<正>Dense and extensive esophageal strictures after caustic agent ingestion require surgical treatment. Colon

stomach and jejunum can be used to reconstruct esophagus. Here

we report an unusual patient with corrosive esophageal stricture who had received unsuccessful esophageal replacements twice at other hospitals. Colon interposition had been first performed 6 months after corrosive esophageal burn

but the colon graft necrosis occurred. Esophageal reconstruction had been carried out 10 years later in another hospital. However

the graft necrosis developed again 5 months later. A salvage operation was performed to remove the necrotic transplant in our hospital. Then as much food as possible had been given to expand the stomach through the gastrostomy since the procedure. The patient underwent esophagecto-my and concomitant gastroesophagostomy in the neck 1. 5 years later. Esophageal dilations had been performed to prevent recurrent anastomotic stricture for 1 year. He has eaten a normal diet since being discharged.
