT ACUTELY: 'FRIABLE'** **F**riable mucosa, **R**isk of perforation, **I**nflammation ongoing, **A**cute phase contraindication, **B**etter to wait, **L**ate stenting if needed, **E**sophageal rest first. Stents belong in chronic strictures, not acute injury. ## NBE Trap NBE may pair "complete dysphagia" with "esophagojejunostomy" to lure students into choosing immediate reconstruction. The trap is forgetting that acute caustic injury requires staged management: nutrition first (jejunostomy), reconstruction later (after 4–6 weeks of healing). ## Clinical Pearl In Indian emergency departments, caustic ingestion (especially with cleaning products) is common in young females. The key bedside rule: if the patient has complete dysphagia and signs of full-thickness injury (vomiting, chest pain, subcutaneous emphysema), place a feeding jejunostomy within 24–48 hours and keep the patient NPO. Avoid the temptation to "fix" the esophagus immediately—let it heal first, then reconstruct if stricture persists. _Reference: Bailey & Love Ch. 62 (Esophagus); Harrison Ch. 286 (Caustic Ingestion)_
