Acute esophageal necrosis complicated by refractory stricture formation.

ABSTRACT: Acute esophageal necrosis (AEN) is a rare presentation of severe esophageal injury. The optimal long-term management of complications related to AEN, particularly stricture formation, are not well defined. We report a case of AEN in a patient who presented with diabetic ketoacidosis (DKA) and had dysphagia due to refractory stricture formation after mucosal healing occurred. A 62-year-old male with diabetes mellitus presented with altered mental status. He was admitted for hypovolemic shock secondary to DKA and treated with vasopressors, fluid resuscitation, and insulin. After resolution of DKA, he reported persistent dysphagia. Upper endoscopy showed circumferential black mucosal discoloration throughout the entire esophagus that spared the gastroesophageal junction. He was diagnosed with AEN and was continued on a proton pump inhibitor and sucralfate with improvement in symptoms. Repeat endoscopy 4 weeks later showed a 10-cm benign-appearing stricture in the mid esophagus. He underwent dilation with temporary symptomatic relief; however, recurrence in symptoms has thus far necessitated a total of 10 repeat upper endoscopies, including repeat dilations along with local steroid injection therapy. AEN is a rare presentation of severe esophageal injury and is typically associated with severe hemodynamic compromise. Although most cases resolve with supportive care and mucosal healing, there is little information regarding prognosis and optimal management of complications, such as refractory esophageal strictures. We describe a case of AEN complicated by refractory symptomatic esophageal stricture despite several dilations and intralesional steroid injections and discuss our approach to treatment.

Radioembolization for hepatocellular carcinoma complicated by biliary stricture.

Project description:The authors present a case of radiation-induced biliary stricture following yttrium-90 ((90)Y) radioembolization for hepatocellular carcinoma. Biliary complications (e.g., biliary stricture, biliary necrosis, biloma) following radioembolization and other locoregional therapies are uncommon and usually managed conservatively. In instances when biliary injury is refractory to medical management, as in the case presented herein, endoscopic, percutaneous, or surgical intervention may be required. Timely diagnosis of biliary complications with correlation to liver function permits optimal clinical management of patients undergoing (90)Y radioembolization.

Benign esophageal stricture model construction and mechanism exploration.

Project description:Esophageal stricture is a debilitating condition that negatively impacts patients' quality of life after undergoing endoscopic mucosal resection (EMR). Despite its significance, this disease remains underexplored due to the lack of a stable animal model. Under direct visualization with choledochoscopy, we retrogradely damaged the esophageal mucosal layer through the gastrostomy to create a rat model of esophageal stricture. The development of histological defects in the mucosal layer was assessed over a 2-week period after model induction. Then the models were evaluated using X-ray barium radiography, Hematoxylin-Eosin, Masson's trichrome, Sirius red, and Victoria blue staining, multiphoton microscopic imaging. Additionally, the molecular mechanisms of esophageal stricture were explored by conducting RNA transcriptome sequencing, PCR, immunohistochemistry, and immunofluorescence staining. We successfully established fifteen rat models of esophageal stricture by injuring the mucosal layer. In the model group, the mucosal defect initially occurs and subsequently repaired. The epithelium was absent and was plastically remodeled by collagen during the acute inflammatory phase (Day 1), proliferation phase (Day 7), anaphase of proliferation (Day 10), and plastic remodeling phase (Day 14). We observed increased expression of COL1A1, acta2, FGF, IL-1, and TGF-β1 pathway in the model group. We established a highly repeatable rat model of esophageal stricture, and our results suggest that the mucosal defect of the esophagus is a critical factor in esophageal stricture development, rather than damage to the muscularis layer. We identified Atp4b, cyp1a2, and gstk1 as potential targets for treating esophageal stricture, while the TGF-β pathway was found to play an important role in its development.

Acute Esophageal Necrosis: An In-depth Review of Pathogenesis, Diagnosis and Management.

Project description:IntroductionAcute esophageal necrosis (AEN) is an uncommon but fatal cause of upper gastrointestinal bleeding. The complex pathophysiology of the disorder provides multiple points for intervention. Therefore, it is important to discuss the many multifaceted aspects of the disease.MethodsA scoping review was performed using PubMed, Google Scholar, and ClinicalTrials.gov. We reviewed literature from 1990 to 2021. The keywords used were 'acute esophageal necrosis', 'upper GI bleed', 'pathogenesis', 'EGD', 'prognosis'.Results and conclusionsThe review summarized findings of 46 studies. AEN usually targets older males who have underlying cardiovascular disease. The middle part of the esophagus is commonly involved. The pathogenesis of AEN depends on conditions that increase risk of mucosal damage such as ischemia, lack of mucosal protection and excessive gastric reflux. Some medications are also responsible for the disease. Esophagogastroduodenoscopy is usually the gold standard for diagnosis. Findings suggestive of AEN include darkened, sharply demarcated circumferential areas. Supportive measures, including bowel rest, fluid supplementation and proton pump inhibitors are the cornerstone of therapy. A high index of suspicion should be maintained in patients with chronic health problems presenting with signs and symptoms of upper gastrointestinal bleeding because AEN can carry an unfavorable prognosis in these patients.

Esophagectomy for esophageal stricture with systemic sclerosis: a case report.

Project description:BackgroundSystemic sclerosis (SSc) is an autoimmune disease characterized by frequent esophageal involvement. However, there are few reports on esophagectomy for esophageal strictures associated with SSc. Herein, we present a case of successful treatment of an esophageal stricture associated with SSc through subtotal esophagectomy.Case presentationA 53-year-old female patient was diagnosed with SSc, interstitial pneumonia, and gastroesophageal reflux disease (GERD). The patient developed an esophageal ulcer and benign stricture that required a subtotal esophagectomy 10 years after the diagnosis. Histopathological findings revealed thinning of the muscle layer, a characteristic feature of SSc. The patient was free of dysphagia or regurgitation.ConclusionsAn esophagectomy is a valuable option for treating esophageal strictures in SSc. Therefore, surgical approaches should be established for patients with SSc.

Treatment of refractory vasospastic angina complicated by acute pulmonary oedema with levosimendan: a case report.

Project description:BackgroundVasospastic angina (VA) is an important cause of chest pain and patients often have 3- to 6-month clusters of recurrent attacks, separated by relatively asymptomatic periods. During these episodes the resulting myocardial ischaemia can lead to clinical complications of different severity, including acute myocardial infarction, acute heart failure, and cardiogenic shock. The management of severe and recurrent VA attacks is challenging, and no specific recommendations exist in recent cardiologic guidelines on the pharmacological strategy (inotropic/vasopressor agents) to adopt for this acute clinical setting.Case summaryWe present a case of recurrent episodes of VA complicated by acute pulmonary oedema and cardiogenic shock despite maximal tolerated therapy (intravenous calcium antagonist and nitrates) that was successfully treated with levosimendan.DiscussionLevosimendan rapidly reverted cardiogenic shock, acute pulmonary oedema, and mitral regurgitation caused by a refractory coronary spasm, contributing to persistent clinical stabilization. Further evidence and a longer follow-up are needed to support our observation on the efficacy of levosimendan in this specific clinical setting.

Acute Esophageal Necrosis in a Septic Patient with a History of Cardiovascular Disease.

Project description:Acute esophageal necrosis (AEN), or colloquially named "black esophagus," is a rare clinical condition often associated with ischemic injury to the esophagus secondary to splanchnic vasoconstriction during hypotensive episodes. We present a case of a 78-year-old man with extensive cardiovascular disease who was initially admitted for gallstone pancreatitis and possible cholangitis. His hospital course was complicated by possible sepsis secondary to aspiration pneumonia and hematemesis secondary to acute ischemic esophageal necrosis as noted on upper endoscopy. Interestingly, the patient only had a transient episode of hypotension (approximately 35 minutes) not requiring vasopressor support, which improved with fluid resuscitation, and endoscopic retrograde cholangiopancreatography (ERCP) done 3 days prior showed normal esophageal mucosa. Clinicians should be aware of the possibility of acute esophageal necrosis as a potential etiology of gastrointestinal (GI) bleed in patients with cardiovascular disease and sepsis.

Refractory status epilepticus complicated by drug-induced involuntary movements.

Project description:New onset refractory status epilepticus (NORSE) is a neurological emergency and difficult to treat condition. We report a case of involuntary movements resulting from thiopentone sodium infusion during the management of refractory status epilepticus. A young woman was admitted with fever and NORSE in the neurology intensive care unit. In addition to supportive measures, she was treated with intravenous lorazepam, phenytoin sodium, sodium valproate, midazolam and thiopentone sodium. While on thiopentone sodium, she developed involuntary twitches involving her upper limbs and face with EEG showing no evidence of ongoing status epilepticus. Because of the temporal relationship with thiopentone infusion, we tapered the dose of thiopentone sodium, which resulted in the disappearance of the movements. The patient recovered well with no recurrence of the seizures during the hospital stay.
