Hypothesis
Is there a relationship between acid regurgitation and persistent cough after pulmonary resection?
Conclusion
There is a relationship between acid regurgitation and persistent cough in some patients shortly after surgery, but most did not show improvement in acid regurgitation after one year.
Supporting Evidence
- 10 out of 10 patients in the Type A group had a symptom association probability greater than 95%.
- 8 out of 10 patients with persistent coughing improved after treatment with medication.
Takeaway
Some people cough a lot after lung surgery because of acid coming up from their stomach, but even after treatment, many still cough a year later.
Methodology
Patients underwent 24-hour esophageal pH monitoring to assess acid regurgitation and its relationship with coughing.
Limitations
The study may have been affected by irritability from the pH monitoring procedure.
