AbstractAbstract PDF
Acid ingestion can cause not only caustic injury on esophagus and stomach but also fatal outcome through systemic complications. We report the case of a patient who died early after severe caustic injury with strong acid. A 38-year-old man who ingested about 400ml of hydrochloric acid of unknown concentration was transferred to our hospital from a private clinic, in which he was managed with gastric irrigation through a nasogastric tube. He was complaining dyspnea and abdominal pain. Physical examination demonstrated tenderness and rebound tenderness on epigastric region. Severe metabolic acidosis and leukocytosis were noted. Radiological findings suggested perforation of gastrointestinal tract, although the physical signs were not typical. Endoscopy revealed caustic injuries of grade I on esophagus and of grade Ⅲ on stomach, which indicate more severe injury on the stomach than on the esophagus. Exploratory surgery was recommended but unfortunately not permitted by his family. Despite intensive measures, his vital signs deteriorated rapidly and he died 50 hours after the ingestion.

AbstractAbstract PDF
Caustic ingestion can produce a progressive and devastating injury to the esophagus and stomach, In the acute stage, perforation and necrosis may occur. Long-term complications include esophageal stricture, antral stenosis and the development of esophageal cancer. Endoscopy should be performed as soon as possible in all cases to evaluate the extent and severity of damage, unless there is evidence of perforation. Endoscopy is the diagnostic procedure of choice. However, when the endoscopy cannot be passed through due to esophageal stricture, upper GI barium studies may be useful as a follow-up measure and in the evaluation of complications. A 44-year-old man visited our hospital complaining frequent vomiting 1 hour after ingestion of unknown amount of hydrochloric acid. At the time of arrival, the patient's oral cavity was slightly swollen and erythematous. On the endoscopic examination fourteen hour after the caustic ingestion, marked swelling of the arytenoids and circumferential ulceration with brown and black pigmentation at the upper esophagus were observed. Four weeks after the caustic injury, upper esophageal narrowing was observed and then the scope could not be advanced to the stomach. Upper GI barium study performed at that time revealed diffuse luminal narrowing of the esophagus and concentric luminal narrowing from prepyloric antrum to pylorus with disturbance of barium passage. At a week after the Upper GI study, through endoscopic examination after bougie dilatation of the esophagus, barium impaction in the stomach and the pylorus was noticed.
