Background: The aim of this study was to evaluate the safety and efficacy of medical thoracoscopy through a single port [single-port medical thoracoscopy (S-MT)] for the treatment of empyema thoracis in its early stages.
Methods: We performed a retrospective analysis reviewing the medical records of 84 patients referred for empyema and treated by medical thoracoscopy at our Thoracic Departments from January 2001 until November 2014. S-MT was performed under local anesthesia with neuroleptoanalgesia and spontaneous breathing using a single 1-cm incision for debridement and lavage of the pleural cavity.
Results: A total of 84 patients underwent S-MT for pleural empyema stage I (9 patients, 10.7%) or II (75 patients, 89.3%). Median age was 61.8 years (range, 18 to 84 y). Male to female ratio was 3.76. Surgery was performed 5 to 26 days after the onset of symptoms. Macroscopically complete debridement of the pleural cavity was achieved in 71 patients (84.5% of cases). The rest 15.5% of cases required video-assisted thoracoscopic surgery or open decortication due to trapped-lung syndrome. Median operation time was 45 minutes (range, 30 to 94 min). No intraoperative complications occurred. In-hospital mortality was zero, whereas in-hospital morbidity rate was 16.7%. Median hospital stay was 7.8 days (range, 3 to 18 days). Recurrence rate was 4.8% as 4 patients experienced a relapse of empyema.
Conclusion: It seems that S-MT is a minimally invasive, safe and effective procedure for the treatment of pleural empyema with very good results in early stages of the disease and reduced time of hospital stay.
