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.

Purpose: Though caustic injury of the upper digestive tract can lead to severe sequelae, there are few clinical studies on this subject. This study was undertaken to evaluate the clinical characteristics, the endoscopic findings and the risk factors of the upper digestive lesions in patient with caustic ingestion injury. Methods: We retrospectively reviewed the medical records of 137 patients who ingested caustic materials and who visited to our emergency room from January, 2000 to June, 2009. Results: The most common ingested agent was sodium hypochlorite (44.5%), followed by acetic acid (19.7%), hydrochloric acid (11.7%) and lye (8.0%). Ingestion for suicidal attempt (62.0%) was more frequent than accidental ingestion (30.7%). Grade IIa injury was the most frequent finding on endoscopy of the esophagus and Grade 1 injury was the most frequent finding on endoscopy of the stomach. For the late sequelae, there were 9 cases (6.6%) of esophageal stricture and 2 cases (1.5%) of gastric outlet obstruction. The initial signs and symptoms did not correlate with the development of stricture, but leukocytosis, and grade III injury were related to the risk of developing stricture. Conclusion: Caustic injury of the upper gastrointestinal tract is frequently observed on early endoscopy and it can cause significant late sequelae such as stricture. Therefore, it is necessary to evaluate these patients with regular follow up endoscopic examinations for the management of late sequelae.

Laundery detergent ingestions are generally considered to have minor consequences. But some detergent ingestions have severe consequences. Unlike household bleaches contain sodium hypochlorite, bleaching agents that contain sodium carbonate have the potential to cause significant mucosal damage to the gastrointestinal tract if ingested. Especially, when ingested in solid form of Sodium carbonate, corrosive injury is much heavier. Therefore, patient who ingest sodium carbonate peroxyhydrate need more intensive management than patient who ingest other bleaches. We experienced a case of serious caustic injury after ingestion of Sodium Carbonate Peroxyhydrate. We report this case with review of literature.

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.

Two cases of severe caustic injury of the hypopharynx, esophagus, and stomach are presented. Restoration of digestive continuity was accomplished by retrosternal isoperistaltic interposition of the transverse and left colon on the post-injury 73rd and 66th day respectively. The upper oro-colon continuity was made by a cervical approach, a vertical incision at the posterior hypopharyngeal wall, and interrupted one-layer sutures using 3-0 Dacron suture materials. The distal continuity was made by colojejunostomy between the transposed colon and proximal jejunum. There was no event after the operation in both cases. The posterior vertical hypopharyngotomy and hypopharyngocolostomy at the early post-injury period may be the preferred procedure to obtain normal deglutition in patients with esophageal stricture associated with hypopharyngeal injury.

Purpose: We investigated comparison of clinical characteristics and prognosis by initial endoscopic severity in caustic injury and then discussed predisposing factors which can be helpful in predicting the prognosis and determining the treatment. Methods: This study was a retrospective review of medical records from patients over the age of 15, who underwent initial endoscopy for caustic injury from April 2007 through November 2014. Patients were classified according to two groups based on the initial endoscopic finding by Zargar's classification: patients with grade 0, I, IIa at esophagus (low risk group) and patients with grade IIb, IIIa, IIIb at esophagus (high risk group). The two groups were then compared. Results: A total of 55 patients were included (low risk group [n=44] vs. high risk group [n=11]). Old age (p<0.001), large amount of ingestion (p<0.05), oropharyngeal symptoms (p<0.01), high SOFA score (p<0.001), high WBC count (p<0.05), low base excess (p<0.01), and HCO3 (p<0.05) were statistically significant factors in the high risk group. A poor prognosis was observed for hospital stay (p<0.001), ICU admission (p<0.001), mortality (p<0.01), and stricture (p<0.001) in the high risk group. Conclusion: Clinical characteristics including age, amount of ingestion, oropharyngeal symptoms, SOFA score, WBC count, base excess, and $HCO_3$ can be helpful in the decision to undergo initial endoscopy and risk assessment by initial endoscopic severity can be helpful in predicting prognosis and determining the treatment plan.

Organophosphates are used as herbicides. Glyphosate is one of the acidic organophosphate solution of pH4.8-6. We experienced a case of laryngeal injury after glyphosate caustic ingestion. He had a mild respiratory distress, and a laryngeal granuloma was observed in endoscopy. He received treatment with oral steroid and PPI for two weeks, the laryngeal granuloma and respiratory distress were nearly disappeared. Therefore, we expect this case report to be helpful the therapeutic formulations in the damage of larynx due to glyphosate.

Between Dec. 1958 and Oct. 1989, we had been experienced 14 cases of the esophageal corrosion carcinoma among 562 cases of corrosive esophageal stricture, which incidence was revealed 5.6 % of total esophageal carcinoma cases and 2.5 9o of total benign esophageal stricture cases. The age distribution was from 15 to 64 years, and the mean age was 45.6 years. Ten of the patients were women. The caustic agents were lye in 12 patients and hydrochloric acid in 2 patients. The latent time from injury to the development of carcinoma was from 12 years to 45 years, and the mean latent time was 29 years. In majority of cases, the developing site of carcinoma was just or just above the benign stricture portion of the esophagus. Corrective surgery were made in seven cases; three cases were made esophagectomy and esophagogastrostomy, and the other four cases were made esophagectomy and colon interposition. Palliative surgery including feeding gastrostomy were made in seven cases. All cases had a longstanding history of difficult oral swallowing especially at the site of stricture. We think chronic food irritations of stricture portion of the esophagus induced the development of corrosion carcinoma. In conclusion, we had to suspect possibility of carcinoma in patient with long standing history of benign esophageal stricture. So we recommended preoperative esophagoscopic biopsy in such cases.

배경: 부식제를 삼킨후 발생하는 인두부위의 협착은 수술로 쉽지않고, 수술후 정상적인 음식물의 섭취까지 많은 노력이 필요하다. 저자등은 이러한 환자들을 치험한 후 결과를 관찰하였다. 대상 및 방법: 1995년 8월부터 1998년 3월까지 부식성 협착이 심하게 진행된 6례의 환자에서 식도재건술을 하였다. 부식제의 음용후 식도 재건술까지의 기간은 3개월에서 2년 4개월까지 였다. 6례에서 모두 좌측 대장을 사용하였고, 5례에서는 흉골하경로로, 1례에서는 식도열공경로로 위치시켰다. 경부 문합은, 3례에서는 갑상연골을 부분절제하여 좌측 양배꼴동에 문합하였고, 3례에서는 하인두수축근의 후외측에 실시하였다. 결과: 수술후 합병증은 연하곤란 3례, 좌측 성대마비 1례였다. 경부 문합부위협착은 없었다. 교정술기로는 식도확장과 유리 공장이식 1례, 성문위 반흔띠절제 1례, 대장 점막절제가 1례있었다. 연하곤란이 발견된 3례의 환자에서는 연하훈련이 필요하였다. 모든 환자에서 9일째부터 303일째까지에서 정상적인 연하기능의 회복이 관찰되었다. 결론: 이상의 결과로 인두부터 심하게 협착이 진행되어 있는 부식성협착에서 인두-대장 문합술이 식도 재건술로 유용함을 알수 있었고, 연하의 기능이 정상과 달라짐으로 경우에 따라서는 장시간의 훈련이 필요하다는 것을 알수 있었다. 그리고, 위의 출구까지 손상되어 위의 저류기능을 유지할 수 없는 증례들에서, 인두-대장-공장 문합술이 식도재건술로써 대안이 될 수 있음을 확인하였다.
