Mainstem to mainstem bronchial fistula from broncholithiasis

Area of Science:

• Pulmonology
• Rare Diseases
• Medical Case Reports

Background:

• Broncholithiasis is a rare condition characterized by calcified material eroding into the tracheobronchial tree, often stemming from granulomatous lymphadenitis.
• Symptoms like wheezing, chronic cough, and dyspnea can mimic common respiratory diseases, complicating diagnosis.
• Potential severe complications include massive hemoptysis, recurrent pneumonias, bronchiectasis, mediastinal abscess, and fistula formations.

Observation:

• This report details a patient with broncholithiasis.
• The patient underwent treatment using electrocautery forceps.
• A rare complication of a mainstem to mainstem bronchial fistula was observed post-treatment.

Findings:

• This is the first reported instance of a mainstem to mainstem bronchial fistula developing after electrocautery forceps treatment for broncholithiasis.
• Previous literature documented fistulas involving mediastinal, esophageal, or vascular structures, but not between mainstem bronchi.
• The case underscores the potential for unusual complications even with established treatment modalities.

Implications:

• The findings suggest that electrocautery forceps, while a treatment option, carries a risk of inducing rare bronchial fistulas.
• This case expands the spectrum of known broncholithiasis complications and treatment-related adverse events.
• Further investigation into the mechanisms and prevention of such fistulas is warranted for improved patient safety in managing broncholithiasis.
