Heartburn correlated to 24-hour pH monitoring and radiographic examination of the esophagus.
OBJECTIVE
Study relationship of gastroesophageal reflux disease to findings on radiographic examination of the esophagus.


METHODS
We correlated heartburn (HB) in 360 patients (174 women; 186 men; mean age, 53 yr) to results of pH monitoring (pHM) and radiographic examination of the esophagus. Radiographic findings were categorized as normal (n = 129), hiatal hernia (HH) only (n = 173), reflux esophagitis (n = 50), or peptic stricture (n = 8) (ES; 58). Abnormal pHM was defined as total percentage of esophageal acid exposure time (pH < 4) of 6% or greater.


RESULTS
pHM was abnormal in 41 (31%) of 132 patients with HB versus 54 (24%) of 228 without the symptom (p > 0.05). Radiographic correlation showed abnormal pHM in only 21 (16%) of 129 patients with a normal esophagus, 52 (30%) of 173 with HH, and 22 (38%) of 58 with ES, which was significantly lower for those with a normal esophagus. In 132 patients with HB, those with normal esophagus had lower abnormal pHM (2 of 38; 5%) compared with patients with HH (24 of 64; 38%) or with ES (15 of 30; 50%) (p < 0.05). In the 228 patients without HB, abnormal pHM was found in 19 (21%) of 91 with a normal esophagus, 28 (26%) of 109 with HH, and 7 (25%) of 28 with ES (p > 0.05).


CONCLUSIONS
(1) pHM findings did not correlate with presence or absence of HB; (2) pHM is usually normal in patients with normal esophagus on RE; (3) pHM is also usually normal in patients with HB and normal esophagus on RE; and (4) pHM is often normal in patients with radiographic findings of reflux esophagitis or peptic stricture.
