Introduction
A small cohort of patients present after antireflux surgery complaining of recurrent heartburn. Over two thirds of these patients will have a negative 24-h pH study. The aim of our study is to determine whether these patients have an associated functional disorder or abnormal cytokine activity and to examine the reproducibility of pH testing.
Methods
A prospective analysis was carried out on a cohort of patients who had undergone a fundoplication and postoperative pH testing for recurrent heartburn: group A—patients with recurrent heartburn and a negative 24-h pH study and group B (control group)—patients with recurrent heartburn and a positive pH study. Questionnaires, a blood sample, and repeat pH testing were completed.
Results
Sixty-nine patients were identified. Group A’s depression score (8.6 ± 4.1) was significantly higher than group B’s (5.9 ± 4.2; P = 0.03). Cytokine levels were similar in both groups. Forty-seven of 49 (96%) patients who underwent repeat pH testing had a negative study. Symptom-reflux correlation was highly significant (P < 0.001).
Conclusion
Some patients with recurrent heartburn and a negative pH study have associated functional or psychiatric comorbidities such as depression. Reproducibility of 24-h pH testing in these patients is excellent.
