Corrosive esophagitis in children is usually caused by swallowing a detergent accidentally. Damage to the gastrointestinal wall caused by an alkaline substance is generally more severe than that caused by an acid. Corosive esophagitis caused by the intake of an alkaline solution therefore results in the ocurrence of severe esophageal stricture. The damage is more severe in the esophagus than in the stomach, because the acid neutralizes the alkali. The treatment is resection and reconstruction of the esophagus or conservatively by dilation using a bougie or balloon.
