Esophageal Reflux

Case Studies

A 45-year-old woman complained of heartburn and frequent regurgitation of “sour” material into

her mouth. Often while sleeping, she would be awakened by a severe cough. The results of her

physical examination were negative.

Diagnostic Analysis

The barium swallow indicated a hiatal hernia. Although many patients with a hiatal hernia have

no reflux, this patient’s symptoms of reflux necessitated esophageal function studies. She was

found to have a hypotensive LES pressure along with severe acid reflux into her esophagus. The

abnormal acid clearing and the positive Bernstein test result indicated esophagitis caused by

severe reflux. The esophagitis was directly visualized during esophagoscopy. Her coughing and

shortness of breath at night were caused by aspiration of gastric contents while sleeping. This

was demonstrated by the gastric nuclear scan. When awake, she did not aspirate, as evident

during the swallowing function study. The patient was prescribed esomeprazole (Nexium). She

was told to avoid the use of tobacco and caffeine. Her diet was limited to small, frequent, bland

feedings. She was instructed to sleep with the head of her bed elevated at night. Because she had

only minimal relief of her symptoms after 6 weeks of medical management, she underwent a

laparoscopic surgical antireflux procedure. She had no further symptoms.

Critical Thinking Questions

1. Why would the patient be instructed to avoid tobacco and caffeine?

2. Why did the physician recommend 6 weeks of medical management?

3. How do antacid medication work in patients with gastroesophageal reflux?

4. What would you approach the situation, if your patient decided not to take the medication

and asked you for an alternative medicine approach?
