Question

Difficulty: EasyGastroenterology and Hepatology

Match each classic esophageal disorder with its most characteristic clinical or diagnostic finding.

  • AchalasiaIncomplete relaxation of the lower esophageal sphincter and absent peristalsis
  • Boerhaave syndromeTransmural rupture of the distal esophagus, often presenting with subcutaneous emphysema
  • Mallory-Weiss syndromeLongitudinal mucosal lacerations at the gastroesophageal junction typically presenting with hematemesis
  • Diffuse esophageal spasmUncoordinated, simultaneous contractions of the esophagus causing a 'corkscrew' appearance on imaging

Answer

Achalasia matches with incomplete lower esophageal sphincter relaxation. Boerhaave syndrome matches with transmural esophageal rupture. Mallory-Weiss syndrome matches with longitudinal mucosal lacerations. Diffuse esophageal spasm matches with uncoordinated, simultaneous contractions.
Each esophageal disorder has a distinct, classic presentation. Achalasia involves the loss of myenteric plexus neurons leading to lower esophageal sphincter dysfunction. Boerhaave syndrome is a full transmural perforation that leaks contents into the mediastinum, requiring emergent intervention. Mallory-Weiss syndrome is a superficial mucosal tear at the gastroesophageal junction that causes bleeding but does not perforate the esophagus. Diffuse esophageal spasm involves uncoordinated smooth muscle contractions without lower esophageal sphincter dysfunction.

Step-by-Step Solution

1
Evaluate the underlying pathophysiology for each esophageal condition.
Identify that Achalasia and Diffuse esophageal spasm are motility disorders, while Boerhaave and Mallory-Weiss are structural injuries related to increased intragastric pressure.
Categorizing the diseases simplifies the matching process based on functional versus structural etiologies.
2
Differentiate the structural tears.
Determine that Boerhaave syndrome is a full-thickness (transmural) tear, whereas Mallory-Weiss syndrome is a partial-thickness (mucosal) tear.
This is the most critical distinction between the two vomiting-induced esophageal emergencies.
3
Differentiate the motility disorders.
Determine that Achalasia involves failed relaxation of the lower esophageal sphincter, whereas Diffuse esophageal spasm features uncoordinated contractions (corkscrew esophagus) with normal sphincter relaxation.
Sphincter tone and the pattern of peristaltic failure define the exact diagnosis for motility issues.
