چکیده
Introduction Prolonged acid reflux monitoring using wireless pH (WPM) may be performed following impedance in suspected false negative cases. The increased yield of Gastro-esophageal disease (GERD)-positive diagnoses with WPM is unknown. Also unknown which parameters from the or manometry, predict a subsequent positive test. Aim: a) Determine and b) determine predictors GERD positivity patients GERD-negative impedance. Methods GERD-positive diagnostic was determined 181 consecutive who had undergone HRM. Univariate multivariate analysis WPM. Results Of included, average day 61 studies were for (Male : Female 26: 35, age 47 (15) years 120 (Male:Female 52: 68 48 years. This corresponds to 33.70% initially diagnosed as not having GERD, being given diagnosis at Using worst analysis, impedance, 62 (34.25%). 92% on also analysis. 20 (33.33%) classified WPM-GERD-positive only 1 day. number that first 24 hours study 19 (31.15%) 11 (18.03%) respectively. univariate significant differences found basal respiratory minimum (mmHg) (GERD positive: 8 (8),GERD negative: 10 (8) p=0.010), episodes positive:20 (14) 12 (11) p=0.001) exposure time positive:1.70 (1.35) 1.07 (1.14) p=0.002) between groups. Only significantly associated WPM-GERD result (OR:0.95 (0.90, 1.00)). Conclusions There after related presence intermittent these patients. Predictability difficult ascertain HRM 24-hour variables. suggests longer period assessment rather than different refluxate components beneficial: more formal assess difference detection useful.

Combined pH-metry/impedance monitoring increases the diagnostic yield in patients with atypical gastroesophageal reflux symptoms.
BACKGROUND Globus sensations, hoarseness and chronic cough are suggested to be atypical manifestations of Gastroesophageal Reflux Disease (GERD). The aim of the study was to investigate whether combined pH-metry and multichannel intraluminal impedance monitoring increases the diagnostic yield. METHODS 41 patients with atypical GERD symptoms were included in the study. Globus sensation was the...
متن کاملEsophageal pH and Combined Impedance-pH Monitoring in Children
Esophageal pH monitoring is considered the gold standard for the diagnosis of gastroesophageal reflux disease because of the normal ranges across the pediatric age range. However, this method can only detect acid reflux. Multichannel intraluminal impedance-pH (MII-pH) monitoring has recently been used for the detection of bolus reflux in infants and children. This method allows for the detectio...

BACKGROUND/AIMS Respiratory symptoms are often associated with gastroesophageal reflux disease (GERD). Although the role of multichannel intraluminal impedance-pH (MII-pH) monitoring in GERD is clear, little is known regarding the characteristics of patients with respiratory symptoms based on MII-pH monitoring and anti-reflux therapy. We evaluated a cohort of GERD patients to identify the MII-p...
متن کاملCombined Esophageal Intraluminal Impedance, pH and Skin Conductance Monitoring to Detect Discomfort in GERD Infants
BACKGROUND The clinical significance of weakly acidic reflux in infants is unclear. Skin conductance is a novel not-invasive method to evaluate discomfort. The aim of our study was to evaluate reflux-induced discomfort in infants with gastroesophageal reflux disease using simultaneously combined skin conductance and esophageal multichannel intraluminal impedance and pH monitoring.
