High-resolution Esophageal Manometry

January 30, 2018 updated by: CECILIA CURVALE, Hospital El Cruce

High-resolution Esophageal Manometry in Teenagers With Esophageal Atresia

EA is one of the most frequent birth defects, with an incidence of 1 in 3000 live births1. Until the 1950s, these patients had 100% mortality; nowadays, the survival rate is greater than 90%, and only those with associated severe malformations die1-5.

Type C EA (atresia of the esophageal proximal segment with tracheoesophageal fistula between the trachea and the distal segment) is the most common variant, since it is present in 85% of the cases6-8. There is evidence that the esophageal motor disorder present in these children is secondary to a congenital neuromuscular disorder and a postoperative disorder9-14. Patients that survive the operation have greater risk of developing gastroesophageal reflux disease (GERD), caused by anomalies in the esophageal motility and its resulting delay in the evacuation of acid of the esophageal lumen.

There was a hypothesis that suggested that motility alteration could contribute to dysphagia and to the high prevalence of gastroesophageal reflux in these patients15-18. Also, there were reports of a greater incidence of severe esophagitis with requirement of fundoplication, which shows a larger failure rate17-18. Esophageal dysmotility has been proved in children with EA through performance of conventional perfusion manometry.

Lemoine C et al described three motility alteration patterns with HRM in children with repaired EA. Said study allowed a more precise knowledge of segmental esophageal motility19. Currently, there are no reports exclusively made about teenagers with repaired EA that describe segmental esophageal motility with HRM.

Study Overview

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
September 1, 2017

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.

First Submitted That Met QC Criteria

First Submitted That Met QC Criteria

The date on which the study sponsor or investigator first submits a study record that is consistent with National Library of Medicine (NLM) quality control (QC) review criteria.
