Abstract:
Objective:To analyze the clinical manifestations and esophageal motility characteristics of patients with gastroesophageal reflux disease (GERD) and extra-esophageal symptoms.Methods:From January 1 to October 30, 2018, at PLA Rocket Force Characteristic Medical Center, 180 hospitalized patients diagnosed with GERD and extra-esophageal symptoms were retrospectively analyzed. The patients were divided into laryngopharyngeal symptom group (65 cases), airway symptom group (58 cases) and mixed symptom group (57 cases). General data, clinical symptoms, gastroscopic manitestations, the results of high-resolution esophageal manometry and 24-hour multichannel intraluminal impedance and pH monitoring of each group were analyzed and compared. Chi-square test and one-way analysis of variance were used for statistical analysis.Results:The patients aged <40, 40 to 60 and >60 years accounted for 12.8% (23/180), 53.3% (96/180) and 33.9% (61/180), respectively, and the difference was statistically significant ( χ2=12.030, P=0.017). There were 18.9%(34/180) of patients without typical reflux symptoms. There were statistically significant differences in the incidence of ectopic esophagogastric mucosa or Barrett esophagus under gastroscopy between laryngopharyngeal symptom group, airway symptom group and mixed symptom group (21.5%, 14/65; 5.2%, 3/58 and 8.8%, 5/57, respectively) ( χ2=8.578, P=0.014). There were no statistically significant differences in the lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure or distal contractile integral between laryngopharyngeal symptom group, airway symptom group and mixed symptom group ((8.57±0.76), (8.87±0.79), and (10.51±0.97) mmHg (1 mmHg=0.133 kPa); (44.75±2.86), (42.81±4.06), and (39.14±3.20) mmHg; (506.13±64.30), (432.59±78.10), and (682.99±82.28) mmHg·s·cm)(all P>0.05). The DeMeester score of laryngopharyngeal symptom group , mixed symptom group and airway symptom group was (14.33±2.09), (21.94±5.30) and (30.47±5.85) points, respectively, and the difference was statistically significant ( F=3.226, P=0.043). The results of multi-channel impedance monitoring showed that acid reflux and weak acid reflux were the main reflux in the patients, which accounted for 55.5% (76/137) and 34.3% (47/137), respectively. Among 87.6% (120/137) of the patients, reflux mainly occurred in the upright position while 12.4% (17/137) of the patients had reflux in the supine position. Conclusions:The extra-esophageal symptoms of GERD is associated with age. Ectopic esophagogastric mucosa or Barrett esophagus are more common in GERD patients with laryngopharyngeal symptoms. There are more acid exposure and pathologic acid reflux in GERD mainly with airway symptoms. Weak acid reflux at upright position plays an important role in the reflux mechanism of GERD with extra-esophageal symptoms.
