Caustic injury is not common in gastroenterology but serious. The corrosive effect of bases and hydroxides generally leads to mucosal injury which can be followed by acute esophagus perforation or, after emergency management, to esophageal fibrosis and stricture. Similarly, stenosing processes of distal stomach may be the end point of a corrosive effect of acids. At the present time unequivocally preferential leading diagnostic method is an early endoscopy till 4 hours after caustic injury. This method enables not only a precise diagnosis but is able to asses the stadium of severity of changes and evaluate therapy strategy. The management of caustic injury is multidisciplinary with participation of gastroenterologists, intensive therapy specialists, nutritionists, surgeons and others.
