METHODS Seventy-five consecutive patients with suspectedgastroesophageal reflux disease(GERD) underwent 24-h combined MII-p HM recording and one hour radionuclide scintigraphy during the course of the MIIpH M study. Catheters with 6 impedance channels and 1 p H sensor were placed transnasally. Impedance and p H data analysis were performed automatically and manually. For impedance monitoring, reflux was defined as a retrograde 50% drop in impedance, starting distally and propagating retrogradely to at least the next two more proximal measuring channels. Reflux index(RI, percentage of the entire record that esophageal p H is < 4.0) greater than 4.2% for p HM and number of refluxes more than 50 for 24 h for MII were accepted as positive test results. At scintigraphy, 240 frames of 15 seconds duration were acquired in the supine position. Gastroesophageal reflux was defined as at least one reflux episode in the esophagus. After scintigraphic evaluation, impedance-pH recordings and scintigraphic images were evaluated together and agreement between tests were evaluated with Cohen's kappa.RESULTS Sufficient data was obtained from 60(80%) patients(34 male, 56.7%) with a mean age of 8.7 ± 3.7 years(range: 2.5-17.3 years; median: 8.5 years). Chronic cough, nausea, regurgitation and vomiting were the most frequent symptoms. The mean time for recording of MII-pH M was 22.8 ± 2.4 h(range: 16-30 h; median: 22.7 h). At least one test was positive in 57(95%) patients. According to diagnostic criteria, GERD was diagnosed in 34(57.7%), 44(73.3%), 47(78.3%) and 51(85%) patients by means of p HM, MII, GES and MII-p HM, respectively. The observed percentage agreements/κ values for GES and p HM, GES and MII, GES and MII-p HM, and MII and p HM are 48.3%/-0.118; 61.7%/-0.042; 73.3%/0.116 and 60%/0.147, respectively. There was no or slight agreement between GES and p HM alone, MII alone or MII-p HM. p H monitoring alone missed 17 patients compared to combined MII-p HM. The addition of MII to pH monitoring increased the diagnosis rate by 50%.CONCLUSION No or slight agreement was found among p H monitoring, MII monitoring, MII-pH monitoring and GES for the diagnosis of gastroesophageal reflux disease.展开更多
