Patient description (medical language): A 48-year-old man comes to the office complaining of heartburn and acid reflux.  He has taken over-the-counter antacids but sees no relief.  Other medical history is unremarkable.  The patient does not use tobacco, alcohol, or illicit drugs.  Vital signs are within normal limits.  BMI is 31 kg/m2.  Physical examination is  positive for mild tenderness in upper stomach. Chest x-ray shows an air-fluid opacity behind the heart.  A barium swallow study reveals approximately 1/3 of the stomach herniating through the esophageal hiatus.

Patient description (patient's own words): I went to my doctor's office because of a non-stop heartburn and some acid reflux. I took over-the-counter medications, but it keeps going strong! I don't smoke, take drugs or drink alcohol, I'm healthy! The doctor took my vitals, which turned out normal. My BMI is 31, which might be a bit too much for a 48-year-old guy like me. They examined my stomach and found a mild tenderness in the upper part. I also did some X-rays, and they found out that I have an air-fluid opacity behind my heart. I did another X-ray, and it turns out that a part of my stomach went up my chest through a hole in my diaphragm!

Does the patient match the trial criteria? Entailment
