Esophageal Achalasia01:27

Esophageal Achalasia

Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
Pyloric Obstruction01:11

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
Barrett Esophagus-I: Introduction01:21

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Summary

Dysphagia lusoria, caused by vascular compression of the esophagus, can present later in life. This case highlights a rare variant involving a right aortic arch and aberrant left subclavian artery, responsive to dietary changes.

Area of Science:

  • Medicine
  • Cardiology
  • Gastroenterology

Background:

  • Dysphagia lusoria is defined as difficulty swallowing due to vascular compression of the esophagus.
  • Embryologic anomalies of the arterial brachial arch system can lead to tracheo-esophageal symptoms, primarily dysphagia, in 30-40% of cases.
  • Diagnosis typically involves barium swallow and chest CT scans, with variable manometric findings.

Observation:

  • This report details a rare case of late-onset dysphagia lusoria.
  • The patient presented with a right aortic arch and an aberrant left subclavian artery.
  • Additional esophageal dysmotility, specifically with solid bolus transit, was identified.

Findings:

  • The patient's dysphagia was attributed to a rare vascular anomaly causing esophageal compression.
  • Esophageal manometry revealed age-related changes and dysmotility affecting solid bolus transit.
  • The condition manifested later in life, suggesting a potential role for age-related physiological changes.

Implications:

  • This case underscores the importance of considering vascular anomalies in the differential diagnosis of dysphagia, especially in late-onset presentations.
  • Understanding the interplay between vascular compression and esophageal motility is crucial for accurate diagnosis and management.
  • Dietary modification proved effective, suggesting a conservative management approach may be beneficial for select patients with dysphagia lusoria and associated motility disorders.
