Acute esophageal necrosis and liver pathology, a rare combination

Acute Esophageal Necrosis and Duodenal Disease in the Setting of Recently Initiated Chemotherapy

Introduction

Acute esophageal necrosis (AEN), commonly referred to as "black esophagus" or Gurvits syndrome, is a rare condition characterized by diffuse black mucosa in the distal esophagus. Most often, the patient is an older male with multiple comorbidities, presenting with upper gastrointestinal bleeding. The exact pathogenesis is unclear, but it is often thought to be secondary to acute vascular hypo-perfusion or ischemia of the esophageal mucosa in critically ill patients with certain secondary comorbid conditions such as renal insufficiency, diabetes mellitus, dyslipidemia, coronary artery disease, malnourishment, alcohol abuse, or association with an underlying malignancy.

Case Presentation

We present a case of AEN in a 78-year-old female following the recent start of a chemotherapy regimen with carboplatin and paclitaxel two weeks prior. The patient underwent EGD and was found to have AEN throughout the entirety of her esophagus with necrosis and eschars seen up to the second part of the duodenum. The patient initially improved after receiving blood transfusions, being made nil-per-os, and starting proton pump inhibitor (PPI) therapy, but she ultimately died given the severity of her clear cell uterine cancer and other comorbidities.

Conclusion

Although it is rare that initiation of chemotherapy leads to AEN, it should be considered as a potential etiology.

Acute esophageal necrosis: A systematic review and pooled analysis

BACKGROUND

Acute esophageal necrosis (AEN) is a rare entity with multifactorial etiology, usually presenting with signs of upper gastrointestinal bleeding.

AIM

To systematically review all available data on demographics, clinical features, outcomes and management of this medical condition.

METHODS

A systematic literature search was performed with respect to the PRISMA statement (end-of-search date: October 24, 2018). Data on the study design, interventions, participants and outcomes were extracted by two independent reviewers.

RESULTS

Seventy-nine studies were included in this review. Overall, 114 patients with AEN were identified, of whom 83 were males and 31 females. Mean patient age was 62.1 ± 16.1. The most common presenting symptoms were melena, hematemesis or other manifestations of gastric bleeding (85%). The lower esophagus was most commonly involved (92.9%). The most widely implemented treatment modality was conservative treatment (75.4%), while surgical or endoscopic intervention was required in 24.6% of the cases. Mean overall follow-up was 66.2 ± 101.8 d. Overall 29.9% of patients died either during the initial hospital stay or during the follow-up period. Gastrointestinal symptoms on presentation [Odds ratio 3.50 (1.09-11.30), P = 0.03] and need for surgical or endoscopic treatment [surgical: Odds ratio 1.25 (1.03-1.51), P = 0.02; endoscopic: Odds ratio 1.4 (1.17-1.66), P < 0.01] were associated with increased odds of complications. A sub-analysis separating early versus late cases (after 2006) revealed a significantly increased frequency of surgical or endoscopic intervention (9.7 % vs 30.1% respectively, P = 0.04)

CONCLUSION

AEN is a rare condition with controversial pathogenesis and unclear optimal management. Although the frequency of surgical and endoscopic intervention has increased in recent years, outcomes have remained the same. Therefore, further research work is needed to better understand how to best treat this potentially lethal disease.

Diagnosis and management of acute esophageal necrosis

Acute esophageal necrosis is a rare syndrome classically characterized by a striking endoscopic image of diffuse and circumferential black mucosal discoloration of distal esophagus, with an abrupt transition at the gastroesophageal junction and variable proximal extension. The typical patient is an older male with general debilitation and multiple comorbidities presenting with hematemesis or melena. The pathophysiology usually involves a combination of esophageal ischemia, backflow injury from gastric chemical contents and impaired mucosal reparative mechanisms associated with debilitated physical states. It may arise in the setting of hemodynamic compromise, diabetic ketoacidosis, hypothermia, alcoholic intoxication, trauma, inflammatory diseases, esophageal local infection, solid organ transplantation, postoperative status, drugs or acute gastric outlet obstruction, usually in the background of a chronic debilitating process, where the concurrent presence of multiple risk factors, including diabetes mellitus, hypertension, malnutrition, malignancy or alcohol abuse, places a patient at higher risk. The characteristic endoscopic appearance establishes the diagnosis. Biopsy is supportive but not required. Management is mainly supportive and consists of correcting coexisting conditions, fluid therapy, bowel rest, intravenous proton pump inhibitor therapy and red blood cell transfusion as needed. Although this is a serious life-threatening condition, appropriate treatment may result in a favorable outcome in the majority of patients.

Clinical presentations, management, and outcomes of acute esophageal necrosis: a systemic review

BACKGROUND

To review all the reported literature on acute esophageal necrosis.

RESEARCH METHODS

Databases were searched using the special Medical Subject Heading (MeSH) terms. All the available reported cases of acute esophageal necrosis were analyzed.

RESULTS

A total of 154 cases were identified and 130 cases were analyzed. The mean age of presentation was 61 years, and 70% of cases were males. The most common presenting symptoms were hematemesis in 66%, shock in 36%, melena in 33%, abdominal or substernal pain in 28%. The most common comorbidities reported were diabetes in 38%, hypertension in 37%, alcohol abuse in 25%, and chronic kidney disease in 16%. On upper endoscopy, 51% had a distal disease, 36% had pan esophageal, and only 2% had a proximal disease. 84% of patients were treated with IV Proton Pump Inhibitors, 22% received transfusions, 23% got antibiotics for underlying sepsis, 14% also received sucralfate, and 4% required surgery for treatment. The mortality rate was 32%, while perforation was reported in 5% and stricture formation reported in 9% of patients.

CONCLUSIONS

Patients with acute esophageal necrosis can have a favorable outcome if treated appropriately.

Comprehensive review of acute oesophageal necrosis

Acute oesophageal necrosis, also known as 'black oesophagus', is a rare condition characterised by the black discolouration of the oesophageal mucosa on endoscopy and involves the distal oesophagus in majority of cases but may also extend proximally. A number of conditions are found to be associated with it and it is thought to occur due to a combination of hypovolaemia and inadequate oesophageal protective mucosal barrier function. Gastric secretions may have a direct effect on the oesophageal mucosa. We present a case of a woman who presented with haematemesis and significant hypotension after a session of haemodialysis. Black oesophagus was confirmed on esophagogastroduodenoscopy. She was given two units of packed red blood cells and one unit of platelets, and started on a pantoprazole infusion. However, despite rigorous attempts at resuscitation the patient failed to recover.

Acute Necrotizing Esophagitis Followed by Duodenal Necrosis

Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved.

A case of black esophagus with histopathologic description and characterization

Black esophagus, or acute necrotizing esophagitis, is a blackening of the esophagus that is usually distal with a sharp demarcation at the gastroesophageal border. Black esophagus is known to the gastroenterology community; however, to our knowledge it is virtually unknown in the pathology literature with only a single instance described in 1967. It is thought to occur as a poorly elucidated ischemic phenomenon. We report a case of black esophagus in a 45-year-old woman with a history of cocaine and alcohol abuse who was found unresponsive after a vague 2-day illness. On autopsy examination, the esophagus was black with ischemic necrosis of the mucosa, submucosa, and muscularis propria including a diffuse acute inflammatory infiltrate and brown pigmentation limited to the mucosa. Positive periodic acid-Schiff and negative iron stains suggest that the pigment is lipofuscin, likely secondary to ischemia.

Esophageal infarction

Esophageal infarction or acute necrotizing esophagitis is a rare condition that has a dramatic endoscopic appearance of a "black esophagus." The esophageal involvement can vary from the distal third to the total esophagus. Excluding corrosive injury and other well-known rare causes of black esophagus, the etiology of this condition is unknown. Ischemia due to hypoperfusion state is thought to play a central role in the pathogenesis. The treatment is supportive with acid suppression and gastrointestinal rest. Mortality is high due to comorbid conditions.

Acute esophageal necrosis: a case series of five patients presenting with "Black esophagus"

Acute esophageal necrosis (AEN), also known as "Black esophagus", is a rare condition that typically presents as upper gastrointestinal hemorrhage. A retrospective chart analysis was conducted at two tertiary care hospitals over a three-year period (2005-2007) using a computerized inpatient database. Out of 9,179 upper endoscopies performed, five patients (0.05% prevalence) were found to have black esophagus. Their mean age was 44 years and the most common presentation was upper gastrointestinal bleeding. All five patients had comorbid conditions, most commonly coronary artery disease, diabetes mellitus, and renal insufficiency. Two patients died, but the cause of death was not related to AEN in either. In conclusion, AEN is usually seen in critically ill elderly patients with multiple comorbid conditions, particularly vascular disease, diabetes mellitus and azotemia.

Black esophagus: Acute esophageal necrosis syndrome

Acute esophageal necrosis (AEN), commonly referred to as “black esophagus”, is a rare clinical entity arising from a combination of ischemic insult seen in hemodynamic compromise and low-flow states, corrosive injury from gastric contents in the setting of esophago-gastroparesis and gastric outlet obstruction, and decreased function of mucosal barrier systems and reparative mechanisms present in malnourished and debilitated physical states. AEN may arise in the setting of multiorgan dysfunction, hypoperfusion, vasculopathy, sepsis, diabetic ketoacidosis, alcohol intoxication, gastric volvulus, traumatic transection of the thoracic aorta, thromboembolic phenomena, and malignancy. Clinical presentation is remarkable for upper gastrointestinal bleeding. Notable symptoms may include epigastric/abdominal pain, vomiting, dysphagia, fever, nausea, and syncope. Associated laboratory findings may reflect anemia and leukocytosis. The hallmark of this syndrome is the development of diffuse circumferential black mucosal discoloration in the distal esophagus that may extend proximally to involve variable length of the organ. Classic “black esophagus” abruptly stops at the gastroesophageal junction. Biopsy is recommended but not required for the diagnosis. Histologically, necrotic debris, absence of viable squamous epithelium, and necrosis of esophageal mucosa, with possible involvement of submucosa and muscularis propria, are present. Classification of the disease spectrum is best described by a staging system. Treatment is directed at correcting coexisting clinical conditions, restoring hemodynamic stability, nil-per-os restriction, supportive red blood cell transfusion, and intravenous acid suppression with proton pump inhibitors. Complications include perforation with mediastinal infection/abscess, esophageal stricture and stenosis, superinfection, and death. A high mortality of 32% seen in the setting of AEN syndrome is usually related to the underlying medical co-morbidities and diseases.

Acute oesophageal necrosis: a case report and review of the literature

AIMS

We discuss a case of acute oesophageal necrosis and undertook a literature review of this rare diagnosis.

METHODS

The literature review was performed using Medline and relevant references from the published literature.

RESULTS

One hundred and twelve cases were identified on reviewing the literature with upper gastrointestinal bleeding being the commonest presenting feature. The majority of cases were male and the mean age of presentation is 68.4 years. This review of the literature shows a mortality rate of 38%.

CONCLUSION

Acute necrotizing oesophagitis is a serious clinical condition and is more common than previously thought. It should be suspected in those with upper GI bleed and particularly the elderly with comorbid illness. Early diagnosis with endoscopy and active management will lead towards an improvement in patient outcome.

Acute esophageal necrosis and low-flow state

Acute esophageal necrosis (AEN), also called black esophagus, is quite exceptional. Endoscopic findings show circumferential black discolouration of the esophagus with or without exudates. The etiology of AEN is presently unknown and is assumed to be multifactorial. Distal esophageal involvement with proximal extension ending sharply at the gastroesophageal junction is the most common presentation. The present case report describes the clinical and endoscopic evolution of black esophagus observed in a patient with significant peripheral vascular disease, who was presented to the intensive care unit at the Hopital Saint-Francois d'Assise (Quebec City, Quebec). Through an extensive review of the literature, common underlying clinical conditions of patients diagnosed with AEN have been identified.

Acute esophageal necrosis: a rare syndrome

BACKGROUND

Acute esophageal necrosis, which presents as a black esophagus on endoscopy, is a rare disorder that is poorly described in the medical literature. In this study, we analyze all cases reported to date to define risk factors, clinical presentation, endoscopic features, histologic appearance, treatment, complications, outcome and etiopathogenesis of the disease and to describe a distinct medical syndrome and propose a staging system.

METHODS

We searched Medline and PubMed from January 1965 to February 2006 for English-language articles using the key words "acute esophageal necrosis," "necrotizing esophagitis," and "black esophagus."

RESULTS

A total of 88 patients were reported in the literature during the 40 years, 70 men and 16 women with an average age of 67 years. Patients were generally admitted for gastrointestinal bleeding and cardiovascular event/shock. Patients presented with hematemesis and melena in more than 70% of the cases. Upper endoscopy showed black, diffusely necrotic esophageal mucosa predominantly affecting the distal third of the organ. Necrosis was confirmed histologically in most cases. Complications included strictures or stenoses, mediastinitis/abscesses, and perforations. Overall mortality was 31.8%.

CONCLUSIONS

This study provides a structured approach to identifying risk factors, diagnosis, and pathogenesis of the acute esophageal necrosis. Risk factors include age, male sex, cardiovascular disease, hemodynamic compromise, gastric outlet obstruction, alcohol ingestion, malnutrition, diabetes, renal insufficiency, hypoxemia, hypercoagulable state, and trauma. Mechanism of damage is usually multifactorial secondary to ischemic compromise, acute gastric outlet obstruction, and malnutrition. Overall, acute esophageal necrosis should be viewed as a poor prognostic factor, associated with high mortality from the underlying clinical disease.
