What is bronchial fistula closure via bronchoscopy — and how does it work?
A bronchial fistula is an abnormal channel between a bronchus (one of the main airways branching from the windpipe) and an adjacent space — most often the pleural cavity surrounding the lung, but sometimes the oesophagus or the skin surface. The opening allows air, secretions or fluid to pass where they should not, causing persistent cough, breathlessness, recurrent chest infections and, in severe cases, collapsed lung tissue. Bronchial fistula closure via bronchoscopy seals that abnormal channel from the inside using a thin flexible or rigid tube — the bronchoscope — passed through the mouth or nose under sedation or general anaesthesia, without any incision in the chest wall. The bronchoscopist advances the scope to the fistula site and delivers a closure agent or device directly into the opening: options include endobronchial valves, biological glues (fibrin sealant), coils, plugs or bronchoscopic electrocautery, depending on the size, location and cause of the fistula. For the full range of respiratory and thoracic procedures available see our pulmonology treatments in Turkey.
Because no chest incision is made, bronchoscopic closure is particularly valuable for patients who are too unwell or frail to tolerate open or video-assisted thoracic surgery (VATS). It is used both as a definitive treatment and as a bridge — stabilising the patient while the underlying lung heals enough for a later surgical repair if needed.
How the bronchoscopic closure procedure is performed, step by step
The sequence varies slightly with the closure technique chosen, but the general steps are as follows.
- Assessment and imaging: CT of the chest and, often, bronchoscopy under sedation map the fistula's exact location, size and direction before any treatment is planned.
- Anaesthesia: Most procedures use general anaesthesia with a protected airway; smaller fistulas and sealant applications are sometimes done under deep sedation with topical anaesthesia of the airway.
- Bronchoscope insertion: A flexible bronchoscope (or rigid bronchoscope for larger work) is passed through the mouth, through the vocal cords and into the bronchial tree under continuous camera guidance.
- Fistula identification: The opening is located; methylene blue dye or balloon occlusion tests confirm the exact site.
- Closure delivery: The chosen agent or device — endobronchial valve, fibrin glue, synthetic plug, coil or combination — is deployed directly into or over the fistula opening.
- Confirmation: The team checks visually and, where possible, with pressure testing that the closure is airtight before the scope is withdrawn.
- Duration: Procedure time is typically 30–90 minutes depending on complexity.
After the procedure the patient is monitored in a recovery area, usually for several hours; many patients stay in hospital overnight or for a few days while chest drainage is confirmed to be reducing.
Does bronchoscopic fistula closure work — what does the evidence say?
For small to medium bronchopleural fistulas arising after pneumonia, lung resection or chest trauma, bronchoscopic closure achieves clinically meaningful sealing in a majority of cases when the technique and agent are well matched to the fistula size and type. Endobronchial valves, in particular, have good evidence in peer-reviewed literature for post-surgical air leaks. Biological sealants (fibrin glue) have a long clinical track record in Europe and are supported by thoracic surgery society guidelines as a first-line option for small fistulas.
The evidence is less robust for very large fistulas (greater than about 8 mm), fistulas caused by active infection or tumour erosion, or oesophagobronchial fistulas; in those situations bronchoscopic treatment is often considered a temporising measure rather than a cure, and surgical or interventional radiology options may eventually be needed. No single technique is universally effective: success depends on fistula aetiology, size, site, the patient's overall respiratory reserve and the experience of the bronchoscopist. A thorough pre-procedure assessment should include an honest discussion of the probability of closure and what happens if the first attempt is incomplete.
Bronchial fistula closure via bronchoscopy cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for the bronchoscopic procedure including anaesthesia and a short hospital stay, not quotes from individual centres. Costs vary with fistula complexity, the technique used, the number of sessions required and what is included in the package.
| Country | Approximate cost range |
|---|---|
| Turkey | €2,500 – €7,000 |
| United Kingdom | €6,000 – €16,000 |
| United States | €8,000 – €22,000 |
| Germany | €5,500 – €14,000 |
What drives the price: the technique used (a valve or dedicated plug costs more than sealant alone), whether one or several bronchoscopic sessions are needed, the length of hospital stay, pre-procedure CT and lung-function testing, and post-procedure chest drain management. A written package quote from a Turkish centre typically covers the bronchoscopy, anaesthesia, the closure device or agent, hospital stay, standard pre-operative tests and coordination. Confirm in writing whether a repeat session, should it be needed, is included or priced separately. To start the process, use our free quote page.
Bronchoscopic closure compared with surgical fistula repair
Both approaches aim to seal the fistula; they differ in invasiveness, risk profile and the patient population each suits.
| Approach | Best suited to | Typical limitations |
|---|---|---|
| Bronchial fistula closure via bronchoscopy | Small to medium fistulas; patients unfit for surgery; post-resection air leaks; first-line or bridging treatment | Lower closure rate for large or complex fistulas; may need repeat sessions |
| Open surgical repair (thoracotomy) | Large or complex fistulas with healthy surrounding tissue; failed bronchoscopic closure | Significant surgical trauma; requires good cardiorespiratory reserve |
| Video-assisted thoracic surgery (VATS) | Fistulas accessible with minimally invasive thoracoscopy; moderate fitness | Still requires general anaesthesia and chest incisions; not suitable for all locations |
The choice between these approaches is not always fixed: bronchoscopic closure and surgical repair are sometimes used sequentially, with bronchoscopy used first to reduce air leak and allow the patient to recover before definitive repair. Understand our coordination process to see how the team presents you with the most appropriate option for your situation.
Who is a suitable candidate — and who may not be?
Bronchoscopic closure is typically considered for patients who have a confirmed bronchopleural or bronchocutaneous fistula with an identifiable bronchoscopic entry point, adequate airway anatomy for scope access, stable or improving systemic condition, and who are either unfit for surgery or prefer to avoid it as a first step. It is particularly used after pulmonary resection (lobectomy, pneumonectomy), after severe pneumonia or lung abscess, and following chest trauma.
Patients for whom bronchoscopic closure is less likely to succeed or less appropriate include those with very large fistulas (the airway defect is too wide to plug reliably), fistulas caused by active tumour invading the airway wall, oesophagobronchial fistulas of significant size, uncontrolled active infection at the fistula site, or severely compromised coagulation. The treating team should give a candid assessment of expected success for your specific fistula before you agree to a procedure.
What to expect during your stay in Turkey and during recovery
Most patients travelling to Turkey for bronchoscopic fistula closure plan for a stay of seven to fourteen days, depending on how the fistula responds. The first one to two days involve final imaging and lung-function review; the procedure itself takes place on day two or three. After bronchoscopy the chest drain output is monitored; a consistent reduction in air leak is the main sign that closure is working. If the drain stops bubbling and can be safely removed, discharge is usually within four to seven days of the procedure. If a second session is recommended, the team will discuss whether this can be done during the same trip.
Once home, most patients resume light activities within one to two weeks. Strenuous exertion, heavy lifting and air travel should be avoided until the respiratory team confirms the closure is stable — typically at a follow-up CT or bronchoscopy four to eight weeks later. Full recovery from the underlying lung condition that caused the fistula varies considerably; the bronchoscopic closure is one part of ongoing respiratory management, not a standalone cure.
Realistic results: what bronchoscopic closure can and cannot achieve
A successful closure reduces or eliminates the abnormal air leak, allows the pleural space to heal, reduces the risk of recurrent pneumonia seeding through the fistula tract, and in many cases avoids a major operation. For post-resection fistulas, bronchoscopic closure has allowed patients to avoid re-operation in a substantial proportion of cases reported in thoracic surgery literature.
What bronchoscopic closure does not do: it does not restore lung tissue that was lost to disease, infection or surgery, and it does not address the underlying cause of the fistula. If the fistula arose because of persistent infection, tumour or poor tissue healing, those issues require parallel treatment. Ask to see the centre's data on closure rates for fistulas of a similar size and cause to yours, and ask what the plan is if the first attempt does not fully seal the opening.
Risks and complications
Bronchoscopic fistula closure is less invasive than open surgery, but it is not risk-free. Known complications include incomplete closure requiring repeat procedures, displacement or migration of a valve or plug into the airway, worsening bronchospasm or coughing during the procedure, transient reduction in oxygen levels under sedation, bleeding from the airway mucosa, and infection introduced during the procedure. As with any intervention requiring sedation or general anaesthesia, cardiovascular events are possible, especially in patients with pre-existing heart or lung disease. Professional thoracic societies — including the European Respiratory Society (ERS) and the British Thoracic Society (BTS) — advise that bronchoscopic interventions for fistula are performed in centres with thoracic surgery backup available, so that if a complication requires open management, it can be addressed promptly. Ask the centre what their protocol is if bronchoscopic closure fails or if a complication arises that requires surgical management.
Questions to ask the clinic before you book
- How many bronchoscopic fistula closures has your team performed, and what is your closure rate for fistulas of my size and type?
- Which technique — valve, glue, plug or combination — do you recommend for my fistula, and why?
- Is thoracic surgical backup available on site if the bronchoscopic approach fails or causes a complication?
- How many sessions might I need, and is a second session included in the quoted price?
- What imaging will you repeat after the procedure to confirm closure?
- What is the plan if the fistula is not fully sealed after the first attempt?
- What follow-up do you provide once I return home, and who do I contact if symptoms return?
How to choose a centre and red flags to watch for
Confirm that the centre offering bronchial fistula closure via bronchoscopy has an accredited interventional pulmonology or thoracic endoscopy unit with experienced bronchoscopists and that thoracic surgery is available within the same facility. The centre should provide a written procedure plan covering the technique, expected number of sessions, hospital stay and price before you agree to anything. Red flags include vague claims of a guaranteed seal, no discussion of what happens if the procedure fails, quotes with no itemised breakdown, no named bronchoscopist, and no mechanism for communicating with the team after you return home.

Frequently asked questions
It is a minimally invasive procedure in which a bronchoscope — a thin flexible or rigid camera tube — is passed through the airway to locate an abnormal opening (fistula) in the bronchus and seal it using a valve, biological glue, plug or coil, without any incision in the chest wall.
For small to medium post-surgical or post-infectious fistulas it achieves clinically meaningful closure in a majority of patients when the technique is well matched to the fistula type. Very large fistulas or those caused by active tumour are harder to seal bronchoscopically and may ultimately need surgical repair.
Approximate ranges are €2,500 to €7,000 in Turkey, compared with roughly €6,000 to €16,000 in the UK. The exact price depends on fistula complexity, the closure device used, the number of sessions needed and the length of hospital stay; each centre confirms its price in a written quote.
Most patients remain in hospital for four to seven days after the procedure while the chest drain output is monitored. Light activity resumes within one to two weeks of returning home; strenuous exertion is avoided until the team confirms stable closure, usually at a follow-up scan four to eight weeks later.
Plan for seven to fourteen days in total, covering pre-procedure imaging, the bronchoscopy, post-procedure monitoring until the drain can be removed, and the team's check before you fly. A second session, if needed, may extend the stay.
The airways are anaesthetised and most procedures are done under general anaesthesia or deep sedation, so there is no pain during the procedure. Afterwards patients may have a sore throat, mild chest discomfort and coughing, which usually settles within a few days.
Bronchoscopic closure uses a camera tube through the mouth to seal the fistula from inside the airway with no chest incision, making it suitable for patients unfit for surgery. Open repair or VATS involves chest incisions and is usually reserved for large or complex fistulas, or after bronchoscopic closure has not fully succeeded.
Known risks include incomplete closure, displacement of a valve or plug, airway bleeding, bronchospasm, oxygen-level changes under sedation and, rarely, cardiovascular events. The procedure is less risky than open surgery but should be performed in a centre with thoracic surgical backup available.
Procedure time is typically 30 to 90 minutes depending on fistula complexity, the technique used and whether a balloon occlusion test is needed to confirm the site before closure.
A successful closure reduces or stops the abnormal air leak, allows the pleural space to heal and reduces the risk of recurrent infection through the fistula tract. It does not restore lost lung tissue or address the underlying cause; ongoing respiratory management is usually needed alongside the closure.
