METHODS:Five hundred and fifty patients who presented to the outpatient clinic of Turkiye Yuksek Ihtisas Hospital with gastroesophageal reflux disease-like symptoms were enrolled.Each individual was evaluated with esophageal manometry,24-h ambulatory pH monitoring,and upper gastrointestinal endoscopy. Manometric findings for the patients with isolated distal reflux were compared to findings in controls who were free of reflux disorders or hypersensitive esopha- gus.Findings for isolated distal reflux patients with and without erosive reflux disease were also compared. RESULTS:Of the 550 subjects enrolled,97(17.6%, mean age 48 years)had isolated distal reflux and 100 had no abnormalities on ambulatory pH monitoring (control group,mean age 45 years).There were no significant differences between the isolated distal reflux group and control group with respect to age,body mass index,and esophageal body contraction amplitude (EBCA).Mean lower esophageal sphincter pressure was significantly higher in the control group(12.7±10.3 mmHg vs 9.6±7.4 mmHg,P=0.01).Fifty-five(56.7%) of the 97 patients with isolated distal reflux had erosive reflux disease.There were no statistical differences be- tween the erosive reflux disease and non-erosive reflux disease subgroups with respect to mean EBCA,lower esophageal sphincter pressure,or DeMeester score.However,13%of patients with gastroesophageal reflux disease had distal wave amplitudes≤30 mmHg, whereas none of the patients with non-erosive reflux disease had distal wave amplitudes in this low category. CONCLUSION:Patients with erosive and non-erosive disease present with similar manometric abnormalities. The only striking difference is the observation of very low EBCA exclusively in patients with erosive disease. 关 键 词：反流 食管 远端 孤立 压结 患者 胃
