Treatment of corrosive esophageal strictures by long-term stenting

Abstract

From 1975 through 1992, 932 patients with caustic esophageal burns were admitted to the author's institution. Deep circumferential burns were diagnosed esophagoscopically in 241 children within the first 48 hours postburn. Initial treatment consisted of periodic anterograde and/or retrograde dilations of the injured and scarring esophagus (n = 172). In 1989, a long-term stenting technique was introduced, and a total of 69 patients have been treated in this manner. The healing rates of patients treated with traditional therapy were compared with those of patients who had stenting, and a significant difference was noted (33% v 68%; P < .01). Failure among the stented group was attributable to poor patient compliance and to gastroesophageal reflux resulting from shortening of the esophagus during scar formation.
