Pleuro-Pulmonary Tuberculosis - Surgical Principles

  1. 1. SURGICAL ASPECTS OF PLEUROPULMONARY TUBERCULOSIS Dr. SANJOY SANYAL MBBS, MS (Surgery) Department of Surgery – Central Hospital Kigali. Rwanda, Africa 1999 Presented at 2 nd Annual Conference of College of Gynaecology and Obstetrics of Rwanda, Kigali, Rwanda, Africa, on 5th – 6th May 1999
  2. 2. Bird’s-eye view <ul><li>TB, specifically PT , needs no introduction </li></ul><ul><li>ATT - drastic reduction in indications for surgical treatment </li></ul><ul><li>MDRT strains - 33-70% of all cases, depending on region </li></ul><ul><li>5-10% PT require surgical treatment </li></ul><ul><li>Post-WW II era-maximum strides in intra-thoracic surgery </li></ul>
  3. 3. The therapeutic spectrum <ul><li>Pulmonary tuberculosis </li></ul><ul><ul><li>90-95%-----ATT (prolonged, regular) </li></ul></ul><ul><ul><li>5-10%-------Require surgery </li></ul></ul><ul><li>Procedures of choice </li></ul><ul><ul><li>Pulmonary resection-------------90% </li></ul></ul><ul><ul><li>Thoracoplasty--------------------10% </li></ul></ul>TB : Tuberculosis; PT : Pulmonary Tuberculosis, ATT : Anti-Tuberculosis Treatment; MDRT : Multi-Drug Resistant Tuberculosis
  4. 4. Classification of Rx – Pulmonary <ul><li>Resection ---------Segmental resection </li></ul><ul><li>---------Lobectomy </li></ul><ul><li>---------Pneumonectomy </li></ul><ul><li>Relaxation (collapse) therapy </li></ul><ul><li>Major--------------Thoracoplasty </li></ul><ul><li>-------------- Plombage </li></ul><ul><li>--------------Pneumonolysis (extrapleural) </li></ul>
  5. 5. Classification – Cont’d <ul><li>Relaxation (collapse) therapy </li></ul><ul><li>Minor-----------Phrenic paralysis </li></ul><ul><li>----------- Pneumothorax </li></ul><ul><li>-----------Pneumoperitoneum </li></ul><ul><li>Drainage therapy </li></ul><ul><li>-----------Cavernostomy </li></ul><ul><li>-----------Monaldi catheter drainage </li></ul>
  6. 6. Thoracoplasty (Relax Rx) principle <ul><li>TB heals by fibrosis, contraction, collapse, obliteration of diseased area / cavity. </li></ul><ul><li>Bony chest wall mechanically hinders this. </li></ul><ul><li>Removal of sufficient portion of wall obliterates pleural space </li></ul><ul><li>Allows lung to contract / retract concentrically towards hilum, and thus ‘relax’ . </li></ul>
  7. 7. Thoracoplasty – Indications <ul><li>TB too widespread for safe removal </li></ul><ul><li>Resection unduly risky </li></ul><ul><li>‘ Open-positive’ with MDRT strains </li></ul><ul><li>Elderly patients-as ‘compromise’ procedure </li></ul><ul><li>Broncho-pleural fistula) following pul. resection-as ‘secondary’ procedure </li></ul><ul><li>Failed decortication of TB empyema </li></ul>
  8. 8. Thoracoplasty – Types <ul><li>Standard (extrapleural, paravertebral) thora-coplasty = selective (upper lobe); Alexander </li></ul><ul><li>Lateral thoracoplasty; Sauerbruch </li></ul><ul><li>Semb’s apicolytic modification </li></ul><ul><li>Apical thoracoplasty (adjunctive procedure) </li></ul><ul><li>Modified (‘tailoring’) thoracoplasty </li></ul><ul><li>Radical thoracoplasty; Friedrich </li></ul>
  9. 9. Pulmonary resection <ul><li>Aims: Remove / assist in healing / control of destructive residuals; prevent reactivation </li></ul><ul><li>Advantages: Greater diseased part removed; no external deformity; little respiratory disturbance </li></ul><ul><li>Disadv: Unsafe in extensive disease; inadvisable in MDRT strains . </li></ul><ul><li>(These are indications for thoracoplasty) </li></ul>
  10. 10. Pulmonary resection – Indications <ul><li>‘ Open-positive’ beyond 3-6 months of Rx </li></ul><ul><li>‘ Closed-positive’ with pathologic residuals </li></ul><ul><li>‘ Open-negative’ with thick-walled cavity </li></ul><ul><li>Negative sputum with blocked cavities / > 2 cm nodules / tuberculoma / fibrocaseous </li></ul><ul><li>TB bronchiectasis middle / lower lobe </li></ul>
  11. 11. Indications – Cont’d <ul><li>Atypical mycobacterial infection </li></ul><ul><li>Neoplasm -can’t differentiate / concomitant / cancer at site of TB scar </li></ul><ul><li>Haemoptysis -recurrent / persistent / massive </li></ul><ul><li>Encapsulated, un-expandable lobe / lung with empyema </li></ul>
  12. 12. Resection – Extent <ul><li>Wedge resection: Tuberculoma, coin lesion; for frozen section biopsy confirmation </li></ul><ul><li>Segmental resection: Localised residual cavities, fibrocaseous, especially bilateral </li></ul>
  13. 13. Resection – Extent <ul><li>Lobectomy: Active disease with +ve sputum and drug-resistant bacilli </li></ul><ul><li>Pneumonectomy: Gross destruction one lung, persistent +ve sputum, recurrent haemoptysis </li></ul>
  14. 14. Resection – Complications <ul><li>Empyema, with or without }When +ve spu- </li></ul><ul><li>Broncho-pleural fistula }tum, drug-resi- </li></ul><ul><li>Bronchogenic spread of TB }stant, or exten- </li></ul><ul><li>}sive resection Adjunctive procedures </li></ul><ul><li>Temporary phrenic nerve paralysis </li></ul><ul><li>Small apical thoracoplasty </li></ul>
  15. 15. Childhood resection <ul><li>Vast majority respond to long-term ATT </li></ul><ul><li>Only 5% require resection for: </li></ul><ul><ul><li>Progressive primary TB </li></ul></ul><ul><ul><li>Reinfection TB </li></ul></ul><ul><ul><li>Destructive residuals </li></ul></ul><ul><li>Lobar atelectasis or emphysema due to hilar nodes don’t need operation. </li></ul><ul><li>With ATT nodes regress and lobes become normal </li></ul>
  16. 16. TB empyema – Aims of Rx <ul><li>Control of infection by : </li></ul><ul><ul><li>Regular needle aspiration (thoracentesis) </li></ul></ul><ul><ul><li>Intrapleural and systemic ATT </li></ul></ul><ul><li>Open drainage should be avoided </li></ul><ul><ul><li>(2° infection of pleural space inevitable) </li></ul></ul>
  17. 17. Aims of Rx – Cont’d <ul><li>Obliteration of empyema cavity </li></ul><ul><li>a) Active lung infection : </li></ul><ul><ul><li>ATT for 3-6 months </li></ul></ul><ul><ul><li>Followed by thoracoplasty or pleuro-pneumonectomy </li></ul></ul><ul><li>b) Inactive lung infection : </li></ul><ul><ul><li>Repeated thoracentesis (prolonged) </li></ul></ul><ul><ul><li>Decortication (procedure of choice) </li></ul></ul>
  18. 18. Decortication – Principle <ul><li>Much better alternative to drainage </li></ul><ul><li>Aim: Early expansion of lung </li></ul><ul><li>Principles of technique: </li></ul><ul><li>Incising empyema sac, evacuating purulent contents, excising ‘peel’; OR </li></ul><ul><li>Excising entire empyema sac in toto from ‘outside - inwards’. </li></ul>
  19. 19. Decortication – Illustration
  20. 20. Combined procedures <ul><li>Pleuro-lobectomy or pleuro-pneumonectomy </li></ul><ul><ul><li>If TB empyema associated with active pulmonary disease (cavitation, positive sputum or both) </li></ul></ul><ul><li>Pleuro-pneumonectomy and eventual thoracoplasty </li></ul><ul><ul><li>If TB empyema with broncho-pleural fistula and secondary pathogenic infection </li></ul></ul>
  21. 21. Conclusion Decortication and pleuro- pneumonectomy have dramatically altered outlook in most cases and have rendered all other procedures obsolete.
