The severity of alkaline esophagitis due to sodium hypochlorite ingestion is variable and the findings of endoscope within 48 hours of ingestion are reported to be associated with its prognosis. We report a good recovery case of grade 2B of alkaline esophagitis, which was treated with close observation. The patient was 59-year old man. He was found lying on the bed by his wife, after drinking bactericidal agents (Jianok) and kitchen cleaner (Magiclean) for suicide attempt. After his trachea was intubated, he underwent upper gastrointestinal scope, which displayed circumferential ulcers at the lower esophagus. He was diagnosed as having a Grade 2B alkaline esophagitis, which was associated with a higher probability of stricture or perforation. On the 14th day of the admission, the 2nd endoscope was performed and no esophageal strictures were detected. He was extubated and started oral feeding on the 15th day. After that, his hospital course was uneventful and was discharged on the 18th day. 6 months have passed since he left hospital. No esophageal strictures were detected so far.
