Aerodigestive Fistulas in Adults at the University Hospital of Strasbourg (FAD'HUS)

December 9, 2025 updated by: University Hospital, Strasbourg, France

Aerodigestive Fistulas in Adults: Management at the Strasbourg University Hospital Between 2014 and 2023

Acquired aerodigestive fistulas in adults are rare conditions, corresponding to a pathological communication between the digestive and respiratory tracts, requiring collaborative multidisciplinary management. Clinical manifestations are nonspecific, ranging from a simple cough to pulmonary sepsis, which can be life-threatening. Diagnosis is often multimodal, requiring radiological examinations and endoscopic investigations. The most frequent etiologies are divided into two groups: benign and malignant causes, each group representing 50% of all acquired aerodigestive fistulas. Among the benign etiologies, 75% are iatrogenic, mainly represented by complications related to orotracheal intubation. These fistulas of benign etiology most often have a favorable prognosis, amenable to surgical treatment. Conversely, the development of an aerodigestive fistula in the context of thoracic cancer marks a turning point in the evolution of the oncological disease. Indeed, the average life expectancy of patients with a malignant fistula is estimated at between 1 and 6 weeks without specific treatment. Following this palliative approach aimed at improving quality of life, multiple treatment options are available, often combined with digestive and thoracic endoscopy.

The Strasbourg University Hospitals are a leading tertiary care center for these pathologies, with departments of Pulmonology, Gastroenterology, Digestive Surgery, Thoracic Surgery, Medical Intensive Care, Multipurpose Surgical Intensive Care, Bronchial Endoscopy, and Digestive Endoscopy. The centre's influence extends over the entire eastern part of the Grand Est region (Nancy, Metz, Strasbourg, Mulhouse).

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.

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.
November 21, 2024

Primary Completion (Estimated)

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.

Study Completion (Estimated)

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.
