Abstract

Ingestion of caustic substance such as strong alkalies or acids may result in not only severe acute esophageal injury but also various degree of esophageal stricture lately. Though bougie dilation is more preferred in corrosive esophageal stricture; endoscopic balloon dilatation (EBD) is similarly useful in some situations including short stricture. Usually EBD can be done safely in this three short stricture; but major complication such as perforation may be developed rarely and result in serious outcomes. Though there are several studies about post EBD perforation; there is no report which comment the relationship between perforation site and dilation site. We experienced a case of post EBD perforation developed at distal to the dilation site in a patient with short web-like corrosive esophageal stricture. In conclusion; even in very short stricture; EBD should be done with extreme caution because perforation could be occurred at surrounding weaken area.
