Surgical options for malignant pleural effusion

1. Video-assisted thoracoscopic surgery (VATS) drainage, pleural biopsy, and talc poudrage pleurodesis
   • VATS permits complete drainage, inspection of the pleural cavity, directed biopsy if needed, adhesiolysis when feasible, and insufflation of sterile talc.
   • Appropriate for a symptomatic patient who is fit for surgery, whose lung is expected to fully re-expand, and who has a prognosis sufficient to benefit from durable pleurodesis.
   • Talc poudrage has high pleurodesis success rates. Schwartz's Principles of Surgery, p. 767.
2. Mechanical pleurodesis
   • Abrasion of the parietal pleura during VATS to provoke adhesion between visceral and parietal pleura.
   • May be combined with chemical talc pleurodesis, but is less commonly selected as a stand-alone approach for MPE.
   • It requires close pleural apposition, so it is unsuitable with trapped or non-expandable lung.
3. Pleurectomy
   • Parietal pleurectomy, usually via VATS or thoracotomy, removes pleura to limit recurrent fluid formation.
   • It is a relatively morbid option and is generally reserved for selected, surgically fit patients with longer expected survival who have failed less invasive treatment.
   • Sabiston Textbook of Surgery states that pleurectomy and pleurodesis are reserved for failure of other therapies in patients with reasonable life expectancy.
4. Decortication
   • Removal of the fibrous visceral pleural rind to allow an entrapped/non-expandable lung to expand.
   • Consider only in carefully selected, fit patients with symptomatic non-expandable lung, especially when there is a surgically correctable pleural peel.
   • The BTS pleural-disease guideline notes that decortication may improve pleurodesis success in selected patients, but treatment should be individualized against operative risk and the alternative of an indwelling pleural catheter.
5. Open thoracotomy procedures
   • Open pleurectomy or decortication may be required if VATS is not technically possible due to a very thick pleural peel, dense adhesions, or complex disease.
   • Usually avoided for routine MPE because the burden of surgery can outweigh benefit in advanced malignancy.
