Match each esophageal disorder to its classic clinical or diagnostic hallmark.

  • AchalasiaFailure of lower esophageal sphincter relaxation and absent distal peristalsis
  • Zenker diverticulumPosterior mucosal herniation presenting with halitosis and regurgitation of undigested food
  • Diffuse esophageal spasmSimultaneous, uncoordinated contractions with a 'corkscrew' appearance on barium swallow
  • Eosinophilic esophagitisEndoscopic visualization of stacked circular rings and white exudates in an atopic patient

Cevap

Achalasia matches with failed lower esophageal sphincter relaxation. Zenker diverticulum matches with posterior mucosal herniation and halitosis. Diffuse esophageal spasm matches with uncoordinated contractions (corkscrew appearance). Eosinophilic esophagitis matches with stacked circular rings in an atopic patient.
Each esophageal disorder has a distinct pathophysiology and classic diagnostic finding. Achalasia involves loss of myenteric plexus ganglion cells (failed sphincter relaxation). Zenker diverticulum is a herniation above the upper esophageal sphincter. Diffuse esophageal spasm is a motility disorder with normal sphincter tone but uncoordinated contractions. Eosinophilic esophagitis is an immune-mediated condition associated with atopy and characteristic endoscopic rings.

Adım Adım Çözüm

1
Analyze the pathophysiology of Achalasia.
Identify it as a loss of inhibitory ganglion cells leading to absent peristalsis and failure of lower esophageal sphincter relaxation.
This directly matches the manometric findings of Achalasia.
2
Identify the anatomical defect in Zenker diverticulum.
Recognize it as a herniation of mucosa through Killian triangle, trapping undigested food and causing halitosis.
This connects the structural abnormality to the classic clinical presentation.
3
Recall the diagnostic hallmarks of Diffuse Esophageal Spasm.
Link the condition to simultaneous, uncoordinated contractions that create a corkscrew appearance on barium swallow.
This distinguishes it from other motility disorders like Achalasia.
4
Evaluate the classic presentation of Eosinophilic Esophagitis.
Associate the condition with atopic patients and endoscopic findings of stacked rings (trachealization) and white exudates.
This confirms the diagnosis based on endoscopic and patient demographic hallmarks.
