Gastroesophageal RefluxNCT03077906
Study of Gastro-oesophageal Reflux in Patients Having Had Bariatric Surgery
An observational study of Gastroesophageal Reflux, run by Pierre Wauthy at 1 site in Belgium.
Trial summary
Obesity surgery has become commonplace nowadays. This type of surgery is in full swing and although it is mostly beneficial for the health of the patient (reduction of cardiovascular risks, improvement of self image, reduction of osteo-articular risks, etc...) it is however associated with risks.

About this study
Obesity surgery has become commonplace nowadays. This type of surgery is in full swing and although it is mostly beneficial for the health of the patient (reduction of cardiovascular risks, improvement of self image, reduction of osteo-articular risks, etc...) it is however associated with risks. There are several short and long term complications, excluding the ones related to the anesthesia and the post-op recovery: fistulas, abcesses, infections, dysphagia, risks of endobrachyoesophagus, etc...
The gastroœsophageal reflux remains by far the most common post-op complaint within patients. Patients can experience symptoms as far as 3 years after the surgery. Medical treatment alone can in most cases lighten the symptoms. However, in some cases, this treatment fails and another type of surgery (bypass) must be undertaken, which is psychologically traumatic for the patient.
This retrospective study will analyze a cohort of patients who underwent bariatric surgery (mainly sleeve gastrectomy), in order to identify those at risk of developping gastroœsophageal reflux and how this complication can be avoided in pre-op. The study will also identify cases of invalidating gastroœsophageal reflux that can be solved by obesity surgery.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Obesity surgery has become commonplace nowadays. This type of surgery is in full swing and although it is mostly beneficial for the health of the patient (reduction of cardiovascular risks, improvement of self image, reduction of osteo-articular risks, etc...) it is however associated with risks. There are several short and long term complications, excluding the ones related to the anesthesia and the post-op recovery: fistulas, abcesses, infections, dysphagia, risks of endobrachyoesophagus, etc...
The gastroœsophageal reflux remains by far the most common post-op complaint within patients. Patients can experience symptoms as far as 3 years after the surgery. Medical treatment alone can in most cases lighten the symptoms. However, in some cases, this treatment fails and another type of surgery (bypass) must be undertaken, which is psychologically traumatic for the patient.
This retrospective study will analyze a cohort of patients who underwent bariatric surgery (mainly sleeve gastrectomy), in order to identify those at risk of developping gastroœsophageal reflux and how this complication can be avoided in pre-op. The study will also identify cases of invalidating gastroœsophageal reflux that can be solved by obesity surgery.

Questions about this trial
What is this clinical trial studying?
An observational study of Gastroesophageal Reflux, run by Pierre Wauthy at 1 site in Belgium.
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 1 inclusion and 3 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: finished, as of the sponsor's last update on 22 Nov 2017. 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 Belgium. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
date of birth (time frame: 8 years). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03077906, which also lists 6 linked publications.
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 22 Nov 2017.
