Bronchopleural Fistula Management (ESTS/Literature 2024)

Algorithm Steps

1. ▶

   Start

   Suspected Bronchopleural Fistula

   Post-lung resection patient with persistent air leak or new pneumothorax

   1. ●

      Action

      Clinical Presentation

      Recognize BPF signs

      • EARLY BPF (day 1-7): usually mechanical failure
      • • Sudden large air leak
      • • Subcutaneous emphysema
      • • Tension physiology possible
      • LATE BPF (>7 days): usually infection-related
      • • Fever, cough with purulent sputum
      • • Productive cough laying on operative side
      • • Empyema with air-fluid level
      1. ●

         Action

         Diagnostic Workup

         Confirm BPF and assess size

         • CXR: new pneumothorax, air-fluid level change
         • CT chest: localize fistula, assess stump
         • Bronchoscopy: visualize stump, size fistula
         • Incidence (ESTS database):
         • • Overall: 1.9%
         • • Lobectomy: <1%
         • • Pneumonectomy: 4-20%
         1. ◆

            Decision

            Timing & Size of BPF?

            Guides management approach

            • EARLY (1-7 days): mechanical failure → surgery
            • INTERMEDIATE (8-30 days): infection → drainage + consider surgery
            • LATE (>30 days): chronic → bronchoscopic or staged surgery
            1. ●

               Action

               Early BPF (Day 1-7)

               Mechanical stump failure

               • URGENT SURGICAL RE-EXPLORATION
               • • Stump revision/re-closure
               • • Buttress with viable tissue
               • - Intercostal muscle flap
               • - Pericardial fat pad
               • - Omentum
               • Best outcomes with early repair
               1. ●

                  Action

                  Surgical Repair

                  Definitive closure

                  • Stump revision with tissue coverage:
                  • • Intercostal muscle flap (most common)
                  • • Latissimus dorsi flap
                  • • Serratus anterior flap
                  • • Omental transposition
                  • May require completion pneumonectomy
                  • if residual lung non-functional

                     Outcome

                     Fistula Closed / Cavity Managed

                     Long-term: pulmonary rehab, surveillance

            2. ●

               Action

               Late BPF (>7 days)

               Usually infection-related, staged approach

               • STEP 1: Sepsis control
               • • Open window thoracostomy (Eloesser flap)
               • • OR chest tube + irrigation
               • • VAC therapy to clean cavity
               • STEP 2: Fistula closure (once clean)
               • • Bronchoscopic intervention if small
               • • Surgical muscle flap if larger
               1. ●

                  Action

                  VAC Therapy

                  For cavity management

                  • Negative pressure wound therapy to:
                  • • Clear empyema cavity
                  • • Promote granulation
                  • • Reduce cavity size
                  • May allow eventual muscle flap closure
                  • or space obliteration
               2. ●

                  Action

                  Bronchoscopic Interventions

                  For small fistulas or poor surgical candidates

                  • Options:
                  • • Fibrin glue
                  • • Endobronchial valves (one-way valves)
                  • • Amplatzer device
                  • • Coils
                  • • Sclerotherapy
                  • Success rate: variable, best for <8mm defects
                  • Often temporizing measure
         2. ⚠

            Warning

            ⚠️ HIGH MORTALITY

            BPF mortality 16-72%. Early aggressive management improves outcomes.

         3. ●

            Action

            Initial Stabilization

            All patients

            • Chest tube drainage (if not present)
            • Position: operative side DOWN
            • Broad-spectrum antibiotics
            • Nutritional support
            • NPO if aspiration risk
