Esophagus perforation

Although ingestion is unlikely to occur in industrial use, as little as 1.0 ml of glacial acetic acid has resulted in perforation of the esophagus. ... 

If the patient has ingested a corrosive poison, such as a strong acid or alkali (e.g., drain cleaners), emesis increases the likelihood of gastric perforation and further necrosis of the esophagus. 

As lewisite is a vesicant, emesis is not recommended in those species that can vomit (dogs, cats, swine, and ferrets). Dilution with milk or water is recommended. Activated charcoal is not recommended as severe irritation/vesication of the esophagus or gastrointestinal tract is likely to occur. Endoscopy can be performed very carefully to determine the extent of injury. Esophageal perforation and/or stricture formation may occur. 

Liquid acetic acid in concentrations above 80 percent has the same destructive effect on the human skin as concentrated hydrochloric acid. Glacial acetic acid can cause perforation of the esophagus. 

Necrotic phase This phase occurs 1-4 days after injury. Cells die from coagulation of intracellular protein. Vascular thrombosis and bacterial invasion may worsen the underlying injury. The esophagus is especially vulnerable to perforation during this phase. 

In TEE, the transducer is advanced into the esophagus and rests j ust behind the heart. The transdncer also can be passed into the fundus of the stomach to obtain better images of the ventricles. Images are obtained in either the horizontal or vertical plane. This is a low-risk invasive procedure and does not require routine antibiotic prophylaxis for patients at risk of developing endocarditis. Complications such as esophageal tears or perforation, esophageal burns, transient... 

Radiographic evaluation of the GI tract often starts with plain films of the abdomen, which are straightforward, uncontrasted radiographs. Specific abdominal structures that may be identified include the kidney, ureters, and bladder (KUB) esophagus stomach intestine stones and vessels. Plain films are often used to evaluate abdominal pain. Clinicians frequently employ plain radiographic fluoroscopy to guide and position other instruments that are used to evaluate and treat GI disorders an example is the manipulation of dilation devices to treat esophageal strictures. Bowel obstruction and perforation are especially well identified by this technique. 

E. Button batteries usually cause serious injury only if they become impacted in the esophagus, leading to perforation into the aorta or mediastinum. Most cases involve large (25-mm diameter) batteries. If button batteries reach the stomach without impaction in the esophagus, they nearly always pass uneventfully via the stools within several days. 

Precautions A common air contaminant. Very irritating to skin, eyes, nose and throat. At full strength, may cause difficult breathing and pulmonary edema. Upon ingestion may cause hemorrhaging, perforation of the esophagus and stomach, and death.

Perforation of the G1 tract is mostly iatrogenic. Both stomach and esophagus can incidentally be perforated by feeding tubes. The treatment with prostaglandins in case of patients with a patent ductus of Botalli can also be complicated with a perforation... 

With the introduction of plastic-covered metallic stents for the palliation of malignant dysphagia, interventionists found that these devices were also very effective at closing fistulas and perforations. Metallic stents are better that plastic stents in this regard because they expand to the diameter of the esophagus and the covering material provides an effective seal over the defect (Watkinson et al. 1995b Do et al. 1993). 

The technique is very similar to the procedure for palliation of malignant dysphagia. Preprocedural esophagography should be performed with nonionic contrast medium to confirm the presence of the fistula or perforation and to identify its approximate location in the esophagus. With the patient in the left-lateral position, a catheter is passed into the esophagus to the site of the lesion. The exact location of the fistula or perforation is defined by the direct injection of contrast medium into the esophagus. The site is marked with the use of residual contrast medium at the site of the defect, bony landmarks, or a surface marker. 

Covered metallic stents provide effective treatment for malignant flstulas and perforations. The clinical success rates are very high and most patients derive relief from symptoms of aspiration or debilitating thoracic sepsis. Patients with recurrent flstulas or leaks may be treated by additional overlapping stents in most cases. Metallic stents placed in the airways may be useful for some patients with a dilated esophagus, very high fistulas, or airway obstruction due to local invasion by esophageal tumors.
