Abstract

Background

Talc pleurodesis is an effective treatment for malignant pleural effusions (MPEs). This study was designed to estimate complication rates of thoracoscopic talc insufflation.

Methods

Literature search was conducted in electronic databases and studies were selected if they reported complication rates of thoracoscopic talc insufflation in cancer patients with MPEs. Meta-analyses of proportions were performed to obtain incidence rates of complications.

Results

Twenty-six studies (4482 patients; age 62.9 years [95% confidence interval (CI): 61.5, 64.4]; 50% [95% CI: 43, 58] females) were included. Intraoperative, perioperative, 30-day, and 90-day mortality rates were 0% [95% CI: 0, 1], 2% [95% CI: 0, 4], 7% [95% CI: 3, 13] and 21% [95% CI: 5, 43] respectively. Incidence rates [95% CI] of various complications were: pain (20% [1, 2]), fever (14% [3, 4]), dyspnea (13% [5, 6]), pneumothorax (6% [7, 8]) pneumonia (4% [0, 12]), emphysema (3% [3, 7]), prolonged air leakage (3% [0, 7]), prolonged drainage (3% [9, 10]), thromboembolism (3% [9, 11]), lung injury (2% [7, 12]), respiratory insufficiency (2% [0, 5]), re-expansion pulmonary edema (1% [0, 3]), empyema (1% [0, 2]), respiratory failure (0% [0, 1]), and acute respiratory distress syndrome (ARDS; 0% [0, 1].

Conclusions

Whereas pain and fever were the most frequent complications of thoracoscopic talc insufflation, the incidence of ARDS was low. Pneumothorax, pneumonia, emphysema, prolonged air leakage, pulmonary embolism, arrythmia, re-expansion pulmonary edema, and empyema are important complications of thoracoscopic talc insufflation.
