ABSTRACT
Case Presentation
We describe a case of a man who developed severe caustic injury of his upper gastrointestinal tract after ingestion of a commercially available 9.5% hydrochloric acidic cleaning solution. He rapidly deteriorated and required endotracheal intubation. He underwent several imaging modalities demonstrating his injuries and ultimately succumbed to his injuries.
Discussion
Acidic caustic ingestions may range in severity and uncommonly result in death. Diagnosis is most often achieved by esophagogastroduodenoscopy, although computed tomography may increasingly play a role in defining the extent of injury. Esophagogastroduodenoscopy findings are often assigned a Zargar grade, which guides management. Medical management of acidic caustic ingestion may include bowel rest, steroids, antibiotics, and proton pump inhibitors depending on the extent of injury, although surgery may be required if esophageal perforation occurs.
CASE PRESENTATION
A 63-year-old man presented to the emergency department (ED) via ambulance with recurrent hematemesis after an intentional ingestion of a commercially available 9.5% hydrochloric acid, toilet bowl cleaning solution. While initially stable, he rapidly deteriorated following arrival and was unable to tolerate his secretions and ultimately required endotracheal intubation for airway protection. He underwent computed tomography (CT) of his chest, abdomen, and pelvis (Image 1), which identified diffuse thickening of the proximal gastrointestinal (GI) tract without evidence of perforation. A pantoprazole infusion was initiated while gastroenterology and toxicology were consulted. A bedside esophagogastroduodenoscopy (EGD) was performed in the ED, which revealed Zargar grade 3B esophagitis and active bleeding from the duodenum (Image 2).
The patient was admitted to the intensive care unit for ongoing medical management. Repeat CT imaging revealed esophageal perforation with mediastinal and intra-abdominal free fluid (Image 3). Given the extent of the esophageal injury, the patient was not a candidate for esophagectomy and ultimately died despite aggressive medical management.
DISCUSSION
Hydrochloric acid ingestion resulting in death is rare. In 2019, the American Association of Poison Control Centers reported 184,677 exposures to cleaning products, which includes caustics. Of 16 deaths related to acidic ingestion, only two were from hydrochloric acid, and neither one was related to toilet cleaning products.
1
Acidic ingestions cause a coagulative necrosis in the GI tract. Severe oropharyngeal pain, odynophagia, and hypersalivation are commonly observed clinical features following ingestion, although, importantly, the degree of injury does not correlate with symptom severity.
2
While EGD remains the gold standard, the role of CT for diagnosis, prognostication, and surgical planning is expanding. In addition to diagnosis, EGD can be used to assign a Zargar grade of esophageal injury.
The Zargar grading system is widely used for caustic ingestion grading and guides further management.

Zargar grade 2A or less may be treated conservatively with bowel rest and supportive care. High-dose systemic corticosteroids are indicated for the prevention of strictures in Grade 2B lesions, while more severe injury may require surgical intervention. However, EGD has limited ability to detect the depth of necrotic injury, which may influence surgical planning.

Esophagogastroduodenoscopy is ideally performed within the first 48 hours from time of injury to minimize the risk of iatrogenic esophageal perforation and is contraindicated in instances of known viscous perforation.

Multiple grading systems to compare CT findings to EGD findings have been proposed; in one, CT grade I lesions correspond to Zagar grade 1–2A, while CT grade III corresponds to Zargar grade 3B.

Blind insertion of naso- or orogastric tubes is contraindicated, as this may result in further esophageal injury or perforation, but they can be placed under direct endoscopic guidance.

Antibiotics for identified sources of infection and proton pump infusions are reasonable with consequential injuries.
