A 55-year-old male presents with a 2-month history of progressive difficulty swallowing solids, initially, and now liquids. He reports unintentional weight loss of 10 pounds over the past 2 months. He denies heartburn or regurgitation. Which of the following is the most appropriate initial diagnostic test?
- AEsophageal manometry
- BUpper endoscopy with biopsy
- C24-hour esophageal pH monitoring
- DBarium swallow study
Show answer & explanationAnswer & explanation
Correct answer: B. Upper endoscopy with biopsy
The patient's 'alarm symptoms' (progressive dysphagia, especially for solids, and significant unintentional weight loss) strongly suggest an underlying structural or malignant cause, such as esophageal cancer. Upper endoscopy with biopsy is the most crucial initial test as it allows direct visualization of the esophageal mucosa and tissue sampling for definitive diagnosis.
Why the other options are wrong
- A. Esophageal manometry assesses motility disorders but is not the first-line test when alarm symptoms suggest a structural/malignant cause.
- C. 24-hour pH monitoring is used for GERD assessment and is not indicated as the initial test for progressive dysphagia with weight loss.
- D. A barium swallow can identify structural abnormalities but cannot provide tissue for biopsy, which is critical with alarm symptoms.
Dysphagia with Alarm Symptoms Workup
For patients presenting with dysphagia accompanied by 'alarm symptoms' such as unintentional weight loss, anemia, or progressive symptoms, prompt upper endoscopy with biopsy is the initial diagnostic test of choice to rule out malignancy or other serious structural causes.
- Alarm symptoms warrant urgent investigation.
- Progressive dysphagia (solids then liquids) is concerning for malignancy.
- Upper endoscopy provides direct visualization and tissue biopsy.
