The assessment of the esophageal motility of children with esophageal disorders by the detailed observation of the pH–multichannel intraluminal impedance waveform and baseline impedance: screening test potential

Abstract

Background

The present study aimed to evaluate whether the detailed observation of pH/MII waveforms and the analysis of baseline impedance (BI) values could detect esophageal dysmotility in pediatric patients with esophageal disorders.

Patients and methods

Eleven patients with congenital esophageal disorder in whom pH/MII was conducted from April 2011 to June 2015, were enrolled in this study. The diagnoses of the patients were as follows: postoperative esophageal atresia (EA), n = 6; esophageal achalasia (EAch), n = 4; and congenital esophageal stenosis (CES), n = 1. The characteristics of the pH/MII waveform, pathological GERD, BI value, and the average BI value of the 2 distal channels (distal BI; DBI) were analyzed in each disorder.

Results

Two EA (33%) patients and one EAch (25%) patient were diagnosed with GERD. The mean DBI values of the EA, EAch and CES patients was 912 ± 550, 2153 ± 915 and 1392 Ω, respectively. The EA patients showed consistently low DBI values. One CES patient and two infantile EAch patients showed postprandial prolonged low DBI values. Whereas, the pH/MII waveforms of the adolescent EAch patients were difficult to interpret due to their extremely low BI values.

Conclusions

The present study demonstrated that the detailed observation of the pH/MII waveforms in all channels and the analysis of BI were useful for evaluating esophageal motility in children with congenital esophageal disorders. In particular, infantile patients with EAch showed DBI findings that were distinct from those of adult EAch patients. Considering the difficulty of performing esophageal manometry in young children, the detailed observation of the pH/MII waveform may help in the diagnosis of esophageal dysmotility in children.
