[Severe caustic injuries of the esophagus: when to replace the esophagus].

From June 1985 to May 1998, 20 patients have been treated in our hospital by esophageal dilatations due to serious esophageal caustic stenosis. A retrospective analysis of these 20 patients was performed, evaluating age, sex, causative agent, number and time of dilatations, iatrogenic esophageal perforations, gastroesophageal reflux (GER) and psychological and social consequences. Follow-up has ranged from 1.5 to 14.5 years (mean = 8.07 years). The mean age at the time of accidental swallow was 42.2 months. The causative agent was dishwashing detergent in 11 patients and caustic soda in 9 patients. The mean of dilatations needed was 19.1 and the average duration of dilatations was 24.7 months. Seven patients had esophageal perforation during dilatation and none of them required surgical treatment. All patients had improvement of swallowing and an easier esophageal dilatation afterwards. Oral contrast studies demonstrated distortion of the esophago-gastric junction in the majority of patients. Ten patients were screened for GER with 24-hour esophageal pH monitoring in the first year postburn and it was pathological in 5. Antireflux surgery was carried out in 4 patients with a conspicuous improvement following surgery. Dilatations proved successful in 16 patients in less than two years, and in more than two years in 3 patients. The authors conclude that the majority of children with esophageal caustic stenosis can be managed successfully by esophageal dilatations, even with dilatation periods longer than two years or when an esophageal perforation occur during the procedure. The paramount importance of early diagnosis and treatment of GER is stressed.
