Purpose: Endoscopy has been recommended as a primary procedure for determining the extent of damage and prognosis in patients with caustic ingestions. Endoscopy within the first 24 hours has been suggested, however, such immediate endoscopy is not always possible. Therefore, we wanted to determine complications and possible delayed sequelae after the endoscopy performed dependent on time, including less than 24 hours and more than 24 hours, after ingestion of relatively high toxic caustic agents. Methods: From January 2005 to May 2013, 105 consecutive patients were diagnosed with caustic poisoning in the emergency department of the Wonju Severance Christian Hospital. Out of 95 patients who underwent endoscopy, while excluding 49 patients who ingested sodium hypochlorite and 15 patients due to insufficient data, 41 patients were ultimately included. We compared general characteristics, complications related to endoscopy, late sequelae, total admission length, and mortality between two groups. Results: Twenty eight patients (68.3%) were diagnosed with acid ingestion. Median endoscopy time was 17.8 (IQR 9.7-36.9) hours and performed in 16 patients (39%) after 24 hours. There were no complications, such as perforation and bleeding in either endoscopy within 24 hours group or endoscopy after 24 hours group. In addition, no difference in ingested materials, endoscopy grade, or late sequelae was observed between endoscopy within 24 hours group and endoscopy after 24 hours group. Conclusion: No difference in complications and late sequelae was observed between endoscopy within 24 hours group and endoscopy after 24 hours group when endoscopy was performed based on a clinician's assessment.

AbstractAbstract PDF
Nitrogen dioxide ($NO_2$), which produced during the process of silage, metal etching, explosives, rocket fuels, welding, and by-product of burning of fossil fuels, is one of major components of air pollutant. Accidental exposure of high level of $NO_2$ produces cough, dyspnea, pulmonary edema which may be delayed $4~12$ hours and, in $2~6$weeks, bronchiolitis obliterans. We experienced a case of acute pulmonary injuny induced by industrial exposure to high level of $NO_2$ during repair of $NO_2$ pipeline in a refinery. A 55-year-old man experienced nausea and severe dyspnea in 6 hours after $NO_2$ inhalation. Initial blood gas examination revealed severe hypoxemia accompanying increased alveolar-arterial O2 difference. Radiological examination showed diffuse ground glass opacities in both lung fields. Clinical symptoms and laboratory findings, including radiological study and pulmonary function test were improved with conservative treatment using inhaled oxygen and bronchodilator. and there was no evidence of bronchial fibrosis and bronchiolitis obliterance in chest high resolution computed tomography performed 6 weeks after exposure. Here, we report a case of $NO_2$ induced acute pulmonary injuny with a brief review of the relevant literature.
