Black Esophagus: A Rare Cause of Gastrointestinal Hemorrhage in the Emergency Department
In this case presentation of a 65-year-old man who presented to the ED for evaluation of a 1-week history of intermittent coffee-ground emesis and syncope, the authors review the literature about a rare, but potentially fatal diagnosis.
Case
A 65-year-old man presented to the ED for evaluation of a 1-week history of intermittent, exertional syncope and coffee ground emesis. His medical history was significant for hypertension, peripheral vascular disease, hyperlipidemia, and peptic ulcer disease. Although his social history was positive for alcohol use and abuse, the patient stated that he had not consumed any alcoholic beverages since the onset of nausea and vomiting.
A review of the patient’s systems was positive for lightheadedness upon standing and for palpitations. He had no prior history of melena, hematochezia, or syncope, but did report a previous history of upper gastrointestinal (GI) bleeding due to peptic ulcer disease and alcohol abuse.
The patient’s vital signs at presentation were: blood pressure (BP), 114/74 mm Hg; heart rate, 112 beats/min; respiratory rate, 15 breaths/min; and temperature, 97.7°F. Oxygen saturation was 97% on room air. On examination, the patient was conversant and oriented. He had dried blood around his mouth and chin from vomiting and appeared ill but nontoxic. His mucous membranes were pale. The cardiopulmonary examination was remarkable for tachycardia; however, the patient’s extremities were warm and his capillary refill time was normal. The rectal examination was notable for melenic stool, which was guaiac positive. During the patient’s course in the ED, he passed a large, melenic stool. The remainder of the physical examination was normal.
The chest X-ray was normal, but the electrocardiogram demonstrated sinus tachycardia. Laboratory studies were remarkable for the following:
hemoglobin (Hgb), 12.7 g/dL;
platelet count, 97 x 109/L;
sodium, 122 mmol/L;
chloride, 73 mmol/L;
potassium, 2.9 mmol/L;
blood urea nitrogen, 121 mg/dL;
creatinine, 1.89 mg/dL;
glucose, 297 mg/dL;
calcium, 7.9 mg/dL;
anion gap, 27 mmol/L;
total bilirubin, 1.6 mg/dL (mildly elevated);
direct bilirubin, 0.5 mg/dL;
aspartate aminotransferase, 41 IU/L; and
lactic acid, 5.5 mmol/L (elevated).
The patient’s international normalized ratio and activated partial thromboplastin time were normal. There were no recent prior laboratory studies available for comparison with current findings.
Two large bore intravenous (IV) lines were placed, and the patient was resuscitated with a bolus of 20 mL/kg of isotonic fluids. He was given 1 g of ceftriaxone and 80 mg of pantoprazole IV and was started on an infusion of octreotide. Meanwhile, the patient was consented for blood products and 2 U of packed red blood cells were crossmatched and held in reserve. He received potassium repletion of 60 mEq IV potassium chloride.
The emergency physician (EP) consulted with gastroenterology services. Due to concern for variceal bleeding and to control hemorrhaging, the gastroenterologist recommended emergent upper endoscopy. The upper endoscopy revealed circumferential necrosis of the distal third of the esophagus, which stopped abruptly at the gastroesophageal junction (Figures 1-3). Since no varices were demonstrated on endoscopy, octreotide was discontinued. The gastroenterologist recommended the patient receive nothing orally for 24 hours and that he continue to receive IV proton pump inhibitors (PPIs) and empiric antibiotics. The patient was admitted to the medical intensive care unit (ICU) for further care.
Following admission to the ICU, the patient did not have any additional episodes of hematemesis or melenic or bloody stools. However, his Hgb levels down-trended to 8.6 g/dL and his BP decreased to 84/63 mm Hg. He was transfused a single unit of packed red blood cells, after which BP normalized and Hgb stabilized at 9.5 g/dL. The patient’s diet was advanced on hospital day 1 to clear liquids and then solid foods, and he was discharged home on hospital day 2 with prescriptions for pantoprazole 40 mg twice daily and ranitidine 300 mg nightly and with close primary care and gastroenterology follow-up.
Discussion
Black esophagus, also referred to as acute esophageal necrosis (AEN) or necrotizing esophagitis, is an uncommon, but life-threatening cause of GI bleeding.1 First described by Brennan2 during a patient autopsy in 1967, black esophagus remained a postmortem finding until its first description on endoscopy by Goldenberg et al3 in 1990.With the increased use of endoscopy, black esophagus has been more commonly described in case reports and case series but remains an extremely rare diagnosis, with an incidence of 0.008% to 0.2%.4-7 A single study by Yasuda et al8 demonstrated a surprising incidence of AEN in 6% of patients undergoing upper endoscopy for upper GI hemorrhage.
Patients with black esophagus typically present for evaluation as a result of GI bleeding, which occurs in 65% to 90% of cases.9,10 This condition is more common in elderly patients with a disproportionately higher incidence in men, who represent approximately 80% of cases. A variety of comorbidities are associated with AEN, most commonly diabetes mellitus, malignancy, hypertension, renal insufficiency, heart disease, and duodenal ulcer.5,10 In a recent case series by Gurvits et al,11 tachycardia or hypotension was observed in 90% of cases.
Diagnosis
Black esophagus is defined by diffuse, circumferential necrosis of the esophagus with preferential involvement of the distal third of the esophagus that abruptly stops at the gastroesophageal junction, and in the absence of caustic ingestion.12 The predilection toward involvement of the distal esophagus is thought to be due to its relatively poor perfusion. Blood flow to the distal esophagus is highly variable, but typically occurs through the left gastric and left inferior phrenic arteries. This is believed to result in a “watershed region” that creates a susceptibility to insult.7,13 Histologically, there is necrosis of the mucosa and submucosa, inflammation of the muscle fibers, and occasional thrombosis of blood vessels.4 However, gross findings alone are sufficient for diagnosis, and biopsy is not mandatory.1,14
Etiology
The etiology of acute esophageal necrosis is not well understood. The prevailing theory is that the combination of an ischemic insult and reflux of gastric contents leads to mucosal destruction. The watershed distribution of blood flow to the distal esophagus is thought to predispose patients to ischemia or thrombosis.5,7,10 As previously mentioned, a recent series by Gurvits et al11 demonstrated that 90% of patients with black esophagus also develop tachycardia or hypotension. Further, many of the comorbid conditions noted in cases of AEN are characterized by a tendency toward malperfusion or thrombosis.
Management
The mainstay of managing black esophagus in the ED is aggressive fluid resuscitation, bowel rest, and treatment with IV PPIs. Antibiotics are not indicated unless the patient has an infection, is immunocompromised, continues to decompensate despite adequate IV fluid resuscitation, or has an esophageal perforation.7,11 In practice, the necessity of early antibiotic therapy may be unclear in the ED due to other considerations in the differential diagnosis; therefore, it is prudent to treat the patient empirically until these etiologies can be ruled out. Some clinicians recommend sucralfate due to its ability to bind pepsin and stimulate mucus secretion which theoretically prevents further esophageal injury.4 The initiation of sucralfate should be deferred until after endoscopy.
Esophageal strictures are the most common complication of black esophagus, developing in 16% to 25% of cases. Due to underlying disease, AEN is associated with a high-mortality of 12.5% to 36%.4,11 Mortality as a direct result of esophageal necrosis is less than 6%.10 Complications of black esophagus include perforation and mediastinitis, both of which are indications for emergent surgical intervention.1,15Emergency physicians traditionally manage GI bleeding with conservative measures and early involvement of gastroenterology services. Failure of patients to respond to traditional resuscitative measures may signal mediastinitis and require immediate surgical intervention. This infrequent diagnosis represents a significant deviation from the typical presentations seen by EPs in standard practice; for this reason, EPs should be aware of the signs and symptoms associated with black esophagus and consider it in the differential diagnosis of patients presenting with GI bleeding.
Summary
Emergency physicians are often the first providers to care for patients with an upper GI hemorrhage. While the mainstay of treatment of hematemesis is resuscitation with intravenous fluids and blood products, EPs must be aware of the potential etiologies that may change management. Black esophagus is a rare but important cause of hematemesis—a condition that can lead to esophageal perforation and mediastinitis. In cases wherein patients fail to respond to appropriate resuscitation, subsequently decompensate despite resuscitation, or appear septic, EPs should consider IV broad-spectrum antibiotics and surgical consultation.
