What this trial studies

This study evaluates the feasibility and safety of using disposable endobronchial silicon spigots for patients suffering from refractory pneumothorax, which is characterized by persistent air leaks despite standard treatment. The research involves a single-group, single-center design and aims to preliminarily assess the efficacy of this innovative bronchial occlusion technology. A total of 10 patients will be included, all of whom must meet specific eligibility criteria related to their condition and treatment history.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with persistent air leaks from pneumothorax after 7 days of intercostal drainage.

Not a fit: Patients with silicone allergies or contraindications for bronchoscopy will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new, effective treatment option for patients with refractory pneumothorax.

How similar studies have performed: This approach is novel and has not been extensively tested in prior studies.

Eligibility criteria

Inclusion Criteria:

* Subjects must meet all of the following criteria to be enrolled:

  1. Male or female, aged ≥18 years;
  2. Patients with various types of pneumothorax who still have persistent air leaks after continuous intercostal drainage for 7 days;
  3. After evaluation by the researcher, the subject is feasible for the bronchoscopic procedure of selective bronchial occlusion to treat refractory pneumothorax, and the responsible bronchus can be determined by the balloon detection;
  4. Voluntarily participate in this trial and sign an informed consent form.

Exclusion Criteria:

* Subjects with any of the following conditions cannot be selected:

  1. Allergic to silicone materials;
  2. Contraindications for bronchoscopy:

     * Myocardial infarction within the past month;
     * Active massive hemoptysis;
     * Platelet count \<20×10\^9/L;
     * Pregnancy;
     * Malignant arrhythmias, unstable angina, severe cardiopulmonary dysfunction, hypertensive crisis, severe pulmonary arterial hypertension, intracranial hypertension, acute cerebrovascular events, aortic dissection, aortic aneurysm, severe mental illness, and extreme systemic exhaustion, etc.
  3. Uncontrolled acute pulmonary infection or severe chronic infection at the intended occlusion lobes or segments;
  4. Obvious hemodynamic instability or unstable respiratory failure;
  5. The responsible bronchus cannot be determined by balloon detection;
  6. The researcher believes that the patient has other conditions that are not suitable for inclusion in this study.
