Trial summary

Patients with gastroesophageal reflux disease (GERD) may present with concomitant gas-related symptom (GRS) such as supragastric or gastric belching, and aerophagia. Identifying these patients is crucial, as their therapeutic pathway differs substantially from that of patients with "pure" reflux disease. Read more about this study

About this study

Patients with gastroesophageal reflux disease (GERD) may present with concomitant gas-related symptom (GRS) such as supragastric or gastric belching, and aerophagia. Identifying these patients is crucial, as their therapeutic pathway differs substantially from that of patients with "pure" reflux disease. Proceeding directly to antireflux surgery in the presence of untreated air-associated symptoms can lead to catastrophic postoperative outcomes. These partly behavioral disorders can often be effectively managed through targeted speech therapy. Following successful therapy, patients may either experience complete resolution of their symptoms or become suitable candidates for surgical treatment of GERD. As of today, there is very scarce literature on this subject.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of air-associated symptoms and their impact on daily life before and after targeted speech and language therapy in patients with GERD, assessed using a specifically developed patient questionnaire.

    Comparison of air-associated symptoms and their impact on daily life before and after targeted speech and language therapy in patients with GERD.

    Measured: From start of speech therapy until interview: - Speech therapy was started earliest in January 2023, latest around January 2026. - Interviews are taking place starting in April 2026 until all have been performed, end is anticipated in fall 2026.

Questions about this trial

What is this clinical trial studying?

An observational study of GERD, run by Prof Urs Zingg at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 11 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparison of air-associated symptoms and their impact on daily life before and after targeted speech and language therapy in patients with GERD, assessed using a specifically developed patient questionnaire. (time frame: From start of speech therapy until interview: - Speech therapy was started earliest in January 2023, latest around January 2026. - Interviews are taking place starting in April 2026 until all have been performed, end is anticipated in fall 2026.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jun 2026.
