Early and late outcome after diagnostic thoracoscopy and talc pleurodesis

Although thoracoscopy is now recognized to be of both diagnostic and therapeutic value, the risks of this procedure have not been fully addressed. We retrospectively reviewed our experience with 100 patients who underwent 110 thoracoscopies during the period January 1989 to February 1991. Sixty-five men and 35 women (ratio of 1.9:1) underwent thoracoscopy using general anesthesia and intubation with a double-lumen endotracheal tube. The mean age was 64.2 +/- 11.6 years (range, 13 to 85 years). The diagnosis was established in 48 (85.7%) of the 56 patients with undiagnosed pleural effusions. Forty-four patients were referred for therapeutic thoracoscopic talc pleurodesis. Pleurodesis was successful in 42 patients (95.5%). Four patients (4%) had five postoperative complications (two bronchopleural fistulas, two chest infections, and one arrhythmia). Five patients (5%) died after thoracoscopy; mean age was 67.8 +/- 8.1 years (range, 55 to 77 years). The causes of death were cardiac arrest in 2, respiratory failure in 1, and malignant cachexia in 2. The findings of this study confirm that thoracoscopy can achieve high rates of diagnostic and therapeutic success but is not without attendant mortality in a high-risk patient population.
