Esophageal Dysphagia (Case 21)
Benjamin Ngo MD and John Abramson MD
Case: A 50-year-old man is encouraged by his wife to present for an evaluation of difficulty swallowing solid food that has progressively worsened over several months. He complains of occasional heartburn and is otherwise without significant medical problems. He has had an associated 15-lb weight loss.
Differential Diagnosis
Achalasia (motility disorders) |
Esophageal cancer |
Eosinophilic esophagitis |
Peptic stricture |
Schatzki ring (esophageal ring) |
We consider dysphagia and weight loss in this patient as “red flags” that should cause concern. Additional diagnostic testing is necessary. Certainly there are many causes of difficulty swallowing, but in this situation dysphagia and weight loss indicate that esophageal carcinoma must first be considered. This is not a patient with nonspecific upper GI symptoms who should simply be placed on a proton pump inhibitor (PPI) and followed.
PATIENT CARE
Clinical Thinking
• Establish if the swallowing problem is with solids, liquids, or both.
• Determine associated symptoms.
History
• A focused history should include timing of onset and duration of symptoms.
Physical Examination
• There are no specific physical examination findings.
• Assess whether there has been significant weight loss, and assess nutritional status.
Tests for Consideration
Clinical Entities | Medical Knowledge |
Achalasia |
|
Pφ |
Achalasia results from the inability of the lower esophageal sphincter (LES) to relax, as a result of a defect in the inhibitory motor neurons. The cause of primary achalasia is unknown. It affects about 1 in 100,000 persons. Chagas disease is an uncommon form of secondary achalasia and is acquired via infection with Trypanosoma cruzi. |
TP |
Patients complain at first of progressive dysphagia to solids, and then to both solids and liquids. Regurgitation can occur (usually at night) in the reclining or recumbent position. Chest pain is frequently a symptom. |
